英文摘要The invention relates to an intelligent power lithium ion battery management system. The system comprises a microcontroller module, an acquisition module, a storage module, a safety protection module, a communication module, a charging and discharging control module and an equalization management module, wherein the acquisition module, the storage module, the safety protection module, the communication module, the charging and discharging control module and the equalization management module are connected to the microcontroller module. The charging method comprises the following steps that according to a single battery voltage collected by the acquisition module, a total voltage of a battery pack, a temperature, a current and other information, whether the battery allows to be charged is determined; if the battery allows to be charged, the battery management system automatically adjusts a charging mode to the battery pack; through CAN communication, an output current of an equalization power supply module is automatically adjusted; equalization charging is performed on a single battery with a low voltage till that differential voltages of all the single batteries are less than a threshold. By using the system and the method of the invention, according to data information of the battery pack, a charging mode can be automatically selected, a charging current is automatically matched, a charging protection function is possessed, charging efficiency of the battery pack can be increased and a circulation service life of the battery pack is prolonged.
