Chiyambi：
Kuchaja kwa mphindi 5 ndi mtunda wa makilomita 400! Pa 17 Marichi, BYD idatulutsa njira yake ya "megawatt flash charging", yomwe ingathandize magalimoto amagetsi kutchaja mwachangu monga momwe zimakhalira ndi mafuta.
Komabe, kuti akwaniritse cholinga cha "mafuta ndi magetsi pa liwiro lomwelo", BYD ikuoneka kuti yafika pa malire a batire yake ya lithiamu iron phosphate. Ngakhale kuti mphamvu ya lithiamu iron phosphate ikufika pa malire ake, BYD ikukankhirabe kapangidwe ka zinthu ndi kukonza ukadaulo kwambiri.
Sewerani mopitirira muyeso! 10C lithiamu iron phosphate
Choyamba, malinga ndi zomwe zatulutsidwa pamsonkhano wa atolankhani wa BYD, ukadaulo wa BYD wochaja ma flash umagwiritsa ntchito chinthu chotchedwa "batri ya flash charging blade", chomwe chikadali mtundu wa batri ya lithiamu iron phosphate.
Izi sizimangowononga mphamvu ya mabatire a lithiamu okwera mtengo kwambiri monga mabatire a nickel ternary pamsika wochaja mwachangu, komanso zimathandiza BYD kukweza magwiridwe antchito a lithiamu iron phosphate kachiwiri, zomwe zimathandiza BYD kupitilizabe mtengo wake pamsika munjira yaukadaulo ya mabatire a lithiamu iron phosphate.
Malinga ndi deta yomwe BYD yatulutsa, BYD yafika pa mphamvu yayikulu yochaja ya megawati imodzi (1000 kW) pa mitundu ina monga Han L ndi Tang L, ndipo chaji ya flash ya mphindi 5 imatha kuwonjezera mtunda wa makilomita 400. Batire yake ya 'flash chaji' yafika pamlingo wochaja wa 10C.
Kodi lingaliro limeneli ndi lotani? Ponena za mfundo za sayansi, pakadali pano zikudziwika m'makampani kuti kuchuluka kwa mphamvu kwa mabatire a lithiamu iron phosphate kuli pafupi ndi malire a chiphunzitso. Nthawi zambiri, pofuna kutsimikizira kuchuluka kwa mphamvu, opanga amasiya mphamvu zawo zina zolipirira ndi kutulutsa. Kawirikawiri, kutulutsa kwa 3-5C kumaonedwa kuti ndi mlingo woyenera wotulutsira mabatire a lithiamu iron phosphate.
Komabe, nthawi ino BYD yawonjezera kuchuluka kwa lithiamu iron phosphate yomwe imatuluka kufika pa 10C, zomwe sizikutanthauza kuti mphamvu yamagetsi yawonjezeka kawiri kokha, komanso zikutanthauza kuti kukana kwamkati ndi vuto la kuyang'anira kutentha kwawonjezeka kawiri.
BYD ikunena kuti pogwiritsa ntchito tsamba, "batri yochaja flash" ya BYD imakonza kapangidwe ka ma electrode a batri ya tsamba, kuchepetsa kukana kwa ma lithiamu ion kusamuka ndi 50%, motero kukwaniritsa chiwongola dzanja choposa 10C koyamba.
Pa zinthu zabwino za electrode, BYD imagwiritsa ntchito zinthu za lithiamu iron phosphate za m'badwo wachinayi zokhala ndi chiyero chapamwamba, kuthamanga kwambiri, komanso kuchuluka kwamphamvu, komanso njira zophwanyira za nanoscale, zowonjezera zapadera za formula, ndi njira zophikira kutentha kwambiri. Kapangidwe kabwino kwambiri ka kristalo wamkati ndi njira yayifupi yofalitsira ma lithiamu ions kumawonjezera kuchuluka kwa ma lithiamu ions, potero kuchepetsa kukana kwa batri mkati ndikuwongolera magwiridwe antchito otulutsa.
Kuphatikiza apo, pankhani yosankha ma electrode ndi ma electrolyte oipa, ndikofunikiranso kusankha abwino kwambiri. Kugwiritsa ntchito graphite yopangira yokhala ndi malo apamwamba komanso kuwonjezera ma electrolyte a PEO (polyethylene oxide) apamwamba kwakhalanso zofunikira kuti zithandizire mabatire a 10C lithium iron phosphate.
Mwachidule, kuti tikwaniritse bwino ntchito yathu, BYD siwononga ndalama zambiri. Pa msonkhano wa atolankhani, mtengo wa BYD Han L EV yokhala ndi batire ya "flash charging" wafika pa 270000-350000 yuan, yomwe ndi yokwera pafupifupi 70000 yuan kuposa mtengo wa 2025 EV intelligent driving version (701KM Honor model).
Kodi nthawi yogwira ntchito komanso chitetezo cha mabatire ochaja ndi chiyani?
