Kungani i-Tesla Model 3 ikhethe ibhethri le-21700?

I-Tesla ibe yisihloko sezindaba ekhaya nakwamanye amazwe muva nje, futhi kunezindaba ezimbi kakhulu mayelana nokubambezeleka nokuvalwa kwe-Model 3. Kodwa-ke, ngokudalulwa kolwazi olwengeziwe kanye nokuvezwa kwemingcele ye-Model3P80D, ushintsho olukhulu kakhulu ukusetshenziswa kwebhethri elisha le-21700 esikhundleni sebhethri yasekuqaleni.

Yini ibhethri le-18650

5 amabhethri ngo-18650 uma kuqhathaniswa ne-18650

Ukuze wenze ibhethri elingu-21700 libe lula ukuliqonda futhi kuthakazelise ukuxoxa nabangani bakho, ake sibuyekeze kafushane ibhethri lika-Tesla elingu-18650 lamanje. Phela isimiso siyefana.

Njengebhethri eyicylindrical, i-18650 inokubukeka okuhlukile kumabhethri ajwayelekile e-AA. Lokhu kuyenza isebenze kabanzi emikhiqizweni eyahlukene ye-elekthronikhi. Futhi uma kuqhathaniswa nebhethri lendabuko le-AA5, ivolumu inkulu futhi umthamo ungagcinwa kangcono.

Kufanele ngibale igama layo, ibhethri ye-cylindrical, banomthetho wokuqamba amagama olula, i-18650, isibonelo, ukubonisa okubili kokuqala, mangaki amamilimitha ububanzi lebhethri, inombolo imele ukuphakama nokuma kwebhethri (inombolo 0 ( Cylindrical), noma amabhethri angu-18650 anobubanzi obungu-18 mm nobude bamabhethri angama-cylindrical angu-65 mm. Izinga laqalwa nguSony, kodwa alizange libe lidumile ekuqaleni, ngoba umumo ungashintshwa ngokuvumelana nezidingo. .

Ngokuthuthukiswa kwamathoshi acwebezelayo, amakhompiyutha e-notebook, njll., i-18650 yangenisa isikhathi sayo somkhiqizo ophezulu. Ngaphezu kwabakhiqizi bangaphandle abanjengoPanasonic noSony, ama-workshops amancane ahlukahlukene asekhaya nawo aqala ukukhiqiza amabhethri anjalo. Kodwa-ke, uma kuqhathaniswa nesilinganiso somthamo wabakhiqizi bangaphandle ngaphezu kwe-3000ma, umthamo wemikhiqizo yasekhaya awuphakeme, futhi amabhethri amaningi afuywayo anokulawulwa kwekhwalithi embi, okulimaza ngokuqondile idumela lamabhethri angu-18650.

Kungani usebenzise ibhethri le-18650

Ibhethri le-IPhoneX lingelinye lalawa mabhethri astakiwe

I-Tesla ikhethe i-18650 ngenxa yobuchwepheshe bayo obuvuthiwe, ukuminyana kwamandla okuhle kakhulu, nokulawulwa kwekhwalithi okuzinzile. Ngaphezu kwalokho, njengomkhiqizi wezimoto osafufusa, uTesla wayengenabo ubuchwepheshe bokukhiqiza ibhethri ngaphambili, ngakho-ke kubiza kakhulu ukuthenga ngokuqondile imikhiqizo evuthiwe evela kubakhiqizi abahle kakhulu kunokucwaninga noma ukuthola imboni yokukhiqiza amabhethri ahlanganisiwe.

700Wh 18650 ibhethri iphakethe

Nokho, uma kuqhathaniswa namabhethri apakishiwe, i-18650 incane futhi inamandla omuntu siqu aphansi! Lokhu kusho ukuthi kudingeka amabhethri awodwa amaningi ukuze kwakheke iphakethe lebhethri elifanelekile ukuze kwandiswe ibanga lokuhamba kwemoto. Lokhu kudala inselele yobuchwepheshe: uphathwa kanjani izinkulungwane zamabhethri?

Ngenxa yalesi sizathu, u-Tesla udale isethi yesistimu yokulawula ibhethri ye-BMS yezinga eliphezulu ukuphatha izinkulungwane zamabhethri angu-18650 (ngenxa yobunzima besistimu yokuphatha, lesi sihloko ngeke siphinde, futhi ngizokuchazela kamuva). Ngaphansi kwesistimu yokuphatha enembile, inokulawula okuhle kakhulu kwekhwalithi yebhethri engu-18650 kanye nokungaguquguquki okuphezulu komuntu ngamunye, okwenza futhi isistimu yonke igcine ukulawuleka okuphezulu nokuzinza.

Kodwa ngenxa yokuthi uhlelo lokuphatha ibhethri ye-BMS lunzima kakhulu, luholela kwenye inkinga ebulalayo: indlela yokuxazulula inkinga yokushisa ukushisa kwesistimu yebhethri?!

Uma uqaqa ibhethri ye-smartphone yamanje, uzothola ukuthi igobolondo lebhethri alinzima kakhulu, kodwa livikelwe ipuleti elincane kakhulu le-aluminium. Inzuzo yalokhu ukuthi ingenziwa ibe mncane kakhulu, ngakho-ke akudingeki ukhathazeke kakhulu ngokuchithwa kokushisa. Kodwa okubi ukuthi kulula ukuphuka, ngisho nokugoba ngesandla, nokubhema.

18650 umkhono wensimbi ovikelayo

Kodwa ibhethri le-18650 lihlukile. Ngezizathu zokuphepha, ingaphezulu lebhethri limbozwe ngensimbi noma nge-aluminium alloy ukuvimbela ibhethri ukuthi lingaqhumi. Kodwa yilesi sakhiwo esiqinile esiletha izinselele ezinkulu ekunqanyulweni kokushisa, ikakhulukazi lapho amabhethri angu-8000 ehlanganiswa.

