It is estimated that by 2020, the output of pure electric vehicles, hybrid cars and plug-in hybrids will account for 5% to 8% of the total car production. At present, car manufacturers are mainly focused on extending the mileage and reducing the cost of technology Attract ordinary drivers.
In June, the Swedish carmaker Volvo announced that all new models will be electricized from 2019, once again demonstrated the company's strong support for electric vehicles. Coincidentally, Tesla also released the first parity electric car Model 3 , The price of less than 40,000 US dollars, mileage is reached 200 miles.
"The demand for hybrid cars and electric vehicles is growing," said Lou Jianfeng, senior vice president of BASF's global business unit for battery materials. 'All carmakers, regardless of their size, are competing to reduce costs, increase mileage and ensure safety Sex, and extended life.
From battery materials to lightweight components that reduce energy consumption, BASF provides customers with a complete range of electric transportation solutions and helps automakers cope with these challenges through research and development.
Battery material
Optimize the battery material science, is to increase the electric car / hybrid mileage, extend the service life and reduce the cost of the fundamental way.
To this end, BASF has invested extensively in research and development to provide customers with a complete portfolio of materials and to build capacity in global strategic markets and to help customers address intellectual property issues through reasonable licensing, including collaboration with the US Department of Energy's Argonne National Laboratory Nickel-cobalt-manganese (NCM) composite cathode materials production and sales, and CAMX Power LLC reached a high-nickel patented patent CAM-7 patent licensing agreement.
'Advanced Materials Science is the key to meeting industry needs'
Reduce the use of expensive, rare reserves of cobalt, replaced by a lower cost, more abundant reserves of the elements, is the industry trends; increase the content of nickel and manganese is one of the ways in the early use of electric vehicles in the battery, Cobalt and other elements of the proportion is relatively balanced; but now the proportion of nickel has reached about 60%, and sometimes even up to 80%.
At the same time BASF also with the institutions, universities and partner companies, long-term investment, joint research and development for all solid-state batteries and protection of lithium negative system solutions.
"Advanced materials science is the key to meeting the needs of the industry, 'said Michael Fetcenko, Managing Director of BASF Battery Materials North America." These cathode materials have not been fully optimized, so BASF believes it is expected to address these challenges through incremental improvements and breakthroughs Electric vehicles and hybrid vehicles to meet the growing expectations of end users.With the rapid growth of the market, our global manufacturing and R & D network, as well as in the field of materials expertise, will become the basis of BASF disdain for the industry.
Characteristic material
As with the technical challenges of solving the battery material, reducing vehicle weight, reducing flammability, reducing arcing, using highly engineered materials to avoid physical and chemical aging of components, is also the key to achieving traffic electricization. The larger the battery, the stronger the battery life, but they will also increase the weight of the vehicle and provide higher requirements for thermal management. In the face of these challenges, BASF continues to expand its portfolio of plastic products to deliver innovative solutions of unique nature To meet the requirements of the next generation of battery technology. For example, the weight of a shell made with thermoplastics can be reduced by up to 30% compared to metal parts, and a one-line supplier can even lose 51% when using 35% glass-reinforced BASF Ultramid®. In addition, Ultramid® Thermoplastics can be used to produce battery frames thanks to excellent strength and high temperature performance, and these unique properties not only extend the life of the battery pack but also improve its performance.Using appropriate processing techniques, these materials Can provide excellent strength while reducing the weight of the end plate while maintaining the stability of the end plate. BASF continues to expand its portfolio of plastic products to meet the requirements of next-generation battery technology with innovative solutions of unique nature. Thermal conductive resin also reduces metal consumption and improves light weight. BASF offers customers an Ultramid® new antistatic material with good physical and mechanical properties, as well as other products with superior strength, stiffness and conductivity. The BASF material portfolio is also available for a wide range of high-voltage connectors, cables and charging infrastructures, both halogen-free and non-red-based flame retardants, as well as the only commercially available, Polybutylene terephthalate. In addition, BASF Ultramid Advanced N solution not only in high temperature environment with excellent physical properties, but also to withstand the test of corrosive media; due to very low moisture absorption, the product can also be wet Keep the size stable in the environment. The use of thermosetting polymers for the production of the Parmete® flexible perforated foam provides an ideal lightweight solution for electrification applications with excellent high temperature resistance and flame retardancy that protects engine components and can not withstand long periods of time High temperature of the surrounding parts to provide protection. "Car manufacturers wanting to build electrification products need to use engineering plastics solutions to provide high-temperature protection for precision components and reduce vehicle weight," said Dalia Naamani-Goldman, North American Electric Traffic Industry Manager, BASF Materials Division. 'The lighter weight, Battery life is stronger; and a single charge mileage is one of the most important distinguishing factors, so this is very important to the market. Reduce noise In addition to reducing or even eliminate emissions, the quiet, smooth driving experience is undoubtedly one of the most attractive advantages of electric vehicles. But many people do not realize that noise, vibration and roughness (NVH) to the engineers have brought many challenges.Although the electric car without the traditional internal combustion engine noise, but engineers must redefine and optimize the car sound, comfort And experience, without affecting the driving efficiency of the vehicle. BASF's NVH solution helps to meet this challenge, and BASF can help manufacturers design innovative solutions to optimize acoustic comfort, vehicle power performance and safety, using sound insulation that can significantly reduce high-frequency noise. An engine mount made with Cellasto® microcellular polyurethane elastomer is one example that effectively blocks and absorbs high frequency noise from electromagnetic pulses and torque pulses. In addition, the Cellasto electric engine bracket also helps to reduce weight and keep the car's sound level and quality, and preliminary tests show that carmakers can reduce component weight by up to 30 percent when using Cellasto. Reduce energy consumption of HVAC But these systems energy consumption amazing, up to the battery mileage will be reduced by 40% - 50%. In the hottest and coldest season of the year, many drivers will turn on heating, ventilation and air conditioning systems to improve comfort. In order to reduce the impact of sunlight and reduce the energy consumption of the car, BASF has developed a series of cool pigments to help control the car Temperature. Some of these dark pigments can even absorb up to 90% of the sun's heat. BASF carbon black pigment can reflect the incident sunlight, reduce the absorption rate, which will reduce the surface temperature of 15-20 degrees Celsius. 
The BASF catalyst sector is also active in reducing the impact of the heating and cooling system on the battery while using the cool pigments to help OEMs keep the car surface cool.Using advanced HVAC technology, the BASF solution can improve recycling efficiency and prevent Moisture and carbon dioxide into the car, up to 10% of the mileage of electric vehicles.
'BASF realizes that car manufacturers and suppliers are actively developing strategies to address the challenges associated with electrification and will continue to play a wealth of expertise in chemistry and materials to help customers go further.' Lou Jianfeng said The
