Abstract: The present invention provides a battery heating circuit, comprising a switch unit (10), a switching control module (100), a one-way semiconductor element D10, a damping element R, and a transformer (T), wherein, the switching control module (100) is electrically connected with the switch unit (10); the battery, damping element R, first winding of the transformer (T), and switch unit (10) are connected in series with each other to constitute a battery discharging circuit; the battery, damping element R, second winding of the transformer (T), and one-way semiconductor element D10 are connected in series with each other to constitute a battery charging circuit. The transformer in the present invention serves as an energy storage element, and has current limiting function. The present invention not only can limit the magnitude of current in the battery charging/discharging circuit, thereby the battery and switch unit can be protected against damage by heavy current, but also can reduce the energy loss in the heating process.
