Chifukwa chiyani BYD blade batire tsopano ndi mutu wovuta kwambiri
BYD's "blade batri", yomwe yakhala ikutsutsana kwambiri mumakampani kwa nthawi yayitali, yatulutsa mawonekedwe ake enieni.
Mwina posachedwapa anthu ambiri akhala akumva mawu akuti "blade batri", koma mwina sadziwa bwino, kotero lero tifotokoza mwatsatanetsatane "batire lakuda".
Amene poyamba anafunsira batire tsamba
BYD Wapampando Wang Chuanfu analengeza kuti BYD "tsamba batire" (m'badwo watsopano wa mabatire lifiyamu chitsulo mankwala) adzayamba kupanga misa mu Chongqing fakitale mu March chaka chino, ndi June kutchulidwa Han EV Nthawi yoyamba kunyamula. Kenako BYD idagundanso mitu yamagalimoto komanso magawo azachuma pamapulatifomu akulu atolankhani.
Chifukwa chiyani Blade Battery
Batire ya blade imatulutsidwa ndi BYD pa Marichi 29, 2020. Dzina lake lonse ndi blade mtundu wa lithiamu iron phosphate battery, yomwe imadziwikanso kuti "super lithium iron phosphate battery". Batire imagwiritsa ntchito ukadaulo wa lithiamu iron phosphate, idzakhala yoyamba ndi mtundu wa BYD "Han".
Ndipotu, "tsamba batire" ndi mbadwo watsopano wa lifiyamu chitsulo mankwala batire posachedwapa anamasulidwa ndi BYD, Ndipotu, BYD wakhala lolunjika pa chitukuko cha "wapamwamba lifiyamu chitsulo mankwala" mwa zaka zambiri za kafukufuku , mwina Mlengi akuyembekeza kuti kudzera m'dzina lakuthwa komanso lophiphiritsa, kuti mukhale ndi chidwi komanso chikoka.
Chithunzi cha mawonekedwe a batri la blade
Poyerekeza ndi BYD yapita lifiyamu chitsulo mankwala batire, chinsinsi cha "tsamba batire" wapangidwa popanda gawo, mwachindunji Integrated mu batire paketi (ie CTP luso), potero kwambiri kuwongolera dzuwa kusakanikirana.
Koma kwenikweni, BYD si Mlengi woyamba kugwiritsa ntchito CPT luso. Monga kampani yayikulu kwambiri padziko lonse lapansi yopanga batire yamagetsi, Ningde Times idagwiritsa ntchito ukadaulo wa CPT BYD isanachitike. mu September 2019, Ningde Times anasonyeza luso limeneli mu Frankfurt Njinga Show.
Tesla, Ningde Times, BYD ndi Hive Energy, ayamba kupanga ndikulengeza kuti adzapanga zinthu zambiri zokhudzana ndi CTP, ndipo mapaketi a batri opanda mphamvu a module akukhala njira yamakono yamakono.
Traditional ternary lithiamu batire paketi
Zomwe zimatchedwa gawo, ndi gawo la magawo ofunikira omwe amapanga gawo, amathanso kumveka ngati lingaliro la magawo a msonkhano. Pankhani iyi ya batire paketi, ma cell angapo, mizere yoyendetsa, magawo a zitsanzo ndi zida zina zofunika zothandizira zimaphatikizidwa pamodzi kuti apange module, yomwe imatchedwanso module.
Ningde Times CPT batire paketi
CPT (cell to pack) ndikuphatikizana mwachindunji kwa ma cell mu paketi ya batri. Chifukwa cha kuchotsedwa kwa ulalo wa msonkhano wa batri, kuchuluka kwa magawo a batire kumachepetsedwa ndi 40%, kuchuluka kwa magwiritsidwe a CTP batire kumachulukitsidwa ndi 15% -20%, ndikuchita bwino kwachulukidwe ndi 50%, zomwe zimachepetsa kwambiri mtengo wopanga batire yamagetsi.
Nanga bwanji mtengo wa batire la blade
Ponena za mtengo, batire ya lithiamu iron phosphate palokha sigwiritsa ntchito zitsulo zosowa monga cobalt, mtengo wake ndi mwayi wake. Zikumveka kuti 2019 ternary lithiamu batire cell msika kupereka pafupifupi 900 RMB / kW-h, pamene kupereka lithiamu chitsulo mankwala batire maselo pafupifupi 700 RMB / kW-h, m'tsogolo adzakhala kutchulidwa Han Mwachitsanzo, ake osiyanasiyana akhoza kufika 605km, batire paketi ananeneratu kukhala oposa 80kW-h, ntchito lithiamu chitsulo mankwala mabatire kungakhale osachepera 16,000 RMB (2355.3 USD) mtengo. Tangoganizani galimoto ina yapanyumba yamagetsi yomwe ili ndi mtengo wofanana ndi BYD Han, batire yokhayo ili ndi mtengo wamtengo wapatali wa 20,000 RMB(2944.16 USD), kotero zikuwonekeratu kuti ndi yamphamvu kapena yocheperako.
