Disclosed is a power management circuit for an electric auxiliary vehicle. The electric auxiliary vehicle includes a battery, a motor, and a power receiving terminal. The power management circuit includes a transformer, a primary circuit, first and second power transmission circuits, and a controller. The transformer includes primary and secondary windings. The primary circuit is connected to the primary winding and the power receiving terminal. The first power transmission circuit is connected to the secondary winding and the battery. The second power transmission circuit is connected to the secondary winding, battery, and motor. The controller controls the primary circuit and the first power transmission circuit to provide battery power of the battery to the power receiving terminal in a first operating mode. The controller controls the second power transmission circuit in a second operating mode, so that the second power transmission circuit uses power of motor to charge the battery.
