The electric auxiliary vehicle (10, 20) includes batteries (BT1∼BTn), a motor (MT), and power receiving ports (P1∼Pn). The power management circuit (100, 200) includes a transformer (TR), an inductor (LB), primary circuits (110_1∼110_n, 210_1~210_n), a motor driving circuit (120, 220), and charging-and-discharging circuits (130_1∼130_n, 230_1∼230_n). The transformer (TR) includes primary windings (LP1∼LPn) and a secondary winding (LS). The inductor (LB) is coupled in parallel with the secondary winding (LS). Each primary circuit (110_1∼110_n, 210_1~210_n) provides wireless power (VWPT1∼VWPTn) from a power receiving port (P1∼Pn) to a primary winding (LP1∼LPn) at different time periods, and provides electric energy from the primary winding (LP1∼LPn) to the power receiving port (P1∼Pn) at different time periods. Each charging-and-discharging circuit (130_1∼130_n, 230_1∼230_n) provides electric energy from the inductor (LB) to a battery (BT1∼BTn) at different time periods, and provides battery electric energy (PB1∼PBn) from the battery (BT1∼BTn) to the inductor (LB) at different time periods.
