基于电流匹配的锂电池组端电压容差自愈方法
Current-matching-based self-healing method for terminal voltage tolerance in lithium battery packs
摘要
Abstract
A terminal voltage tolerance self-healing method based on current matching was proposed to address voltage inconsistency,incomplete charging,and accelerated capacity degradation in lithium battery packs after passive balancing.By real-time monitoring of balancing signals,the charg-ing loop duty cycle was dynamically adjusted to precisely match the average charging current with the balancing branch's dissipation current.Experimental results indicate that this method overcame the voltage divergence defect typical of traditional protection boards.It achieved cell voltage conver-gence at the end of charging(difference<30 mV)and ensured all cells reached a full charge state.This solution effectively enhances the available capacity and lifespan of the battery pack,achieves life consistency between the pack and individual cells,and is verified by an experimental prototype.关键词
