加酸化成与电池低温容量关系

The relationship of formation and the capacity at low temperature

加入的电解液温度越高,铅酸蓄电池温升越大,持续时间越长。加入温度较低的电解液,加入电解液后采取冷却措施,降低冷却水温度,都有利于提高电池的低温容量。化成过程中,循环水温度超过45℃,低温容量大幅降低。连铸连轧电池(极板未淋酸)加入电解液后温升幅度比常规电池更高,持续时间更长,低温容量更低。采用较低电解液温度、冷却水温度、化成温度可以有效提高连铸连轧电池的低温容量。

The higher temperature of electrolyte filled into lead-acid battery,the higher temperature the battery will reach and longer time the high temperature will sustain.Adding low temperature electrolyte is in favor of improving the capacity at low temperature.During the formation,if the cycled water is above 45℃,the capacity will have a sharply decrease.For the continuous casting and rolling and punching(CCRP)grid battery,the battery temperature will reach a higher level than the casting grid battery and high temperature will sustain longer time.But the capacity at low temperature is lower than the casting grid battery.Lowering the temperatures of electrolyte,cooling water and formation is an effective method to improve low capacity of the CCRP grid battery.
