Motokari dzemagetsi dzinoda rudzii rwebhatiri remagetsi? Mubvunzo uyu, unoita seusingade kupindurwa, uchangobva kutonga kufunga kwevanhu nekuda kwenyaya inopisa nezve “gakava rehunyanzvi pakati pemabhatiri e-ternary lithium uye lithium iron phosphate mabhatiri”.

Hapana mubvunzo nezve “kuchengetedzwa kwekutanga” chero nguva. Nekudaro, sezvatinoziva tese, mumakore mashoma apfuura, nekuti makambani mazhinji akawira muupofu kuenzanisa kwe “endurance range”, inherent thermal kugadzikana kwakashata, asi ternary lithium bhatiri ine yakakwirira simba density kupfuura lithium iron phosphate. bhatiri rinotsvakwa zvakanyanya. Mukurumbira wekuchengetedza motokari nekudaro wakabhadhara mutengo unorema zvakanyanya.

Musi waKurume 29, 2020, BYD yakaparura zviri pamutemo bhatiri reblade, ichizivisa kuti rwendo rwayo rwasvika padanho rakafanana neiyo ternary lithium bhatiri, uye yapfuura iyo inotyisa “acupuncture test” muindasitiri yemagetsi bhatiri. Muedzo wekuchengeteka wakaoma sekukwira Everest.

Iyo blade bhatiri inopika kutsanangura patsva chiyero chekuchengetedza mota yemagetsi inogadzirwa sei?

Musi wa4 Chikumi, chiitiko chakavanzika chefekitori chine dingindira rekuti “Kukwira Peak” chakaitwa paChongqing fekitori yeFordi Battery. Vanopfuura zana vezvenhau nenyanzvi dzeindasitiri vakashanyira saiti. Fekitori yepamusoro kuseri kwebhatiri reblade yakavhurwawo.

Kunyanya kutsvaga kwesimba density, iyo magetsi bhatiri indasitiri inoda kururamiswa nekukurumidza

Kusati kwauya bhatiri reblade, dambudziko rekuchengetedza bhatiri rave nyaya yakagara kwenguva refu munyika.

Kuchengetedzeka kwebhatiri remotokari dzemagetsi kunowanzo reva kudziya kwebhatiri. Kuenzaniswa nemabhatiri maviri akajairika anowanzoshandiswa mumotokari dzemagetsi pari zvino, iyo lithium iron phosphate zvinhu pachayo ine mabhenefiti mana makuru ekupisa kupisa kwekutanga kupisa, kunonoka kuburitsa kupisa, kushoma kugadzirwa kwemagetsi, uye zvinhu hazvibudise okisijeni panguva yekuora. process uye haisi nyore kubata moto. Kusagadzikana kwemafuta uye kuchengetedzeka kweternary lithium mabhatiri ichokwadi chinozivikanwa neindasitiri.

“Pakupisa kwe500 ° C, chimiro chelithium iron phosphate zvinhu chakanyatsogadzikana, asi ternary lithium zvinhu zvichaora paanenge 200 ° C, uye kemikari inogadzirisa inowedzera chisimba, inosunungura mamolekemu eokisijeni, uye ichaita. zviri nyore kukonzera kupisa kutiza.” Sun Huajun, mutevedzeri wemaneja weDi Battery Company, akadaro.

Nekudaro, kunyangwe maererano nekuchengetedza, lithium iron phosphate mabhatiri ane mabhenefiti asingaenzaniswi pamusoro pe ternary lithium mabhatiri, asi nekuda kwekuti simba remagetsi rakaderera pane iro re ternary lithium, makambani mazhinji emotokari dzevatyairi akawira mukunetseka kusingaite pamusoro pesimba remagetsi emagetsi mabhatiri. makore mashoma apfuura. Tichitevera, iyo lithium iron phosphate bhatiri yakanga ichiri kukundwa mune yekupedzisira mafungu emakakatanwa emutsara neiyo ternary lithium bhatiri.

Wang Chuanfu, Sachigaro weBYD Group, anozivikanwa se “Battery King”, akatanga sebhatiri. Kusati kwaziviswa kwekugadzirwa kwemotokari kuyambuka muganhu muna 2003, kutsvagisa nekuvandudzwa kwemabhatiri emagetsi emotokari kwakange kwatotanga. Kubva pakatangwa bhatiri remagetsi rekutanga kusvika pakuva imwe yemhando huru dzemotokari dzepasi rose, BYD yagara ichiisa “chengetedzo” munzvimbo yekutanga.

