<P>PROBLEM TO BE SOLVED: To provide an on-vehicle power supply apparatus and a power supply system capable of efficiently charging a stationary battery from an on-vehicle power supply neither too much nor too little. <P>SOLUTION: A power supply system 1 includes: a stationary power supply apparatus 2 (stationary machine) for home use; and an on-vehicle power supply apparatus 3 (on-vehicle machine) mounted on a vehicle. The on-vehicle machine 3 includes: a rotary electric machine 32 (generator) driven by an engine 31; an on-vehicle battery 35 for drive that constitutes a hybrid vehicle driving system; and a relief battery 38. A stationary battery 23 disposed on the stationary machine 2 is charged by any one of the rotary electric machine 23, the stationary battery 35, or the relief battery 38 via an inter-battery transmission route 40 in DC current. The amount of charging to the stationary battery 32 is determined according to the electric energy WRQ required by the stationary machine 2 and the electric energy WVH for which the on-vehicle machine 3 can supply. Hence, the system can efficiently charge the stationary battery 23 from a plurality of the on-vehicle power supplies 32, 35, and 38 neither too much nor too little. <P>COPYRIGHT: (C)2013,JPO&INPIT |
