Mabatire a lithiamu amafunika kutetezedwa.Ngati ndi18650 lithiamu batirealibe bolodi lachitetezo, choyamba, simukudziwa momwe batire ya lithiamu imayimbidwira kutali, ndipo chachiwiri, sichikhoza kuimbidwa popanda bolodi lachitetezo, chifukwa bolodi lachitetezo liyenera kulumikizidwa ndi batri ya lithiamu yokhala ndi mawaya awiri.Musaganize kuti khalidwe la batri ya lithiamu yomwe mudagula ndi yabwino popanda bolodi la chitetezo, koma ngati zitenga nthawi yaitali, mavuto osiyanasiyana adzachitika.

Lifiyamu batire chitetezo bolodi ndi kulipiritsa ndi kutulutsa chitetezo cha mndandanda lithiamu batire paketi, amene angathe kuonetsetsa kuti voteji kusiyana pakati mabatire ndi zosakwana mtengo anapereka, ndipo akhoza kukwaniritsa bwino batire aliyense mu batire. paketi, potero kuwongolera bwino mndandanda wolumikizira Kuwongolera pamachitidwe opangira.Pa nthawi yomweyo, akhoza kudziwa overvoltage, overcharge, overdischarge, dera lalifupi ndi kutenthedwa kwa batire opangidwa ndi aliyense lifiyamu batire malo kuwotcherera mu batire paketi kuteteza ndi kuwonjezera moyo batire.Chitetezo chapansi pamagetsi chingalepheretse selo lililonse kuti lisawonongeke ndi kutuluka mopitirira muyeso panthawi yotulutsa.

1. Kusankha bolodi lachitetezo ndikulipiritsa ndi kutulutsa nkhani zogwiritsa ntchito
(Deta ndi yalithiamu iron phosphate batire, mfundo ya batire wamba 3.7v ndi yofanana, koma deta ndi yosiyana)

Cholinga cha bolodi lachitetezo ndikuteteza batire kuti lisapitirire mochulukira komanso kuthamangitsidwa, kuletsa kuchuluka kwamagetsi kuti lisawononge batire, komanso kuwongolera mphamvu ya batri ikamanga bwino (kuthekera kolumikizana nthawi zambiri kumakhala kochepa, kotero ngati pali bolodi yodzitchinjiriza ya batri yodziyimira payokha, ndizovuta kwambiri kulinganiza, ndipo palinso matabwa oteteza omwe amayenderana mumtundu uliwonse, ndiye kuti, kuwongolera kumachitika kuyambira pachiyambi cha kulipiritsa, zomwe zikuwoneka kuti ndizosowa).

Kwa moyo wa batire paketi, tikulimbikitsidwa kuti voteji yothamangitsa batire isapitirire 3.6v nthawi iliyonse, zomwe zikutanthauza kuti chitetezo chachitetezo cha bolodi sichili chokwera kuposa 3.6v, ndipo voteji yoyenera ikuyenera kukhala 3.4v-3.5v (selo lililonse la 3.4v laperekedwa kuposa 99 % Battery, imatanthawuza dziko lokhazikika, voteji idzawonjezeka pamene ikuyitanitsa ndi mkulu wamakono).Mphamvu yamagetsi yoteteza kutulutsa kwa batri nthawi zambiri imakhala pamwamba pa 2.5v (pamwamba pa 2v sivuto lalikulu, nthawi zambiri palibe mwayi wogwiritsa ntchito mphamvu zake zonse, kotero izi sizokwera).

2. Ma voliyumu ovomerezeka ovomerezeka a charger (gawo lomaliza lolipiritsa likhoza kukhala njira yamagetsi yamagetsi yosalekeza) ndi 3.5 * kuchuluka kwa zingwe, monga za 56v kwa zingwe 16.Nthawi zambiri kulipira kutha kudulidwa pafupifupi 3.4v pa selo (makamaka yoyendetsedwa mokwanira), kuti moyo wa batri ukhale wotsimikizika, koma chifukwa bolodi lachitetezo silinayambe kulinganiza, ngati chigawo cha batri chili ndi kudziletsa kwakukulu. , idzachita monga gulu lonse pakapita nthawi Mphamvu imachepa pang'onopang'ono.Chifukwa chake, ndikofunikira kulipiritsa batire iliyonse mpaka 3.5v-3.6v pafupipafupi (mwachitsanzo sabata iliyonse) ndikuyisunga kwa maola angapo (malinga ngati avareji ndi yayikulu kuposa voliyumu yoyambira yofananira), ndikudziyimitsa kwambiri, nthawi yayitali yofananira idzatenga, ndipo kudziletsa Kukula kwa ma cell ndizovuta kulinganiza ndipo kuyenera kuchotsedwa.Chifukwa chake posankha bolodi loteteza, yesani kusankha chitetezo cha 3.6v overvoltage, ndikuyamba kufananiza mozungulira 3.5v.(Zambiri zachitetezo chochulukirapo pamsika chili pamwamba pa 3.8v, ndipo mgwirizano umayamba pamwamba pa 3.6v).M'malo mwake, kusankha voteji yoyenera yoyambira ndikofunikira kwambiri kuposa voteji yachitetezo, chifukwa voteji yayikulu imatha kusinthidwa ndikusintha malire amagetsi a charger (ndiko kuti, bolodi lodzitchinjiriza nthawi zambiri limakhala lilibe mwayi wochita chitetezo champhamvu kwambiri. ), koma ngati magetsi oyenerera ali apamwamba, paketi ya batri ilibe mwayi wokwanira (pokhapokha Kuthamanga kwamagetsi kuli kwakukulu kuposa mphamvu yamagetsi, koma izi zimakhudza moyo wa batri), selo la batri lidzachepa pang'onopang'ono chifukwa cha kudziletsa. mphamvu (selo yabwino yokhala ndi kudziletsa kwa 0 kulibe).

