Preventing battery overheating: Excessive temperature can accelerate chemical reactions inside the battery, leading to capacity degradation and shortened lifespan. The heat exchanger indirectly prevents the battery from overheating during charging by cooling the charging pile. For example, when the ambient temperature is high or fast charging is performed, the heat generated by the charging pile is relatively high. The heat exchanger can effectively reduce the temperature of the charging current and voltage, reduce the heat conducted to the battery, and keep the battery charging within the appropriate temperature range, thereby extending the battery life.

Reduce the loss of chemical substances inside the battery: Excessive temperature can cause the electrolyte inside the battery to evaporate, electrode materials to age, and reduce the performance and lifespan of the battery. The heat exchanger controls the temperature of the charging environment, which helps to slow down the rate of chemical loss inside the battery, maintain the chemical balance inside the battery, extend the cycle life of the battery, and reduce the cost and frequency of battery replacement due to premature aging.
