How to manage the temperature of the power battery in pure electric vehicles

The power battery of pure electric vehicles is temperature controlled through a temperature management system. The temperature management of power batteries is an important factor in ensuring battery performance and lifespan, as the performance and lifespan of batteries are greatly affected by temperature. The power battery temperature management system of pure electric vehicles usually includes the following aspects: 1 Heat dissipation system: The heat generated inside the battery is dissipated through the heat dissipation system to maintain the temperature of the battery within an appropriate range. The cooling system usually includes components such as fans, heat sinks, and heat pipes. 2. Heating system: In low-temperature environments, the performance of power batteries will be affected, so a heating system is needed to heat the battery to increase its temperature. Heating systems typically include components such as electric heaters and liquid heaters. 3. Temperature sensor: Real time monitoring of the battery is carried out through the temperature sensor to ensure that the temperature of the battery is within the appropriate range. Temperature sensors are usually installed inside the battery pack or on the surface of the battery pack. 4. Control system: Control the heat dissipation system and heating system through the control system to ensure that the temperature of the battery is within an appropriate range. The control system is usually completed by a Battery Management System (BMS), which controls the temperature management system based on the actual temperature and working status of the battery. In summary, the temperature management of the power battery in pure electric vehicles is controlled through components such as the cooling system, heating system, temperature sensors, and control system. Through reasonable temperature management, the performance and lifespan of batteries can be improved, ensuring their safety and reliability.
