Imfihlakalo ye-EV Voltage Ixazululiwe: Indlela Izilawuli Zikuyalela Ngayo Ukuhambelana Kwebhethri

Abanikazi abaningi be-EV bayazibuza ukuthi yini enquma amandla ogesi wemoto yabo - ingabe ibhethri noma imoto? Ngokumangalisayo, impendulo ilele kusilawuli se-elekthronikhi. Le ngxenye ebalulekile isungula ububanzi bokusebenza kwamandla kagesi obukhomba ukuhambisana kwebhethri nokusebenza kohlelo lonke.

Ama-voltage ajwayelekile e-EV afaka amasistimu angu-48V, 60V, kanye nama-72V, ngalinye linamabanga athile okusebenza:
  • Amasistimu angu-48V ngokuvamile asebenza phakathi kuka-42V-60V
  • Amasistimu angu-60V asebenza phakathi kuka-50V-75V
  • Amasistimu we-72V asebenza nobubanzi be-60V-89V
    Izilawuli ezisezingeni eliphezulu zingakwazi ngisho nokusingatha ama-voltage angaphezu kuka-110V, zinikeza ukuguquguquka okukhulu.
Ukubekezelela i-voltage yesilawuli kuthinta ngokuqondile ukusebenzisana kwebhethri le-lithium ngoHlelo Lokuphathwa Kwebhethri (BMS)). Amabhethri e-lithium asebenza ngaphakathi kwamapulatifomu kagesi athile aguquguqukayo phakathi nemijikelezo yokushaja/yokukhipha. Uma amandla kagesi ebhethri edlula umkhawulo ongaphezulu wesilawuli noma iwela ngaphansi komkhawulo ophansi, imoto ngeke iqale - kungakhathaliseki ukuthi ibhethri ishaje kangakanani.
Ukuvalwa kwebhethri ye-EV

Cabangela lezi zibonelo zomhlaba wangempela:
Ibhethri le-lithium nickel-manganese-cobalt (NMC) elingu-72V elinamaseli angu-21 lifinyelela ku-89.25V uma lishajwe ngokugcwele, lehlela cishe ku-87V ngemva kokwehla kwamandla wesekethe. Ngokufanayo, ibhethri le-lithium iron phosphate (LiFePO4) elingu-72V elinamaseli angu-24 lifinyelela ku-87.6V ngokushajwa okuphelele, lehla liye cishe ku-82V. Nakuba zombili zihlala ngaphakathi kwemikhawulo ephezulu yesilawuli, izinkinga ziyavela lapho amabhethri esondela ekuphumeni.
Inkinga ebalulekile yenzeka lapho amandla kagesi ebhethri ehla ngaphansi komkhawulo omncane wesilawuli ngaphambi kokuthi ukuvikela kwe-BMS kusebenze. Kulesi simo, izindlela zokuvikela zesilawuli zivimbela ukuphuma, okwenza imoto ingasebenzi nakuba ibhethri lisenawo amandla asebenzisekayo.
Lobu budlelwano bubonisa ukuthi kungani ukulungiselelwa kwebhethri kufanele kuhambisane nezicaciso zesilawuli. Inombolo yamaseli ebhethri ochungechungeni incike ngokuqondile ebangeni le-voltage yesilawuli, kuyilapho isilinganiso samanje sesilawuli sinquma izicaciso ezifanele zamanje ze-BMS. Lokhu kuncike komunye nomunye kugqamisa ukuthi kungani ukuqonda amapharamitha esilawuli kubalulekile ekwakhiweni okufanele kwesistimu ye-EV.

Ukuze kuxazululwe inkinga, lapho ibhethri libonisa amandla kagesi aphumayo kodwa lingakwazi ukuqalisa imoto, imingcele yokusebenza yesilawuli kufanele ibe indawo yokuqala yophenyo. Uhlelo Lokuphatha Ibhethri kanye nesilawuli kufanele sisebenze ngokuzwana ukuze kuqinisekiswe ukusebenza okuthembekile. Njengoba ubuchwepheshe be-EV buthuthuka, ukuqaphela lobu budlelwano obuyisisekelo kusiza abanikazi nochwepheshe bathuthukise ukusebenza futhi bagweme izinkinga ezivamile zokusebenzisana.
