转移式电池均衡技术对电池电压与荷电量影响的研究

摘要

The voltage and charged capacity of each single battery in the battery pack change constantly and are unbalanced in the process of charging and discharging, and the situation gets more and more worse with the increase in charging and discharging cycle, and the“weak”batteries in the battery pack become weak even harder as the running process continues and bring the battery pack in an overcharged or overdischarged state seriously affecting the normal energy storage and discharge of the whole battery pack. Transfer type battery equalization technology can keep the voltage and charged capacity of each battery being in the best state of equilibrium by using the pulse technique and the equilibrium mechanism to actively equalize each single battery voltage and charged capacity, thus prolonging the service life of the battery group.%电池组中各单只电池的电压和荷电量在反复充放电过程中时刻发生变化，逐渐呈不均衡状态，并且随充放电次数的增加而加重，“落后”电池愈加落后，直至过充电或过放电损坏，严重影响整个电池组的正常蓄电和放电。转移式电池均衡技术通过脉冲技术和均衡机理主动均衡各单只电池的电压和荷电量，使每只电池的电压和荷电量始终处于最佳均衡状态，有效延长电池组的使用寿命。
