BATTERY HEATING CIRCUIT, BATTERY HEATING SYSTEM, AND BATTERY ASSEMBLY

A battery heating circuit, a battery heating system, and a battery assembly are provided. The battery heating circuit included an inductor module, a capacitor module, a first switch module, a second switch module, and a battery heating module. A control terminal of the first switch module is configured to receive a first switch control signal. A control terminal of the second switch module is configured to receive a second switch control signal. The first switch control signal or the second switch control signal is a pulse signal. Heating input power of the battery heating module is controlled through the pulse signal and energy storage in the inductor module and the capacitor module, such that a power-controllable battery heating method may be implemented.
