Chifukwa chiyani BYD blade batri tsopano ndi mutu wovuta kwambiri
BYD's "blade batri", yomwe yakhala ikutsutsana kwambiri mumakampani kwa nthawi yayitali, idavumbulutsa 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 m'badwo 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 lakuthwa ndi ndi wophiphiritsa dzina, kupeza chidwi kwambiri ndi 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 kumawonjezeka ndi 15% -20%, ndipo kupanga bwino kumawonjezeka ndi 50%, zomwe zimachepetsa kwambiri mtengo wopangira 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 lifiyamu batire selo msika kupereka pafupifupi 900 RMB / kW-h, pamene kupereka lifiyamu chitsulo mankwala batire maselo pafupifupi 700 RMB / kW-h, m'tsogolo adzakhala kutchulidwa Han Mwachitsanzo, osiyanasiyana ake angafikire 605km, batire paketi akunenera kukhala oposa 80k phosphate batter akhoza kugwiritsa ntchito batter phosphate osachepera 80k 16,000 RMB(2355.3 USD) yotsika 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 ya tsamba la BYD yaperekedwa ku Gigafactory Berlin ya Tesla, yomwe ikuyembekezeka kukhala ndi batire ya Tesla magalimoto kuchokera pamzere kumapeto kwa Ogasiti mpaka kumayambiriro kwa Seputembala koyambirira, pomwe gigafactory ya Tesla ya Shanghai ilibe malingaliro ogwiritsira ntchito mabatire a BYD.
teslamag.de yatsimikizira kuti nkhaniyi ndi yowona. Model Y yokhala ndi mabatire a BYD akuti idalandira chivomerezo cha mtundu kuchokera ku EU, yomwe idaperekedwa ndi Dutch RDW (Dutch Ministry of Transport) pa Julayi 1, 2022. M'chikalatacho, Model Y yatsopano imatchedwa Type 005, yokhala ndi batri ya 55 kWh ndi kutalika kwa 440 km.
Ubwino wa mabatire atsamba ndi chiyani
Otetezeka:M'zaka zaposachedwa, ngozi zachitetezo chagalimoto yamagetsi zakhala zikuchitika pafupipafupi, ndipo zambiri zimayambitsidwa ndi moto wa batri. "Battery ya blade" ikhoza kunenedwa kuti ndiyo chitetezo chabwino kwambiri pamsika. Malinga ndi kafukufuku wofalitsidwa wa 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 padziko lapansi komanso kutentha kwachangu. 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 zatsopano, tsamba la batire kulipiritsa mkombero moyo kuposa nthawi 4500, ie kuwonongeka batire ndi zosakwana 20% pambuyo 4500 nthawi adzapereke, moyo kuposa 3 nthawi ternary lithiamu batire, ndi ofanana mtunda moyo wa batire tsamba akhoza upambana 1.2 miliyoni Km.
Kodi kuchita ntchito yabwino padziko pachimake chipolopolo, kuzirala mbale, chapamwamba ndi m'munsi chivundikirocho, thireyi, baffle ndi zigawo zina kuti akwaniritse zofunika chitetezo cha kutchinjiriza, kutchinjiriza kutentha, lawi retardant, fireproof ndi kukwaniritsa zofunika zodziwikiratu kupanga? Ndilo vuto lalikulu ndi udindo wa fakitale yokutira mu nthawi yatsopano.
