摘要
探讨了电源系统中浮充电压对阀控式铅酸蓄电池寿命的影响，要保证蓄电池的使用寿命，必须有合适的浮充电压。讨论了传统的均衡充电不适合阀控式铅酸蓄电池的原因，提出了蓄电池组主动均衡的方法。通过主动均衡，可以使电池电压达到足够的均衡精度，保证电池的安全稳定和延长电池的使用寿命。
This paper discusses VRLA battery life related to the floating voltage in standby power supply. To ensure the battery life, there must be appropriate floating voltage. We analyze the reason why the traditional equalizing charge method is not suitable for the VRLA battery. Based on the analysis, a way named by the battery active equalization is proposed. Through the active equalization, battery voltage can achieve a sufficient balance accuracy, which ensures the security and stability of the battery.
