Electric vehicles use batteries to provide energy for their operation. In order to ensure the long-distance driving of electric vehicles, to meet the user's needs, it is usually necessary to set up multiple batteries to ensure the electric energy supply of electric vehicles in the long-distance driving process.
However, in the long-distance driving process of electric vehicles, the temperature of the battery rises sharply. Moreover, the more batteries are carried, the higher the temperature of the battery pack is particularly serious. If the battery works at a high temperature, its working life will be greatly reduced, at the same time, it will affect the reliability and working performance of the electric vehicle. If the internal heat of the battery system is not effectively controlled, it will cause the heat of the battery out of control. If the temperature of the battery is too high, the cycle life of the battery will be reduced. At the same time, the battery will also heat up in the process of charging and discharging, and there is a risk of fire.
In addition, the temperature difference between the cells will also reduce the battery consistency. Therefore, the battery cooling system is very important to ensure the battery life, safety and consistency. Behind the "hot" electric vehicle, the battery cooling system is needed to "cool down". For the battery, the overheated temperature is too high, the consequences are incalculable, the lighter temperature is too high, which affects the performance of the battery. In serious cases, if the heat is not emitted, there will be a hidden danger of spontaneous combustion. The heat dissipation of the electric vehicle motor and battery is also necessary.
At 20:00-21:00 on March 30, general manager Luan Huanguang of Zhongshan Kebang Chemical Material Technology Co., Ltd. will introduce to you the basic mechanism of thermal runaway of electric vehicle battery and the heat spread caused by it in the "Beijing New Material Association" online classroom of Beijing New Material Technology Association; the mechanism of STM coating; the application of STM coating on electric vehicle battery to extend the time of thermal spread caused by thermal runaway, So as to improve the safety performance.
