锂电池电动(dong)车

锂(li)电(dian)(dian)池(chi)(chi)(chi)(chi)电(dian)(dian)动车华丽简练的(de)外形，被越来(lai)越多的(de)被消费者接受，现在市面(mian)(mian)上，卖的(de)最多的(de)还是铅(qian)酸电(dian)(dian)池(chi)(chi)(chi)(chi)电(dian)(dian)动车，但有不(bu)少地区开始引(yin)进锂(li)电(dian)(dian)池(chi)(chi)(chi)(chi)电(dian)(dian)动车了(le)。锂(li)电(dian)(dian)池(chi)(chi)(chi)(chi)电(dian)(dian)动车顾名思(si)义，简单来(lai)说就是把铅(qian)酸换成了(le)锂(li)电(dian)(dian)池(chi)(chi)(chi)(chi)而已(yi)。如今国家大力提倡节(jie)能(neng)、绿色、环保(bao)，真的(de)能(neng)普及(ji)开来(lai)，等等问(wen)题.（下面(mian)(mian)我们浅谈(tan)浅谈(tan)电(dian)(dian)动锂(li)电(dian)(dian)池(chi)(chi)(chi)(chi)如何保(bao)养(yang)）

第一(yi)对于(yu)电(dian)(dian)(dian)动车锂电(dian)(dian)(dian)池(chi)进行(xing)部分(fen)放(fang)(fang)电(dian)(dian)(dian)，而不(bu)是完(wan)全放(fang)(fang)电(dian)(dian)(dian)，并(bing)且要(yao)尽量避免经常的完(wan)全放(fang)(fang)电(dian)(dian)(dian)。一(yi)旦电(dian)(dian)(dian)池(chi)下了生产线，时钟就(jiu)开始(shi)走动。不(bu)管你是否使(shi)用(yong)(yong)，锂电(dian)(dian)(dian)池(chi)的使(shi)用(yong)(yong)寿命都只(zhi)在两到三年。

电(dian)池(chi)容(rong)量(liang)(liang)的(de)下降是由于氧化引起的(de)内(nei)部电(dian)阻(zu)增加(这是导致电(dian)池(chi)容(rong)量(liang)(liang)下降的(de)主(zhu)要原因)。最后，电(dian)解槽(cao)电(dian)阻(zu)会达到某个点，尽管这时(shi)电(dian)池(chi)充满电(dian)，但电(dian)池(chi)不能释放已储存的(de)电(dian)量(liang)(liang)。

锂电(dian)池(chi)的老化速度是由温度和(he)充电(dian)状态(tai)而(er)决定的。下表(biao)说(shuo)明了两种(zhong)参数下电(dian)池(chi)容量(liang)的降低(di)。

温度(du) 充电40% (推(tui)荐(jian)) 充电100%

0°c 98% 一(yi)年后(hou) 94% 一(yi)年后(hou)

25°c 96% 一年后 80% 一年后

40°c 85% 一(yi)(yi)年后(hou) 65% 一(yi)(yi)年后(hou)

60°c 75% 一年后 60% 三个月(yue)后

由此可见，高充电(dian)(dian)状(zhuang)态和增加的温度加快了电(dian)(dian)池(chi)容(rong)量(liang)的下(xia)降。如果可能的话，尽量(liang)将电(dian)(dian)池(chi)充到(dao)40%放(fang)置(zhi)(zhi)于阴凉地方。这样可以(yi)在(zai)长时间的保存期内使电(dian)(dian)池(chi)自身(shen)的保护电(dian)(dian)路运作(zuo)。如果充满电(dian)(dian)后将电(dian)(dian)池(chi)置(zhi)(zhi)于高温下(xia)，这样会对电(dian)(dian)池(chi)造成(cheng)极大(da)的损(sun)害。(因(yin)此当我们使用(yong)固定电(dian)(dian)源的时候(hou)，此时电(dian)(dian)池(chi)处于满充状(zhuang)态，温度一般(ban)是(shi)在(zai)25-30°c之间，这样就会损(sun)害电(dian)(dian)池(chi)，引起其(qi)容(rong)量(liang)下(xia)降)。

一(yi)些(xie)电(dian)(dian)(dian)池由于(yu)过(guo)分的(de)低放(fang)电(dian)(dian)(dian)也(ye)会报废。如果放(fang)到每单元2.5伏(fu)特以下(xia)，电(dian)(dian)(dian)池内部(bu)的(de)安(an)全(quan)电(dian)(dian)(dian)路就(jiu)会开(kai)动，电(dian)(dian)(dian)池就(jiu)有些(xie)不好用啦。但是，如果电(dian)(dian)(dian)池下(xia)降到每单元1.5伏(fu)特以下(xia)，并(bing)保持该状态(tai)一(yi)些(xie)时日了，为安(an)全(quan)起见(jian)，就(jiu)不要对电(dian)(dian)(dian)池充(chong)电(dian)(dian)(dian)了。为避免这类情况的(de)发生，不要储存完(wan)全(quan)放(fang)电(dian)(dian)(dian)的(de)电(dian)(dian)(dian)池。应该在储存之前充(chong)一(yi)些(xie)电(dian)(dian)(dian)，并(bing)且(qie)在使用前充(chong)满(man)电(dian)(dian)(dian)。

总而言之(zhi)，在锂电(dian)(dian)池(chi)(chi)使用(yong)过程中避(bi)免完全(quan)放(fang)电(dian)(dian)，经(jing)常对(dui)锂电(dian)(dian)池(chi)(chi)充电(dian)(dian)。反复(fu)随意的(de)充电(dian)(dian)不(bu)会损害电(dian)(dian)池(chi)(chi)。将(jiang)锂电(dian)(dian)池(chi)(chi)置(zhi)于(yu)阴凉处(chu)，而不(bu)要进(jin)行冷冻(dong)。避(bi)免放(fang)在高温的(de)汽车(che)内。如长(zhang)时间保存，将(jiang)电(dian)(dian)池(chi)(chi)充到40%后放(fang)置(zhi)。如果你多数时间是(shi)使用(yong)固定(ding)电(dian)(dian)源，取下电(dian)(dian)池(chi)(chi)置(zhi)于(yu)阴凉处(chu)。
