Abstract
An electricity storage system includes a plurality of chargeable and dischargeable battery boards, a plurality of PCSs connected to the respective battery boards, and charging and discharging the connected batteries, and a battery controller distributing a charging and discharging power value of the entire system as an instruction value to each of the PCSs at a constant cycle or at an arbitrary timing. The battery controller gives a charging and discharging instruction for a predefined test charging and discharging to the selected battery board, and distributes, to all the battery boards except the selected battery board, a value obtained by subtracting a charging and discharging power value for the test charging and discharging from a charging and discharging power value for the entire system.
