BATTERY HEATING CIRCUIT

摘要

A battery heating circuit is provided, which comprises a switch unit (1), a switching control module (100), a damping element R1 and an energy storage circuit. The energy storage circuit is connected with the battery and comprises a current storage element L1 and a charge storage element C1. The damping element R1, the switch unit (1), the current storage element L1 and the charge storage element C1 are connected in series. The switching control module (100) is connected with the switch unit (1) and is designed to control ON/OFF of the switch unit (1), so as to control the energy flowing between the battery and the energy storage circuit. The heating circuit can improve the charge/discharge performance of the battery, improve safety when the battery is heated and effectively protect the battery.
