摘要:所谓电池充电接受能力,是指蓄电池在一定放电深度、恒定电压、特定环境温度下的充电过程中,放电产物接受充入电荷所发生电化学反应的能力。电池充电电流要接近电池可接受的电流。所以在进行电池充电接受能力试验时,恒压充电限流值大小的选择可以说非常的重

Abstract: The so-called charge acceptance refers to the electrochemical reaction ability of a secondary battery to increase its state of charge under the specified conditions of depth of discharge, voltage and ambient temperature.The charging current should be as close as possible acceptable current.When the charge acceptance test was conducted, selecting constant voltage limiting current charging value was very important. This paper discussed the influence of different limiting current conditions on charge acceptance ability of the battery.
Key words: electric bicycle; charge acceptance; different limiting current value; electrochemical reaction ability

充电电流值,用电流大小来表示蓄电池的充电接受能力。充电接受能力反应出放电产物重新恢复为活性物质的难易程度,也反应出电池的可逆状况,是衡量二次电池性能的重要指标。充电接受能力好可保证电池正常使用及具有较长的循环使用寿命。 VRLA电池一般采用恒压限流的方式充电,充电电压高,充入的电量大,但在较高的电压下充电,会导致水的损耗使电池干失效,因此VRLA电池的充电恒压值不宜太高,在这种条件下,要保证电池在
