The outstanding of this study is: for system hardware design, a new voltage measuring circuit, which is used to measure the voltage of the individual battery of batteries is designed; for the functions of the new instrument, it is used to monitor the battery on-linely and real-timely not only when the battery is on floating charging but also on the course of charging and discharging with the new judging criterion of battery performance. Even more, the battery, which is good in floating charging and actually may be bad, could be found quickly by discharging for a short time periodically. The precision, automation and intelligence of the monitoring system for battery is improved greatly.
