Chifukwa chiyani batire la tsamba la BYD tsopano ndi nkhani yodziwika bwino?
"Batri ya tsamba" ya BYD, yomwe yakhala ikukambidwa kwambiri mumakampani kwa nthawi yayitali, yawulula mawonekedwe ake enieni.
Mwina posachedwapa anthu ambiri akhala akumva mawu oti "batire la blade", koma mwina sakudziwa bwino, kotero lero tifotokoza mwatsatanetsatane za "batire la blade".
Ndani anayamba kupereka batire la tsamba
Wapampando wa BYD, Wang Chuanfu, adalengeza kuti "batri ya tsamba" ya BYD (mbadwo watsopano wa mabatire a lithiamu iron phosphate) iyamba kupanga zinthu zambiri ku fakitale ya Chongqing mu Marichi chaka chino, ndipo mu Juni idalembedwa mu Han EV The nthawi yoyamba kunyamula. Kenako BYD idawonekeranso m'magawo a magalimoto komanso azachuma m'mapulatifomu akuluakulu atolankhani.
Chifukwa Chake Batri ya Tsamba
Batire ya tsamba la BYD yatulutsidwa pa 29 Marichi, 2020. Dzina lake lonse ndi batire ya lithiamu iron phosphate ya mtundu wa blade, yomwe imadziwikanso kuti "batire ya super lithium iron phosphate". Batireyi imagwiritsa ntchito ukadaulo wa lithiamu iron phosphate, ndipo idzakhala ndi chitsanzo cha BYD "Han".
Ndipotu, "batire la tsamba" ndi mbadwo watsopano wa batire ya lithiamu iron phosphate yomwe yatulutsidwa posachedwapa ndi BYD, kwenikweni, BYD yakhala ikuyang'ana kwambiri pakukula kwa "super lithium iron phosphate" kudzera mu kafukufuku wazaka zambiri, mwina wopanga akuyembekeza kuti kudzera m'dzina lakuthwa komanso lophiphiritsa, apeze chidwi ndi chikoka chochulukirapo.
Chithunzi cha kapangidwe ka batri la tsamba
Poyerekeza ndi batire ya lithiamu iron phosphate ya BYD yakale, kiyi ya "batire ya tsamba" imapangidwa popanda gawoli, yolumikizidwa mwachindunji mu paketi ya batire (monga ukadaulo wa CTP), motero imakulitsa kwambiri magwiridwe antchito ophatikizana.
Koma kwenikweni, BYD si kampani yoyamba kupanga ma batire amphamvu padziko lonse lapansi. Monga kampani yaikulu kwambiri padziko lonse lapansi yopanga mabatire amphamvu, Ningde Times idagwiritsa ntchito ukadaulo wa CPT isanafike BYD. Mu Seputembala 2019, Ningde Times idawonetsa ukadaulo uwu mu Frankfurt Motor Show.
Tesla, Ningde Times, BYD ndi Hive Energy, ayamba kupanga ndipo alengeza kuti apanga zinthu zokhudzana ndi CTP mochuluka, ndipo mapaketi a batri amphamvu opanda ma module akukhala njira yodziwika bwino yaukadaulo.
Phukusi la batri la lithiamu lachikhalidwe
Chomwe chimatchedwa gawo, ndi gawo la magawo oyenera omwe amapanga gawo, chingamvekenso ngati lingaliro la kusonkhana kwa magawo. Mu gawo ili la batire, maselo angapo, mizere yoyendetsera, mayunitsi oyesera ndi zigawo zina zofunika zothandizira kapangidwe zimagwirizanitsidwa pamodzi kuti apange gawo, lomwe limatchedwanso gawo.
Batire ya Ningde Times CPT
CPT (selo kupita ku paketi) ndi kuphatikiza mwachindunji kwa maselo mu paketi ya batri. Chifukwa cha kuchotsedwa kwa ulalo wolumikizira gawo la batri, chiwerengero cha ziwalo za paketi ya batri chimachepetsedwa ndi 40%, kuchuluka kwa kugwiritsa ntchito kwa paketi ya batri ya CTP kumawonjezeka ndi 15%-20%, ndipo magwiridwe antchito opangira amawonjezeka ndi 50%, zomwe zimachepetsa kwambiri mtengo wopanga batri yamagetsi.
Nanga bwanji mtengo wa batri la tsamba
Ponena za mtengo, batire ya lithiamu iron phosphate yokha sigwiritsa ntchito zitsulo zosowa monga cobalt, mtengo wake ndi ubwino wake. Zikumveka kuti msika wa maselo a batire a lithiamu a ternary wa 2019 umapereka pafupifupi 900 RMB / kW-h, pomwe ma cell a batire a lithiamu iron phosphate aperekedwa pafupifupi 700 RMB / kW-h, mtsogolomu tidzalemba Han mwachitsanzo, kutalika kwake kumatha kufika 605km, batire ikuyembekezeka kukhala yoposa 80kW-h, kugwiritsa ntchito mabatire a lithiamu iron phosphate kungakhale kotsika mtengo wa 16,000 RMB (2355.3 USD). Tangoganizirani galimoto ina yatsopano yamagetsi yakunyumba yokhala ndi mtengo ndi kusiyana komweko monga BYD Han, batire yokha ili ndi ubwino wa 20,000 RMB (2944.16 USD), kotero ndizodziwikiratu kuti ndi iti yolimba kapena yofooka.
