電(dian)(dian)(dian)池(chi)(chi)是無人(ren)(ren)(ren)機(ji)的(de)(de)能源來源之一(yi)。沒有電(dian)(dian)(dian)池(chi)(chi)，無人(ren)(ren)(ren)機(ji)就(jiu)無法移動(dong)。毫不夸張地說，由(you)于電(dian)(dian)(dian)池(chi)(chi)技(ji)術的(de)(de)進步，今天的(de)(de)無人(ren)(ren)(ren)機(ji)可以在這(zhe)個程(cheng)度上使(shi)用(yong)(yong)，電(dian)(dian)(dian)池(chi)(chi)是一(yi)個重要的(de)(de)部(bu)分。有人(ren)(ren)(ren)問。“我應該購買(mai)多少額外(wai)的(de)(de)電(dian)(dian)(dian)池(chi)(chi)？” 有時(shi)當被要求回答像知識(shi)分子這(zhe)樣的(de)(de)問題(ti)時(shi)，然后我會告(gao)訴你(ni)飛行時(shi)間(jian)和充(chong)電(dian)(dian)(dian)時(shi)間(jian)。當我推薦無人(ren)(ren)(ren)機(ji)時(shi)，由(you)于無人(ren)(ren)(ren)機(ji)的(de)(de)電(dian)(dian)(dian)池(chi)(chi)飛行時(shi)間(jian)非常(chang)短(duan)，因此如(ru)果(guo)您(nin)不購買(mai)額外(wai)的(de)(de)電(dian)(dian)(dian)池(chi)(chi)，否則您(nin)將無法正常(chang)使(shi)用(yong)(yong)無人(ren)(ren)(ren)機(ji)。例如(ru)，在用(yong)(yong)于玩具的(de)(de)迷你(ni)無人(ren)(ren)(ren)機(ji)的(de)(de)情況下，充(chong)電(dian)(dian)(dian)時(shi)間(jian)約60分鐘，但飛行時(shi)間(jian)約5分鐘。因此，我會給你(ni)告(gao)訴東(dong)西。然而今天我將為你(ni)們(men)介紹(shao)無人(ren)(ren)(ren)機(ji)的(de)(de)能量來源-電(dian)(dian)(dian)池(chi)(chi)的(de)(de)一(yi)些(xie)知識(shi)！

1.無人(ren)機電池(chi)使(shi)用的是什么類型(xing)的電池(chi)？

無人機使用的鋰聚合物電池。它簡稱為鋰電池。過去，已經使用過其他類型的電池，現在使用的大多數是鋰聚合物電池。像鎳鎘電池，鎳氫電池，鉛(qian)酸電(dian)池(chi)(chi)以及(ji)錳電(dian)池(chi)(chi)或堿性電(dian)池(chi)(chi)，都不(bu)能用(yong)在(zai)無(wu)人(ren)(ren)機(ji)上(shang)。其中(zhong)，無(wu)人(ren)(ren)機(ji)中(zhong)使(shi)用(yong)的(de)(de)鋰(li)(li)聚合(he)物電(dian)池(chi)(chi)近(jin)用(yong)于便(bian)攜式設備的(de)(de)類型，并(bing)且(qie)(qie)(qie)是(shi)(shi)鋰(li)(li)離子電(dian)池(chi)(chi)的(de)(de)下一代電(dian)池(chi)(chi)。鋰(li)(li)聚合(he)物電(dian)池(chi)(chi)由凝膠型電(dian)解質制(zhi)成(cheng)，其降低了(le)爆炸的(de)(de)風險(xian)并(bing)且(qie)(qie)(qie)可(ke)以制(zhi)成(cheng)各種薄(bo)的(de)(de)形狀，使(shi)其成(cheng)為(wei)通常用(yong)作移動電(dian)話的(de)(de)電(dian)池(chi)(chi)。然而，它的(de)(de)缺(que)點在(zai)于它具有比鋰(li)(li)離子電(dian)池(chi)(chi)更(geng)小的(de)(de)容(rong)量和更(geng)短(duan)的(de)(de)壽命。它也(ye)比鋰(li)(li)離子電(dian)池(chi)(chi)危險(xian)性小，而且(qie)(qie)(qie)鋰(li)(li)聚合(he)物電(dian)池(chi)(chi)也(ye)具有爆炸性，應該要很好的(de)(de)使(shi)用(yong)及(ji)保存。由于過(guo)度充(chong)電(dian)會有火(huo)災的(de)(de)危險(xian)，特別是(shi)(shi)那些偶爾(er)購買無(wu)人(ren)(ren)機(ji)的(de)(de)人(ren)(ren)。

