  "textContent": "The present invention provides a battery heating circuit, comprising a plurality of switch units (1), a switching control module (100), a damping element R1, an energy storage circuit, and a polarity inversion unit (101), wherein, the energy storage circuit is connected with the battery, and comprises a current storage element L1 and a plurality of charge storage elements C1; the plurality of charge storage elements C1 are connected with the plurality of switch units (1) in series in one-to-one correspondence to form a plurality of branches; the plurality of branches are connected in parallel with each other and then connected with the current storage element L1 and damping element R1 in series; the switching control module (100) is connected with the switch units (1), and is configured to control ON/OFF of the switch units (1), so that the energy flows to and fro between the battery and the energy storage circuit when the switch units (1) switch on; the polarity inversion unit (101) is connected with the energy storage circuit, and is configured to invert the voltage polarity of the plurality of charge storage elements C1 after the switch units (1) switch from ON state to OFF state. The heating circuit provided in the present invention can improve charge/discharge performance of the battery, as well as safety and work efficiency in the battery heating process.",
