Due to favorable factors such as the auto industry's trade-in policy, local replacement subsidies and the intensive delivery of new models, the sales volume of new energy vehicles in China is booming. It is reported that the cumulative penetration rate of China's new energy vehicles reached in the first 10 months of this year, and the penetration rate of new energy vehicles from July to October was above 52%. By November 14, the annual output of China's new energy vehicles exceeded 10 million for the first time.

Safety, lightweight and reliability are the key focus of new energy vehicle development, which are inseparable from battery pack. Battery pack the shell mass accounts for 2% ~ 6% of the whole vehicle. It not only needs to accommodate high-voltage batteries, electronic components, sensors, connectors and other core electronic components, but also has good comprehensive performance. At high temperature, wading, even under extreme conditions such as impact, ensure the safety and stability of the battery to the greatest extent. With the development of lightweight automobile and the development of thermosetting plastic molding technology, new plastics and composite materials are gradually used as shell materials for battery pack.

In terms of thermal management system, since new energy vehicles generate heat from batteries and motors during work, therefore, the temperature control of the thermal management system is more accurate and complex-it not only needs to keep the battery warm but also needs to heat it; The temperature of the motor should not be too high, at the same time, necessary heat dissipation measures need to be taken. Relevant application fields have put forward high requirements for the chemical corrosion resistance, oil resistance, mechanical properties, heat resistance, thermal stability, flame retardant, processability, dimensional stability and so on of plastic materials.

Although plastic materials are promising in the battery and thermal management system of new energy vehicles, petroleum-based plastics not only have high carbon emissions, but also have high costs. Thermosetting plastics are limited in automobile exports because they cannot be recycled. So, what material solutions in the market can not only solve the above two problems, but also meet the requirements of easier processing, lower carbon and more sustainable?

Kesai creatures have something to say! As the innovator and pioneer of global bio-manufacturing, the core raw materials of bio-based polyamides and their full series of material solutions launched by Kaisai biology are new polymer materials derived from renewable resources, which are green, environmentally friendly, the raw materials are renewable and recyclable. At the same time, they have the main advantages of high strength, high rigidity, good temperature resistance, excellent fatigue strength, good self-lubricating performance, excellent processing performance, etc, it is very suitable for the choice of high-performance New materials as auto parts. Not only that, the bio-based polyamide material of Kaisai biology can reduce carbon by at least 50%, and its thermoplastic continuous fiber reinforced bio-based polyamide composite material supports recycling, helps reduce carbon emissions throughout the product life cycle from production to application.

Speaking of which, can you wait to learn more about the battery pack lightweight solutions and thermal management solutions of Kaisai creatures? At 14:00-15:00 on December 18, Wang Xinxin and Wang Xiao, heads of new energy products of Shanghai Kaisai Biotechnology Co., Ltd, will be guests in Jung's online class, unveils the mystery of high-performance bio-based composite materials and bio-based polyamide materials, and opens the green and lightweight era of innovative cars with you!
