MANAGEMENT DEVICE, CHARGING AND DISCHARGING CONTROL DEVICE, ELECTRICITY STORAGE SYSTEM, AND CHARGING AND DISCHARGING CONTROL METHOD

摘要

A control unit gives an instruction of a charging and discharging control for discharging an electricity storage device down to a second target SOC after charging the electricity storage device up to a first target SOC. As a predicted temperature during the next charging and discharging cycle of the electricity storage device increases, the control unit reduces the first target SOC and the second target SOC. When reducing the first target SOC and the second target SOC, the control unit gives an instruction of a charging and discharging control for more reducing the second target SOC in comparison with the first target SOC.
