電動汽車充電樁作為電動汽車的能量補給裝置，生產電表箱其充電性能關系到電池組的使用壽命、充電時間。電表箱哪家好這(zhe)也(ye)是(shi)消費者在購買電(dian)(dian)動汽(qi)車(che)之(zhi)前最為(wei)關心的一個方面之(zhi)一。實現(xian)對動力電(dian)(dian)池(chi)快速、高效、安全、合(he)理(li)的電(dian)(dian)量補(bu)給是(shi)電(dian)(dian)動汽(qi)車(che)充電(dian)(dian)器設計的基本(ben)原則，另外，還要考慮充電(dian)(dian)器對各種(zhong)動力電(dian)(dian)池(chi)的適(shi)用性。

由于(yu)(yu)電(dian)(dian)(dian)(dian)動(dong)汽車每天需要補(bu)充(chong)大量電(dian)(dian)(dian)(dian)能，經營(ying)(ying)充(chong)電(dian)(dian)(dian)(dian)站(zhan)就可(ke)(ke)(ke)以獲得(de)巨(ju)大的(de)(de)充(chong)電(dian)(dian)(dian)(dian)服務(wu)收益。相對(dui)(dui)于(yu)(yu)加油站(zhan)，電(dian)(dian)(dian)(dian)能比較安全(quan)和(he)方便(bian)，可(ke)(ke)(ke)在各地(di)大量安裝設(she)置充(chong)電(dian)(dian)(dian)(dian)站(zhan)。根(gen)據投資規模(mo)，小(xiao)到社區慢速充(chong)電(dian)(dian)(dian)(dian)樁(zhuang)，大到公路快速充(chong)電(dian)(dian)(dian)(dian)站(zhan)，單站(zhan)經營(ying)(ying)，組網(wang)經營(ying)(ying)均可(ke)(ke)(ke)。對(dui)(dui)于(yu)(yu)充(chong)電(dian)(dian)(dian)(dian)站(zhan)市(shi)場(chang)的(de)(de)開(kai)放，國(guo)家(jia)電(dian)(dian)(dian)(dian)網(wang)以后可(ke)(ke)(ke)能更(geng)多(duo)地(di)會偏(pian)向服務(wu)和(he)電(dian)(dian)(dian)(dian)力供應(ying)，讓充(chong)電(dian)(dian)(dian)(dian)站(zhan)建設(she)更(geng)充(chong)分地(di)與市(shi)場(chang)融合，大家(jia)都(dou)將(jiang)是同一個市(shi)場(chang)的(de)(de)競爭者。因此提(ti)前準備、提(ti)前規劃(hua)，對(dui)(dui)從事電(dian)(dian)(dian)(dian)池生產(chan)的(de)(de)企業來說(shuo)很重(zhong)要。充(chong)換電(dian)(dian)(dian)(dian)市(shi)場(chang)，政策有傾(qing)斜，市(shi)場(chang)有潛力，投資又少(shao)，將(jiang)面臨較大的(de)(de)商(shang)機。

控制柜(ju)是按電(dian)(dian)(dian)(dian)氣接線要求(qiu)將開關設(she)備、測量儀表、保護電(dian)(dian)(dian)(dian)器和輔助設(she)備組裝在封閉或(huo)(huo)半封閉金屬柜(ju)中(zhong)或(huo)(huo)屏幅上(shang)，其布置應滿足(zu)電(dian)(dian)(dian)(dian)力系(xi)統(tong)正(zheng)(zheng)常運行(xing)的(de)要求(qiu)，便于檢修，不危及(ji)(ji)人身及(ji)(ji)周圍(wei)設(she)備的(de)安全。正(zheng)(zheng)常運行(xing)時可(ke)借助手動或(huo)(huo)自動開關接通(tong)或(huo)(huo)分斷電(dian)(dian)(dian)(dian)路。故障或(huo)(huo)不正(zheng)(zheng)常運行(xing)時借助保護電(dian)(dian)(dian)(dian)器切(qie)斷電(dian)(dian)(dian)(dian)路或(huo)(huo)報警。借測量儀表可(ke)顯示(shi)運行(xing)中(zhong)的(de)各種參(can)數(shu)，還(huan)可(ke)對某些電(dian)(dian)(dian)(dian)氣參(can)數(shu)進行(xing)調(diao)整，對偏(pian)離正(zheng)(zheng)常工(gong)作狀態進行(xing)提示(shi)或(huo)(huo)發出信號。常用(yong)于各發、配、變電(dian)(dian)(dian)(dian)所中(zhong)。
