固定型VRLA电池再充电特性的研究

Research on recharging performance of stationary VRLA batteries

研究了固定型VRLA电池在不同充电条件下的再充电特性。结果表明:在均衡充电条件下,电池的放电容量可以100%恢复,电池的再充电特性极好;在浮充充电条件下,单体电池的再充电特性符合标准要求。因为均衡充电有利于提高电池的均匀一致性,所以在实际应用中,应定期对电池组进行均衡充电,避免电池自放电造成硫酸铅逐步积累,产生劣化单体电池。

The recharging performance of stationary VRLA batteries under the different charging conditions were studied in this paper.Test results showed that battery discharge capacity could be recovered up to100%and the recharging feature was excellent under the equalizing charge condition.Under the condition of float charging the recharging performance of each cell conformed to the requirements of national standard.Because equalizing charge could help improving the uniform consistency of battery pack,the battery should be regularly charged in the process of practical application to avoid the gradual accumulation of lead sulfate from self-discharge and resulting in degradation of cells.
