电动汽车电池均衡技术综述

Review of EV Battery Balancing Technologies

动力电池有限的使用寿命和续航能力已成为限制电动汽车普及的瓶颈因素,实现对动力电池快速、高效、均衡充电成为电动汽车中急需解决的一项关键技术。介绍动力电池不一致性及其危害,并分类剖析了几种典型的均衡电路的工作原理,最后对均衡控制系统实现产业化需要考虑的因素进行分析。

Limited life cycle and endurance of motive battery is becoming the obstacle in electronic vehicle populari- zing, and fast and efficient battery balancing charge might be the technology most needed to developed in time. In this paper, what inconsistency of battery endangers is firstly described. And then the principles of the most influent balancing methods are described. In the final part of this paper, the factors which need to be taken into account in the actual EV battery balancing system are outlined.
