對許多的朋友來說無人機電池價格(ge)貴的(de)原因都(dou)不清楚(chu)，下面(mian)以格(ge)瑞普無人機電(dian)池(chi)為例，一般通用的(de)一塊5300毫(hao)安的(de)無人機電(dian)池(chi)售價在600塊左(zuo)右，而平時(shi)用的(de)充(chong)電(dian)寶(bao)20000毫(hao)安的(de)價格(ge)也就一到兩(liang)百元，為什么(me)(me)差別那(nei)么(me)(me)大呢?

因為無人機采用的聚合物鋰離子電池和充電寶所采用的鋰電池有所不同，之所以價格要(yao)貴很(hen)多，這(zhe)是因為相比于(yu)其他設備，無(wu)人(ren)機對電池(chi)(chi)的(de)性能要(yao)求(qiu)更高，因此無(wu)人(ren)機電池(chi)(chi)價格要(yao)高很(hen)多。

下面從(cong)幾方面來說明原因(yin)：

首先是電(dian)(dian)(dian)(dian)池(chi)性能(neng)(neng)(neng)不同(tong)，無(wu)人(ren)機需(xu)要(yao)(yao)克服自身的(de)(de)重(zhong)力(li)做功(gong)，因(yin)此，對(dui)于電(dian)(dian)(dian)(dian)池(chi)的(de)(de)重(zhong)量要(yao)(yao)求較(jiao)高(gao)(gao)，而(er)增大電(dian)(dian)(dian)(dian)池(chi)容量又(you)會導(dao)致(zhi)重(zhong)量增加，因(yin)此，只(zhi)有(you)同(tong)樣容量下重(zhong)量較(jiao)輕(qing)的(de)(de)聚(ju)合物鋰離子(zi)電(dian)(dian)(dian)(dian)池(chi)能(neng)(neng)(neng)夠(gou)滿(man)(man)足(zu)需(xu)要(yao)(yao)，另一方面(mian)，無(wu)人(ren)機對(dui)于電(dian)(dian)(dian)(dian)池(chi)的(de)(de)功(gong)率的(de)(de)要(yao)(yao)求特別高(gao)(gao)，當從(cong)懸停狀態(tai)迅速提高(gao)(gao)油門到(dao)(dao)最高(gao)(gao)速度，電(dian)(dian)(dian)(dian)池(chi)功(gong)率會迅速提高(gao)(gao)，短(duan)時(shi)間內幾(ji)倍的(de)(de)功(gong)率提高(gao)(gao)，這樣的(de)(de)功(gong)率變化只(zhi)有(you)聚(ju)合物鋰離子(zi)電(dian)(dian)(dian)(dian)池(chi)能(neng)(neng)(neng)夠(gou)滿(man)(man)足(zu)，實際(ji)上充電(dian)(dian)(dian)(dian)寶電(dian)(dian)(dian)(dian)池(chi)通過(guo)串并聯也能(neng)(neng)(neng)達到(dao)(dao)這樣的(de)(de)要(yao)(yao)求，特斯拉汽車的(de)(de)電(dian)(dian)(dian)(dian)池(chi)便是7000多塊(kuai)18650電(dian)(dian)(dian)(dian)池(chi)串并聯在(zai)一起，從(cong)而(er)能(neng)(neng)(neng)夠(gou)承受瞬間的(de)(de)大功(gong)率需(xu)求，這在(zai)無(wu)人(ren)機上明(ming)顯不適合。因(yin)此，從(cong)性能(neng)(neng)(neng)上來說(shuo)，只(zhi)有(you)聚(ju)合物鋰離子(zi)電(dian)(dian)(dian)(dian)池(chi)能(neng)(neng)(neng)夠(gou)滿(man)(man)足(zu)這樣的(de)(de)使用(yong)需(xu)求。

當(dang)然即使(shi)是(shi)聚合物(wu)鋰離(li)(li)子(zi)電(dian)池(chi)在(zai)無人機上(shang)消(xiao)耗也非(fei)常(chang)快，格瑞普一(yi)(yi)塊5300mah的電(dian)池(chi)，使(shi)用在(zai)客機模型無人機上(shang)，可(ke)以飛高(gao)達40分鐘(zhong)以上(shang)，而一(yi)(yi)款20000mah的充電(dian)寶容納(na)的能量一(yi)(yi)般(ban)5800mah的電(dian)池(chi)理想狀態(tai)下(xia)(xia)只(zhi)能支撐20分鐘(zhong)的飛行時間，如(ru)果是(shi)用在(zai)比賽或是(shi)需要瞬時高(gao)功率(lv)運作(zuo)的情況下(xia)(xia)，基本不能用，可(ke)以想象對電(dian)池(chi)的壓力有多大，聚合物(wu)鋰離(li)(li)子(zi)電(dian)池(chi)長期在(zai)這(zhe)種工作(zuo)環境下(xia)(xia)，電(dian)池(chi)損耗非(fei)常(chang)快，并且(qie)短時間內快速放電(dian)也會導致(zhi)電(dian)池(chi)溫(wen)度快速升高(gao)，這(zhe)些都(dou)使(shi)得無人機電(dian)池(chi)需要更(geng)進(jin)一(yi)(yi)步的安全保(bao)護。

格瑞普(pu)無人(ren)機電(dian)(dian)(dian)池(chi)(chi)稱為(wei)智(zhi)能(neng)(neng)飛(fei)行電(dian)(dian)(dian)池(chi)(chi)，這(zhe)是因為(wei)除了(le)(le)聚合物鋰(li)離子電(dian)(dian)(dian)池(chi)(chi)之(zhi)外，該(gai)電(dian)(dian)(dian)池(chi)(chi)上(shang)還具備更多的(de)部件。首先，為(wei)了(le)(le)保(bao)護電(dian)(dian)(dian)池(chi)(chi)的(de)長(chang)時(shi)間(jian)工作安全(quan)，電(dian)(dian)(dian)源管理系統能(neng)(neng)夠對電(dian)(dian)(dian)池(chi)(chi)進(jin)行充放電(dian)(dian)(dian)保(bao)護，能(neng)(neng)夠始(shi)終(zhong)讓電(dian)(dian)(dian)池(chi)(chi)工作在安全(quan)的(de)范圍內，其次(ci)，如果電(dian)(dian)(dian)池(chi)(chi)長(chang)期滿電(dian)(dian)(dian)擱(ge)置會(hui)對電(dian)(dian)(dian)池(chi)(chi)壽命產生影響，大疆智(zhi)能(neng)(neng)電(dian)(dian)(dian)池(chi)(chi)內置有電(dian)(dian)(dian)池(chi)(chi)存儲自放電(dian)(dian)(dian)保(bao)護，長(chang)時(shi)間(jian)擱(ge)置情(qing)況下能(neng)(neng)夠自動放電(dian)(dian)(dian)，延長(chang)電(dian)(dian)(dian)池(chi)(chi)的(de)使用(yong)時(shi)間(jian)。

因(yin)(yin)此，不(bu)論是從(cong)性能(neng)還是安全角度考慮，無人機電池(chi)的使(shi)用要(yao)(yao)求都要(yao)(yao)比(bi)普通的充電寶(bao)所用的電池(chi)要(yao)(yao)高得(de)多，這也使(shi)得(de)其價(jia)格(ge)的原因(yin)(yin)。
