提高铅酸蓄电池寿命方法的研究

首次提出在铅酸蓄电池内部加装可控点燃装置的方法,来提高铅酸蓄电池的循环寿命。原理是采用三段大电流脉冲过充电提高铅酸蓄电池组充电电压,加大充电电流,可控点燃装置点燃充电过程中产生的氢气和氧气,提高氢、氧的复合率。通过对同类型铅酸蓄电池内部的压力测量,不同工作模式时容量衰减比对,对铅酸蓄电池的循环寿命进行了研究。研究表明:铅酸蓄电池内部的气体压力减小,循环寿命比同类铅酸蓄电池提高1.5～2倍,深循环寿命可达600次。

Research of improving lead-acid storage battery life-span

The way of adding a controlled firing device inside the lead-acid storage battery was brought forward firstly to enhance the cycle life-span of lead-acid storage battery in this paper.The charging volt of the lead-acid storage battery group and the charging current could be improved by the way of three sections heavy current pulse over-charging.The controlled firing device fired the hydrogen and oxygen produced in the charging process to improve the hydrogen and oxygen recombination rate.By measuring the internal pressure of different types of lead acid batteries,and comparing the capacity attenuation in different working modes,the life of lead acid batteries were researched.The results show that the internal pressure of the battery is reduced,the life is extended by 1.5 ~ 2 times comparing with the similar types of batteries,and the deep cycle life can reach 600 times.
