MANAGEMENT APPARATUS FOR ENERGY STORAGE DEVICE, ENERGY STORAGE APPARATUS, AND INPUT/OUTPUT CONTROL METHOD FOR ENERGY STORAGE DEVICE

The present invention comprises a voltage detection circuit for measuring the voltage of an assembled battery in which power storage elements are serially connected, a current detection resistor for detecting the current in the assembled battery and a CPU for calculating, inter alia, the amount of energization electricity from continuous charging or continuous discharging of the assembled battery The CPU controls input/output for when the assembled battery is charged/discharged so that ΔSOC, which is the value obtained by dividing the amount of energization electricity by the actual capacity of the assembled battery does not exceed an upper limit ΔSOC.
