Zinthu 6 Zofunika Zotetezera Zomwe Muyenera Kuzifufuza Mukamagula Mabatire Amagetsi Amphamvu mu 2023

1. Chitetezo chacharge

Chitetezo chacharge chimatanthawuza: mabatire a lifiyamu akamalipira, mphamvu yamagetsi ikukwera kupitirira malire oyenera, idzabweretsa kusatsimikizika ndi ngozi. Ntchito yoteteza mochulukira ya bolodi yoteteza ndikuwunika mphamvu ya batri munthawi yeniyeni, ndikudula magetsi pomwe kulipiritsa kukafika pachimake chamtundu wamagetsi otetezeka, kulepheretsa kuti magetsi asapitirire kukwera, motero kusewera chitetezo ntchito.
Ntchito yoteteza mochulukira: Ikalipira, bolodi yoteteza imayang'anira voteji ya chingwe chilichonse cha paketi ya batri munthawi yeniyeni, bola mphamvu imodzi yamagetsi ikafika pamtengo wotetezedwa (voltage yowonjezereka ya ternary ndi 4.25V ± 0.05 V, ndi kusakhulupirika overcharge voteji wa LiFePO4.75V ± 0.05V), bolodi adzadula magetsi, ndi gulu lonse la mabatire lifiyamu adzasiya kulipiritsa.

2.Kuteteza kwambiri kutulutsa

Kutetezedwa kopitilira muyeso kumatanthawuza: mabatire a lithiamu pakutulutsa, ndikutsika kwa voteji, ngati magetsi onse atulutsidwa kuti atope, zinthu zama mankhwala mkati mwa batire ya lithiamu zidzataya ntchito, zomwe zimapangitsa kuti azilipira mphamvu kapena kuchepa kwa mphamvu. Ntchito yoteteza kutulutsa kopitilira muyeso ya bolodi yodzitchinjiriza ndikuwunika voteji ya batire paketi munthawi yeniyeni, ndikudula magetsi mukatsitsa mpaka pansi kwambiri.mphamvu ya batri, kulepheretsa kuti magetsi asapitirire kugwa, kuti agwire ntchito yoteteza.

Ntchito yoteteza mochulukirachulukira: Ikatulutsa, bolodi yodzitchinjiriza imayang'anira voteji ya chingwe chilichonse cha paketi ya batri munthawi yeniyeni, bola mphamvu imodzi yazingwe ikafika pamtengo wotetezedwa kwambiri (voltage yopitilira-discharge ya ternary ndi 2.7V ± 0.1V, ndi kusakhulupirika pa-kutulutsa voteji wa LiFePO4 ndi 2.2V ± 0.1V), bolodi adzadula magetsi, ndi gulu lonse la mabatire lifiyamu adzasiya kutulutsa.

3.Overcurrent chitetezo

Chitetezo cha overcurrent chimatanthawuza: mabatire a lithiamu mu mphamvu yonyamula katundu, zamakono zidzasintha ndi kusintha kwa magetsi ndi mphamvu, pamene panopa ndipamwamba kwambiri, n'zosavuta kuwotcha bolodi la chitetezo, batire kapena zipangizo. Ntchito yachitetezo chopitilira muyeso ya board yoteteza ndikuwunika momwe batire likuyendera munthawi yeniyeni panthawi yolipiritsa ndi kutulutsa, ndipo mphamvu ikapitilira kuchuluka kwa chitetezo, imadula njira yomwe ikudutsa, kuletsa chisanu.m kuwononga mabatire kapena zida, kuti athe kuteteza.

Chitetezo cha overcurrent: pamalipiritsa ndi kutulutsa, gulu lachitetezo lidzayang'anira batire yomwe ilipo mu nthawi yeniyeni, bola ikafika pamtengo wotetezedwa, gulu lachitetezo lidzadula magetsi, ndi gulu lonse la mabatire a lithiamu. adzasiya kulipiritsa ndi kutulutsa.

4.high / low kutentha chitetezo

Chitetezo chowongolera kutentha: Chowunikira chowongolera kutentha cha bolodi lachitetezo cha hardware chimawotcherera ku bolodi lamkati la bolodi lachitetezo ndipo silingatsegulidwe. Kufufuza kowongolera kutentha kumatha kuwunika kusintha kwa kutentha kwa paketi ya batri kapena malo ogwirira ntchito munthawi yeniyeni, pamene kutentha koyang'aniridwa kumapitilira mtengo wokhazikika (kusungidwa kwa chitetezo cha kutentha kwa hardware: kulipira -20 ~ 55 ℃, kutulutsa -40 ~ 75 ℃, yomwe ingasinthidwe molingana ndi zofuna za kasitomala, ndipo kasitomala sangathe kuziyika yekha), paketi ya batri idzachotsedwa pa kulipiritsa ndi kutulutsa, ndipo paketi ya batri ikhoza kupitiriza kuimbidwa ndi kutulutsidwa pamene kutentha kuli kutentha. kubwezeretsedwa pamlingo woyenerera kuti agwire ntchito yoteteza.

5.chitetezo chokwanira
Kufanana kwapang'onopang'ono kumatanthawuza: pakakhala kusagwirizana kwamagetsi pakati pa zingwe za mabatire, bolodi loteteza lisintha ma voliyumu a chingwe chilichonse kuti chisasunthike pakuyitanitsa p.rosi.

Ntchito yofananira: Gulu lodzitchinjiriza likawona kusiyana kwamagetsi pakati pa batire ya lithiamu ndi zingwe, ikamalipiritsa, zingwe zokwera voteji zimafika pamtengo wofanana (ternary: 4.13V, LiFe3.525V), kutulutsa (kuwononga) ndi chopinga chofanana ndi wapano wa pafupifupi 30-35mA, ndi zingwe zina zotsika voteji zimapitilira kulipira. Pitirizani mpaka kudzaza.

6.chitetezo chachifupi chozungulira (kuzindikira zolakwika + chitetezo chotsutsana ndi reverse)
Kuzungulira kwachidule kumatanthauza: dera lalifupi limapangidwa pamene ma terminals abwino ndi oipa a batri alumikizidwa kwambirictly popanda katundu. Dera lalifupi lidzabweretsa kuwonongeka kwa batri, zida ndi zina zotero.

Ntchito yachitetezo chafupipafupi: batri ya lithiamu mosadziwa chifukwa chafupikitsa (monga kulumikiza mzere wolakwika, kutenga mzere wolakwika, madzi ndi zifukwa zina), bolodi yoteteza idzakhala munthawi yochepa kwambiri (masekondi 0.00025) , kudula njira yamagetsi, kuti igwire ntchito yoteteza.
