一种双锂电池组供电的混合动力汽车电池组设计

Design of dual lithium battery packs applied to hybrid power automobile

这里提出一种适用于混合动力汽车的双锂电池组供电方法。该混合动力汽车电池组由两个锂电池组组成,交替供电和充电。大量锂电池单体的串并联会因单体之间一致性差而降低电池组寿命和可靠性。这种设计不仅可以消除电池并联中因一致性差引起的不均衡电流,还能进一步提高电池组的可靠性。

The power supply method of the dual lithium battery packs applied to hybrid power automobile is presented. The dual lithium battery packs are composed of two battery packs. The method makes one battery pack supply power for the vehicle while another is charged. The lifetime and reliability of the battery pack are influenced by the poor consistency of the batteries while they are connected in series or parallel. The design can eliminate the unbalanced current problem created by the poor consistency of the paralleled batteries, and improve the reliability of the battery packs.
