Olu hlobo lwesixhobo lunokugqiba umahluko phakathi komthamo wangempela kunye nomthamo oqhelekileyo webhetri ngokukhutshwa rhoqo kwangoku.
2. Intlawulo yebhetri kunye nenkqubo yokuvavanya ukukhutshwa
Intlawulo yebhetri kunye nenkqubo yokuvavanya ukukhutshwa sisixhobo esinamandla sokuvavanya esinokulinganisa iimeko zokutshaja kunye nokukhupha ngexesha lokusetyenziswa kwangempela. Le nkqubo yokuvavanya isoloko isetyenziselwa ukubona ukusebenza kakuhle, ubomi bomjikelezo, ukuhlawuliswa kunye nokukhupha ukusebenza kwebhetri. Ivavanya ukusebenza kwebhetri phantsi kweemeko zokusebenza ezahlukeneyo ngokulawula ngokuchanekileyo iiparitha ezifana nentlawulo kunye nokukhupha okwangoku, i-voltage yentlawulo, i-voltage yokukhupha kunye nexesha.
3. Umvavanyi webhetri wangaphakathi
Ukuxhatshazwa kwangaphakathi kwebhetri yenye yezinto ezibalulekileyo ezichaphazela ukusebenza kweebhetri ze-lithium. Ukuchasana okugqithisileyo kwangaphakathi kunokubangela ukufudumala kwebhetri, ukunciphisa umthamo kunye neengxaki zokhuseleko. Iumvavanyi webhetri yangaphakathiibala ukuchasana kwangaphakathi kwebhetri ngokulinganisa utshintsho lwe-voltage yebhetri phantsi kweentlawulo ezahlukeneyo kunye neemeko zokukhupha. Oku kubaluleke kakhulu ekuvavanyeni impilo yebhetri kunye nokuqikelela ubomi bebhetri.
4. Isifanisi sebhetri
I-simulator yebhetri sisixhobo sokuvavanya esinokufanisa utshintsho kwi-voltage kunye neempawu zangoku zeebhetri ze-lithium. Ihlala isetyenziswa ekuphuhliseni nasekuvavanyeni iinkqubo zolawulo lwebhetri (BMS). Ilinganisa ukuziphatha okuguquguqukayo kwebhetri ekusetyenzisweni okwenyani ngokudibanisa umthwalo we-elektroniki kunye nonikezelo lwamandla, inceda abasebenzi be-R&D ukuba bavavanye impendulo yenkqubo yolawulo lwebhetri kwintlawulo eyahlukeneyo kunye neemeko zokukhupha.