Zachidziwikire, kwa akatswiri aukadaulo wapamwamba, kukhala okwera mtengo si vuto. Aliyense akuda nkhawabe ndi mtundu ndi chitetezo cha chinthucho. Ponena za izi, Lian Yubo, Wachiwiri kwa Purezidenti wa BYD Group, adati mabatire ochaja a flash amatha kukhala ndi moyo wautali ngakhale atachajidwa pamitengo yapamwamba kwambiri, ndi kuwonjezeka kwa 35% kwa moyo wa batri.
Tinganene kuti yankho la BYD nthawi ino ndi lolungama komanso lodzaza ndi luso, osakana kuti mphamvu yowonjezera mphamvu imakhudza moyo wa batri.
Chifukwa kwenikweni, kuyitanitsa ndi kutulutsa mwachangu kudzakhala ndi zotsatira zosasinthika pa kapangidwe ka batri. Kuyitanitsa ndi kutulutsa mwachangu, kumakhudza kwambiri moyo wa batri. Ponena za kuyitanitsa kwambiri, kugwiritsa ntchito nthawi yayitali nthawi zambiri kumachepetsa moyo wa batri ndi 20% mpaka 30%. Chifukwa chake, opanga ambiri amalimbikitsa kuyitanitsa kwambiri ngati njira yolipirira mwadzidzidzi.
Opanga ena amapanga njira yowonjezerera mphamvu ya batri chifukwa cha kusintha kwa nthawi ya moyo wa batri. Kuchepa kwa nthawi ya moyo wa batri chifukwa cha kuwonjezera mphamvu ya moyo wa batri kumachepetsedwa ndi kuwonjezeka kwa nthawi ya moyo wa batri ndi wopanga, zomwe zimapangitsa kuti chinthu chonsecho chikhale ndi mphamvu yabwino yowonjezerera mphamvu ya batri mkati mwa nthawi yomwe chikuyembekezeka.
Kuphatikiza apo, kuti akwaniritse "kuchaja kwa flash", BYD yakhazikitsanso zosintha zingapo zamakina okhudzana ndi zofooka za mabatire a lithiamu iron phosphate ndi makina onse opangira magetsi.
Pofuna kulipira zofooka za kutentha kochepa m'mabatire a lithiamu iron phosphate, dongosolo la BYD la "flash charging" limayambitsa chipangizo chotenthetsera cha pulse kuti chizisunga mphamvu yachangu ya batri kudzera mu kutentha yokha m'malo ozizira. Nthawi yomweyo, kuti athe kuthana ndi kutentha kwa batri komwe kumachitika chifukwa cha kutchaja ndi kutulutsa mphamvu zambiri, chipinda cha batri chimalumikizidwa ndi njira yowongolera kutentha kwamadzimadzi yoziziritsira, yomwe imachotsa mwachindunji kutentha kwa batri kudzera mu refrigerant.
Ponena za chitetezo, lithiamu iron phosphate yatsimikiziranso kufunika kwake. Malinga ndi BYD, batire yake ya "flash charging" yapambana mosavuta mayeso ophwanyidwa a matani 1200 ndi mayeso ogundana a 70km/h. Kapangidwe ka mankhwala kokhazikika komanso mphamvu zoletsa moto za lithiamu iron phosphate zimaperekanso chitsimikizo chofunikira kwambiri cha chitetezo cha magalimoto amagetsi.
Kukumana ndi vuto la kuyitanitsa
Mwina anthu ambiri alibe lingaliro la mphamvu ya megawatt, koma ndikofunikira kumvetsetsa kuti megawatt imodzi ikhoza kukhala mphamvu ya fakitale yapakatikati, mphamvu yokhazikika ya chomera chaching'ono chamagetsi cha dzuwa, kapena kugwiritsa ntchito magetsi kwa anthu chikwi chimodzi.
Inde, mwamva bwino. Mphamvu yochajira ya galimoto ndi yofanana ndi ya fakitale kapena malo okhala. Malo ochajira magetsi ndi ofanana ndi mphamvu yogwiritsira ntchito magetsi ya theka la msewu. Kuchuluka kwa mphamvu yogwiritsira ntchito magetsi kumeneku kudzakhala vuto lalikulu pa gridi yamagetsi ya m'mizinda yomwe ilipo.
Sikuti palibe ndalama zomangira malo ochajira, koma kuti mumange malo ochajira kwambiri, ndikofunikira kukonzanso gridi yamagetsi yonse ya mzinda ndi msewu. Monga momwe zimakhalira popanga ma dumplings makamaka mbale ya viniga, pulojekitiyi imafuna khama lalikulu. Ndi mphamvu zake zomwe zilipo pano, BYD yangokonzekera kumanga malo ochajira flash opitilira 4000 mdziko lonse mtsogolo.
Malo ochajira ma flash a 4000 'megawatt' sikokwanira kwenikweni. "Mabatire ndi" magalimoto ochajira ma flash ndi gawo loyamba lofikira "mafuta ndi magetsi pa liwiro lomwelo".
Ndi kupita patsogolo kwa ukadaulo wa magalimoto amagetsi ndi mabatire, vuto lenileni layamba kusamukira ku ntchito yomanga malo opangira magetsi ndi maukonde amagetsi. BYD ndi CATL, komanso makampani ena a mabatire ndi magalimoto amagetsi ku China, angakumane ndi mwayi waukulu pamsika pankhaniyi.
