The market for data science is ripe right now and if you are a data scientist or interested in becoming one then you should be putting your pedal to the metal and explore the applications of Data Science Training Institute in Hyderabad in defense.
Biochar is a carbon-rich, fine-grained residue which can be produced either by ancient techniques (such as covering burning biomass with soil and allowing it to smoulder) or state-of-the-art modern biomass pyrolysis processes. Combustion and decomposition of woody biomass and agricultural residues results in the emission of a large amount of carbon dioxide. Biochar can store this CO2 in the soil leading to reduction in GHGs emission and enhancement of soil fertility.
Biochar holds the promise to tackle chronic human development issues like hunger and food insecurity, low agricultural productivity and soil depletion, deforestation and biodiversity loss, energy poverty, water pollution, air pollution and climate change. Let us have a close look at some of the most promising applications of biochar.
1. Use of biochar in animal farming
At present approx. 90% of the biochar used in Europe goes into animal farming. Different to its application to fields, a farmer will notice its effects within a few days. Whether used in feeding, litter or in slurry treatment, a farmer will quickly notice less smell. Used as a feed supplement, the incidence of diarrhoea rapidly decreases, feed intake is improved, allergies disappear, and the animals become calmer.
In Germany, researchers conducted a controlled experiment in a dairy that was experiencing a number of common health problems: reduced performance, movement disorder, fertility disorders, inflammation of the urinary bladder, viscous salivas, and diarrhoea. Animals were fed different combinations of charcoal, sauerkraut juice or humic acids over periods of 4 to 6 weeks.
Experimenters found that oral application of charcoal (from 200 to 400 g/day), sauerkraut juice and humic acids influenced the antibody levels to C. botulinum, indicating reduced gastrointestinal neurotoxin burden. They found that when the feed supplements were ended, antibody levels increased, indicating that regular feeding of charcoal and other supplements had a tonic effect on cow health.
2. Biochar as soil conditioner
In certain poor soils (mainly in the tropics), positive effects on soil fertility were seen when applying untreated biochar. These include the higher capacity of the soil to store water, aeration of the soil and the release of nutrients through raising the soil’s pH value. In temperate climates, soils tend to have humus content of over 1.5%, meaning that such effects only play a secondary role.
Indeed, fresh biochar may adsorb nutrients in the soil, causing at least in the short and medium term – a negative effect on plant growth. These are the reasons why in temperate climates biochar should only be used when first loaded with nutrients and when the char surfaces have been activated through microbial oxidation.
The best method of loading nutrients is to co-compost the char. This involves adding 10–30% biochar (by volume) to the biomass to be composted. Co-composting improves both the biochar and the compost. The resulting compost can be used as a highly efficient substitute for peat in potting soil, greenhouses, nurseries and other special cultures.
Because biochar serves as a carrier for plant nutrients, it can produce organic carbon-based fertilizers by mixing biochar with such organic waste as wool, molasses, ash, slurry and pomace. These are at least as efficient as conventional fertilizers, and have the advantage of not having the well-known adverse effects on the ecosystem. Such fertilizers prevent the leaching of nutrients, a negative aspect of conventional fertilizers. The nutrients are available as and when the plants need them. Through the stimulation of microbial symbiosis, the plant takes up the nutrients stored in the porous carbon structure and on its surfaces.
A range of organic chemicals are produced during pyrolysis. Some of these remain stuck to the pores and surfaces of the biochar and may have a role in stimulating a plant’s internal immune system, thereby increasing its resistance to pathogens. The effect on plant defence mechanisms was mainly observed when using low temperature biochars (pyrolysed at 350° to 450°C). This potential use is, however, only just now being developed and still requires a lot of research effort.