3. Kutulutsa kosalekeza komweku kwa bolodi lachitetezo.Ichi ndiye chinthu choyipa kwambiri kuyankhapo.Chifukwa mphamvu zochepetsera pano za bolodi lachitetezo zilibe tanthauzo.Mwachitsanzo, ngati mulola chubu cha 75nf75 kuti chipitirire kupitirira 50a panopa (panthawiyi, mphamvu yotenthetsera ili pafupi 30w, osachepera awiri 60w pamndandanda pa bolodi lomwelo la doko), bola ngati pali kutentha kokwanira kuti zisawonongeke. kutentha, palibe vuto.Itha kusungidwa pa 50a kapena kupitilira apo osawotcha chubu.Koma simunganene kuti bolodi lotetezali limatha kukhala 50a pano.Chifukwa mbale zodzitchinjiriza za aliyense zimayikidwa mu bokosi la batri pafupi kwambiri ndi batire, kapena kutseka.Chifukwa chake kutentha kotereku kumatenthetsa batire ndikuwotcha.Vuto ndiloti kutentha kwakukulu ndi mdani wakupha wa batri.

Choncho, malo ogwiritsira ntchito bolodi lachitetezo amasankha momwe angasankhire malire omwe alipo (osati mphamvu zomwe zilipo panopa).Ngati bolodi lachitetezo likuchotsedwa mu bokosi la batri, ndiye kuti pafupifupi bolodi lililonse lachitetezo lomwe lili ndi choyatsira kutentha limatha kuthana ndi 50a mosalekeza kapena kupitilira apo (panthawiyi, mphamvu ya bolodi yokhayo imaganiziridwa, ndipo palibe chifukwa chodera nkhawa. kukwera kwa kutentha komwe kumayambitsa kuwonongeka kwa ma cell).Tiye tikambirane za chilengedwe chomwe aliyense amagwiritsa ntchito, chomwe chili m'malo otsekeka ngati batire.Panthawiyi, mphamvu yowonjezera yowonjezera ya bolodi yotetezera imayang'aniridwa bwino pansi pa 10w (ngati ndi bolodi laling'ono lotetezera, likufunika 5w kapena zochepa, ndipo bolodi lalikulu la chitetezo likhoza kukhala loposa 10w, chifukwa lili ndi kutentha kwabwino. kutaya ndi kutentha sikudzakhala kokwera kwambiri).Zomwe zili zoyenera, nthawi zonse zimalimbikitsidwa Pamene kutentha kwakukulu kwa bolodi lonse sikudutsa madigiri 60 (zabwino kwambiri pansi pa madigiri 50).Mwachidziwitso, kutsika kwa kutentha kwa bolodi lachitetezo, kumakhala bwino, komanso kumakhudza ma cell.

4. Kusiyanitsa pakati pa bolodi la doko lomwelo ndi bolodi la doko losiyana: bolodi lomwelo ndilo mzere womwewo wa kulipiritsa ndi kutulutsa, ndipo zonse zolipiritsa ndi kutulutsa zimatetezedwa.

Bolodi la doko losiyana ndi lodziyimira pawokha pamzere wolipiritsa ndi mzere wotulutsa.Doko lolipiritsa limangoteteza kuti lisachuluke mukalipira, ndipo silimateteza ngati litulutsidwa padoko lolipiritsa (koma limatha kutulutsa kwathunthu, koma mphamvu yaposachedwa ya doko yothamangitsa nthawi zambiri imakhala yaying'ono).Doko lotulutsa limateteza kutulutsa kwambiri panthawi yotulutsa.Ngati kulipiritsa kuchokera padoko lotayira, kulipiritsa kwambiri sikutetezedwa (kotero kubweza kwa ecpu kumatha kugwiritsidwa ntchito pama doko osiyanasiyana. Ndipo mtengo wakenso ndi wocheperapo kuposa mphamvu yomwe wagwiritsidwa ntchito, chifukwa chake musade nkhawa zakuchulukira batire chifukwa chakubweza mobwerera.

Kuwerengera kuchuluka kwamphamvu kwagalimoto yanu, sankhani batire yokhala ndi mphamvu kapena mphamvu yoyenera yomwe ingakwaniritse izi mosalekeza ndipo kutentha kumayendetsedwa.Zing'onozing'ono kukana kwamkati kwa bolodi lachitetezo, ndibwino.Chitetezo cha boardboard overcurrent chitetezo chimangofunika chitetezo chachifupi komanso chitetezo china chogwiritsa ntchito mwachilendo.
Chidule: Kugwiritsa ntchito mabatire a lithiamu kuyenera kuwongolera kutentha kwambiri (kukwera kwa kutentha komwe kumachitika chifukwa cha kutulutsa kwakanthawi kochepa kapena komwe kumachitika chifukwa cha chilengedwe), ndikuwongolera kuchuluka kwamagetsi othamangitsa komanso kutulutsa kocheperako (kuti kumalizike ndi bolodi lachitetezo ndi charger. ).Ndi bwino kusunga batire pa voteji nsanja (za 3.25-3.3v kwa lithiamu chitsulo phosphate) pamene si ntchito.

Kuchepetsa kukana kwamkati kwa bolodi lachitetezo, kumakhala bwino, komanso kutsika kwapakati, kumatenthetsa pang'ono.Malire apano a bolodi lachitetezo amatsimikiziridwa ndi kukana kwa sampuli zamkuwa, koma kuthekera kosalekeza kwapano kumatsimikiziridwa ndi mos (chifukwa kukana kwamkati kwa mos kumatsimikizira kukwera kwa kutentha).
