由于電動汽車每天需要補充大量電能，汽車充電樁經營充電站就可以獲得巨大的充電服務收益。相對于加油站，電能比較安全和方便，可在各地大量安裝設置充電站。根據投資規模，小到社區慢速充電樁，大到公路快速充電站，單站經營，組網經營均可。對于充電站市場的開放，訂做汽車充電樁國家(jia)電網以后可能(neng)更(geng)多(duo)地(di)(di)會偏向服務和電力供應，讓充(chong)(chong)(chong)電站建設(she)更(geng)充(chong)(chong)(chong)分地(di)(di)與(yu)市(shi)(shi)場(chang)(chang)融合(he)，大家(jia)都將是同一個市(shi)(shi)場(chang)(chang)的競爭(zheng)者(zhe)。因此提前準(zhun)備(bei)、提前規劃，對從事電池(chi)生產的企業來(lai)說很重要(yao)。充(chong)(chong)(chong)換(huan)電市(shi)(shi)場(chang)(chang)，政(zheng)策有傾斜(xie)，市(shi)(shi)場(chang)(chang)有潛力，投(tou)資(zi)又(you)少，將面(mian)臨較大的商機。
