摘要:

为避免个别单体的过充、过放导致电池组性能下降甚至失效,需对电池组中各单体之间实现均衡控制,从而提高电池组使用寿命。文中设计了一种基于STM32F103RB的电池组均衡控制器,提出了消除单体电池不一致性的均衡充电控制策略,为鉴别即将报废电池提供了理论依据。

Abstract:

To avoid battery performance degradation or even failure caused by individual monomer overcharge and over discharge,the balance control between monomer batteries is needed,so as to prolong battery service life.In this paper,the battery pack equalization controller is designed based on STM32F103RB,an equalizing charge control strategy is proposed for eliminating the inconsistency of single battery,and a theoretical basis for the identification of the upcoming end-of-life battery is provided.

Key words: lithium battery;performance degradation;STM32F103RB;equalization controller
