Title:
BATTERY MANAGEMENT SYSTEM AND ITS DRIVE METHOD
Document Type and Number:
Japanese Patent JP2010011721
Kind Code:
A
Abstract:
To provide a battery management system and its actuating method capable of controlling a time point to measure the cell voltage and the current of the battery.
The battery management system has a sensing unit and an MCU. The sensing unit holds a detecting voltage corresponding to the cell voltage of a first battery in a plurality of battery cells, and measures the current of the battery at the time point when the detecting voltage has been stored. The MCU controls the sensing unit to measure the current of the battery at the time point when the storage of the detecting voltage has been completed.
