接觸(chu)式充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的問(wen)題在(zai)于(yu)它的安全性和(he)通用性。為(wei)了(le)使它滿足嚴(yan)格(ge)(ge)的安全充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)標準，必須在(zai)電(dian)(dian)(dian)(dian)路上采用許(xu)多措施使充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)設備能夠在(zai)各種環境(jing)下(xia)(xia)安全充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，恒(heng)壓限流充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)和(he)分階段恒(heng)流充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)均屬于(yu)接觸(chu)式充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)技術。新型的電(dian)(dian)(dian)(dian)動汽(qi)車(che)感應充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)技術發展很快。感應充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)是(shi)(shi)(shi)利(li)用高頻交流磁場的變壓器(qi)原理(li)，將電(dian)(dian)(dian)(dian)能從離車(che)的原方感應到車(che)載的副方，汽(qi)車(che)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)樁價格(ge)(ge)，以達(da)到給蓄電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的目(mu)的。感應充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的優(you)點是(shi)(shi)(shi)安全，這是(shi)(shi)(shi)因為(wei)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)與車(che)輛之間并(bing)無直接的點接觸(chu)，即使車(che)輛在(zai)惡劣的氣候下(xia)(xia)，如雨雪天，進(jin)行充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)也(ye)無觸(chu)電(dian)(dian)(dian)(dian)的危險(xian)。

注意事項(xiang)。大家表(biao)示，由于(yu)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)過(guo)程中電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)內(nei)部(bu)會(hui)(hui)產生氣體和(he)熱量，但正常情況下能(neng)(neng)(neng)夠達到平衡。如果(guo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓過(guo)高，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)內(nei)部(bu)的(de)(de)化學反(fan)應加速，則平衡將被破(po)壞。一般(ban)來(lai)(lai)說(shuo)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器正常充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)可(ke)用2至3年左(zuo)右(you)，而(er)快速充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站比恒流恒壓的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流高了近10倍，嚴重超過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動車(che)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)設計的(de)(de)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)負荷，會(hui)(hui)傷害(hai)到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)內(nei)部(bu)構(gou)造。自19世(shi)紀輛電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動汽車(che)面(mian)世(shi)至今，均采用可(ke)充(chong)(chong)(chong)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)作為(wei)其動力源。對于(yu)一輛電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動汽車(che)來(lai)(lai)講，蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)設備(bei)是不可(ke)缺少的(de)(de)子系(xi)統之一。它的(de)(de)功(gong)能(neng)(neng)(neng)是將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)轉化為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動汽車(che)車(che)載(zai)(zai)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動汽車(che)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)裝置的(de)(de)分類有(you)不同的(de)(de)方法，總體上可(ke)分為(wei)車(che)載(zai)(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)裝置和(he)非車(che)載(zai)(zai)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)裝置。
