Battery management system and method

A battery management system is provided. A voltage of a first battery cell is charged to a capacitor. Then, the voltage of the capacitor is measured, the measured voltage being the voltage of the first battery cell. Subsequently, a voltage of a second battery cell is again charged to the capacitor w...

Beschreibung
Zusammenfassung:	A battery management system is provided. A voltage of a first battery cell is charged to a capacitor. Then, the voltage of the capacitor is measured, the measured voltage being the voltage of the first battery cell. Subsequently, a voltage of a second battery cell is again charged to the capacitor while the capacitor holds the voltage of the first battery cell. The voltage of the capacitor is then measured, the measured voltage being the voltage of the second battery cell. With such a scheme, the time for discharging the capacitor may be removed, and accordingly, a period for measuring a voltage of the battery cell may become shorter.
