The temperature of a battery is one of the key factors in its performance and lifespan. High temperatures can cause the battery to overheat, reducing its performance and accelerating life loss, while low temperatures can reduce the battery's energy density and power output. The battery thermal management system
monitors the temperature of the battery by installing temperature sensors to ensure that it works within a safe range. When the battery temperature approaches or reaches dangerous levels, the system takes steps to control the temperature, such as reducing the charging rate or activating the cooling system. Its functions cover many aspects such as temperature monitoring, heat dissipation, heat dissipation, and charging control.