2.閱讀電池規格

與構成(cheng)無人機的(de)所有(you)部件一樣，您需(xu)要(yao)了解(jie)(jie)規(gui)格以了解(jie)(jie)有(you)關(guan)電池的(de)更多信息。在查看電池規(gui)格時，您只需(xu)要(yao)知道三(san)件事。

電(dian)壓：這是以(yi)(yi)V（伏特）為單(dan)位(wei)表示(shi)的(de)值。 容量：以(yi)(yi)mAh（毫安(an)時）表示(shi)的(de)值。 放電(dian)率：以(yi)(yi)C單(dan)位(wei)表示(shi)的(de)數值。

首先，如果你看(kan)一下電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，每個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)數是(shi)(shi)3.7V。（因(yin)(yin)為我們經(jing)常(chang)使用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)參(can)考電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)為1.5V）。當它被緩沖時(shi)，它上升到(dao)4.2V并(bing)且在(zai)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)下降到(dao)3.3V。但(dan)(dan)是(shi)(shi)，參(can)考電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)是(shi)(shi)3.7V。因(yin)(yin)此，了解電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)值可(ke)(ke)以告訴您(nin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)串(chuan)聯(lian)(lian)連(lian)(lian)接(jie)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)數量。在(zai)某些情況下，它通過電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)單(dan)(dan)元(yuan)的(de)連(lian)(lian)接(jie)方法表(biao)(biao)示(shi)而(er)根(gen)本不(bu)顯示(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)。單(dan)(dan)元(yuan)連(lian)(lian)接(jie)方式表(biao)(biao)示(shi)為S（串(chuan)聯(lian)(lian)），P（并(bing)聯(lian)(lian)），但(dan)(dan)串(chuan)聯(lian)(lian)時(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)較高(gao)。因(yin)(yin)此，存在(zai)使用1s，2s，3s，4s等代替電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)表(biao)(biao)示(shi)法的(de)情況。1s是(shi)(shi)3.7V，2s是(shi)(shi)7.4V以此類(lei)推(tui)。并(bing)聯(lian)(lian)連(lian)(lian)接(jie)時(shi)使用P單(dan)(dan)元(yuan)。幾乎不(bu)需要將傳(chuan)感器無人機或賽車無人機連(lian)(lian)接(jie)起來。簡單(dan)(dan)地說，并(bing)聯(lian)(lian)連(lian)(lian)接(jie)將總(zong)結(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)容量。如果連(lian)(lian)接(jie)2個(ge)容量為1,500mAh的(de)2個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，則總(zong)容量變為3,000mAh。容量是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)在(zai)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)之前可(ke)(ke)以吸取電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流多長時(shi)間的(de)量度。

