众所周知，国家(jia)提倡绿色可持续发(fa)展。电(dian)(dian)动(dong)(dong)(dong)汽车(che)(che)行业新国标(biao)出(chu)台后，电(dian)(dian)动(dong)(dong)(dong)汽车(che)(che)的各项标(biao)准(zhun)都有严格的规定(ding)，尤其(qi)是电(dian)(dian)动(dong)(dong)(dong)车(che)(che)电(dian)(dian)池使用锂(li)电(dian)(dian)池，这意味(wei)着电(dian)(dian)动(dong)(dong)(dong)汽车(che)(che)的检测将(jiang)更(geng)加严格。另一(yi)方面(mian)，企业也需要具备(bei)3C认证和电(dian)(dian)动(dong)(dong)(dong)摩托(tuo)车(che)(che)资质。整体来(lai)说(shuo)，以(yi)锂(li)电(dian)(dian)池取代电(dian)(dian)动(dong)(dong)(dong)汽车(che)(che)的铅(qian)酸电(dian)(dian)池是比较受欢迎的。

电动(dong)汽车的铅酸蓄电池更(geng)换(huan)为锂电池如下：

1、了(le)解电(dian)(dian)(dian)(dian)(dian)动汽(qi)车用什(shen)么电(dian)(dian)(dian)(dian)(dian)池，电(dian)(dian)(dian)(dian)(dian)池的放(fang)电(dian)(dian)(dian)(dian)(dian)容量和速率 (大放(fang)电(dian)(dian)(dian)(dian)(dian)是多少); 建(jian)议(yi)更(geng)换的锂电(dian)(dian)(dian)(dian)(dian)池在(zai)放(fang)电(dian)(dian)(dian)(dian)(dian)方面与电(dian)(dian)(dian)(dian)(dian)动汽(qi)车原厂电(dian)(dian)(dian)(dian)(dian)池相(xiang)同；

2、了(le)解(jie)电动汽(qi)车(che)电机的大允许(xu)功(gong)率，建议锂(li)电池的大放电功(gong)率应低于(yu)电动汽(qi)车(che)电机的大允许(xu)功(gong)率，防止电机烧坏；

3、了(le)解电(dian)动汽车接线电(dian)线的(de)规格，检查电(dian)线允(yun)许(xu)的(de)大电(dian)流，防止过大的(de)电(dian)流烧毁(hui)电(dian)线；

4、了解电(dian)动汽车(che)其他电(dian)子元件的(de)允(yun)许电(dian)流极限，建议电(dian)流应小于允(yun)许电(dian)流极限值(zhi)；

5、锂(li)电池的外观尺寸(cun)。一(yi)般来说(shuo)，容量和放(fang)电相同的锂(li)电池比铅酸电池小得多。因此，在电动(dong)汽车中放(fang)置(zhi)电池的地方会(hui)有(you)缝隙，可以(yi)用绝缘材料填充(chong)，以(yi)防止(zhi)电池松动(dong)以(yi)及频繁或(huo)过度振动(dong)会(hui)发(fa)生(sheng)安全(quan)事(shi)故；

6、对(dui)于锂电池(chi)容量(liang)(liang)(liang)的(de)选(xuan)择(ze)，一般(ban)建议选(xuan)择(ze)与电动汽车原始电池(chi)相同的(de)容量(liang)(liang)(liang)。一般(ban)建议选(xuan)择(ze)容量(liang)(liang)(liang)的(de)两(liang)倍以下。如(ru)果(guo)容量(liang)(liang)(liang)太大，就会(hui)发(fa)生安(an)全事(shi)故；

7、锂(li)电(dian)(dian)(dian)池(chi)(chi)类型的选(xuan)(xuan)择(ze)。目(mu)前，电(dian)(dian)(dian)动汽(qi)车锂(li)电(dian)(dian)(dian)池(chi)(chi)有几种类型。18650锂(li)离子(zi)电(dian)(dian)(dian)池(chi)(chi)、磷(lin)酸铁锂(li)电(dian)(dian)(dian)池(chi)(chi)和聚合(he)物(wu)锂(li)电(dian)(dian)(dian)池(chi)(chi)。一般来说，如果从价格(ge)上来说，锂(li)电(dian)(dian)(dian)池(chi)(chi)单(dan)体(ti)是新的，锂(li)聚合(he)物(wu)电(dian)(dian)(dian)池(chi)(chi)的价格(ge)高，其(qi)次是磷(lin)酸铁锂(li)电(dian)(dian)(dian)池(chi)(chi)和18650低的锂(li)电(dian)(dian)(dian)池(chi)(chi)，因为在相同的容量规格(ge)下，锂(li)聚合(he)物(wu)电(dian)(dian)(dian)池(chi)(chi)的密度能量比更大，重量更轻。在安(an)全性能方面，磷(lin)酸铁锂(li)电(dian)(dian)(dian)池(chi)(chi)更好，其(qi)次是锂(li)电(dian)(dian)(dian)池(chi)(chi)18650。因此，这(zhei)取决于自己经济允(yun)许的选(xuan)(xuan)择(ze)。

8、在电(dian)(dian)池电(dian)(dian)压方面，需(xu)要(yao)注意的是，更(geng)换(huan)锂(li)电(dian)(dian)池时，原(yuan)厂铅(qian)酸电(dian)(dian)池需(xu)要(yao)与(yu)原(yuan)车(che)的电(dian)(dian)池电(dian)(dian)压保(bao)持(chi)一致，容量可(ke)以(yi)增(zeng)加，电(dian)(dian)池寿命更(geng)长。即使(shi)具有(you)相同的容量，锂(li)电(dian)(dian)池也将具有(you)更(geng)长的续(xu)航里(li)程和寿命。其次，需(xu)要(yao)注意的是，原(yuan)装充电(dian)(dian)器(qi)不能用锂(li)充电(dian)(dian)，需(xu)要(yao)单独购买或定制(zhi)专用充电(dian)(dian)器(qi)。

9、电(dian)(dian)动(dong)汽车的铅酸电(dian)(dian)池(chi)换成锂(li)(li)(li)电(dian)(dian)池(chi)，电(dian)(dian)池(chi)寿(shou)命会更长吗？正(zheng)常(chang)使用下，虽然锂(li)(li)(li)电(dian)(dian)池(chi)本身(shen)的大电(dian)(dian)流(liu)放电(dian)(dian)特(te)性是(shi)短板，在拥堵(du)路面频繁启动(dong)会影响电(dian)(dian)池(chi)寿(shou)命，但如果购买的锂(li)(li)(li)电(dian)(dian)池(chi)是(shi)正(zheng)规(gui)厂家生产的，并有bms管理系统，寿(shou)命比(bi)铅酸电(dian)(dian)池(chi)长得(de)多(duo)。

从(cong)国家绿色和可持续发展的角度来看，铅酸电池(chi)(chi)(chi)对环(huan)境污(wu)染的危害(hai)更(geng)大(da)，而锂电池(chi)(chi)(chi)更(geng)环(huan)保，因(yin)此(ci)锂电池(chi)(chi)(chi)更(geng)容易取(qu)代铅酸电池(chi)(chi)(chi)。
