Gxila kubhethri le-BMW i3

Kusukela ngo-2013 iBMW i3 itholakala ngamakhono amathathu: 60 Ah, 94 Ah kanye 120 Ah. Lokhu kunyuka komthamo manje kuvumela ibanga le-WLTP elingu-285 kuya ku-310 km ukuba lifunwe nebhethri elingu-42 kWh.

BMW i3 Ibhethri

Ibhethri ku-BMW i3 isebenzisa ubuchwepheshe be-lithium-ion, okwamanje obubhekwa njengobuchwepheshe obusebenza kahle kakhulu embonini yezimoto ngokulingana kwamandla kanye nobubanzi.

Amabhethri anamandla amakhulu adingekayo kuzo zonke izimoto zikagesi zakwa-BMW atholakala ezimbonini zamabhethri ezintathu zenkampani edolobheni. I-Dingolfing (Germany), Spartanburg (USA) kanye neShenyang (China). I-BMW Group iphinde yathola indawo yokukhiqiza amabhethri anamandla amakhulu e-Thailand embonini yayo i-Rayong, lapho isebenza khona ne-Dräxlmaier Group. Le nethiwekhi izohambisana nokukhiqizwa kwezingxenye zebhethri namabhethri anamandla kagesi ezimbonini ze-BMW Group e-Regensburg nase-Leipzig kusukela maphakathi no-2021.

Ukuze kuthuthukiswe ubuchwepheshe bebhethri, abakwaBMW bavula isikhungo sabo sokusebenza ngamabhethri ngo-2019. Ibhilidi elingu-8 m000 elitholakala eJalimane lihlala abacwaningi abangama-2 nochwepheshe abagxile kwi-physics, chemistry kanye ne-electromobility. Ngokungeziwe kumalabhorethri ocwaningo, umkhiqizi udale isitshalo sokulinga ukukhiqiza kabusha zonke izigaba zokukhiqizwa kwamaseli ebhethri. Lolu phiko luzoqedwa ngo-200. 

Ithathela olwazini lwesikhungo sekhono lamaseli ebhethri futhi ngokuhamba kwesikhathi kusukela embonini yokuhlola, i-BMW Group izohlinzeka ngobuchwepheshe bebhethri obusezingeni eliphezulu futhi ivumele abahlinzeki ukuba benze amaseli ebhethri ngokwezicaciso zabo.

Amabhethri enzelwe ukusebenza emazingeni okushisa asukela ku -25 kuya +60 degrees Celsius. Nokho, ukuze ushaje kabusha, izinga lokushisa kufanele libe phakathi kuka-0 no-60 degrees. 

Kodwa-ke, uma imoto ipake ngaphandle futhi izinga lokushisa liphansi, imoto idinga ukufudumeza amabhethri ngaphambi kokuba iqale ukuwashaja. Ngokufanayo, emazingeni okushisa aphezulu kakhulu, imoto inganciphisa amandla esistimu ye-voltage ukuze ivumele ukupholisa. Ezimweni ezimbi kakhulu, isibonelo, uma isistimu iqhubeka nokushisa naphezu kokuncipha kokukhishwa kwamandla, imoto ingase ime okwesikhashana.

Uma imoto ipakile futhi ingawasebenzisi amabhethri ayo, asaphelelwa amandla. Lokhu kulahlekelwa kulinganiselwa kokuthi 5% ngemuva kwezinsuku ezingama-30.

BMW i3 autonomy

I-BMW i3 inikeza izinhlobo ezintathu zamabhethri e-lithium-ion:

I-60 Ah inamandla angu-22 kWh, okungasetshenziswa u-18.9 kWh, futhi imemezela ukuzimela okungu-190 km kumjikelezo weNEDC noma u-130 kuya ku-160 km wokuzimela uma isetshenziswa ngempela. 

I-94 Ah ihambisana namandla angu-33 kWh (iwusizo 27.2 kWh), okungukuthi, uhla lwe-NEDC lwamakhilomitha angu-300 kanye nobubanzi bangempela buka-200 km. 

Amandla angu-120 Ah angu-42 kWh ebangeni le-WLTP ukusuka ku-285 kuya ku-310 km.

Izinto ezithinta ukuzimela

Ukuzimela kwangempela kuncike ezintweni ezimbalwa: izinga lebhethri, uhlobo lomzila (umgwaqo onguthelawayeka, idolobhakazi noma okuxubile), isimo somoya noma ukushisisa, isibikezelo sezulu, ukuphakama komgwaqo...

Izindlela zokushayela ezihlukene nazo zingathinta ububanzi. I-ECO PRO ne-ECO PRO + ikuvumela ukuthi uthole ukuzimela okungamakhilomitha angama-20 lilinye. 

Uhla lweBMW i3 lunganwetshwa ngalo "Range Extender" (Rex). Lena i-thermal autonomy expander enamandla angu-25 kW noma angu-34 amahhashi. Indima yayo ukushajwa kabusha ibhethri. Isebenza ngethangi elincane likaphethiloli elingu-9 litre.

I-Rex ivumela ukuzimela okungafika ku-300 km uma ifakwe ku-22 kWh iphasela, futhi ifinyelele ku-400 km ehambisana nephakheji engu-33 kWh. I-BMW i3 rex ibiza ngaphezulu, kodwa le nketho yanyamalala lapho kwethulwa imodeli engu-42 kWh!

Hlola ibhethri

I-BMW ivumela amabhethri ayo iminyaka engu-8 ukuya ku-100 km. 

Kodwa-ke, kuye ngokusetshenziswa kwemoto kagesi, ibhethri liyakhishwa futhi lingaholela ekwehleni kobubanzi. Kubalulekile ukuhlola ibhethri leBMW i3 esetshenzisiwe ukuze uthole isimo sayo sempilo.

I-La Belle Batterie ikunikeza isitifiketi sebhethri enokwethenjelwa futhi ezimele.

Noma ngabe ufuna ukuthenga noma ukuthengisa i-BMW i3 eke yasetshenziswa, lesi sitifiketi sizokuvumela ukuthi wehlise umoya futhi uqinisekise abathengi bakho ngokubanikeza ubufakazi bempilo yebhethri lakho.

Ukuze uthole isitifiketi sebhethri, okumele ukwenze nje uku-oda Ikhithi yethu Yebhethri ye-La Belle bese uxilonga ibhethri lakho usekhaya emizuzwini emi-5 nje. Ezinsukwini ezimbalwa uzothola isitifiketi esinolwazi olulandelayo:

 Isimo Sezempilo (SOH) : Leli iphesenti lokuguga kwebhethri. I-BMW i3 entsha ino-100% SOH.

 I-BMS (Uhlelo Lokuphatha Ibhethri) kanye nokuhlela kabusha : kuyindaba yokwazi ukuthi i-BMS isivele yahlelwa kabusha.

 Ukuzimela kwethiyori : lokhu ukuhlola ukuzimela I-BMW i3 kucatshangelwa ukuguga kwebhethri, izinga lokushisa langaphandle kanye nohlobo lohambo (umjikelezo wasemadolobheni, umgwaqo omkhulu kanye nokuxubile).

Isitifiketi sethu sihambisana namandla amathathu ebhethri: 60 Ah, 94 Ah kanye no-120 Ah!