Izvo zvakanyatsoenderana nekukosha kwakanyanya kwekuchengetedza iyo BYD haina kumbosiya kuvandudzwa kwe lithium iron phosphate mabhatiri kunyangwe munzvimbo yemusika umo ternary lithium mabhatiri ave achiremekedzwa zvakanyanya mumakore mashoma apfuura.

Kutsanangudza mitemo yekuchengetedza, kudhinda “acupuncture test”

Iyo blade bhatiri yakazvarwa, uye iyo indasitiri yakataura kuti nzira yekuvandudza yemagetsi bhatiri indasitiri iyo yave isiri munzira kwemakore mazhinji pakupedzisira ine mukana wekudzoka munzira.

“Kuchengetedzeka kukuru” ndicho chinhu chikuru chebhatiri reblade. Panyaya iyi, iyo acupuncture test, inozivikanwa se “Mount Everest” munharaunda yemagetsi ekuchengetedza bhatiri, yakadhindwa pairi. Uye zvakare, blade bhatiri inewo simba repamusoro, super bhatiri hupenyu, yakanyanya kuderera tembiricha, super hupenyu, super simba uye super performance uye “6S” tekinoroji pfungwa.

Mabhatiri ega ane urefu hwe 96 cm, hupamhi hwe 9 cm, uye urefu hwe 1.35 cm akarongwa mumutsara uye akaiswa mubhatiri pack se “blade”. Iwo ma modules uye matanda anoregwa kana achigadzira boka, izvo zvinoderedza Mushure mezvimedu zvisingaverengeki, chimiro chakafanana nehoneycomb aluminium plate inoumbwa. Kuburikidza nenhevedzano yezvimiro zvekuvandudza, blade bhatiri yakawana simba repamusoro rebhatiri, nepo kuchengetedza kwebhatiri pack kwakavandudzwa zvakanyanya, uye huwandu hwekushandisa vhoriyamu hwakawedzerawo ne50%. kumusoro.

“Nekuti blade bhatiri rinogona kudzikisa zvakanyanya zvikamu zvemukati zvakawedzerwa neternary lithium bhatiri nekuda kwekusakwana kwebhatiri kuchengetedzeka uye simba, nekudaro kuderedza huremu hwemotokari, simba redu rimwe chete harina kukwira kupfuura iro reternary lithium, asi rinogona kusvika. iyo mainstream ternary lithium bhatiri. Lithium mabhatiri ane kutsungirira kwakafanana. ” Sun Huajun akazivisa.

“Yekutanga BYD Han EV ine mabhatiri eblade ine rwendo rwemakiromita 605 pasi pemamiriro ekushanda akazara,” akadaro Li Yunfei, mutevedzeri wemaneja mukuru weBYD Auto Sales.

Pamusoro pezvo, bhatiri reblade rinogona kuchaja kubva pa10% kusvika pa80% mumaminetsi makumi matatu nematatu, rinotsigira 33 makiromita kukwira mumasekonzi 100, rinogona kufamba makiromita 3.9 miriyoni neanopfuura mazana matatu emakumi matatu ekuchaja nekuburitsa, uye kuita kwedata senge kuderera kwekushisa kuita kupfuura. fungidziro yeindasitiri. Kuti uwane “super advantage” yeayo-akapoteredza “rolling” ternary lithium bhatiri.

Fekitori yepamusoro inodudzira Indasitiri 4.0, ichivanza chakavanzika che “peak kumusoro” yebhatiri reblade.

Musi waChivabvu 27, nhau yekuti 8 nhengo dzechikwata cheChinese dzakabudirira kukwira Gomo reEverest zvakaita kuti vanhu vekuChina vanzwe kufara zvikuru, uye kusvetuka kweBYD kwepamusoro pekuchengetedza bhatiri kwakamutsawo kunetseka kwakapararira uye nhaurirano dzinopisa mumunda wemotokari dzemagetsi.

Zvakaoma sei kusvika pamusoro pe “Mount Everest” mune simba rekuchengetedza bhatiri nyika? Takashanyira fekitori yeFudi Battery’s Chongqing tikawana mhinduro.

Iyo Fudi bhatiri fekitori muBishan District, Chongqing parizvino ndiyo yega nzvimbo yekugadzira yemabhatiri eblade. Fekitori iyi ine mari inosvika mabhiriyoni gumi emayuan uye yakarongwa gore negore huwandu hwekugadzira 10GWH. Kubva pakatanga kuvakwa muna Kukadzi 20 uye kuvhurwa zviri pamutemo kwebhatiri reblade munaKurume 2019, yachinja kubva munzvimbo yakavhurika kuita fekitori yepasi rose ine yakaonda, otomatiki, uye ruzivo-yakavakirwa magadzirirwo ekugadzira system mugore rimwe chete. . Yakawanda yeBYD yekutanga blade bhatiri mitsara yekugadzira uye zvigadzirwa zvekugadzira zvakazvarwa pano, uye akati wandei akavanzika epakati matekinoroji “akavanzwa”.

