Document Type and Number:
WIPO Patent Application WO/2011/105083
Kind Code:
A1
Abstract:
A battery control apparatus is connected to a plurality of battery cells. The battery control apparatus comprises a voltage calculation unit, a communication unit, and a voltage update unit. The voltage calculation unit calculates the voltages of each of the battery cells on the basis of currents flowing into the plurality of battery cells. When the battery control apparatus is connected to a charge control apparatus, the communication unit receives, from the charge control apparatus, information pertaining to the voltages of each of the battery cells detected by the voltage detection unit of the charge control apparatus. The voltage update unit updates the voltages calculated by the voltage calculation unit on the basis of voltage information received by the communication unit.
