SECONDARY BATTERY POWER CONTROL METHOD
First Claim
1. A method of controlling power discharged from a secondary battery that is included in an interconnected system, the interconnected system supplying power to a power system, and including a power generator that changes in output power, and an electric power storage-compensation device that includes the secondary battery, and a bidirectional converter that controls charging/discharging of the secondary battery, the electric power storage-compensation device compensating for a change in output power of the power generator,a temperature detection section that detects a temperature of the secondary battery being annexed to the secondary battery,the method comprising limiting maximum discharge power of the secondary battery using the bidirectional converter when the temperature of the secondary battery detected by the temperature detection section has exceeded a preset temperature.

Abstract
A secondary battery power control method controls power discharged from a secondary battery included in an interconnected system that supplies power to a power system, the interconnected system including a power generator that changes in output power, and an electric power storage-compensation device that includes a secondary battery, and a bidirectional converter that controls charging/discharging of the secondary battery, and compensates for a change in output power of the power generator. A temperature detection section that detects the temperature of the secondary battery is annexed to the secondary battery, and the maximum discharge power of the secondary battery is limited using the bidirectional converter when the temperature of the secondary battery detected by the temperature detection section has exceeded a preset temperature.
