摘　　要：设计一种基于单片机控制的锂电池组管理系统,实现充放电控制和均衡控制,并具有防过充、过放、过流功能。提出一种新的充电方式,依据最低出气率为前提的电池可接受的最佳充电曲线;另外根据充电电池与均衡电阻热效应相等原理,提出了一种均衡算法。通过实验本系统能很好地实现锂电池组的充放电管理及均衡控制。A lithium-based MCU control group management system was designed with the functions of charge and discharge control,balance control,anti-overcharge protection,over-discharge protection,and over-current function protection.Based on the acceptable optimal charging curve with the lowest outlet as the premise,a new charging method was presented.A balancing algorithm was proposed according to the equal heating effect between the battery and the balance resistor.The experiment results show that the designed system can effectively control the charge and discharge of the lithium group and its balance.
