Abstract
A charging/discharging control apparatus includes a motor, an electric drive circuit, a source voltage sampling circuit, a charging/discharging current sampling circuit, and a control chip, where the control chip is configured to send a first pulse width modulation (PWM) drive signal to the electric drive circuit, and the first PWM drive signal instructing the electric drive circuit to store electric energy of an external power supply in an inductor of the motor and charge a battery using the electric energy stored in the inductor of the motor.
