Sei bhatiri rebanga reBYD rava nyaya inonyanya kutaurwa?
"Bhatiri remuti weBlade" raBYD, iro rave richikurukuriranwa zvakanyanya muindasitiri kwenguva yakareba, razopedzisira raburitsa pachena chitarisiko charo chechokwadi.
Pamwe munguva pfupi yapfuura vanhu vazhinji vanga vachinzwa izwi rekuti "blade battery", asi pamwe havanyatsorizivi, saka nhasi tichatsanangura "blade battery" zvakadzama.
Ndiani akatanga kupa bhatiri rebanga
Sachigaro weBYD, Wang Chuanfu, akazivisa kuti "bhatiri remuti" reBYD (chizvarwa chitsva chemabhatiri e lithium iron phosphate) richatanga kugadzirwa mufekitori yeChongqing munaKurume gore rino, uye muna Chikumi rakanyorwa muHan EV The kekutanga kutakura. Zvadaro BYD yakasvika zvakare mumisoro yemotokari uye kunyange muzvikamu zvemari zvemapuratifomu makuru enhau.
Nei Bhatiri reNereza
Bhatiri reblade rakaburitswa neBYD musi wa29 Kurume, 2020. Zita rayo rakazara nderekuti bhatiri re lithium iron phosphate remhando yeblade, rinozivikanwawo se "super lithium iron phosphate battery". Bhatiri iri rinoshandisa tekinoroji ye lithium iron phosphate, uye richatanga rakagadzirwa ne BYD "Han" model.
Kutaura zvazviri, "bhatiri rebanga" chizvarwa chitsva chebhatiri re lithium iron phosphate rakaburitswa neBYD, kutaura zvazviri, BYD yakatarisana nekuvandudzwa kwe "super lithium iron phosphate" kuburikidza nemakore mazhinji ekutsvaga, pamwe mugadziri anotarisira kuti kuburikidza nezita rakajeka uye rekufananidzira, kuwana kutariswa kwakawanda uye simba.
Dhayagiramu yechimiro chebhatiri reblade
Kana tichienzanisa nebhatiri rekare re lithium iron phosphate reBYD, kiyi ye "blade battery" inogadzirwa isina module, yakabatanidzwa zvakananga mubhatiri (kureva tekinoroji yeCTP), nokudaro ichivandudza zvakanyanya kushanda kwekubatanidza.
Asi kutaura chokwadi, BYD haisiriyo kambani yekutanga kushandisa tekinoroji yeCPT. Semugadziri mukuru wemabhatiri emagetsi akaiswa pasi rose, Ningde Times yakashandisa tekinoroji yeCPT pamberi peBYD. munaGunyana 2019, Ningde Times yakaratidza tekinoroji iyi muFrankfurt Motor Show.
Tesla, Ningde Times, BYD uye Hive Energy, vatanga kugadzira uye vazivisa kuti vachagadzira zvigadzirwa zvine chekuita neCTP zvakawanda, uye mapaketi emabhatiri emagetsi asina module ari kuva nzira huru yetekinoroji.
Paketi yebhatiri yeTerinari yeLithium yechinyakare
Iyo inonzi module, chikamu chezvikamu zvakakosha zvinoumba module, inogonawo kunzwisiswa sepfungwa yekuungana kwezvikamu. Mundima iyi yebhatiri pack, masero akati wandei, mitsara inofambisa, mayuniti esampuli nezvimwe zvikamu zvekutsigira zvivakwa zvinobatanidzwa pamwe chete kuti zvigadzire module, inonziwo module.
Bhatiri reNingde Times CPT
CPT (cell to pack) ikubatanidzwa kwakananga kwemasero mubhatiri. Nekuda kwekubviswa kwekubatanidza kwebhatiri module, huwandu hwezvikamu zvebhatiri hunoderedzwa ne40%, huwandu hwekushandiswa kwehuwandu hwebhatiri reCTP hunowedzerwa ne15%-20%, uye kushanda zvakanaka kwekugadzira kunowedzerwa ne50%, izvo zvinoderedza zvakanyanya mutengo wekugadzira bhatiri remagetsi.
Ko mutengo webhatiri rebanga wakaita sei?
