Kungani ibhethri le-BYD blade manje seliyisihloko esishisayo
I-"blade battery" ye-BYD, osekunenkulumo-mpikiswano eshubile embonini isikhathi eside, igcine iveze ukubukeka kwayo kwangempela.
Mhlawumbe muva nje abantu abaningi bebelokhu bezwa igama elithi "blade battery", kodwa mhlawumbe abajwayelene nalo, ngakho-ke namuhla sizochaza "ibhethri ye-blade" ngemininingwane.
Ubani owahlongoza kuqala ibhethri le-blade
USihlalo we-BYD u-Wang Chuanfu umemezele ukuthi i-BYD "blade battery" (isizukulwane esisha samabhethri e-lithium iron phosphate) sizoqala ukukhiqizwa ngobuningi embonini yaseChongqing ngo-March kulo nyaka, futhi ngo-June esohlwini lwe-Han EV Isikhathi sokuqala sokuthwala. Khona-ke i-BYD yaphinda futhi yaba sematheni ezingxenyeni zezimoto ngisho nezezimali zezinkundla ezinkulu zezindaba.
Kungani ibhethri ye-Blade
Ibhethri le-blade likhishwa yi-BYD ngoMashi 29, 2020. Igama layo eliphelele ibhethri yohlobo lwe-lithium iron phosphate, eyaziwa nangokuthi "ibhethri ye-lithium iron phosphate". Ibhethri isebenzisa ubuchwepheshe be-lithium iron phosphate, izoqala ifakwe imodeli ye-BYD "Han".
Eqinisweni, "ibhethri ye-blade" iyisizukulwane esisha sebhethri ye-lithium iron phosphate esanda kukhishwa yi-BYD, empeleni, i-BYD igxile ekuthuthukiseni "i-super lithium iron phosphate" eminyakeni eminingi yocwaningo , mhlawumbe umenzi uthemba ukuthi ngegama elibukhali nelingokomfanekiso, ukuze uthole ukunakwa nokuba nomthelela.
Umdwebo wesakhiwo sebhethri ye-blade
Uma kuqhathaniswa nebhethri ye-lithium iron phosphate yangaphambilini ye-BYD, ukhiye "webhethri ye-blade" wenziwa ngaphandle kwe-module, ehlanganiswe ngokuqondile nephakethe lebhethri (okungukuthi ubuchwepheshe be-CTP), ngaleyo ndlela kuthuthukisa kakhulu ukusebenza kahle kokuhlanganisa.
Kodwa empeleni, i-BYD akuyena umkhiqizi wokuqala ukusebenzisa ubuchwepheshe be-CPT. Njengomkhiqizi omkhulu webhethri wamandla afakiwe emhlabeni, i-Ningde Times yasebenzisa ubuchwepheshe be-CPT ngaphambi kwe-BYD. ngoSepthemba 2019, iNingde Times ikhombise lobu buchwepheshe embukisweni wezimoto iFrankfurt Motor Show.
I-Tesla, i-Ningde Times, i-BYD ne-Hive Energy, seziqalile ukuthuthukisa futhi zamemezela ukuthi zizokhiqiza ngobuningi imikhiqizo ehlobene ne-CTP, futhi amaphakethe ebhethri anamandla angaphansi kwemojuli aba umzila wobuchwepheshe ojwayelekile.
Iphakethe lebhethri le-lithium lendabuko
The okuthiwa module, iyingxenye izingxenye ezifanele bakha module, kungabuye kuqondwe njengoba umqondo izingxenye ukuhlangana. Kulo mkhakha wephakethe lebhethri, inani lamaseli, imigqa ye-conductive, amayunithi amasampula kanye nezinye izingxenye ezidingekayo zokusekela zesakhiwo kuhlanganiswe ndawonye ukwenza imojuli, ebizwa nangokuthi imojuli.
Iphakethe lebhethri le-Ningde Times CPT
I-CPT (iseli elizopakishwa) iwukuhlanganiswa okuqondile kwamaseli kuphakethe lebhethri. Ngenxa yokuqedwa kwesixhumanisi somhlangano wemojula yebhethri, inani lezingxenye zephakethe lebhethri lincishiswa ngo-40%, izinga lokusebenzisa ivolumu yephakethe lebhethri le-CTP likhuphuka ngo-15% -20%, kanye nokusebenza kahle kokukhiqiza kukhuphuka ngo-50%, okunciphisa kakhulu izindleko zokukhiqiza ibhethri lamandla.
