Lithium battery set management system

The utility model relates to a lithium battery set management system comprising N sets of lithium batteries, N slave control panel cards, a main control panel card and a host computer. The system can monitor the voltage, the charging and discharging currents, the operating temperature and the environmental temperature of a single lithium battery in real time, equalization control of the single battery with a large state difference can be performed according to detected voltage of the lithium battery and an equalization algorithm brought forward, and the consistency of the battery is improved. According to collected parameters, the main control panel card can give an SOC estimated value, provide a charging and discharging management strategy, and extend the service lifetime of the battery. The host computer display the collected state information, control information, abnormal information and alarm information of the lithium battery set, and provide friendly human-computer interaction. Meanwhile, the lithium battery set management system develops and brings forward a modularization design proposal of hardware of the system and can effectively reduce the maintenance cost.
