摘要：
Active charge balancing is a commonly used method to increase the usable energy of a battery stack with serially connected battery cells with different cell capacities. In this article an active charge balancing method with a multiple winding transformer DC/DC converter is described. The advantage of active charge balancing is shown using a prototype with twelve serially connected Lithium ion battery cells. Moreover, the influence of the cell capacity variance and the influence of the balancing current on the discharging energy is investigated.