考慮到(dao)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)輸(shu)(shu)出(chu)和機(ji)(ji)身重量(liang)(liang)(liang)之間(jian)的(de)(de)平衡，這是(shi)可(ke)(ke)以(yi)(yi)提(ti)升(sheng)的(de)(de)最佳電(dian)(dian)(dian)(dian)(dian)池(chi)容(rong)量(liang)(liang)(liang)。這是(shi)因(yin)為隨著(zhu)容(rong)量(liang)(liang)(liang)的(de)(de)增(zeng)加，飛(fei)(fei)(fei)行時間(jian)自然增(zeng)加，但電(dian)(dian)(dian)(dian)(dian)池(chi)尺(chi)寸增(zeng)加，重量(liang)(liang)(liang)增(zeng)加。這是(shi)選(xuan)擇。市(shi)場(chang)上的(de)(de)無(wu)人(ren)機(ji)(ji)正在銷售(shou)帶(dai)有電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)和相應型(xing)號重量(liang)(liang)(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)。（所(suo)(suo)以(yi)(yi)相同數量(liang)(liang)(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)飛(fei)(fei)(fei)行時間(jian)幾乎相同）放(fang)電(dian)(dian)(dian)(dian)(dian)率(lv)(lv)C值是(shi)電(dian)(dian)(dian)(dian)(dian)池(chi)放(fang)電(dian)(dian)(dian)(dian)(dian)速率(lv)(lv)的(de)(de)量(liang)(liang)(liang)度(du)。這是(shi)因(yin)為放(fang)電(dian)(dian)(dian)(dian)(dian)率(lv)(lv)乘以(yi)(yi)容(rong)量(liang)(liang)(liang)是(shi)電(dian)(dian)(dian)(dian)(dian)池(chi)可(ke)(ke)以(yi)(yi)得出(chu)最大(da)輸(shu)(shu)出(chu)。例如(ru)，如(ru)果您的(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)壓為14.8V（4S）1,600mAh 95C，則可(ke)(ke)以(yi)(yi)輸(shu)(shu)出(chu)高(gao)達1,600 X 95 = 152,000mA（152A）的(de)(de)電(dian)(dian)(dian)(dian)(dian)流。您可(ke)(ke)能知道，常見的(de)(de)四軸飛(fei)(fei)(fei)行器(qi)賽車無(wu)人(ren)機(ji)(ji)有四個使用(yong)無(wu)刷電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)設置。當每個設置的(de)(de)所(suo)(suo)需(xu)功(gong)率(lv)(lv)為20A時，需(xu)要80A才能使電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)通(tong)過設置。然后，使用(yong)上述電(dian)(dian)(dian)(dian)(dian)池(chi)，您可(ke)(ke)以(yi)(yi)在緩沖狀(zhuang)態下(xia)完全提(ti)供設置所(suo)(suo)需(xu)的(de)(de)最大(da)功(gong)率(lv)(lv)。（當然，不(bu)僅(jin)設置還有攝像頭，FC，蜂鳴器(qi)，LED等，也會取電(dian)(dian)(dian)(dian)(dian)，但忽(hu)略它(ta)，因(yin)為它(ta)與通(tong)過設置輸(shu)(shu)送到(dao)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)功(gong)率(lv)(lv)相比是(shi)少量(liang)(liang)(liang)的(de)(de)）但是(shi)，假設飛(fei)(fei)(fei)行時剩余電(dian)(dian)(dian)(dian)(dian)量(liang)(liang)(liang)下(xia)降到(dao)一半（800mAh）。

然(ran)后電池(chi)(chi)輸出(chu)為(wei)800 X 95 = 76,000 mA（76 A）。也就是說，即使(shi)剩余電池(chi)(chi)容量(liang)(liang)減少(shao)到一(yi)半，設置的(de)(de)最(zui)大(da)電源也變(bian)得困難，并(bing)且電動(dong)(dong)機(ji)的(de)(de)最(zui)大(da)輸出(chu)不能增加(jia)。如(ru)果(guo)無人(ren)(ren)機(ji)沒有(you)(you)達到提升重量(liang)(liang)的(de)(de)最(zui)小功率(lv)，它們將無法再飛行。換句(ju)話說，當(dang)你(ni)(ni)飛行無人(ren)(ren)機(ji)時(shi)，你(ni)(ni)很少(shao)會(hui)讓(rang)(rang)電池(chi)(chi)完全放(fang)電。如(ru)果(guo)輸出(chu)變(bian)低并(bing)且在(zai)(zai)電池(chi)(chi)耗盡之(zhi)前無法讓(rang)(rang)無人(ren)(ren)機(ji)繼續飛，則會(hui)有(you)(you)一(yi)些(xie)剩余電量(liang)(liang)。（對于(yu)傳感(gan)器(qi)無人(ren)(ren)機(ji)，當(dang)剩下四分之(zhi)一(yi)的(de)(de)電池(chi)(chi)時(shi)，有(you)(you)許多型號(hao)會(hui)自動(dong)(dong)激活“返回原(yuan)點(dian)”功能）當(dang)然(ran)，如(ru)果(guo)你(ni)(ni)在(zai)(zai)那種狀態下讓(rang)(rang)無人(ren)(ren)機(ji)離開，你(ni)(ni)可(ke)以完全放(fang)電，但沒有(you)(you)人(ren)(ren)會(hui)這樣做，這樣做不利(li)于(yu)電池(chi)(chi)壽命(ming)。由于(yu)電池(chi)(chi)壽命(ming)的(de)(de)緣故，我必須(xu)告訴(su)你(ni)(ni)如(ru)何管理(li)電池(chi)(chi)。

