電池早已落戶全國千家萬戶，成為日常使用的必需品。但是對于玩具無人機電池的了解(jie)很片面(mian)。使(shi)用過程中總會遇見(jian)或多或少的懵逼情(qing)況。沒關系，我們這次歸納了比較常見(jian)的電池檢查注(zhu)意事項，一(yi)起(qi)來(lai)學(xue)習一(yi)下(xia)吧！

玩具無人機電池充電自查不可少

理(li)(li)論(lun)上，電(dian)池能夠重復充電(dian)和放電(dian)至少250次。而且，如果理(li)(li)論(lun)容量(liang)降(jiang)低到小于可用額(e)定容量(liang)的(de)40％，則認為(wei)電(dian)池壽(shou)命耗盡。這是因為(wei)開(kai)始很(hen)困難。然而，在真實的(de)情況下，如果只有30％的(de)容量(liang)不足難以(yi)啟動。

例如(ru)，假設暗電(dian)(dian)流（空載狀態下的(de)放(fang)電(dian)(dian)電(dian)(dian)流）約(yue)為(wei)100mA（該電(dian)(dian)流僅為(wei)繼電(dian)(dian)器線圈(quan)驅動(dong)(dong)電(dian)(dian)流），60Ah電(dian)(dian)池為(wei)60Ah。計(ji)算0.3 = 18Ah，并(bing)且可以通過將該30％容(rong)量除以放(fang)電(dian)(dian)電(dian)(dian)流來計(ji)算電(dian)(dian)池的(de)壽命(ming)。換(huan)句話說，18Ah÷0.1A = 180h意味著發動(dong)(dong)機不(bu)會在180小時(shi)內(nei)啟(qi)動(dong)(dong)，并(bing)且在大約(yue)7.5天內(nei)不(bu)會啟(qi)動(dong)(dong)。

結(jie)論是，如果用60Ah的(de)電(dian)(dian)(dian)池(chi)(chi)放(fang)電(dian)(dian)(dian)7天并放(fang)電(dian)(dian)(dian)100mA，它將無法啟動。放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)在無負(fu)載條(tiao)件下，但在理論上20?30毫安，基于(yu)（有根據(ju)型(xing)號的(de)微小差(cha)異）和(he)所測量的(de)電(dian)(dian)(dian)壓和(he)所述充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)波形CCA維護，如果三個標準(zhun)的(de)標準(zhun)是至(zhi)50mA。此外，當電(dian)(dian)(dian)池(chi)(chi)存放(fang)或長時間停放(fang)時，電(dian)(dian)(dian)池(chi)(chi)本身經常自(zi)行放(fang)電(dian)(dian)(dian)。隨著時間的(de)推(tui)移，電(dian)(dian)(dian)池(chi)(chi)內部(bu)發(fa)生化學(xue)反應(ying)和(he)放(fang)電(dian)(dian)(dian)。這種現象被歸因于(yu)等的(de)影響稱為自(zi)放(fang)電(dian)(dian)(dian)如果通過分離和(he)雜質積累(lei)，銻含量，板柵包括(kuo)電(dian)(dian)(dian)池(chi)(chi)流(liu)體(ti)的(de)短路是自(zi)放(fang)電(dian)(dian)(dian)。自(zi)放(fang)電(dian)(dian)(dian)取(qu)決于(yu)電(dian)(dian)(dian)池(chi)(chi)的(de)老化，并且發(fa)展到每天容量的(de)約0.2-1.0％。

據說完全充電(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)池在約15℃下完全放(fang)電(dian)(dian)(dian)(dian)約4個月并在約40℃下完全放(fang)電(dian)(dian)(dian)(dian)約2周。自放(fang)電(dian)(dian)(dian)(dian)的程度難以判(pan)斷，但是通過觀察啟動時的內部電(dian)(dian)(dian)(dian)阻(zu)，即電(dian)(dian)(dian)(dian)壓下降量或(huo)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流來判(pan)斷。
