Izindaba - Ibanga Le-Voltage Yokulawula: Isihluthulelo Sokuhambisana Kwebhethri le-EV kanye ne-BMS

Abanikazi abaningi bezimoto ze-EV bayazibuza ukuthi yini enquma i-voltage yokusebenza kwezimoto zabo - ingabe ibhethri noma injini? Ngokumangalisayo, impendulo iku-electronic controller. Lesi sici esibalulekile sisungula ububanzi bokusebenza kwe-voltage obunquma ukuhambisana kwebhethri kanye nokusebenza kohlelo lonke.

Ama-voltage ajwayelekile e-EV afaka phakathi izinhlelo ezingu-48V, 60V, kanye no-72V, ngayinye inezinhlobo ezithile zokusebenza:

Izinhlelo ze-48V ngokuvamile zisebenza phakathi kuka-42V no-60V
Izinhlelo ze-60V zisebenza ngaphakathi kwe-50V-75V
Izinhlelo ze-72V zisebenza ngama-range angu-60V-89V

Izilawuli eziphezulu zingaphatha ngisho nama-voltage angaphezu kuka-110V, okunikeza ukuguquguquka okukhulu.

Ukubekezelelana kwamandla kagesi omlawuli kuthinta ngqo ukuhambisana kwebhethri le-lithium ngeSistimu Yokuphatha Ibhethri (i-BMS). Amabhethri e-lithium asebenza ngaphakathi kwamapulatifomu athile kagesi ashintshashintshayo ngesikhathi sokujikeleza kokushaja/ukukhipha. Lapho amandla kagesi ebhethri edlula umkhawulo ophezulu womlawuli noma ewela ngaphansi komkhawulo wayo ophansi, imoto ngeke iqale - kungakhathaliseki ukuthi ibhethri linjani ngempela.

Cabanga ngalezi zibonelo zangempela:

Ibhethri le-72V lithium nickel-manganese-cobalt (NMC) elinamaseli angu-21 lifinyelela ku-89.25V uma selishajwe ngokugcwele, lehle laya cishe ku-87V ngemva kokwehla kwe-voltage yesekethe. Ngokufanayo, ibhethri le-72V lithium iron phosphate (LiFePO4) elinamaseli angu-24 lifinyelela ku-87.6V uma selishajwe ngokugcwele, lehle laya cishe ku-82V. Nakuba womabili ehlala ngaphakathi kwemingcele evamile yokulawula, kuvela izinkinga lapho amabhethri esondela ekukhishweni.

Inkinga ebalulekile yenzeka lapho i-voltage yebhethri yehla ngaphansi komkhawulo omncane wesilawuli ngaphambi kokuba isivikelo se-BMS sisebenze. Kulesi simo, izindlela zokuvikela zesilawuli zivimbela ukukhishwa, okwenza imoto ingasebenzi yize ibhethri lisaqukethe amandla angasetshenziswa.

Lobu budlelwano bubonisa ukuthi kungani ukucushwa kwebhethri kufanele kuhambisane nokucaciswa kwesilawuli. Inani lamaseli ebhethri ochungechungeni lincike ngqo ebangeni lamandla kagesi lesilawuli, kuyilapho isilinganiso samanje sesilawuli sinquma ukucaciswa kwamanje kwe-BMS okufanele. Lokhu kuncika kugcizelela ukuthi kungani ukuqonda amapharamitha esilawuli kubalulekile ekwakhiweni kwesistimu ye-EV efanele.

Ukuze kuxazululwe izinkinga, lapho ibhethri libonisa i-voltage yokuphuma kodwa lingakwazi ukuqala imoto, amapharamitha okusebenza esilawuli kufanele abe yindawo yokuqala yokuphenya. Uhlelo Lokuphathwa Kwebhethri kanye nesilawuli kumele kusebenze ngokuvumelana ukuqinisekisa ukusebenza okuthembekile. Njengoba ubuchwepheshe be-EV buthuthuka, ukuqaphela lobu budlelwano obuyisisekelo kusiza abanikazi kanye nochwepheshe ukuthuthukisa ukusebenza futhi bagweme izinkinga ezivamile zokuhambisana.
