METHOD FOR RESTORING SECONDARY BATTERY, SYSTEM FOR RESTORING SECONDARY BATTERY AND VEHICLE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2011/132300
Kind Code:
A1
Abstract:
Disclosed is a method for restoring a secondary battery which can restore the charge/discharge capacity of a used secondary battery. The state of charge (SOC) of the battery to be restored is acquired; if the acquired SOC is within an already determined range, the acquired SOC is taken as the storage SOC; if the acquired SOC is outside of the already determined range, the secondary battery is charged and discharged until within range, and the SOC after charging and discharging is taken as the storage SOC; a restoration map with the relationship between storage SOC, storage temperature, storage period, and target restoration rate stored therein is used to determine a storage period which will allow restoration of the secondary battery charge/discharge capacity to the target restoration rate through storage at the storage temperature and storage SOC; and the secondary battery is stored for the determined storage period while the storage temperature and storage SOC are maintained.
