Title:
BATTERY CONTROL DEVICE, BATTERY SYSTEM, ELECTRIC VEHICLE, MOBILE BODY, ELECTRIC POWER STORAGE DEVICE, AND POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/111350
Kind Code:
A1
Abstract:
Each battery module is provided with a range determination unit and a voltage detection unit. The range determination unit is connected through transmission lines to a battery. The voltage detection unit is connected through communication lines to the battery. In the battery, using the voltage range determination result of each battery cell determined by the range determination unit, a voltage calculation unit calculates the terminal voltage of the each battery cell. A control value calculation unit then calculates a battery control value by using either the terminal voltage of the each battery cell detected by the voltage detection unit or the terminal voltage of the each battery cell calculated by the voltage calculation unit.
