摘要
阀控密封铅蓄电池的某些特性参数跟电池荷电态的关系有可能用于预测电池的荷电态;采用两个参数联合起来判别电池荷电态比单个参数更有效。开路电压/电池内阻法、电化学极化内阻/双层电容法、开路电压/短时间放电电压法,已为人们所采用,单独测取开路电压或内阻都无法预测密封铅蓄电池的荷电态。
The relations between some special parameters of VRLA battery and stateofcharge (SOC) might be used to evaluate SOC. It was more effective to combine two parameters,not only one for evaluation of the stateofcharge for VRLA battery.Open circuit voltage(OCV)/internal resistance method, electrochemical polarization internal resistance/doublelayer capacitance method and OCV/ voltage after discharging for a short time method had been used. It was impossible to evaluate SOC of VRLA battery by means of the OCV or internal resistance measurement alone.