3. Biochar as construction material
The two interesting properties of biochar are its extremely low thermal conductivity and its ability to absorb water up to 6 times its weight. These properties mean that biochar is just the right material for insulating buildings and regulating humidity. In combination with clay, but also with lime and cement mortar, biochar can be added to clay at a ratio of up to 50% and replace sand in lime and cement mortars. This creates indoor plasters with excellent insulation and breathing properties, able to maintain humidity levels in a room at 45–70% in both summer and winter. This in turn prevents not just dry air, which can lead to respiratory disorders and allergies, but also dampness and air condensing on the walls, which can lead to mould developing.
As per study by the Ithaka Institute’s biochar-plaster wine cellar and seminar rooms in the Ithaka Journal. Such biochar-mud plaster adsorbs smells and toxins, a property not just benefiting smokers. Biochar-mud plasters can improve working conditions in libraries, schools, warehouses, factories and agricultural buildings.
Biochar is an efficient adsorber of electromagnetic radiation, meaning that biochar-mud plaster can prevent “electrosmog”. Biochar can also be applied to the outside walls of a building by jet-spray technique mixing it with lime. Applied at thicknesses of up to 20 cm, it is a substitute for Styrofoam insulation. Houses insulated this way become carbon sinks, while at the same time having a more healthy indoor climate. Should such a house be demolished at a later date, the biochar-mud or biochar-lime plaster can be recycled as a valuable compost additive.
4. Biochar as decontaminant
As a soil additive for soil remediation – for use in particular on former mine-works, military bases and landfill sites.
Soil substrates – Highly adsorbing and effective for plantation soil substrates for use in cleaning wastewater; in particular urban wastewater contaminated by heavy metals.
A barrier preventing pesticides getting into surface water – berms around fields and ponds can be equipped with 30-50 cm deep barriers made of biochar for filtering out pesticides.
Treating pond and lake water – biochar is good for adsorbing pesticides and fertilizers, as well as for improving water aeration.
5. Use of biochar in wastewater treatment – Our Project
The biochar grounded to a particle size of less than 1.5 mm and surface area of 600 – 1000 m2/g. The figure below is the basic representation of production of biochar for wastewater treatment.
We conducted a study for municipal wastewater which was obtained from a local municipal treatment plant. The municipal wastewater was tested for its physicochemical parameters including pH, chemical oxygen demand (COD), total suspended solids (TSS), total phosphates (TP) and total Kjeldahl nitrogen (TKN) using the APHA (2005) standard methods.
Bio filtration of the municipal wastewater with biochar acting as the bio adsorbent was allowed to take place over a 5 day period noting the changes in the wastewater parameters. The municipal wastewater and the treated effluent physicochemical.
The COD concentration in the municipal wastewater decreased by 90% upon treatment with bio-char. The decrease in the COD was attributed to the enhanced removal of bio contaminants as they were passed through the biochar due to the biochar’s adsorption properties as well as the high surface area of the bio char. An 89% reduction in the TSS was observed as the bio filtration process with bio char increased from one day to five days
The TKN concentration in the wastewater decreased by 64% upon treatment with bio char as a bio filter. The TP in the wastewater decreased by 78% as the bio filtration time with biochar increase. The wastewater pH changed from being alkaline to neutral during the treatment with biochar over the 5 day period
6. Use of Biochar in Textiles
In Japan and China bamboo-based biochar are already being woven into textiles to gain better thermal and breathing properties and to reduce the development of odours through sweat. The same aim is pursued through the inclusion of biochar in shoe soles and socks.
Waste management has a profound impact on all sections of the society, and military is no exception. With increasing militarization, more wars and frequent armed conflicts, protection of the environment has assumed greater significance for military in armed conflicts as well as peacetime operations. Tremendous amount of waste is generated by military bases and deployed forces in the form of food waste, papers, plastics, metals, tires, batteries, chemicals, e-waste, packaging etc.
War on Waste
Sustainable management of waste is a good opportunity for armed forces to promote environmental stewardship, foster sustainable development and generate goodwill among the local population and beyond. Infact, top military bases in the Western world, like Fort Hood and Fort Meade, have an effective strategy to counter the huge amount of solid waste, hazardous waste and other wastes generated at these facilities.
