Chiyambi
Maselo a lithiamu a LiFePO4Zakhala zodziwika bwino m'magwiritsidwe osiyanasiyana m'zaka zaposachedwa chifukwa chakuti ndi imodzi mwa njira zolimba kwambiri komanso zokhalitsa za batri zomwe zilipo. Zitha kukhala zaka khumi kapena kuposerapo ngati zisamalidwa bwino. Tengani kamphindi kuti muwerenge malangizo awa kuti muwonetsetse kuti mukupeza ntchito yayitali kwambiri kuchokera ku ndalama zomwe mwayika pa batri.

Langizo 1: Musamayike mphamvu yochulukirapo pa foni yanu!
Zomwe zimayambitsa kulephera kwa maselo a LiFePO4 msanga ndi kukweza mphamvu ndi kutulutsa mphamvu mopitirira muyeso. Ngakhale kamodzi kokha kangawononge selo kwamuyaya, ndipo kugwiritsa ntchito molakwika koteroko sikuthandiza chitsimikizo. Dongosolo Loteteza Batri likufunika kuti zitsimikizire kuti selo lililonse lomwe lili mu paketi yanu silingathe kupita kunja kwa mphamvu yake yogwiritsira ntchito,
Pankhani ya LiFePO4 Chemistry, mphamvu yokwanira ndi 4.2V pa selo iliyonse, ngakhale kuti ndi bwino kuti mulipire mpaka 3.5-3.6V pa selo iliyonse, pali mphamvu yowonjezera yochepera 1% pakati pa 3.5V ndi 4.2V.

Kuchaja kwambiri kumayambitsa kutentha mkati mwa selo ndipo kuchaja kwambiri kwa nthawi yayitali kapena kopitirira muyeso kumatha kuyambitsa moto. LIAO siili ndi udindo pa kuwonongeka kulikonse komwe kumachitika chifukwa cha moto wa batri.

Kuchaja mopitirira muyeso kungachitike chifukwa cha.

★Kusowa kwa njira yoyenera yotetezera batri

★ Vuto la chitetezo cha batri yopatsirana matenda

★Kuyika kolakwika kwa dongosolo loteteza batri

LIAO siitenga udindo pa kusankha kapena kugwiritsa ntchito njira yotetezera batri.

Kumapeto ena a sikelo, kutulutsa mphamvu mopitirira muyeso kungayambitsenso kuwonongeka kwa maselo. BMS iyenera kuchotsa katundu ngati maselo ena akuyandikira opanda kanthu (osakwana 2.5V). Maselo akhoza kuwonongeka pang'ono pansi pa 2.0V, koma nthawi zambiri amatha kubwezeretsedwa. Komabe, maselo omwe amayendetsedwa ku ma voltages olakwika amawonongeka kwambiri moti sadzachiranso.

Pa mabatire a 12v, kugwiritsa ntchito njira yochepetsera mphamvu yamagetsi kumatenga malo a BMS poletsa mphamvu yamagetsi ya batri yonse kuti isapitirire 11.5v, palibe kuwonongeka kwa maselo komwe kungachitike. Kumbali ina, kuyitanitsa kosapitirira 14.2v, palibe selo lomwe liyenera kuyitanitsa mphamvu yochulukirapo.

Langizo lachiwiri: Tsukani ma terminal anu musanayike

Ma terminal omwe ali pamwamba pa mabatire amapangidwa ndi aluminiyamu ndi mkuwa, zomwe pakapita nthawi zimapanga oxide layer ikayikidwa mumlengalenga. Musanayike ma cell interconnectors anu ndi ma BMS modules, yeretsani ma batire bwinobwino ndi burashi ya waya kuti muchotse oxidation. Ngati mukugwiritsa ntchito ma barre copper cell interconnectors, awa ayeneranso kuthana nawo. Kuchotsa oxide layer kudzathandiza kwambiri conduction ndikuchepetsa kutentha komwe kumapangidwa pa terminal. (Nthawi zambiri, kutentha komwe kumapangidwa pa ma terminals chifukwa cha conduction yosakwanira kwadziwika kuti kumasungunula pulasitiki yozungulira ma terminals ndikuwononga ma BMS modules!)

Langizo 3: Gwiritsani ntchito zida zoyenera zoyikira

Maselo a Winston omwe amagwiritsa ntchito ma terminal a M8 (90Ah ndi mmwamba) ayenera kugwiritsa ntchito mabolts aatali a 20mm. Maselo omwe ali ndi ma terminal a M6 (60Ah ndi pansi) ayenera kugwiritsa ntchito mabolts a 15mm. Ngati mukukayika, yesani kuya kwa ulusi m'maselo anu ndikuwonetsetsa kuti mabolts ali pafupi koma osagunda pansi pa dzenjelo. Kuyambira pamwamba mpaka pansi muyenera kukhala ndi chotsukira masika, chotsukira masika chosalala kenako cholumikizira ma cell.

Patatha sabata imodzi kapena kuposerapo mutakhazikitsa, onetsetsani kuti mabotolo anu onse a terminal akadali olimba. Mabotolo otayirira angayambitse kulumikizana kosalimba, kulanda magetsi a EV yanu ndikupangitsa kutentha kwambiri.

Langizo 4: Chaja pafupipafupi komanso mozungulira pang'onopang'ono

Ndimabatire a lithiamu, mudzakhala ndi moyo wautali wa maselo ngati mutapewa kutuluka magazi kwambiri. Tikukulimbikitsani kuti mutsatire 70-80% DoD (Kuzama kwa Kutuluka kwa Magazi) pokhapokha ngati pachitika ngozi.

Maselo Otupa

Kutupa kumachitika kokha ngati selo latulutsidwa mopitirira muyeso kapena nthawi zina ladzazidwa mopitirira muyeso. Kutupa sikutanthauza kuti selo silingagwiritsidwenso ntchito ngakhale kuti chifukwa cha zimenezi likhoza kutaya mphamvu zina.
