This application provides a charge/discharge circuit, a charge/discharge system, and a charge/discharge control method. The charge/discharge circuit includes a power supply module, a switch module, an energy storage module, and a charge-discharge switching module. The switch module, the charge-discharge switching module, and the power supply module are connected in parallel. A first terminal of the energy storage module is connected to the switch module, and a second terminal of the energy storage module is connected to the charge-discharge switching module. The switch module and the charge-discharge switching module are configured to perform an action in response to a charge/discharge enable signal to produce an alternating current in the charge/discharge circuit. In the charge/discharge circuit of this application, the switch module and the charge-discharge switching module of the charge/discharge circuit can perform an action in response to the charge/discharge enable signal to produce an alternating current in the charge/discharge circuit, such that the alternating current produces heat in the power supply module, thereby heating the power supply module. This can effectively suppress noise caused by motor vibration and resolve the problem that the motor vibrates so much as to produce excessive noise during the heating in conventional traction battery heating technologies which use a motor loop to heat the traction battery.