Waste management at military bases demands an integrated framework based on the conventional waste management hierarchy of 4Rs – reduction, reuse, recycling and recovery (of energy). Waste reduction (or waste minimization) is the top-most solution to reduce waste generation at military bases which demands close cooperation among different departments, including procurement, technical services, housing, food service, personnel. Typical waste reduction strategies for armed forces includes
making training manuals and personnel information available electronically
reducing all forms of packaging waste
purchasing products, such as food items, in bulk
purchasing repairable, long-lasting and reusable items
Due to large fraction of recyclables in the waste stream, recycling is an attractive proposition for the armed forces. However, environmental awareness, waste collection infrastructure, and modern equipment are essential for the success of any waste management strategy in a military installation.
Food waste and yard waste (or green waste) can be subjected to anaerobic digestion or composting to increase landfill diversion rates and obtain energy-rich biogas (for cooking/heating) and nutrient-rich fertilizer (for landscaping and gardening). For deployed forces, small-scale waste-to-energy systems, based on thermal technologies, can be an effective solution for disposal of combustible wastes, and for harnessing energy potential of wastes. In case of electronic wastes, it can be sent to a Certified Electronics Recycling and Disposal firm.
Key Aspect
Management options for military installations is dependent on size of the population, location, local regulations, budgetary constraints and many other factors. It is imperative on base commanders to evaluate all possible options and develop a cost-effective and efficient waste management plan. The key factors in the success of waste management plan in military bases are development of new technologies/practices, infrastructure building, participation of all departments, basic environmental education for personnel and development of a quality recycling program.
Military installations are unique due to more than one factor including strict discipline, high degree of motivation, good financial resources and skilled personnel. Usually military installations are one of the largest employers in and around the region where they are based and have a very good influence of the surrounding community, which is bound to have a positive impact on overall waste management strategies in the concerned region.
Printed circuit boards play an essential role in many industries. And with the speedy growth of the energy field and the innovation of complex machines, building of high quality PCBs is needed.
In a growing sector such as the renewable energy industry, lead-free and quality PCBs are needed. Below are the three vital circuit board types that are used in the renewable energy industry.
Printed Circuit Board used in Renewable Energy Industry
1. Heavy Copper PCB
A heavy copper printed circuit board has a very heavy copper circuit. It is a type of circuit board subjected to specialized etching and plating techniques.
Heavy copper PCB has great features that make it ideal for high-end applications in the renewable energy industry. For instance, it is heavier and thicker to handle higher voltage and power.
Benefits of heavy copper PCB

Applications of heavy copper PCBs
Heavy copper PCBs can be used in various renewable energy industries such as solar energy, military, aerospace, geothermal, and many others.
2. Multilayer PCBs
A multilayer PCB is a circuit board with 3 or more conductive copper foil layers. It uses more single-sided or double-sided circuit boards to enhance circuit wiring. The number of layers of a multilayer PCB can be four, six, eight, ten, and up to a hundred layers.
Due to the numerous benefits of multilayer PCBs, renewable energy industries are among the beneficiaries of the boards. Multilayer PCBs have more conductive layers to achieve better electrical performance.
Benefits of multilayer PCBs
a. Smaller size
One advantage of using multilayer PCBs in the renewable energy sector is that they are small in size. This means they encourage manufacturers to build smaller gadgets that do not use a lot of energy.
b. Lightweight
Compared to other printed circuit boards, multilayer PCBs are not heavy. This means they can be used in smaller devices that are mostly found in the renewable energy sector.
c. High durability
Multilayer PCBs are more reliable than single-layer and double-layer PCBs. Since there are no external wires and connectors, the boards are clean and tidy. In addition, they are made to withstand temperature stress, and pressure.
d. Fast performance
Since multilayer PCBs do not use wires and jumpers, the distance between layers is very minimal. This means the performance of the boards is commendable.
