Power supply device for supplying electricity to a load utilizing electric power of a storage-battery-equipped vehicle
First Claim
1. A power supply device comprising:
- a plurality of vehicle connecting portions connected in a one-to-one relationship with a plurality of storage-battery-equipped vehicles;
a load connecting portion connected to a load;
a power supply portion for performing a charge operation to charge storage batteries of the storage-battery-equipped vehicles and a discharge operation to discharge the storage batteries, during which the load is supplied with electricity;
a memory portion for storing the number of charges and discharges for each of the storage-battery-equipped vehicles; and
a supply control portion for selecting a supply vehicle to serve as a power source from among the storage-battery-equipped vehicles at predetermined time intervals, whereby the power supply portion performs the discharge operation only on the supply vehicle, wherein,the supply control portion selects as the supply vehicle one of the storage-battery-equipped vehicles that satisfies a first condition that a state of charge (SOC) of the storage battery is greater than or equal to a prescribed value and a second condition that the number of charges and discharges is not the highest among the storage-battery-equipped vehicles,wherein the supply control portion selects as the supply vehicle one of the storage-battery-equipped vehicles that satisfies, in addition to the first and second conditions, a third condition that a connection to the vehicle connecting portion has a temperature lower than a preset temperature,wherein the supply control portion determines whether the first, second, and third conditions are satisfied, in a predetermined order for the storage-battery-equipped vehicles, and thereby sets as the supply vehicle the first vehicle that is determined to satisfy the first, second, and third conditions, andwherein only one vehicle is selected as the supply vehicle.

Abstract
A power supply device including vehicle connecting portions, a load connecting portion, a power supply portion, a memory portion for storing the number of charges and discharges for each storage-battery-equipped vehicle, and a supply control portion for performing control such that the power supply portion performs a discharge operation only on a selected supply vehicle. The supply control portion selects as the supply vehicle one of the storage-battery-equipped vehicles that satisfies a first condition that an SOC of a storage battery is greater than or equal to a prescribed value and a second condition that the number of charges and discharges is not the highest among the storage-battery-equipped vehicles.
