Problems solved by technology
[0007] The main purpose of the present invention is to provide a method for serially charging at least one battery module with a charger, and monitor the power of the battery cells in each battery module through the battery monitoring unit, and then use the charging unit to charge the battery cells with too low power respectively. The equalizer and the battery module charging method using the equalizer solve the problem that the existing battery module needs to be equipped with an active or passive battery balancing circuit, thereby increasing the manufacturing cost, failing to effectively achieve balance efficiency and insufficient safety and reliability. Problems, which can effectively improve balance efficiency to prolong service life, reduce costs, and ensure safe use

The invention discloses an equalization charging device and a battery module charging method by using the same. The equalization charging device comprises multiple charging units and multiple battery monitoring units in electrical connection. According to the battery module charging method by using the same, a charger is firstly used for carrying out serial charging on at least one battery module, and the power of at least one battery core in the battery module reaches a preset standard value; the equalization charging device and the battery module are then connected, and the multiple battery monitoring units are used for monitoring the power of each battery core respectively; and according to different power of each battery core, the multiple battery monitoring units control the multiple charging units to charge each corresponding battery core respectively. Thus, each battery core can be fully charged in an equalization mode.
Description
technical field [0001] The invention relates to an equalizer and a battery module charging method using the equalizer, which can make the electric quantity of each battery core in the battery module be charged evenly, so as to improve the use efficiency and prolong the service life of the battery module. Background technique [0002] The battery management system (Battery Management System, BMS) is an essential core system for electric vehicles. It is mainly responsible for the safety monitoring and management of the battery module, so as to improve the efficiency and reliability of the battery module and prolong the service life of the battery module. The battery management system mainly includes a battery management unit (Battery Management Unit, BMU) and a battery module control unit (Battery Control Unit, BCU). The battery module management unit (BMU) can transmit relevant information through various communication protocols, and transmit the information to the battery mo...
