摘　　要：针对锂电池组充放电过程中的单体均衡问题，基于实时单体参量高精度检测与快速反馈调节原理，设计并实现了一种便携式锂电池组单体电压在线主动均衡系统。该系统在蓄电池组使用过程中的实时采集电压、电流、温度等电池参量，通过蓄电池组总电压给单体充电的方式，实现了蓄电池组各个单体过充、欠充、过放、过温条件下单体间的均衡进而保证安全供能的目标。A portable lithium battery cell vohage line active balancing system was designed and implemented,aiming for the monomer equilibrium problems of lithium batteries during charge and discharge period, based on real-time high-precision detection and rapid parametric feedback regulation principles. The system was used in the process of the battery pack by detecting real-time acquisition voltage,current,temperature and other parameters of the battery. The system achieved every single battery＇s overcharge, charge less, over discharge, over -temperature condition between monomers initiative balance by charging monomer from the total voltage to ensure safe power target.
