摘要
报导了直流操作电源 (直流屏 )中铅酸蓄电池的过充电保护与温度补偿特性的模拟试验研究结果 .试验发现 :处于浮充方式工作下的铅酸蓄电池 ,过充电是造成其提前失效的主要因素 .为了延长电力系统中铅酸蓄电池的使用寿命 ,必须对蓄电池进行充电保护及对过充阈值电压进行温度补偿 ,过充阈值电压温度补偿系数对单体电池而言在 - 3.5～ - 4 .5mV/℃范围内较为合理 .就过充电阈值电压进行温度补偿的方式而言 。
Reported are some investigation results of overcharging protection and temperature compensation characteristics of lead acid battery used in electrical power systems. The results show that overcharging is responsible for early failure of battery used in electrical systems. To prolong life of battery, protection and temperature compensation of end of charge voltage are necessary for systems. It is reasonable to set coefficient of temperature compensation ranging for -3.5 to -4.5 mV/℃ per cell, and it is concluded that, linear temperature compensation for threshold voltage of overcharging is better than step temperature compensation.