3.電池管(guan)理注意事項(xiang)

電池(chi)電壓(ya)(ya)為每節電池(chi)3.7V，但當(dang)它被緩沖時(shi)，它會(hui)上升到(dao)4.2V，當(dang)它放電時(shi)它會(hui)下降到(dao)3.3V。但是，如果電壓(ya)(ya)長(chang)時(shi)間(jian)高(gao)于或低于參考(kao)電壓(ya)(ya)，則可能導(dao)致(zhi)電池(chi)鼓包或變得無法使用。專家表示，保持3.5V至3.85V始終有(you)助于延長(chang)電池(chi)壽命。

那么你如何實現延長電池壽命的夢想？

最(zui)容(rong)易想到的(de)是(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)時間(jian)(jian)。如果電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)以(yi)接近每(mei)(mei)個電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)4.2V的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)存(cun)儲(chu)，則電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)可(ke)能會(hui)鼓包(bao)。所(suo)以(yi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)對于(yu)“飛行(xing)(xing)前一(yi)天”是(shi)有益的(de)。當然最(zui)好(hao)在飛行(xing)(xing)前做。但(dan)(dan)(dan)是(shi)，我不(bu)知道(dao)(dao)玩具的(de)迷你(ni)(ni)無(wu)(wu)人機(ji)(ji)，但(dan)(dan)(dan)對于(yu)4芯傳感(gan)器無(wu)(wu)人機(ji)(ji)，需要幾個小時才能充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，但(dan)(dan)(dan)由于(yu)它與(yu)飛行(xing)(xing)時間(jian)(jian)相(xiang)匹配而無(wu)(wu)法充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。當你(ni)(ni)飛行(xing)(xing)時，你(ni)(ni)會(hui)想要在電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)量低于(yu)1/4之前完成飛行(xing)(xing)。順便說(shuo)一(yi)下(xia)……即(ji)使我們(men)(men)試(shi)圖管(guan)理它，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)壽(shou)命(ming)也會(hui)縮短(duan)。只要它不(bu)適合(he)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)之間(jian)(jian)的(de)平(ping)衡(heng)(heng)。據說(shuo)無(wu)(wu)人機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)在最(zui)小電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)單(dan)(dan)元(yuan)中使用3.7V并連接多個串聯(lian)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)。然而，即(ji)使我們(men)(men)的(de)普通充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器能夠(gou)在充(chong)(chong)滿電(dian)(dian)(dian)(dian)(dian)時關(guan)閉充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)以(yi)防止過度充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，但(dan)(dan)(dan)要知道(dao)(dao)所(suo)有電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)都是(shi)同(tong)等緩沖的(de)還不(bu)夠(gou)聰明。 也就是(shi)說(shuo)，盡管(guan)緩沖時的(de)總電(dian)(dian)(dian)(dian)(dian)壓(ya)與(yu)緩沖電(dian)(dian)(dian)(dian)(dian)壓(ya)相(xiang)同(tong)，但(dan)(dan)(dan)每(mei)(mei)個單(dan)(dan)元(yuan)的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)可(ke)以(yi)不(bu)同(tong)。存(cun)在電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)破(po)裂并膨(peng)脹(zhang)超(chao)過4.2V的(de)風險(xian)。為(wei)了防止這種危(wei)險(xian)，使用“電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)平(ping)衡(heng)(heng)器”或“平(ping)衡(heng)(heng)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器”，平(ping)衡(heng)(heng)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器在檢查(cha)(cha)每(mei)(mei)個電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)同(tong)時，均勻地為(wei)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)供電(dian)(dian)(dian)(dian)(dian)。一(yi)旦您將無(wu)(wu)人機(ji)(ji)排空，您還可(ke)以(yi)插(cha)入天平(ping)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器以(yi)檢查(cha)(cha)哪些電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)耗盡更多。因(yin)此，如果你(ni)(ni)有20到30個電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，你(ni)(ni)可(ke)以(yi)說(shuo)平(ping)衡(heng)(heng)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器幾乎(hu)是(shi)必要的(de)。

