<P>PROBLEM TO BE SOLVED: To provide a power storage system controller for a cable wire auxiliary power supply wherein when a vehicle is at a stop, power supplied to load equipment in the vehicle is stored in a battery, and when the vehicle is in travel, power can be continuously supplied to the load equipment in the vehicle as auxiliary power supply for interior lights, a heater and the like without supplying power from a trolley wire through a pantograph. <P>SOLUTION: A trolley wire 1 is connected to an AC-DC conversion unit 3 through a pantograph 2. A DC-AC conversion unit 5 connected in parallel with a battery 4 connected to its direct-current portion is connected with in-vehicle load equipment 6. Therefore, the following can be implemented even if the battery 4 has been charged and the pantograph 2 is disconnected from the trolley wire 1: power can be continuously supplied to the in-vehicle load equipment 6 through the DC-AC conversion unit 5 using the power charged in the battery 4. <P>COPYRIGHT: (C)2008,JPO&INPIT |
