Battery exchange station and method of operating battery exchange station
First Claim
1. A battery exchange station connected to an electric power system, the station comprising:
- a plurality of batteries including a large-capacity battery used only for electric power storage and a replacement battery that is interchangeable with a battery of a vehicle; and
a controller programmed to control charging and discharging of the batteries, including controlling the station to charge the batteries with electricity supplied from the system and controlling the station to discharge the electricity stored in the batteries to the system based on an operation status of the system; and
wherein, after determining the operation status of the system, the controller supplies the electricity stored in the batteries to the system if the system is operating at peak time during which the load power consumption of the system is at its peak, and supplies the electricity from the system to the batteries if the system is operating at off-peak time, wherein the peak time is set by dividing the time spent by the system on consuming the load power into several periods and specifying and period during which the load power consumption of the system is at its peak.

Abstract
A battery exchange station and a method of operating the battery exchange station are provided which can solve conventional problems, such as the unavailability of electricity stored in a battery, the difficulties in coping with changes in system operation, and the difficulties in utilizing renewable energy. The battery exchange station and the method of operating the battery exchange station allow for utilization of electricity stored in a battery and improve a system'"'"'s operation and electricity demand conditions by charging a large-capacity battery with electricity coming from the system and providing the electricity stored in the large-capacity battery to the system.
