Title:
BATTERY-CAPACITY MANAGEMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/008462
Kind Code:
A1
Abstract:
A battery-capacity management device for a storage battery included in a vehicle having an electric motor as a driving source comprises: a degradation state estimation unit for estimating the degradation states of the storage battery; region setting unit for setting, according to the degradation states of the storage battery, a battery capacity within which the storage battery can be used to a plurality of regions; a state-of-charge derivation unit for deriving a state of charge of the storage battery; a region determination unit for determining, among the plurality of regions set by the region setting unit, which regions the state of charge of the storage battery belongs to; and a control instruction unit for instructing to control the charging and discharging of the storage battery according to the region determined by the region determination unit. Among the plurality of regions set by the region setting unit, the battery capacity range of at least one predetermined region is constant regardless of the degradation states of the storage battery, and the battery capacity ranges of the regions other than the predetermined region are different depending on the degradation states of the storage battery. Accordingly, the effect of the degradation is minimized and the performance of the storage battery can be exerted sufficiently.