Applications of multilayer PCBs
For many industries such as renewable energy industries, multilayer PCBs have become the best option for a wide range of applications. Some of the applications of multilayer PCBs include consumer electronics, telecommunications, computer electronics, and many others.
3. Rigid-flex PCBs
Rigid-flex PCBs are circuit boards designed to act as replacements for rigid circuit boards. And as the name suggests, rigid-flex PCBs are hybrids of flex and rigid circuits. This means they display the benefit of rigid PCBs and flex PCBs.
Several rigid-flex PCBs consist of multiple layers of flexible circuit substrates normally attached to rigid boards externally or internally. They are designed to fit in applications that may require both flex and rigid circuit boards.
Advantages of rigid-flex PCBs
The combination of rigid PCBs and flexible PCBs makes it a beneficial product for many applications. Here are the main advantages of rigid-flex PCBs.
a. Flexible design alternatives
A rigid-flex PCB is a board that accepts any component and connector that can be assembled on the board. Hence, manufacturers can be flexible when designing or coming up with new ideas.
b. Reduction in size and weight of the package
Reduction in the weight and size of products is a policy that is adopted by renewable energy industries. Hence, rigid-flex PCBs are preferred in the industry because the combination of flex and rigid boards helps you to simplify your design.
c. Reduction in assembly cost
Since there are fewer connections and parts, the assembly cost is minimized. In addition, the development of the board’s prototype is significantly reduced thus minimizing the product cost of production.
Applications of rigid-flex PCBs
The main applications of rigid-flex PCBs are medical equipment, the telecommunication industry, the automotive industry, and consumer appliances among others.
Tips to choose a supplier for your project
Below are vital tips to look into when choosing a PCB supplier for your application.
1. The supplier should have a proper set of guidelines
To avoid serious mistakes, a good supplier should have a proper set of guidelines. With the guidelines, the company will be able to maintain repeatability during the whole production process.
Moreover, the PCB supplier must be ready to show the guidelines to the client so that the client can be satisfied.
2. Check the type and quality of the machines
Due to the growth of technology, the printed circuit board industry has added new designs and ideas. Hence, the supplier should use the latest equipment and software to ensure the boards are up to the latest standards, such as lamination, CNCmilling, photo process and so on.
3. Use of green materials
When choosing a supplier to produce PCB type to be used in the renewable energy industry, you need to ensure the elements are lead-free. Hence, the company should be committed to using green materials when manufacturing PCBs.
4. Know the order size and time limit they offer
Before mass production, you require prototypes. Hence, it is essential to check whether your PCB supplier can manage the prototypes and produce small quantities before hiring them.
You need to understand that time is a crucial element in any part of a business. Hence, the supplier should be able to handle all the due dates effectively.
Bottom Line
With the rapid growth of the energy industry and the innovation of more complex equipment, PCB suppliers are building high-quality PCBs to support complex machines. The circuit boards must be reliable, small in size, and made of lead-free components.
Hence, it is important when choosing a supplier to make sure they are committed to using green material when making PCBs.
The use of drones, also known as unmanned aerial vehicles (UAVs), dates back to 1849. Austria invaded Venice, sending human-contactless balloons over the city, which contained explosive materials. Advancements in drone technology allow for continued military utilization, as well as commercial and civilian use.
Drones recently joined the environmental industry, providing promising future aid to renewable energy development and maintenance. The small ascending computers can provide us with unique images of Earth, as natural TV programs show us. Drones may use their imaging abilities to survey and map the land and detect renewable energy system issues. They can also produce their own energy and limit package delivery emissions. Read on to know about the use of drones in renewable energy sector:
Surveying and Mapping
When evaluating potential renewable energy sites, like solar and wind farms, it is essential to calculate possible interference. Drones can move throughout these regions collecting data on wind currents, sun exposure, and the ecosystem. This system is integrated into the agricultural industry with light detection and ranging sensors (Lidar) attached to drones.
