Iindaba - Uluhlu lweVoltage yoMlawuli: Isitshixo kwi-EV yeBattery Compatibility & BMS

Abanini be-EV abaninzi bayazibuza ukuba yintoni emisela i-voltage yokusebenza kwemoto yabo- ingaba yibhetri okanye yimoto? Okumangalisayo kukuba, impendulo ilele kumlawuli we-elektroniki. Eli candelo libalulekileyo liseka uluhlu olusebenzayo lombane oluchaza ukuhambelana kwebhetri kunye nokusebenza kwenkqubo iyonke.

Amandla ombane asemgangathweni we-EV abandakanya i-48V, i-60V, kunye ne-72V iinkqubo, nganye inoluhlu oluthile lokusebenza:

Iinkqubo ze-48V zihlala zisebenza phakathi kwe-42V-60V
Iinkqubo ze-60V zisebenza ngaphakathi kwe-50V-75V
Iinkqubo ze-72V zisebenza kunye noluhlu lwe-60V-89V

Abalawuli abakumgangatho ophakamileyo banokuphatha i-voltages engaphezulu kwe-110V, enikezela ukuguquguquka okukhulu.

Ukunyamezela kwamandla omlawuli kuchaphazela ngokuthe ngqo ukuhambelana kwebhetri ye-lithium ngeNkqubo yoLawulo lweBattery (BMS). Iibhetri zeLithium zisebenza ngaphakathi kweeplatifti ezithile zombane eziguquguqukayo ngexesha lokutshaja/lokukhupha. Xa amandla ombane ebhetri egqithisa kumlinganiselo ongaphezulu womlinganiselo womlawuli okanye iwela ngaphantsi komqobo osezantsi, isithuthi asiyi kuqalisa - nokuba ithini ibhetri ihlawulwe ngeyona ndlela.

Qwalasela le mizekelo yokwenyani:

Ibhetri ye-72V lithium nickel-manganese-cobalt (NMC) eneeseli ezingama-21 ifikelela kwi-89.25V xa ihlajiwe ngokupheleleyo, yehla ukuya kutsho malunga ne-87V emva kokuhla kwamandla ombane wesekethe. Ngokufanayo, ibhetri ye-lithium iron phosphate (LiFePO4) ye-72V kunye neeseli ze-24 ifezekisa i-87.6V ngentlawulo epheleleyo, iyancipha ukuya kwi-82V. Ngelixa zombini zihleli ngaphakathi kwemida ephezulu yesilawuli, iingxaki zivela xa iibhetri zisondela ekuphumeni.

Umba obalulekileyo wenzeka xa amandla ombane ebhetri ehla ngaphantsi komda ophantsi womlawuli ngaphambi kokuba ukhuseleko lwe-BMS lusebenze. Kule meko, iindlela zokukhusela zomlawuli zithintela ukukhupha, okwenza isithuthi singasebenzi nangona ibhetri isenawo amandla asebenzisekayo.

Olu dlelwane lubonisa ukuba kutheni ulungelelwaniso lwebhetri kufuneka luhambelane neenkcukacha zomlawuli. Inani leeseli zebhetri kuthotho lixhomekeke ngokuthe ngqo kuluhlu lwamandla ombane womlawuli, ngelixa ukalisho lwangoku lomlawuli lumisela i-BMS efanelekileyo yenkcazo yangoku. Oku kuxhomekeka kugxininisa ukuba kutheni ukuqonda iiparamitha zomlawuli kubalulekile kuyilo olufanelekileyo lwenkqubo ye-EV.

Ukusombulula ingxaki, xa ibhetri ibonisa amandla ombane aphumayo kodwa ingakwazi ukuqalisa isithuthi, iiparamitha zokusebenza zomlawuli kufuneka zibe yindawo yokuqala yophando. ISistim yoLawulo lweBhetri kunye nomlawuli kufuneka asebenze ngemvisiswano ukuqinisekisa ukusebenza okuthembekileyo. Njengoko itekhnoloji ye-EV iguquka, ukuqonda obu budlelwane busisiseko kunceda abanini kunye neechwephesha ukuba benze ngcono ukusebenza kwaye baphephe imiba ehambelanayo eqhelekileyo.
