Iindaba - Ukulahleka koLuhlu lweeBhetri zeLithium zaseBusika? Iingcebiso eziphambili ngeNkqubo yoLawulo lweeBhetri

Njengoko amaqondo obushushu ehla, abanini bezithuthi zombane (i-EV) badla ngokujongana nomba okhathazayo: ukwehla komgama weebhetri ze-lithium. Imozulu ebandayo inciphisa ukusebenza kwebhetri, nto leyo ekhokelela ekucinyweni kombane ngequbuliso kunye nomgama omfutshane wokuhamba—ingakumbi kwimimandla esemantla. Ngethamsanqa, ngokugcinwa kakuhle kunye nokugcinwa okuthembekileyo.Inkqubo yoLawulo lweeBhetri (i-BMS)Ezi ngxaki zingancitshiswa ngempumelelo. Apha ngezantsi kukho iingcebiso eziqinisekisiweyo zokukhusela iibhetri ze-lithium kunye nokugcina ukusebenza kakuhle kobu busika.

Okokuqala, sebenzisa imisinga yokutshaja ecothayo. Amaqondo obushushu aphantsi acothisa intshukumo ye-ion ngaphakathi kweebhetri ze-lithium. Ukusebenzisa imisinga ephezulu (1C okanye ngaphezulu) njengasehlotyeni kubangela ukuba amandla angafunxwanga aguquke abe bubushushu, nto leyo ebeka emngciphekweni ukudumba kunye nokuwohloka kwebhetri. Iingcali zicebisa ukutshaja kwi-0.3C-0.5C ebusika—oku kuvumela ii-ion ukuba zingene kancinci kwii-electrodes, ukuqinisekisa ukutshaja ngokupheleleyo kunye nokunciphisa ukuguguleka. UmgangathoInkqubo yoLawulo lweeBhetri (i-BMS)ijonga ukutshaja komsinga ngexesha langempela ukuthintela ukugqithiswa kakhulu.

Okwesibini, qinisekisa ukuba amaqondo obushushu okutshaja angaphezulu kwe-0℃. Ukutshaja kwiimeko ezingaphantsi kwe-zero kuvelisa i-lithium dendrites, eyonakalisa iiseli zebhetri kwaye ibe yingozi kukhuseleko. Izisombululo ezibini ezisebenzayo: thatha uhambo olufutshane lwemizuzu emi-5-10 ukufudumeza ibhetri ngaphambi kokutshaja, okanye ufake ifilimu yokufudumeza edibene ne-BMS.I-BMS isebenza ngokuzenzekelayookanye ivala isifudumezi xa ubushushu bebhetri bufikelela kwimida ebekiweyo, isusa iindlela eziyingozi ezifana nokufudumeza ilangabi elivulekileyo.

Okwesithathu, nciphisa ubunzulu bokukhupha (DOD) ukuya kwi-80%. Ukukhupha ngokupheleleyo iibhetri ze-lithium ebusika (100% DOD) kubangela umonakalo wangaphakathi ongenakuguqulwa, okukhokelela kwiingxaki "zamandla abonakalayo". Ukuyeka ukukhupha xa amandla angama-20% ehlala ebhetri kugcina ibhetri ikwindawo yokusebenza okuphezulu, nto leyo egcina imileage izinzile. I-BMS ethembekileyo inceda ukulawula i-DOD ngokulula ngomsebenzi wayo wokukhusela ukukhupha.

Iingcebiso ezimbini ezongezelelweyo zokulungisa: phepha ukugcina ixesha elide kwindawo eshushu kakhulu—beka ii-EV kwigaraji ukuthintela ukulahleka okusisigxina komsebenzi webhetri. Kwiibhetri ezingasebenziyo, ukutshaja okongezelelweyo ukuya kumthamo we-50%-60% ngeveki kubalulekile. I-BMS enokubeka esweni kude ivumela abasebenzisi ukuba balandelele i-voltage kunye nobushushu nangaliphi na ixesha, ukuqinisekisa ukugcinwa ngexesha elifanelekileyo.

Inkqubo yoLawulo lweBhetri (i-BMS) ekumgangatho ophezulu ibalulekile kwimpilo yebhetri yasebusika. Iimpawu zayo eziphambili, kubandakanya ukujonga iiparameter ngexesha langempela kunye nokhuseleko olukrelekrele, zikhusela iibhetri ekutshajweni nasekukhutshweni kwebhetri ngendlela engafanelekanga. Ngokulandela la macebiso kunye nokusebenzisa i-BMS ethembekileyo, abanini be-EV banokugcina iibhetri zabo ze-lithium zisebenza kakuhle ebusika bonke.