Renewable power companies use this system to survey and map energy sites. Like the Quantum Trinity F90+, popular commercial UAVs can reduce the time and greenhouse gases used in traditional land mapping practices. These devices can fly for 90-minute periods and track large regions of land.
Issue Detection
Once renewable energy systems are in place, drone use continues. Wind turbines benefit greatly from UAV intervention.
Most turbines reach heights of 280 feet to allow for maximum wind capture. Unfortunately, this poses severe problems for maintenance workers. In the U.K., 163 workers suffered injuries while repairing wind power devices, and five workers died.
UAVs can reach heights of 400 feet, allowing them to evaluate issues safely and effectively. These detection methods are less expensive for renewable energy companies and enable workers to plan more efficient repairs. One can also use drones to detect solar panel problems.
Solar companies use UAVs to detect panel malfunctions from the ground. To increase the sustainability of this practice and to reduce occupational accidents, companies can send drones to panel sites without workers present. This would further reduce greenhouse gas emissions by limiting the transportation process associated with maintenance.
Renewable Energy Drone Production
A recent development in the UAV industry allows drones to fuel themselves using wind power. The Saildrone is a device that harnesses its energy from small propellers, similar to the head of a wind turbine. Scientists are currently using them to collect and relay oceanic data, but their abilities are expanding.
Wind power-converting drones may act as a sustainable alternative to wind turbines. The UAVs in production fly in circular patterns with a kite attached. This maximizes the efficiency of wind capturing.
The energy would reach the Earth’s surface through an extended power cable, which is less environmentally disruptive than a turbine. The materials utilized in building a wind energy drone are less disruptive to the planet and require less greenhouse gas emissions in production.
Solar Delivery Drones
In 2013, Amazon revealed its idea to utilize drones to deliver packages efficiently. These UAVs would reportedly fly boxes to your doorstep in under 30 minutes, depending on your region. The incorporation of drones into the delivery industry could significantly reduce carbon emissions, preserving the atmosphere.
With renewable energy-powered delivery UAVs, truck-induced air pollution, traffic congestion, and roadkill could decrease. Limiting these environmental harms can conserve the environment and increase biodiversity on Earth. You may ask yourself, “So, where are my sustainably delivered packages?”
Drone Regulations
The reason that, eight years later, we are still waiting for our drone-delivered Amazon purchases has to do with strict aircraft regulations. Each year, the U.S. government releases new guidelines for commercial UAV use. These regulations restrict further drone use by the renewable energy industry.
Restrictions on flying heights, speed, weight, certifications, site navigation, and more limit one’s ability to use UAVs for sustainability purposes. Innovators are working to develop green drone uses, but it will take time before they reach the commercial market. As their safety and abilities increase, the use of drones in renewable energy sector will grow at a rapid pace.
You have probably come across glow sticks at some stage of your life, however other people refer to them as chemlights or light sticks. After you bend a glow stick, the glass inside shatters and it begins to glow.
After they begin to glow, you can expect them to be visible in the dark from 1 to 12 hours. The time of how long it glows for depends on the quality and the size of the glow stick.
Remember, that once you have broken the glass inside and the light appears, you can’t turn it off.
You can find glow sticks in all different types of shapes and sizes. Most are no longer than 10 inches, however some you can connect together to make longer ones. They are also available in lots of different colors, such as red, blue, yellow and orange. However, it seems both the orange and red don’t light up that well.
If you are planning to go out in the wild, it is vital that you pack reliable lighting. For several years, it has been common for people to use glow sticks in a crisis situation.
Unlike other sources of lighting, glow sticks don’t need batteries to work. Purchasing a quality glow stick will give you 12 hours of light, without having to worry about the batteries running out.
Glow sticks are safe, so you don’t have to worry about them starting a fire nor will they electrocute somebody. They are even safe for children to play with.
