CONTROLLER, CONTROLLER NETWORK AND CONTROL METHOD

摘要

A controller, a controller network and a method for controlling a charging/discharging that easily make SOC of secondary batteries close to a target value are provided. An ordering index including difference ”SOCm=SOCt-SOCm between the target value SOCt of SOC (state of charge) and a calculated value SOCm of SOC as a main factor is reflected to an order of charging priority and an order of discharging priority of NaS battery. In addition, charging power is allocated to secondary batteries in descending manner of order of discharging priority and discharging power is allocated to the secondary batteries in descending manner of order of discharging priority.
