1. Direct charge point protection point voltage: Direct charge imatchedwanso chargement charge, yomwe ndi yachangu.Nthawi zambiri, mphamvu ya batri ikatsika, batire imayimbidwa ndi magetsi okwera kwambiri komanso voteji yayikulu.Komabe, pali malo owongolera, omwe amatchedwanso chitetezo Mfundo ndi mtengo womwe uli pamwambapa.Mphamvu yamagetsi yamagetsi ya batri ikakwera kuposa mphamvu zodzitchinjirizazi panthawi yolipirira, kuyimitsa kwachindunji kuyenera kuyimitsidwa.Mphamvu yamagetsi yotchingira pachindunji nthawi zambiri imakhala "voltage yodzitchinjiriza", ndipo voteji ya batire singakhale yokwera kuposa malo otetezedwawa panthawi yolipiritsa, apo ayi izi zimapangitsa kuti batire ichuluke ndikuwononga batire.
2. Equalization charge control point voltage: Kumalizidwa kwachindunji, batire nthawi zambiri imasiyidwa kwakanthawi ndi wowongolera kuti alole kuti magetsi ake azitsika mwachilengedwe.Ikatsikira ku mtengo wa "recovery voltage", idzalowa muyeso yofanana.Chifukwa chiyani kupanga mtengo wofanana?Ndiye kuti, kumalizidwa kwachindunji kutha, pakhoza kukhala mabatire amtundu wina "otsalira kumbuyo" (voltage yotsiriza ndiyotsika).Kuti mukoke mamolekyu awa m'mbuyo ndikupanga ma voltages onse a batri, ndikofunikira kufananiza voteji yayikulu ndi voteji yapakatikati.Kenako lipirani kwakanthawi kochepa, zitha kuwoneka kuti zomwe zimatchedwa kuti equalization charge, ndiye "malipiro olinganiza".Nthawi yolipiritsa yofananira siyenera kukhala yayitali kwambiri, nthawi zambiri mphindi zochepa mpaka mphindi khumi, ngati nthawiyo ili yayitali kwambiri, ingakhale yovulaza.Pa makina ang'onoang'ono okhala ndi batire imodzi kapena awiri, kulipiritsa kofanana sikufunikira kwenikweni.Choncho, zounikira magetsi mumsewu nthawi zambiri sakhala ndi ndalama zofanana, koma magawo awiri okha.
3. Voltage yowongolera yoyandama: Nthawi zambiri, mtengo wofananira ukamalizidwa, batire imasiyidwanso kuti iyime kwakanthawi, kuti voteji ya terminal igwere mwachilengedwe, ndipo ikatsikira pa "voltage yosamalira", imalowa m'malo oyandama.Pakadali pano, PWM imagwiritsidwa ntchito.(zonse ziwiri pulse width modulation) njira, yofanana ndi "kuthamangitsa" (ndiko kuti, kuyendetsa pang'ono pakalipano), onjezerani pang'ono mphamvu ya batri ikachepa, ndipo onjezerani pang'ono pamene yatsika, imodzi ndi imodzi kuti muteteze Kutentha kwa batri kuchokera kupitiliza kukwera Kwambiri, zomwe ndi zabwino kwambiri kwa batire, chifukwa kutentha kwamkati kwa batri kumakhudza kwambiri kuyitanitsa ndi kutulutsa.M'malo mwake, njira ya PWM idapangidwa makamaka kuti ikhazikitse voliyumu ya batire, ndikuchepetsa kuyitanitsa kwa batri posintha kuchuluka kwa pulse.Iyi ndi njira yasayansi yoyendetsera ndalama.Makamaka, kumapeto kwa kulipiritsa, mphamvu yotsalira (SOC) ya batire ndi> 80%, mphamvu yolipiritsa iyenera kuchepetsedwa kuti mupewe kutulutsa mpweya wambiri (oksijeni, haidrojeni ndi mpweya wa asidi) chifukwa chakuchulukirachulukira.
4. Kuyimitsa mphamvu yachitetezo chambiri: Izi ndizosavuta kumvetsetsa.Kutulutsidwa kwa batire sikungakhale kotsika kuposa mtengo uwu, womwe ndi muyezo wadziko lonse.Ngakhale opanga mabatire amakhalanso ndi magawo awo otetezera (muyezo wamakampani kapena mulingo wamakampani), amayenera kuyandikirabe muyezo wadziko pomaliza.Tiyenera kudziwa kuti, pofuna chitetezo, nthawi zambiri 0.3v imawonjezedwa mopanda kutulutsa mphamvu yamagetsi ya batri ya 12V ngati chiwongolero cha kutentha kapena kuwongolera zero-point drift ya dera lowongolera, kuti kutulutsa kopitilira muyeso. Chitetezo cha batire ya 12V ndi: 11.10v, ndiye Mphamvu yoteteza kwambiri ya 24V system ndi 22.20V.