如果(guo)您(nin)(nin)(nin)使(shi)用的(de)是低成本(ben)傳(chuan)感器無人(ren)機，或(huo)(huo)者如果(guo)您(nin)(nin)(nin)使(shi)用的(de)是玩具電池超過2秒，您(nin)(nin)(nin)可(ke)能(neng)會對購買充電器猶豫不決(jue)。即(ji)使(shi)您(nin)(nin)(nin)有(you)過充電保護(hu)裝(zhuang)置，如果(guo)關閉(bi)電池平衡，也(ye)可(ke)能(neng)導致爆(bao)炸(zha)或(huo)(huo)火災。

無人機電池

4.電池兼容性

最后，我們來(lai)看(kan)看(kan)電(dian)池兼(jian)容性。電(dian)池兼(jian)容性也(ye)是一(yi)個(ge)重要(yao)因素(su)。參數(shu)規格匹(pi)配時，就可以得到了額外的(de)一(yi)個(ge)電(dian)池可與其他(ta)無人機(ji)進行共享。當你看(kan)電(dian)池兼(jian)容性時，只(zhi)需查(cha)看(kan)三個(ge)參數(shu)規格。

電壓

您只能在規(gui)格中(zhong)看到電(dian)(dian)壓。電(dian)(dian)壓必(bi)須(xu)完全匹配。使用(yong)3.7V 1s電(dian)(dian)池(chi)的(de)無(wu)(wu)人(ren)機僅適用(yong)于1s電(dian)(dian)池(chi)，而帶有7.4v 2s電(dian)(dian)池(chi)的(de)無(wu)(wu)人(ren)機應僅使用(yong)2s電(dian)(dian)池(chi)。不必(bi)擔心(xin)放(fang)電(dian)(dian)率(lv)。放(fang)電(dian)(dian)率(lv)是電(dian)(dian)池(chi)的(de)性(xing)能，所以有些人(ren)關心(xin)它，但1s 使用(yong)容(rong)量約100~300mah的(de)電(dian)(dian)池(chi)，所以輸出就在那(nei)里。此外(wai)，玩(wan)具無(wu)(wu)刷電(dian)(dian)機不需要(yao)設置或功(gong)耗。

形狀，大小，重量

我不(bu)(bu)知道是否對規(gui)范(fan)中的容量有(you)(you)任何疑(yi)問。如果電池容量太大(da)，則存在因(yin)電池體積龐(pang)大(da)而無(wu)(wu)法裝入有(you)(you)些無(wu)(wu)人機(ji)。或者(zhe)也許是因(yin)為重(zhong)量不(bu)(bu)同，有(you)(you)可能導(dao)致無(wu)(wu)人機(ji)續航減少。例如迷你無(wu)(wu)人機(ji)的飛行重(zhong)量會有(you)(you)所(suo)不(bu)(bu)同，甚至幾(ji)克差異，還(huan)有(you)(you)一(yi)些微型無(wu)(wu)人機(ji)具有(you)(you)細長(chang)的電池形狀，有(you)(you)些是短而厚(hou)的，各種(zhong)各樣。

連接器

決定(ding)性地為無人(ren)機提供(gong)電(dian)池(chi)的(de)(de)電(dian)線上的(de)(de)連接器的(de)(de)形(xing)狀應該是相同的(de)(de)。廣泛使用(yong)的(de)(de)無人(ren)機電(dian)池(chi)連接器的(de)(de)形(xing)狀，現在市(shi)面上也有(you)存在。
