Abstract:
1. A power supply system for supplying electric power to first and second load devices, comprising: a first electric power line pair electrically connected to said first load device; a plurality of rechargeable power storage units a plurality of voltage conversion units arranged corresponding to said plurality of power storage units respectively, said plurality of voltage conversion units being connected in parallel to said first electric power line pair and each being configured to perform a voltage conversion operation between said first electric power line pair and corresponding said power storage unit; a plurality of disconnection units arranged corresponding to said plurality of power storage units respectively, each for electrically disconnecting corresponding said power storage unit and corresponding said voltage conversion unit from each other; a second electric power line pair having one end electrically connected between a first voltage conversion unit representing one of said plurality of voltage conversion units and corresponding said disconnection unit and another end electrically connected to said second load device; and a control unit for controlling said plurality of voltage conversion units, when one disconnection unit among said plurality of disconnection units electrically disconnects corresponding said power storage unit and corresponding said voltage conversion unit from each other, such that electric power supply to said first load device and electric power supply to said second load device are continued through said first electric power line pair and through said second electric power line pair respectively by using electric power from remaining said power storage unit.