Because they are small and lightweight, you will easily be able to find space when you are packing.
Even the best quality glow sticks are cheap. If you are looking for value, purchasing glow sticks in bulk is your best option.
What Survival situations would a Glow Stick prove useful?
There are many reasons why you should pack a glow stick with your survival kit such as:
Keeps large groups together: At night it is very hard to organize a lot of people, so a glow stick will prove to be a very helpful device
After a road accident, you can use a glow stick as a marker: Glow sticks are a great way to warn oncoming traffic that there is an accident on the roadside. If there is debris on the road or gas leaks, placing a glow stick nearby will alert others.
Avoid falling: If you frequently camp, you have probably tripped at some stage. Small holes, trees, and other obstacles that are not visible during the night can cause injuries. By putting a glow stick nearby will help warn others. You can also place glow sticks to mark a safe path.
If it is raining or you are in the water, don’t worry as glow sticks are water-resistant and are perfect for wet environments.
Glow sticks are used by militaries all over the globe as a survival tool. If you do decide to buy glow sticks in bulk and you pack a large amount in your survival kit, you can easily write SOS with them if you are stuck in a dangerous location.
How do you dispose of Glow Sticks and are they safe?
One of the disadvantages of using glow sticks is that there is no environmentally safe way that you can recycle them. As each one has chemicals inside, the plastic casing cannot be reused nor can it be repurposed.
The reason why glow sticks produce light is that there are two main ingredients that cause a chemical reaction.
Although the casing is made of strong plastic, be careful of young children or pets chewing on the plastic. Although the chemicals are not that toxic, it is not advised to ingest them. If a child swallows some of the chemicals, make sure to rinse his or her mouth immediately. Speak to your doctor if the child has swallowed a lot.
Glow sticks have a shelf life of around 4 years, as long as it is kept in its original foil packaging. If it has been removed, you can expect it to last for 1 year. If you decide to buy in bulk, keep this in mind. If you have a large number of glow sticks and think they are out of date, test one before you throw them all away.
Glow sticks are not just a great source of lighting, but children and families can play lots of games and have a fantastic time with them.
If you are buzzed off with all the hype going around in the name of Bitcoin, which does not ring a bell to you, well, it’s high time to update the knowledge-scape about Bitcoin, the big buzz of the era, and cryptocurrencies, the next-gen currency system. Bitcoin is nothing but a set of programming codes designed by a developer under the pseudonym of Satoshi Nakamoto in 2009. Bitcoin is a digital currency with no physical existence, and any government or central authority does not govern it. Every new official trading platform is mined by solving extremely difficult programming puzzle works, which is done through advanced computers.
Bitcoin and Blockchain Technology
Blockchain technology is designed based on a chain of data blocks that are immutable. This ledger holds a comprehensive database of each transaction in Bitcoin, which has been made since its introduction in the cryptocurrency world.
The inherent characteristic feature is that this ledger is decentralized and immutable. Since it is a peer-to-peer network and is a public ledger, there are different modes of operation from which participating members of the Bitcoin community record every transaction, mining and feeding it to blocks.
However, even though it’s publicly accessible, once data is recorded, it cannot be changed or tampered with. Every participant at every node across the network is vital in validating every transaction, such as fund transfers, trades, mining, etc. However, no transaction can disappear, despite which many hackers have successfully anonymously stolen digital currencies. Therefore, crypto exchanges are nowadays more stringent with their security policies and measures.
Fast Processing of Bitcoin
Traditional transfers of funds operated through central authorities like banks need to go through a lengthy verification process. Therefore, they take time. However, Bitcoin, in comparison, is much faster. Since every crypto transaction in a blockchain is immutable and cuts off the need for a middleman to process it, the entire process of transactions and transfer of funds is easier, faster, and more convenient.