Tichitaura nezvemutengo, bhatiri re lithium iron phosphate pacharo harishandise simbi dzisingawanzoonekwi dzakadai se cobalt, mutengo wacho ndiwo mukana waro. Zvinonzwisisika kuti musika we ternary lithium battery cell we 2019 unopa pa 900 RMB / kW-h, nepo kupihwa kwe lithium iron phosphate battery cells pa 700 RMB / kW-h, mune ramangwana richanyorwa Han semuenzaniso, huwandu hwayo hunogona kusvika 605km, bhatiri re pack rinofungidzirwa kuti rinopfuura 80kW-h, kushandiswa kwemabhatiri e lithium iron phosphate kunogona kunge kuri 16,000 RMB (2355.3 USD) yakachipa. Fungidzira imwe mota itsva yemagetsi yemuno ine mutengo wakafanana ne BYD Han, bhatiri re pack rega rine mukana we 20,000 RMB (2944.16 USD), saka zviri pachena kuti ndeipi yakasimba kana isina simba.
Mune ramangwana, BYD Han EV ine mhando mbiri: mota imwe chete ine simba re163kW, 330N-m peak torque uye 605km NEDC range; mota mbiri ine simba re200kW, 350N-m maximum torque uye 550km NEDC range.
Musi wa12 Nyamavhuvhu, zvinonzi bhatiri reBYD rakaendeswa kuGigafactory Berlin yeTesla, iyo inotarisirwa kunge iine bhatiri remota dzeTesla dziri kunze kwemutsetse pakupera kwaNyamavhuvhu kusvika kutanga kwaGunyana pakutanga, nepo gigafactory yeTesla yeShanghai isina hurongwa hwekushandisa mabhatiri eBYD.
teslamag.de yakasimbisa kuti nhau idzi ndedzechokwadi. Mota yeModel Y ine mabhatiri eBYD inonzi yakagamuchira mvumo kubva kuEU, iyo yakapihwa neDutch RDW (Dutch Ministry of Transport) musi wa1 Chikunguru, 2022. Mugwaro iri, Mota itsva yeModel Y inonzi Type 005, ine bhatiri rinokwana 55 kWh uye daro remakiromita mazana mana nemakumi mana.
Ndezvipi zvakanakira mabhatiri ebanga
Zvakachengeteka:Mumakore achangopfuura, tsaona dzekuchengetedza mota dzemagetsi dzave dzichiitika kakawanda, uye zhinji dzacho dzinokonzerwa nemoto wemabhatiri. "Bhatiri reblade" rinogona kunzi ndiro rakanakisa pamusika. Sekureva kwekuyedza kwakabudiswa neBYD pakuedza kupinda kwechipikiri chebhatiri, tinogona kuona kuti "bhatiri reblade" mushure mekupinda, tembiricha yebhatiri inogonawo kuchengetedzwa pakati pe30-60 ℃, izvi zvinodaro nekuti dunhu rebhatiri reblade rakareba, nzvimbo yakakura uye kupisa kunokurumidza kupera. Ouyang Minggao, nyanzvi yezvedzidzo yeChinese Academy of Sciences, akataura kuti dhizaini yebhatiri reblade inoita kuti rigadzire kupisa kushoma uye ribvise kupisa nekukurumidza parinenge richipfupika, uye akaongorora mashandiro aro mu "bvunzo yekupinda kwechipikiri" seyakanaka kwazvo.
Simba rakawanda:Zvichienzaniswa nemabhatiri e-ternary lithium, mabhatiri e-lithium iron phosphate akachengeteka uye ane hupenyu hwakareba hwekutenderera, asi kare mubhatiri simba density rakadzvanywa musoro. Iye zvino blade battery wh/kg density kupfuura chizvarwa chekare chemabhatiri, kunyangwe kuwedzera kwe9% mu wh/l simba density, asi kuwedzera kusvika ku50%. Kureva kuti, "blade battery" bhatiri kugona kunogona kuwedzerwa ne50%.
Hupenyu hwebhatiri hurefu:Zvichienderana nekuyedza, hupenyu hwekuchaja bhatiri rebanga hunodarika ka4500, kureva kuti kuora kwebhatiri kushoma pane 20% mushure mekuchaja ka4500, hupenyu hwebhatiri hunodarika ka3 pane ternary lithium battery, uye hupenyu hwemakiromita akaenzana ebhatiri rebanga hunogona kupfuura 1.2 miriyoni km.
Nzira yekuita basa rakanaka pamusoro peganda remukati, ndiro yekutonhodza, chifukidziro chepamusoro nechepasi, tireyi, baffle nezvimwe zvinhu kuti uwane zvinodiwa zvekuchengetedza zvekudzivirira kupisa, kudzivirira kupisa, kudzoreredza moto, kusingatsvi uye kusangana nezvinodiwa zvekugadzira otomatiki? Ndiro dambudziko guru nebasa refekitori yekuputira munguva itsva.