Kuthiwani ngezindleko zebhethri le-blade
Ekhuluma ngezindleko, ibhethri ye-lithium iron phosphate ngokwayo ayisebenzisi izinsimbi ezingavamile njenge-cobalt, izindleko ziyinzuzo yayo. Kuyaqondakala ukuthi imakethe ye-2019 ternary lithium battery cell inikela cishe ku-900 RMB / kW-h, kuyilapho ukunikezwa kwamaseli ebhethri ye-lithium iron phosphate cishe ku-700 RMB / kW-h, esikhathini esizayo kuzofakwa ohlwini lwe-Han njengesibonelo, ibanga lingafinyelela ku-605km, iphakethe lebhethri libikezelwa ukuthi lingaphezu kuka-80kW-h, ukusetshenziswa kwamabhethri e-lithium iron phosphate kungaba okungenani u-16,000 RMB(2355.3 USD) ishibhile. Cabanga ngenye imoto yasekhaya enenani elifanayo nobubanzi obufana ne-BYD Han, iphekhi yebhethri iyodwa inenzuzo yenani elingu-20,000 RMB(2944.16 USD), ngakho kuyacaca ukuthi iliphi elinamandla noma elibuthakathaka.
Ngokuzayo, i-BYD Han EV inezinguqulo ezimbili: inguqulo ye-motor eyodwa enamandla angu-163kW, i-torque engu-330N-m ephakeme kanye nebanga le-NEDC elingu-605km; i-dual-motor enamandla angu-200kW, i-torque engu-350N-m ephezulu kanye nebanga elingu-550km le-NEDC.
Ngo-Agasti 12, kubikwa ukuthi, ibhethri le-BYD le-blade lilethwe ku-Tesla's Gigafactory Berlin, okulindeleke ukuthi ifakwe ibhethri lezimoto ze-Tesla ngaphandle komugqa ekupheleni kuka-Agasti kuya ekuqaleni kuka-September ekuqaleni, kanti i-gigafactory ye-Tesla yase-Shanghai ayinazo izinhlelo zokusebenzisa amabhethri e-BYD.
I-teslamag.de iqinisekise ubuqiniso bezindaba. I-Model Y enamabhethri e-BYD kubikwa ukuthi ithole ukugunyazwa kohlobo oluvela e-EU, okunikezwe i-Dutch RDW (Umnyango Wezokuthutha Wase-Dutch) ngoJulayi 1, 2022. Kudokhumenti, i-Model Y entsha ibizwa ngokuthi Uhlobo 005, amandla ebhethri angu-55 kWh kanye nobubanzi obungama-440 km.
Yiziphi izinzuzo zamabhethri e-blade
Kuphephe kakhudlwana:Eminyakeni yamuva nje, izingozi zokuphepha kwezimoto zikagesi bezivamile, futhi iningi lazo libangelwa ukusha kwamabhethri. "Ibhethri ye-blade" kungathiwa iwukuphepha okungcono kakhulu emakethe. Ngokusho kokuhlolwa okushicilelwe kwe-BYD ekuhlolweni kokungena kwebhethri, singabona ukuthi "ibhethri ye-blade" ngemuva kokungena, izinga lokushisa lebhethri lingagcinwa futhi phakathi kuka-30-60 ℃, lokhu kungenxa yokuthi isifunda sebhethri ye-blade yinde, indawo enkulu kanye nokushisa okusheshayo. ukuhlakazeka. U-Ouyang Minggao, isazi sezemfundo sase-Chinese Academy of Sciences, uveze ukuthi ukuklanywa kwebhethri ye-blade kuyenza ikhiqize ukushisa okuncane futhi ikhiphe ukushisa ngokushesha lapho ijikeleza, futhi ihlole ukusebenza kwayo "ekuhlolweni kokungena kwezinzipho" njengokuhle kakhulu.
Ukuminyana kwamandla aphezulu:Uma kuqhathaniswa namabhethri e-lithium e-ternary, amabhethri e-lithium iron phosphate aphephe kakhudlwana futhi anempilo yomjikelezo omude, kodwa ngaphambilini kumthamo webhethri webhethri bekucindezelwe ikhanda. Manje ukuminyana kwebhethri ye-blade wh/kg kunesizukulwane samabhethri sangaphambilini, nakuba inyuka ngo-9% ku-wh/l amandla okuminyana, kodwa ukwanda okungafika ku-50%. Okusho ukuthi, umthamo webhethri "we-blade" ungakhuphuka ngo-50%.
Impilo yebhethri ende:Ngokusho kocwaningo, impilo yomjikelezo wokushaja ibhethri ye-blade idlula izikhathi ezingama-4500, okungukuthi ukubola kwebhethri kungaphansi kuka-20% ngemuva kokushaja izikhathi ezingama-4500, impilo ingaphezu kwezikhathi ezi-3 zebhethri le-lithium ye-ternary, kanye nempilo yemayela elilinganayo lebhethri le-blade lingakwazi. ngaphezu kwe-1.2 million km.
Ungawenza kanjani umsebenzi omuhle ebusweni begobolondo eliwumgogodla, ipuleti lokupholisa, ikhava engaphezulu nephansi, ithreyi, i-baffle nezinye izingxenye ukuze kuzuzwe izidingo zokuphepha zokugquma, ukufakwa kwe-heat insulation, i-flame retardant, ingashi futhi ihlangabezane nezidingo zokukhiqiza okuzenzakalelayo. ? Kuyinselelo enkulu kanye nesibopho sefekthri yokumboza esikhathini esisha.
