PURPOSE: To provide a small sized charger device with no changeover of large capacity required in a charger sharing a charger for a main battery and a charger for an accessory battery. CONSTITUTION: A charger 100 is mainly constituted of a primary side circuit 130, transformer T1, secondary side first output part 110, secondary side second output part 120 and a control circuit 15, to charge a main battery 20 and an accessory battery 21. The secondary side first output part 110 is constituted of a switching circuit 5 and a smoothing circuit 8, to constitute the switching circuit 5 of MOSFETs 55, 56. When the accessory battery 21 is charged with power of the main battery 20, the MOFETs 55, 56 are on/off operated to supply power to the transformer T1, and by the transformer T1, a secondary side winding M3 is induced to charge the accessory battery 21. |
