The invention relates to a lithium battery pack management system. The lithium battery pack management system comprises N sets of lithium batteries, N slave control panel cards, a main control board 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 can be performed on the single battery with a large state difference according to the 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 board can give an SOC estimated value, provides a charging and discharging management strategy, and extends the service lifetime of the battery. The host computer displays the collected state information, control information, abnormality information and alarm information of a lithium battery pack and provides friendly man-computer interaction. Meanwhile, a similar modularization design scheme is brought forward for hardware development of the system, and the maintenance cost can be effectively reduced.