M'tsogolomu, BYD Han EV ili ndi mitundu iwiri: imodzi-motor version yokhala ndi mphamvu ya 163kW, 330N-m peak torque ndi 605km NEDC range; mitundu iwiri ya injini yokhala ndi mphamvu ya 200kW, torque ya 350N-m yokwanira ndi 550km NEDC osiyanasiyana.
Pa Ogasiti 12, akuti, batire la BYD laperekedwa ku Gigafactory Berlin ya Tesla, yomwe ikuyembekezeka kukhala ndi batire ya Tesla magalimoto kumapeto kwa Ogasiti mpaka kumayambiriro kwa Seputembala koyambirira, pomwe gigafactory ya Tesla ya Shanghai. alibe mapulani ogwiritsira ntchito mabatire a BYD.
teslamag.de yatsimikizira kuti nkhaniyi ndi yowona. Mabatire a Model Y okhala ndi BYD akuti adalandira chivomerezo cha mtundu kuchokera ku EU, chomwe chidaperekedwa ndi Dutch RDW (Dutch Ministry of Transport) pa Julayi 1, 2022. M'chikalatacho, Model Y yatsopano imatchedwa Type 005, ndi batire mphamvu 55 kWh ndi osiyanasiyana 440 Km.
Ubwino wa mabatire atsamba ndi chiyani
Otetezeka:M'zaka zaposachedwa, ngozi zachitetezo cha magalimoto amagetsi zakhala zikuchitika pafupipafupi, ndipo zambiri zimayambitsidwa ndi moto wa batri. "Battery ya blade" ikhoza kunenedwa kuti ndiyo chitetezo chabwino kwambiri pamsika. Malinga ndi zoyeserera zofalitsidwa za BYD pa mayeso olowera msomali wa batri, titha kuwona kuti "batire yamtundu" itatha kulowa, kutentha kwa batri kumatha kusungidwa pakati pa 30-60 ℃, izi ndichifukwa choti dera la batire la tsamba ndi lalitali, lalikulu pamtunda komanso kutentha kwachangu. kuwonongeka. Ouyang Minggao, katswiri wa maphunziro a Chinese Academy of Sciences, adanena kuti mapangidwe a batire la blade amachititsa kuti azitentha pang'ono ndikuchotsa kutentha mofulumira pamene akuyenda pang'onopang'ono, ndikuwunika momwe amachitira "mayeso olowera msomali" ngati abwino kwambiri.
Kuchuluka kwa mphamvu:Poyerekeza ndi mabatire ternary lithiamu, lithiamu chitsulo mankwala mabatire ndi otetezeka ndipo ndi moyo wautali mkombero, koma kale mu batire mphamvu kachulukidwe wakhala mbamuikha mutu. Tsopano kachulukidwe ka batire la wh / kg kuposa m'badwo wakale wa mabatire, ngakhale 9% ikuwonjezeka mu wh / l mphamvu yamagetsi, koma kuwonjezeka kwa 50%. Ndiko kuti, mphamvu ya batri ya "blade batri" ikhoza kuwonjezeka ndi 50%.
Moyo wautali wa batri:Malinga ndi zoyeserera, batire yamtundu wa batire yozungulira moyo imaposa nthawi za 4500, ie, kuwonongeka kwa batire ndi zosakwana 20% pambuyo pa kuthamangitsa nthawi 4500, moyo umaposa 3 nthawi za ternary lithiamu batire, ndi moyo wofananira wa batire la batire. kuposa 1.2 miliyoni Km.
Momwe mungapangire ntchito yabwino pamwamba pa chipolopolo chapachiyambi, mbale yozizira, chivundikiro chapamwamba ndi chotsika, thireyi, baffle ndi zigawo zina kuti mukwaniritse zofunikira za chitetezo cha kutchinjiriza, kutchinjiriza kutentha, retardant lawi, moto ndi kukwaniritsa zofunikira za kupanga makina. ? Ndilo vuto lalikulu ndi udindo wa fakitale yokutira mu nthawi yatsopano.
