The invention discloses a power battery equalization system and method. The system comprises an equalization port formed in a vehicle and equalization equipment connected with the equalization port. The equalization port is provided with a plurality of connecting terminals, and each connecting terminal is connected to the positive electrode or the negative electrode of one battery string in the battery pack in a one-to-one correspondence manner; and the equalization equipment is connected with each connecting terminal so as to realize connection of each battery string and equalization of each battery string. The system has the advantages that a separated balancing mode is adopted, and the problem that the cost is high due to the fact that the balancing function is integrated in a vehicle is solved; the external equalization equipment can accurately and quickly realize equalization of any battery string in the battery pack; the balancing method is simple and reliable, convenient to use, low in equipment production cost and convenient to use at a maintenance point.

    本发明公开了一种动力电池均衡系统及方法,系统包括设置在车辆上的均衡口以及与均衡口连接的均衡设备;所述均衡口上设置多个连接端子,每个连接端子一一对应的连接至电池包中一个电池串的正极或负极;所述均衡设备通过与每一个连接端子连接从而实现连接每一个电池串并实现对每一个电池串的均衡。本发明的优点在于:采用分离式均衡方式,避免了将均衡功能集成在车辆中产生的成本高的问题;外置的均衡设备可以准确快速的实现电池包中任一电池串的均衡;均衡方法简单可靠,使用方便且设备生产成本低,方便维修点采用使用。
