Title:
POWER STORAGE SYSTEM, CONTROLLER, AND STORAGE BATTERY CHARGING AND DISCHARGING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/002292
Kind Code:
A1
Abstract:
Provided is a power storage system comprising: a power storage unit which includes one or more storage batteries; a storage unit which stores history information of the power storage unit; and a control unit. The control unit acquires the history information from the storage unit. When the set charging voltage value of the power storage unit is set to a normal charging voltage value, and if the history information satisfies a voltage change condition, the control unit performs control to: change the set charging voltage value of the power storage unit to a low charging voltage value which is lower than the normal charging voltage value; and restore, after the power storage unit performs charging/discharging at the low charging voltage value, the set charging voltage value of the power storage unit to the normal charging voltage value.