“Chekutanga, zvinodikanwa zvenzvimbo yekugadzira mabhatiri eblade zvakanyanya kudiwa.” Sun Huajun akataura kuti kudzikisa kupfupi-kutenderera chiyero chemabhatiri, ivo vakakurudzira pfungwa yeguruva classification control. Mune mamwe maitiro akakosha, vanogona kuwana imwe-stop solution. Munzvimbo yemamita, hapana anopfuura makumi maviri nemapfumbamwe zvidimbu zve29 microns (bvudzi kureba 5/1 ukobvu), iyo inosangana neyakafanana chiyero seLCD skrini yekugadzira workshop.

Nzvimbo yakaoma uye mamiriro ezvinhu anongova “nheyo” yekuvimbisa kuchengetedzwa kwepamusoro kwemabhatiri eblade. Sekureva kwaSun Huajun, kuomerwa kukuru uye nzvimbo inopenya mukugadzirwa kwemabhatiri eblade inonyanya kutariswa mu “maitirwo makuru masere.”

“Chidimbu chine hurefu hunosvika 1 mita chinokwanisa kuwana kushivirira kutonga mukati me ± 0.3mm uye iko kurongeka uye nekumhanya kwekamwe-chidimbu lamination kunyatsoshanda pa 0.3s/pcs. Tisu vekutanga munyika. Iyi lamination inotora BYD Iyo yakazvimiririra yakagadziridzwa michina uye chirongwa chekucheka hachigone kuteedzerwa nemumwe munhu anoda kutevedzera. ” Sun Huajun akadaro.

Pamusoro pelamination, iyo batching, coating, rolling, kuyedza uye mamwe maitiro mublade bhatiri yekugadzira maitiro asvika padanho repamusoro repasi. Semuenzaniso, kururamisa kweiyo batching system iri mukati me0.2%; mativi ese ari maviri akaputirwa panguva imwe chete, iyo yakakura yekupfekedza hupamhi ndeye 1300mm, uye iyo coating uremu kutsauka pane imwe unit nzvimbo isingasviki 1%; iyo yekumhanyisa kumhanya ye1200mm yekupedzisira-yakafara upamhi inogona kusvika 120m/min, uye ukobvu hunodzorwa. Mukati me2μm, kuve nechokwadi chekuenderana kwehukobvu hwehupamhi-saizi yedanda chidimbu ……

Yese blade bhatiri inozvarwa kubva kusingaverengeki kutsvaga kwekukwana! Muchokwadi, hunyanzvi uye maitiro senge “pamusoro pezvakanakisa” anobva kuindasitiri 4.0-chikamu chekugadzira uye manejimendi system yeblade bhatiri fekitori.

Yepamusoro-chaiyo sensors mukati memusangano wekugadzira, maitiro, uye mitsara, mazana emarobhoti, uye yemhando yekudzora sisitimu inosangana neIATF16949&VDA6.3 control standard, nezvimwewo, inogonesa otomatiki yemidziyo yezvirimwa Hardware uye ruzivo rwemidziyo nemidziyo. Uchenjeri hwezinga rekutonga rave rakasimba “kutsigira” kwehutano hunobudirira uye hwakagadzikana hwekugadzirwa kwebheteri yeblade.

“Ichokwadi, chimwe nechimwe chezvigadzirwa zvedu zvebhatiri reblade zvakare chine kadhi reID rakasarudzika. Mune ramangwana, data rakasiyana-siyana panguva yekushandiswa kwechigadzirwa richatipawo chirevo chakakosha chekuenderera mberi kwekuvandudza kwemaitiro uye chigadzirwa chakakwana. ” Sun Huajun akati, Ford Battery Chongqing chirimwa ndiyo fekitori yekutanga pasi rose yemabhatiri eblade. Nekuwedzera kunoramba kuchiwedzera kwesimba rekugadzira, mabhatiri eblade achavhurika kune iyo itsva simba indasitiri yemotokari yekugovana, kubatsira indasitiri nevatengi, uye kubatsira kusimudzira kwepasi rose mota dzemagetsi kupinda munguva itsva.

“Nhasi, dzinenge mhando dzese dzemotokari dzaungafunga nezvadzo dziri kukurukura nezve hurongwa hwekushandira pamwe hunoenderana nesu blade bhatiri tekinoroji.” Akati.

Uye nhasi tagadzira imwe bhatiri paki yeE marines, E yatchs, E mabhoti ……
