이차 전지와 급속 충방전 축전 디바이스를 구비하는 축전 시스템에 있어서, 이차 전지의 파워 밀도가 7000W/kg 미만, 급속 충방전 축전 디바이스의 파워 밀도가 7000W/kg 이상인 것을 특징으로 한다. 또한, 급속 충방전 축전 디바이스의 파워 밀도가 9000W/kg 이상인 것이 바람직하다. 또한, 이차 전지의 에너지 밀도가 30Wh/kg 이상인 것이 바람직하다.

    An electricity storage system which is equipped with a secondary battery and a high-rate charge/discharge electricity storage device, and which is characterized in that the secondary battery has a power density of less than 7,000 W/kg and the high-rate charge/discharge electricity storage device has a power density of 7,000 W/kg or more. It is preferable that the high-rate charge/discharge electricity storage device has a power density of 9,000 W/kg or more. It is also preferable that the secondary battery has an energy density of 30 Wh/kg.
