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