M'tsogolomu, BYD Han EV ili ndi mitundu iwiri: mtundu wa mota imodzi yokhala ndi mphamvu ya 163kW, torque yayikulu ya 330N-m ndi mtundu wa NEDC wa 605km; mtundu wa mota ziwiri wokhala ndi mphamvu ya 200kW, torque yayikulu ya 350N-m ndi mtundu wa NEDC wa 550km.
Pa Ogasiti 12, zanenedwa kuti batire ya BYD yaperekedwa ku Gigafactory Berlin ya Tesla, yomwe ikuyembekezeka kukhala ndi batire yamagalimoto a Tesla omwe achotsedwa pamzerewu kumapeto kwa Ogasiti mpaka kumayambiriro kwa Seputembala, pomwe fakitale yayikulu ya Tesla ku Shanghai ilibe mapulani ogwiritsira ntchito mabatire a BYD.
teslamag.de yatsimikiza kuti nkhaniyi ndi yoona. Galimoto ya mtundu wa Y yokhala ndi mabatire a BYD akuti yalandira chilolezo kuchokera ku EU, chomwe chidaperekedwa ndi Dutch RDW (Dutch Ministry of Transport) pa Julayi 1, 2022. Mu chikalatachi, galimoto yatsopano ya mtundu wa Y imatchedwa Mtundu wa 005, yokhala ndi mphamvu ya batri ya 55 kWh komanso mtunda wa makilomita 440.
Kodi ubwino wa mabatire a tsamba ndi wotani?
Zotetezeka:M'zaka zaposachedwapa, ngozi zachitetezo cha magalimoto zamagetsi zakhala zikuchitika kawirikawiri, ndipo zambiri mwa izo zimayambitsidwa ndi moto wa mabatire. "Batire la tsamba" linganenedwe kuti ndi chitetezo chabwino kwambiri pamsika. Malinga ndi zoyeserera za BYD pa mayeso olowera msomali wa batire, titha kuwona kuti "batire la tsamba" litalowa, kutentha kwa batire kumatha kusungidwa pakati pa 30-60 ℃, izi zili choncho chifukwa dera la batire la tsamba ndi lalitali, lalikulu pamwamba komanso kutentha kumachepa mwachangu. Ouyang Minggao, katswiri wa maphunziro a Chinese Academy of Sciences, adanenanso kuti kapangidwe ka batire la tsamba kumapangitsa kuti lipange kutentha kochepa ndikuchotsa kutentha mwachangu likamafupikitsidwa, ndipo adawunika momwe limagwirira ntchito mu "mayeso olowera msomali" ngati abwino kwambiri.
Kuchuluka kwa mphamvu:Poyerekeza ndi mabatire a lithiamu a ternary, mabatire a lithiamu iron phosphate ndi otetezeka ndipo amakhala ndi moyo wautali, koma kale mphamvu ya batri yakhala ikukanikizidwa mutu. Tsopano batire ya tsamba ya wh/kg kachulukidwe kuposa m'badwo wakale wa mabatire, ngakhale kuti mphamvu ya wh/l yawonjezeka ndi 9%, koma yawonjezeka ndi 50%. Ndiye kuti, mphamvu ya batire ya "tsamba" ikhoza kuwonjezeka ndi 50%.
Batire limakhala nthawi yayitali:Malinga ndi zoyeserera, nthawi yogwiritsira ntchito batire ya tsamba imapitirira nthawi 4500, mwachitsanzo kuwonongeka kwa batire kumakhala kochepera 20% pambuyo poyigwiritsa ntchito nthawi 4500, nthawi yogwiritsira ntchito batire ya lithiamu ya ternary imapitirira nthawi 3, ndipo nthawi yofanana ndi yomwe batire ya tsamba imatha kupitirira 1.2 miliyoni km.
Kodi mungagwire bwanji ntchito yabwino pamwamba pa chipolopolo chapakati, mbale yoziziritsira, chivundikiro chapamwamba ndi chapansi, thireyi, baffle ndi zina kuti mukwaniritse zofunikira zachitetezo cha insulation, insulation ya kutentha, yoletsa moto, yosapsa ndi kukwaniritsa zofunikira pakupanga zokha? Ndi vuto lalikulu komanso udindo wa fakitale yopaka utoto munthawi yatsopanoyi.