Bitcoin Acceptance
It is quite an obvious fact that it is difficult to accept when you are not accustomed to or known to a service or system. After the launch of the first cryptocurrency, that is Bitcoin, and it took a bit of time to kick start, to get the market ready to accept this new digital currency. Over mere 13 years, Bitcoin has made huge achievements with e-commerce and even physical stores, restaurants, and salons, accepting cryptocurrencies against their services.
There are a lot of big brands which has changed the game for Bitcoins by accepting Bitcoin as payment for their services as well as by investing in Bitcoins. Microsoft, Overstock, Amazon, and PayPal are worth mentioning who played a vital role in lifting the market value cap for Bitcoins with their vital business decision of investing and accepting Bitcoins.
It is not false that there have been setbacks for Bitcoin too. For example, at the beginning of 2021, Tesla, the automobile manufacturing brand, announced to accept Bitcoins for their new range of Tesla cars. However, soon around mid of a year, Elon Musk, the owner of Tesla, declined his plans to accept and invest in Bitcoins, which led to a great price drop of Bitcoins in August 2021. Another instance is the governmental ban imposed by China on cryptocurrency investments and transactions throughout the country which also impacted the growth rate of Bitcoins.
However, potential good media reports were also highlighted in the recent past, like the Ukrainian government spending $15 million of donated cryptocurrency on different needs and supplies for the military. Besides, small-scale and mid-scale businesses are prominently taking a progressive step in accepting cryptocurrencies for services.
Approximately 40% of military equipment suppliers, food packages, food chains, protective gear, and other military equipment accept cryptocurrency throughout Europe and the US. Cryptocurrency platforms are also exhibiting potential growth of investors in crypto trading. According to a recent survey report, the global share and size of the digital currency market are projecting a growth trajectory of $1.44 billion in 2020 to an estimated rise of $2.73 billion in 2025.
Wrapping it up !!!
Here we have highlighted all the key developments in the crypto world. You should always refer to all such developments when planning investment in the crypto market.
Electric mobility is the newest trend in today’s highly competitive market. Electric vehicles have already been defined as the future of transportation, and are on the increase. They are predicted to inevitably take over the car industry by the next decade.
Through technical innovation, e-Mobility is prepared to address today’s concerns linked with climate change, fossil fuel dependency, and environmental protection. Today, a slew of big auto manufacturers have not only begun building their own electric vehicles — alongside the industry’s pioneer, Tesla — but have also planned to discontinue the production of gas-powered vehicles in the next decades.
Vacuum technology has been – and still is – essential in this process.

What is the role of vacuum technology in the development of electric vehicles?
Vacuum is already used in various functional stages and processes associated with electric mobility. From the electrolyte-filling stage of a lithium-ion battery (to ensure that the cell is evenly saturated with the electrolyte) to assisting in the shaping of the electric motor with constantly innovative generator technologies, to make them modular, lighter, more affordable, quieter, and more efficient. Agilent is involved in the development and production of a vast majority of electric vehicle components.
In addition to lithium-ion batteries, the most known and utilized rechargeable batteries, Agilent concentrates as well on the advancements in hydrogen fuel cells, one of the future trends for innovative technologies in electric vehicles.
What are lithium batteries?
Modern lithium-ion batteries are the favoured technology for electric vehicles right now. Unlike other batteries, lithium-ion batteries are among the most often used rechargeable batteries because they have a much higher energy density and a slow discharge rate, allowing them to maintain a charge for significantly longer.
They are innovative battery technologies that utilize lithium ions as a key component in the battery’s operation and electrochemistry.
Lithium-ion batteries, in addition to appearing in electric cars, can also be found in small portable electronics such as laptops and smartphones, and are frequently utilized in military and aerospace applications.
Vacuum Technology is driving electric mobility!
Vacuum is already used in various functional stages and processes associated with electric mobility. Let’s go deep together in the stages where vacuum is the dominant player.