Uhlelo lwe-Tesla BMS

U-Tesla usebenzisa i-exhaust yenjini izikhathi eziningi ukupholisa amabhethri ngoketshezi ukuze aqinisekise ukuthi umehluko wezinga lokushisa phakathi kwebhethri ngalinye aweqi amadigri angu-5. Kodwa le ndlela yokupholisa iphakamisa enye inkinga: isisindo nezindleko!

Ngoba uma ukuminyana kwamandla ebhethri le-18650 kuqhathaniswa namandla ebhethri enqwabelene, inzuzo ye-18650 isobala. Kodwa uma ungeza isisindo sohlelo lokuphatha ibhethri le-BMS kuphakethe lebhethri le-18650, ukuminyana kwamandla amabhethri astakiwe kuzodlula i-18650! Lokhu kufakazela ukuthi luyinkimbinkimbi kangakanani uhlelo lwe-BMS. Ngakho-ke ukuxazulula izinkinga zesisindo nezindleko, isixazululo esilula ukufaka esikhundleni sebhethri le-18650 eliphelelwe yisikhathi.

Yiziphi izinzuzo zebhethri le-21700

Njengoba imikhiqizo yebhethri ye-cylindrical isivele ivuthiwe kakhulu, kungenzeka ukwandisa ububanzi buka-3mm nokuphakama kuka-50mm ngesisekelo se-original 18650, ukwandisa ngokuqondile ivolumu futhi ulethe i-Mah enkulu. Ngaphezu kwalokho, ngenxa yobukhulu bayo obukhulu, ibhethri ye-21700 inendlebe yezigaba eziningi, okwandisa kancane isivinini sokushaja kwebhethri. Ngaphezu kwalokho, ubukhulu bebhethri bukhulu, inani lamabhethri emotweni lizoncishiswa ngokuqhathaniswa, ngaleyo ndlela kuncishiswe inkimbinkimbi yesistimu ye-BMS, ngaleyo ndlela kuncishiswe isisindo nezindleko.

Ibhayisikili lentaba likagesi elinamabhethri angu-21,700

Kepha iTesla akuyona inkampani yokuqala ukusebenzisa amabhethri angama-21,700. Kusukela ngo-2015, iPanasonic yahola ekusebenziseni amabhethri emabhayisikili ayo kagesi. Kamuva, uTesla wabona ukuthi ukusetshenziswa kwaleli bhethri kuphumelela kakhulu, ngakho wahlongoza ukuthenga ukuthuthukiswa okufana nePanasonic. Ngokubambisana okubili kwesikhathi eside, kungokwemvelo ukuthi i-Model 3 isebenzise i-21700.

imodeli ingasebenzisa 21700

Ngokusho kukaMusk, angicabangi ukuthi izosetshenziswa esikhathini esizayo esiseduze, kodwa nakanjani izosetshenziswa enguqulweni elandelayo. Phela, leli bhethri lidlale indima enhle kakhulu ezindlekweni zokukhiqiza kanye nenani!

Ukwengeza, inkinga enkulu ebhekene nezimoto zikagesi ukuthi ubuchwepheshe bebhethri buzofinyelela nini ukugxuma kwekhwalithi. Kodwa uma ubhekisisa, kuphakamisa imibuzo emibili enzima kakhulu: yimuphi ongakhetha phakathi kwempilo ende yebhethri nokushaja okusheshayo. UMusk ubukeka ekhethe ukushaja ngokushesha ngoba ukubeke kwacaca ukuthi akafuni ukubona isamba semodeli neModelX sidlula ku-100 kWh.

I-chassis yemodeli ye-Tesla

Kukhona enye inkinga okufanele ixazululwe, futhi lokho ukwakhiwa kwe-chassis. Ubukhulu bebhethri ye-lithium ye-18650 buhlukile kubukhulu bebhethri ye-21700, okuholela ngokuqondile ekushintsheni ekuklanyeni kwe-chassis lapho iphakethe lebhethri lifakwe khona. Ngamanye amazwi, uTesla kuzodingeka ahlele kabusha i-chassis yamamodeli akhona ukuze afake amabhethri angama-21,700.

Idatha yakamuva ye-Model3P80D

I-Model3P80D okwamanje iyimodeli eyaziwa kakhulu ye-Model3 eyaziwayo, efakwe izinjini zikagesi ngaphambili nangemuva, eqaphela uhlelo lokushayela ngamasondo amane nge-fly-by-wire. Ukusheshisa okungu-0-100km/h ngemizuzwana engu-3.6, izimo zomgwaqo ezibanzi zibanga amakhilomitha angu-498! Umthamo wamaphakethe ebhethri angu-21,700 ngu-80.5 KWH, okuwumsuka wegama le-P80D.

I-BAIC New Energy van ifakwe i-21,700 yuan ye-lithium

Eqinisweni, ibhethri le-21700 akuwona ubuchwepheshe obuthuthukisiwe. Uma uvula i-Taobao, ungathola ibhethri elingu-21700. Ifanele futhi kumadivayisi aphathwayo njengamathoshi kanye nogwayi we-elekthronikhi njengebhethri ye-18650. Ngaphezu kwalokho, amaloli amabili asekhaya e-BAIC kanye ne-King Long asebenzise amaphakethe ebhethri angu-21,700 ekuqaleni kwehlobo eledlule. Kusukela kulo mbono, akubona ubuchwepheshe obumnyama, futhi abakhiqizi basekhaya nabo bayayikhiqiza, kodwa imfanelo ye-Model3 yetimu iyiphushela phambili. Engikukhathalela kakhulu ukuthi iModel 3 izolethwa nini eShayina!
