Izindaba - Ukulahlekelwa Ububanzi Bebhethri Le-Lithium Yasebusika? Amathiphu Ayisihluthulelo Ngohlelo Lokuphathwa Kwebhethri

Njengoba amazinga okushisa ehla, abanikazi bezimoto zikagesi (i-EV) bavame ukubhekana nenkinga ekhungathekisayo: ukwehla kwebanga lebhethri le-lithium. Isimo sezulu esibandayo sinciphisa ukusebenza kwebhethri, okuholela ekunqanyulweni kwamandla ngokuzumayo kanye nokunciphisa ibanga—ikakhulukazi ezindaweni ezisenyakatho. Ngenhlanhla, ngokulungiswa okufanele kanye nokwethenjelwaUhlelo Lokuphathwa Kwebhethri (i-BMS), lezi zinkinga zingancishiswa ngempumelelo. Ngezansi kunezeluleko eziqinisekisiwe zokuvikela amabhethri e-lithium nokugcina ukusebenza kahle kulobu busika.

Okokuqala, sebenzisa imisinga yokushaja ehamba kancane. Izinga lokushisa eliphansi linciphisa ukunyakaza kwama-ion ngaphakathi kwamabhethri e-lithium. Ukusebenzisa imisinga ephezulu (1C noma ngaphezulu) njengasehlobo kuphumela ekubeni amandla angamuncwanga aphenduke ukushisa, okuyingozi yokuvuvukala nokuwohloka kwebhethri. Ochwepheshe batusa ukushaja ku-0.3C-0.5C ebusika—lokhu kuvumela ama-ion ukuthi angene kancane kuma-electrode, okuqinisekisa ukushaja okuphelele nokunciphisa ukuguguleka. IkhwalithiUhlelo Lokuphathwa Kwebhethri (i-BMS)iqapha ukushaja kwamanje ngesikhathi sangempela ukuvimbela ukugcwala ngokweqile.

Okwesibili, qiniseka ukuthi amazinga okushisa okushaja angaphezu kuka-0℃. Ukushaja ngaphansi kwezinga le-zero kukhiqiza i-lithium dendrites, elimaza amaseli ebhethri futhi ibe yingozi yokuphepha. Izixazululo ezimbili ezisebenzayo: thatha uhambo olufushane lwemizuzu emi-5-10 ukuze ufudumale ibhethri ngaphambi kokushaja, noma ufake ifilimu yokushisa ehambisana ne-BMS.I-BMS isebenza ngokuzenzakalelayonoma ivala isifudumezi lapho izinga lokushisa lebhethri lifinyelela emingceleni esethiwe, isuse imikhuba eyingozi njengokushisa ilangabi elivulekile.

Okwesithathu, nciphisa ukujula kokukhishwa (DOD) kube ngu-80%. Ukukhipha amabhethri e-lithium ngokugcwele ebusika (100% DOD) kubangela umonakalo wangaphakathi ongenakuguqulwa, okuholela ezinkingeni "zamandla abonakalayo". Ukuyeka ukukhishwa lapho amandla angu-20% ehlala kugcina ibhethri lisebangeni elisebenza kakhulu, okuzinzisa ibanga. I-BMS ethembekile isiza ukulawula i-DOD kalula ngomsebenzi wayo wokuvikela ukukhishwa.

Amathiphu amabili okulungisa: gwema ukugcina isitoreji sesikhathi eside esisezingeni eliphansi lokushisa—paka ama-EV emagaraji ukuze uvimbele ukulahlekelwa unomphela komsebenzi webhethri. Kumabhethri angasebenzi, ukushaja okwengeziwe okungu-50%-60% umthamo masonto onke kubalulekile. I-BMS enokuqapha okude ivumela abasebenzisi ukulandelela i-voltage kanye nezinga lokushisa noma nini, iqinisekisa ukulungiswa ngesikhathi.

Uhlelo Lokuphathwa Kwebhethri (i-BMS) olusezingeni eliphezulu lubalulekile empilweni yebhethri lasebusika. Izici zalo ezithuthukisiwe, okuhlanganisa ukuqapha amapharamitha ngesikhathi sangempela kanye nokuvikelwa okuhlakaniphile, kuvikela amabhethri ekushajeni nasekukhipheni okungafanele. Ngokulandela lawa macebiso nokusebenzisa i-BMS ethembekile, abanikazi be-EV bangagcina amabhethri abo e-lithium esebenza kahle phakathi nobusika.