1. Battery production: vacuum technology in more than half of the battery manufacture processes!
Agilent’s vacuum specialists assist lithium-ion battery manufacturers with their procedures and technological challenges in production processes, quality control, and safety measurements. As a result, they have been significantly involved in the development of electric mobility, with their vacuum tech currently accounting for more than half of the processes in battery creation.
Battery performance, longevity, and overall quality are all highly influenced by the quality of the manufacturing process. Agilent solutions and experience optimize resource usage and reduce process time while ensuring product quality goals are fulfilled.
2. Battery Cooling
As batteries get more efficient and powerful, car companies are being pressed to develop new heat management systems. Cooling systems must keep battery temperatures between 20 and 40 degrees Celsius. Liquid coolers have been shown to be the most efficient approach for keeping the battery pack at the proper temperature range.
The biggest disadvantage of liquid coolers is the potential of a leak or spillage. Undetected leaks significantly reduce the battery’s service life and/or allow highly reactive electrolytes to escape. Water leakage in battery coolers is a severe problem that affects battery durability and battery pack safety. To ensure long battery life, the cell must be completely leak-proof.
To confirm leak-proofness, a leak test is performed using a vacuum leak detection instrument, which can detect even the slightest leak using helium as tracer gas and detecting it by means of an embedded mass spectrometer. Highly sensitive helium leak detection systems play an important role in the production of lithium batteries and bear a significant amount of responsibility in terms of safety.
3. Heating, Ventilation, and Air Conditioning (HVAC) systems
There isn’t a heat-producing engine in an electric vehicle. Differently to low efficiency thermal engines, high-performance electric motors generate very little heat. The vehicle cabin temperature must be raised by other means. So, how do electric vehicles generate heat?
Well, it needs to produce interior heat using — you got it — electricity. Often via one or more resistive heating elements. Early electrical automobiles in fact employed basic resistive heaters, while contemporary vehicles have heat pump systems that transport thermal energy from the outside into the interior.
These technological HVAC systems necessitate extensive vacuum and leak detection solutions in order to create strong and dependable components capable of successfully capturing and directing heat. Look at how the leak-proofness is tested here.
4. Electric motor
Electric vehicle manufacturers research innovative motor/generator technology to make them more modular and efficient, lighter, quieter and even cheaper than typical electric motors. Water is the principal enemy of electric and electronic parts, hence leak detection and humidity tightness are an absolute priority in all of them. Agilent helium leak detectors enable faster and more exact leak location and monitoring for completely sealed electric vehicle motors.
5. Electric and electronic components
The operating range of an electric vehicle is not just determined by battery capacity. New materials and procedures are being applied to manage higher voltage, temperatures, and insulation difficulties in order to improve the efficiency of a car’s internal electrical distribution.
In propulsion-grade power electronics, inverters, connections, filters, busbars, and safety devices all play important roles.
Insulating or environmental coatings are required for all of these components. Agilent is proud to supply diffusion and turbomolecular pumps for innovative coating equipment. Browse the Agilent website to find the best turbopumps and turbomolecular pumps.
Fuel cells are another zero-emission alternative to combustion engines and even to lithium batteries. This intriguing technology works with hydrogen gas: hydrogen is employed in fuel cells to generate power through a chemical process instead of combustion, with just water and heat as byproducts. Hydrogen reacts electrochemically in fuel cells to produce electricity and power the car. Brake energy is also absorbed and stored in a battery to offer extra power during short acceleration occurrences.
To prevent leaks that could impair performance and safety, fuel cell generators, gas tanks, and distribution lines must be hermetically sealed and leak-checked by means of specific leak detectors. Vacuum technology and processes also play a key role here.
Future Trends for Green Technology in Vehicles
According to Bloomberg New Energy Finance, by 2040, more than half of all built and sold passenger cars will be electric. As public concern about climate change grows, governments throughout the world are stepping up efforts to reduce carbon emissions. Agilent is committed to supporting this change by providing the finest, more innovative and performing vacuum technology equipment and machinery.
