電動車充電站充電通常要完成兩個*基本的任務，首先是盡可能快地使電池恢復額定容量，另一是使用小電流充電，電動車充電站補充電池因自放電而損失的能量，以維持電池的額定容量。
小區電動車充電站不易損傷電瓶
電動車充電站在充電過程中，鉛酸電池負極板上的硫酸鉛逐漸析出鉛，正極板上的硫酸鉛逐漸生成二氧化鉛。當正負極板上的硫酸鉛完全生成鉛和二氧化鉛后，電池開始發生過充電反應，產生氫氣和氧氣(這就是電池析氣)。這樣，在非密封電池中，電解液中的水將逐漸減少。在密封鉛酸蓄電池中，采用中等充電速率時，氫氣和氧氣能夠重新化合為水。過充電開始的時間(電池內部的安全電壓)與充電的速率有關。當充電速率大于C/5，電池容量恢復到額定容量的80%以前，即開始發生過充電反應。只有充電速率小于C/100，才能使電池在容量恢復到100%后，出現過充電反應。為了使電池容量恢復到100%，必須允許一定的過充電反應。
為方便物業對電動車充電管理，電動車主又得以方便及時的充電，投幣電動車充電站被研發，并且迅速發展并崛起。有了投幣充電站，再也不用私自牽拉電線，物業方的管理也方便輕松多了。在給電動車充電時只要插接上電動車自帶的充電器就可實現充電，而普通的220V電源給電動車充電，這樣正常的充電不容易損傷電瓶，也解決了車主的憂慮。
