Title:
BATTERY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/179855
Kind Code:
A1
Abstract:
A disadvantage in a conventional technique is that, since current is uniformly suppressed simply according to temperature, short-time current that does not cause a temperature rise is also suppressed, which leads to the deterioration of fuel efficiency and the lowering of drivability in an electric vehicle. A battery control device is provided with a control unit for controlling the charging/discharging current of a storage battery, wherein said control unit estimates the temperature rise of the storage battery on the basis of a battery temperature and a charging/discharging current amount and controls the charging/discharging current by selecting, using the estimation result of the temperature rise, one upper limit charging/discharging current value from among a plurality of upper limit charging/discharging current values so as not to exceed the upper limit temperature of the storage battery.
