Title:
電池制御装置
Document Type and Number:
Japanese Patent JP7056113
Kind Code:
B2
Abstract:
The battery control unit includes a voltage detection unit detecting voltage at the battery cell where noise is eliminated by the filter circuit, the voltage being detected immediately before/after a discharging is performed through the discharge circuit; a correction value calculation unit that calculates an amount of a voltage drop at the connection member when a discharging is performed through the discharge circuit, to be a correction value; and a voltage calculation unit that calculates voltage of the battery cell by adding the correction value calculated by the correction value calculation unit to a post-discharge voltage detected immediately after the discharging by the voltage detection unit.
