A power management circuit for an electric auxiliary vehicle is provided. The electric auxiliary vehicle includes batteries, a motor, and power receiving ports. The power management circuit includes a transformer, an inductor, primary circuits, a motor driving circuit, and charging-and-discharging circuits. The transformer includes primary windings and a secondary winding. The inductor is coupled in parallel with the secondary winding. Each of the primary circuits provides wireless power from a corresponding power receiving port to a corresponding primary winding at different time periods, and provides electric energy from the corresponding primary winding to the corresponding power receiving port at different time periods. Each of the charging-and-discharging circuits provides electric energy from the inductor to a corresponding battery at different time periods, and provides battery electric energy from the corresponding battery to the inductor at different time periods.
