POWER DISTRIBUTION SYSTEM, METHOD FOR CHARGING ACCUMULATOR BATTERY FOR TRAVELING OF ELECTRIC VEHICLE USING THE POWER DISTRIBUTION SYSTEM AND METHOD FOR FEEDING POWER FROM ACCUMULATOR BATTERY FOR TRAVELING OF ELECTRIC VEHICLE TO THE POWER DISTRIBUTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a power distribution system and the like in which a generation source of power to charge an accumulator battery for traveling of an electric vehicle can be distinguished.SOLUTION: A power distribution system 10 comprises a first power distribution system 14 for supplying power generated by a centralized power source and power generated by a distributed power source to electric facilities. The power distribution system 10 further comprises: a second power distribution system 16 which is provided electrically independently from the first power distribution system and distributes power only from the distributed power source; switching means 22 for selectively switching power distribution from the distributed power source to the first power distribution system 14 or the second power distribution system 16; a charging device 40 which is provided in the second power distribution system 16 and is capable of charging an accumulator battery 20 for traveling of an electric vehicle 2 with power generated by the distributed power source; and charging amount detection means 44 for detecting the amount of power with which the accumulator battery 20 for traveling of the electric vehicle 2 is charged by the charging device 40.
