CHARGING AND DISCHARGING CONTROL METHOD, CHARGING AND DISCHARGING CONTROL SYSTEM AND CHARGING AND DISCHARGING CONTROL DEVICE

摘要

A charge or discharge control method includes: receiving a power instruction value with respect to a power storage apparatus (S001); obtaining a remaining state of charge (SOC) and a target SOC which is a target value of the SOC of the power storage apparatus (S002); controlling charge or discharge of the power storage apparatus according to the power instruction value when the power instruction value is received; wherein, in the controlling, a delay time is determined according to a difference between the target SOC and the remaining SOC, and the power storage apparatus is controlled according to the power instruction value at a timing when the delay time passes after the power instruction value is received (S003, S004).
