Izici Ezingu-6 Zokuvikela Ezingukhiye Ongazibheka Lapho Uthenga Amabhethri Anamandla Aphezulu Ngo-2023

1.Ukuvikela inkokhiso eyeqile

Ukuvikela ukushajwa ngokweqile kubhekisela kulokhu: amabhethri e-lithium ngesikhathi sokushaja, lapho amandla ogesi enyuka aye ngale kwebanga elifanele, azoletha ukungaqiniseki nobungozi.Umsebenzi wokuvikela ukushajwa okweqile kwebhodi lokuvikela ukuqapha amandla kagesi ephakethe lebhethri ngesikhathi sangempela, nokunqamula ukunikezwa kwamandla lapho ukushaja kufinyelela phezulu kwebanga lamandla kagesi aphephile, kuvimbe amandla kagesi ukuthi aqhubeke nokukhuphuka, ngaleyo ndlela kudlala i-voltage. indima yokuvikela.
Umsebenzi wokuvikela ukushaja okungaphezulu: Uma ushaja, ibhodi lokuvikela lizoqapha amandla kagesi eyunithi yezinhlamvu ngayinye yephakethe lebhethri ngesikhathi sangempela, inqobo nje uma eyodwa yamandla kagesi eyunithi yezinhlamvu ifinyelela inani lokuvikela ukushajwa ngokweqile (i-voltage yokushajwa ngokweqile kwe-ternary ingu-4.25V±0.05 V, kanye ne-voltage ye-overcharge ezenzakalelayo ye-LiFePO4.75V ± 0.05V), ibhodi lizonqamula ukunikezwa kwamandla, futhi lonke iqembu lamabhethri e-lithium lizoyeka ukushaja.

2.Ukuvikela ukukhishwa ngokweqile

Ukuvikelwa kokukhishwa ngokweqile kubhekisela ku: amabhethri e-lithium ohlelweni lokukhishwa, ngokuhla kwamandla kagesi, uma wonke ugesi ukhishwa ekuphelelweni amandla, izinto zamakhemikhali ngaphakathi kwebhethri ye-lithium zizolahlekelwa umsebenzi, okuholela ekushajeni emandleni noma ekunciphiseni kwamandla.Umsebenzi wokuvikela ukukhishwa ngokweqile kwebhodi lokuvikela ukuqapha amandla kagesi ephakethe lebhethri ngesikhathi sangempela, futhi unqamule ukunikezwa kwamandla lapho ushajwa ufike endaweni ephansi kakhulu.ye-voltage yebhethri, evimbela i-voltage ukuthi ingaqhubeki nokuwa, ukuze idlale indima yokuvikela.

Umsebenzi wokuvikela ukukhishwa ngokweqile: Lapho ikhipha, ibhodi lokuvikela lizoqapha amandla kagesi eyunithi yezinhlamvu ngayinye yephakethe lebhethri ngesikhathi sangempela, inqobo nje uma eyodwa yamandla kagesi eyunithi yezinhlamvu ifinyelela inani lokuvikela ukukhishwa ngokweqile (i-voltage ezenzakalelayo yokukhipha I-ternary ingu-2.7V±0.1V, futhi i-voltage ezenzakalelayo yokukhipha ngaphezulu kwe-LiFePO4 ingu-2.2V±0.1V), ibhodi lizonqamula ukunikezwa kwamandla, futhi lonke iqembu lamabhethri e-lithium lizoyeka ukushajwa.

3.Ukuvikela okweqile

Ukuvikelwa kwe-Overcurrent kubhekisela ku: amabhethri e-lithium ekunikezeni amandla ekulayisheni, okwamanje izoshintsha nge-voltage kanye nezinguquko zamandla, lapho okwamanje iphezulu kakhulu, kulula ukushisa ibhodi lokuvikela, ibhethri noma imishini.Umsebenzi wokuvikela owedlulele webhodi lokuvikela ukuqapha ukusebenza kwamanje kwephakethe lebhethri ngesikhathi sangempela phakathi nenqubo yokushaja nokukhipha, futhi lapho i-current idlula uhla lokuphepha, izonqamula ukudlula kwamanje, ivimbele i-current fro.m ukulimaza amabhethri noma izinto zokusebenza, ukuze udlale indima yokuvikela.

Umsebenzi wokuvikela we-Overcurrent: lapho ushaja futhi ukhipha, ibhodi lokuvikela lizoqapha iphakethe lebhethri lamanje ngesikhathi sangempela, inqobo nje uma lifinyelela inani lokuvikela elibekiwe, ibhodi lokuvikela lizonqamula ukunikezwa kwamandla, kanye neqembu lonke lamabhethri e-lithium. izoyeka ukushaja nokukhipha.

Ukuvikelwa kwe-4.high / low lokushisa

Ukuvikelwa kokulawula izinga lokushisa: I-probe yokulawula izinga lokushisa yebhodi lokuvikela ihadiwe ishiselwe ebhodini lomama langaphakathi lebhodi lokuvikela futhi alikwazi ukukhishwa.I-probe yokulawula izinga lokushisa ingaqapha ukuguqulwa kwezinga lokushisa kwephakethe lebhethri noma indawo yokusebenza ngesikhathi sangempela, lapho izinga lokushisa eliqashiwe lidlula inani elibekiwe (okuzenzakalelayo kokuvikelwa kokulawula izinga lokushisa kwehadiwe: ukushaja -20 ~ 55 ℃, ukukhipha -40 ~ 75 ℃, engashintshwa ngokuvumelana nezidingo zekhasimende, futhi ikhasimende alikwazi ukusetha ngokwalo), iphakethe lebhethri lizonqanyulwa ekushajweni nasekukhishweni, futhi iphakethe lebhethri lingaqhubeka nokushajwa futhi likhishwe uma izinga lokushisa liphakeme. ibuyiselwe ebangeni eliphusile ukuze idlale indima ekuvikelweni.

5.Ukuvikelwa kokulingana
Ukulinganisa kwe-Passive kusho: uma kunokungahambisani kwe-voltage phakathi kwezintambo zamabhethri, ibhodi lokuvikela lizolungisa i-voltage yentambo ngayinye ukuze ihambisane ngesikhathi sokushaja p.i-rocess.

Umsebenzi wokulinganisa: Lapho ibhodi lokuvikela lithola umehluko wevoltheji phakathi kochungechunge lwebhethri ye-lithium nezintambo, lapho ishaja, izintambo zikagesi eziphezulu zifinyelela inani lokulinganisa (i-ternary: 4.13V, LiFe3.525V), ikhiphe (idla) ngesixhasi sokulinganisa nge wamanje ongaba ngu-30-35mA, kanti ezinye izintambo zamandla kagesi aphansi ziyaqhubeka nokushaja.Qhubeka kuze kugcwale.

6.ukuvikelwa kwesekethe emfushane (ukutholwa kwephutha + ukuvikelwa kokuxhumeka okuphambene nokuhlehla)
I-short circuit isho: i-short circuit yakhiwa lapho amatheminali ebhethri axhumene ne-directly ngaphandle komthwalo.Ukujikeleza okufushane kuzoholela ekulimaleni kwebhethri, imishini nokunye.

Umsebenzi wokuvikela isiyingi esifushane: ibhethri ye-lithium ngokungaqondile ebangelwa isiyingi esifushane (njengokuxhuma umugqa ongalungile, thatha umugqa ongalungile, amanzi nezinye izizathu), ibhodi lokuvikela lizoba esikhathini esifushane kakhulu (imizuzwana engu-0.00025) , inqamule indlela yomsinga, ukuze idlale indima yokuvikela.
