Their optimal operating temperature, however, is between 15°C and 35°C, the range where they perform the best. To maximize the performance and longevity of the battery pack, it is essential to maintain a uniform temperature distribution across all battery cells. Ideally, the maximum surface temperature variation is no more than 5°C.
The battery temperature sensor is a critical component in battery management systems (BMS) that measures the temperature of the battery to ensure safe and efficient operation. The temperature of the battery is a key performance indicator and can significantly affect the battery''s life, capacity, and performance.
