Umthamo omkhulu, amandla amakhulu, usayizi omncane, isisindo esilula, ukukhiqizwa kwenqwaba okulula, kanye nokusetshenziswa kwezingxenye ezishibhile kuyinselele ekuklameni amabhethri e-EV.Ngamanye amazwi, kubilisa izindleko nokusebenza.Cabanga ngakho njengesenzo sokulinganisa, lapho i-kilowatt-hour (kWh) ezuziwe idinga ukuhlinzeka ngebanga eliphezulu, kodwa ngezindleko ezizwakalayo zokukhiqiza.Ngenxa yalokho, uzobona ngokuvamile izincazelo zephakethe lebhethri zibala izindleko zabo zokukhiqiza, kanye nezinombolo, ezisukela ku-$240 ukuya ku-$280/kWh. ngesikhathi sokukhiqiza, isibonelo.
O, futhi masingakhohlwa ukuphepha.Khumbula i-Fiasco ye-Samsung Galaxy Note 7 eminyakeni embalwa edlule, kanye nebhethri ye-EV elilingana nokusha kwezimoto kanye nokuncibilika okulinganayo kwe-Chernobyl.Esimeni senhlekelele ye-runaway chain reaction, izikhala nezilawuli ezishisayo phakathi kwamaseli ebhethri. ukupakisha ukuvimbela iseli elilodwa ukuthi lingashisi elinye, elinye, njll., engeza ebunkingeni bokuthuthukiswa kwebhethri ye-EV.Phakathi kwabo, ngisho noTesla unezinkinga.
Ngenkathi iphakethe lebhethri le-EV liqukethe izingxenye ezintathu ezibalulekile: amaseli ebhethri, isistimu yokuphatha ibhethri, nohlobo oluthile lwebhokisi noma isiqukathi esiwabambayo, okwamanje, sizobheka amabhethri nokuthi avele kanjani nge-Tesla, kodwa kuseyinkinga kwaToyota.
Ibhethri ye-cylindrical 18650 ibhethri ye-lithium-ion enobubanzi obuyi-18 mm, ubude obungu-65 mm nesisindo esingaba amagremu angu-47. Nge-voltage ebizwa ngokuthi i-3.7 volts, ibhethri ngalinye lingashaja kuze kufike ku-4.2 volts futhi likhiphe njengoba liphansi. njengama-volts angu-2.5, igcina kufika ku-3500 mAh iseli ngalinye.
Ngokufana nama-electrolytic capacitor, amabhethri emoto kagesi ka-Tesla ahlanganisa amashidi amade e-anode ne-cathode, ahlukaniswa ngezinto ezifaka i-charge-insulating, asongwe futhi ahlanganiswe ngokuqinile kumasilinda ukuze konge isikhala futhi agcine amandla amaningi ngangokunokwenzeka. Amashidi e-anode (ashajwe kahle) ngalinye linamathebhu okuxhuma amashaji afanayo phakathi kwamaseli, okuholela ebhethrini elinamandla—ahlanganisa nelilodwa, uma uthanda.
Njenge-capacitor, yandisa amandla ayo ngokunciphisa isikhala phakathi kwe-anode namashidi we-cathode, ishintsha i-dielectric (into evikelayo engenhla phakathi kwamashidi) ibe nemvume ephezulu, futhi ikhulise indawo ye-anode ne-cathode. Isinyathelo esilandelayo kubhethri (lamandla) i-Tesla EV yi-2170, enesilinda esikhudlwana kune-18650, esikala u-21mm x 70mm futhi sinesisindo esingamagremu angu-68. ama-volts nokukhishwa okuphansi njenge-2.5 volts, igcina kufika ku-4800 mAh iseli ngalinye.
Kukhona ukuhwebelana, nokho, okumayelana nokumelana nokushisa kuqhathaniswa nokudinga imbiza enkulu kancane.Endabeni ye-2170, ukwanda kosayizi wepuleti le-anode/cathode kubangela indlela yokushaja ende, okusho ukumelana okwengeziwe, ngakho-ke ngaphezulu. amandla aphuma ebhethrini njengokushisa futhi aphazamise imfuneko yokushaja ngokushesha.
Ukwakha ibhethri lesizukulwane esilandelayo esinamandla engeziwe (kodwa ngaphandle kokumelana okukhulayo), onjiniyela bakwa-Tesla baklame ibhethri elikhulu kakhulu elinomklamo obizwa ngokuthi “amatafula” ofinyeza indlela kagesi futhi ngaleyo ndlela anciphise inani lokushisa elikhiqizwa ukumelana . Okuningi kwalokhu kungabangelwa ukuthi ubani ongaba abacwaningi bebhethri abahamba phambili emhlabeni.
Ibhethri ye-4680 iklanywe ngendlela ye-helix enethayela ukuze yenziwe kalula, enosayizi wephakheji ongu-46mm ububanzi no-80mm ubude.Nokho, iseli ngalinye lilinganiselwe cishe ku-9000 mAh, okuyikhona okwenza amabhethri e-Tesla flat-panel abe ngcono kakhulu.Futhi, isivinini sayo sokushaja sisalungele ukufunwa ngokushesha.
Ngenkathi ukukhulisa usayizi weseli ngalinye kunokushwabana kungase kubonakale kungqubuzana nezidingo zokuklanywa kwebhethri, ukuthuthukiswa kwamandla nokulawula okushisayo kwe-4680 uma kuqhathaniswa no-18650 no-2170 kuholele kumaseli ambalwa kakhulu uma kuqhathaniswa nokusebenzisa ibhethri lango-18650 kanye no-2170. Amamodeli we-Tesla anikwe amandla ngaphambili anamandla engeziwe ngephakethe lebhethri ngalinye elinosayizi ofanayo.
Ngokombono wezinombolo, lokhu kusho ukuthi cishe amaseli angu-960 “4680” adingekayo ukuze agcwalise isikhala esifanayo namaseli angu-4,416 “2170”, kodwa ngezinzuzo ezengeziwe ezifana nezindleko zokukhiqiza eziphansi nge-kWh ngayinye nokusebenzisa 4680 Iphakethe lebhethri linyusa amandla kakhulu.
Njengoba kushiwo, i-4680 kulindeleke ukuthi inikeze ngokuphindwe ka-5 isitoreji samandla namandla aphindwe ka-6 uma kuqhathaniswa nebhethri engu-2170, okusho ukuthi ikhuphuka okulindelekile yokushayela isuka ku-82 kWh iye ku-95 kWh ku-Teslas Mileage entsha ikhuphuka ngo-16%.
Khumbula, lokhu kumane kuyizisekelo zamabhethri e-Tesla, kukhona okuningi ngemuva kobuchwepheshe.Kodwa lesi yisiqalo esihle sesihloko esizayo, njengoba sizofunda ukuphatha ukusetshenziswa kwamandla ephakethe lebhethri, kanye nokulawula izinkinga zokuphepha ezizungezile. ukukhiqiza ukushisa, ukuphelelwa amandla, kanye… Yebo… ubungozi bokusha kwebhethri le-EV.
Uma uthanda i-All-Things-Tesla, nali ithuba lakho lokuthenga inguqulo ye-Hot Wheels RC ye-Tesla Cybertruck.
