Sei BYD blade bhatiri ikozvino nyaya inopisa
BYD's "blade bhatiri", iyo yave ichikakavadzana zvakanyanya muindasitiri kwenguva yakareba, yakazoburitsa chimiro chayo chechokwadi.
Zvichida munguva pfupi yapfuura vanhu vazhinji vanga vachinzwa izwi rekuti "blade bhatiri", asi pamwe vasinganyatso kujairana nazvo, saka nhasi tichatsanangura nezve "blade bhatiri" zvakadzama.
Ndiani akatanga kukumbira blade bhatiri
Sachigaro weBYD Wang Chuanfu akazivisa kuti BYD "blade bhatiri" (chizvarwa chitsva che lithium iron phosphate mabhatiri) ichatanga kugadzirwa kwemazhinji muChongqing fekitori munaKurume gore rino, uye muna Chikumi yakanyorwa muHan EV Kekutanga kutakura. Ipapo BYD yakarova zvakare misoro yemotokari uye kunyange zvikamu zvezvemari zvemapuratifomu makuru enhau.
Nei Blade Battery
Iyo blade bhatiri inoburitswa neBYD musi waKurume 29, 2020. Zita rayo rakazara inonzi blade type lithium iron phosphate battery, inozivikanwawo se "super lithium iron phosphate battery". Iyo bhatiri inoshandisa lithium iron phosphate tekinoroji, ichatanga yakashongedzerwa neiyo BYD "Han" modhi.
Kutaura zvazviri, "blade bhatiri" chizvarwa chitsva lithium iron phosphate bhatiri ichangoburwa neBYD, chokwadi, BYD yave yakatarisana nekuvandudzwa kwe "super lithium iron phosphate" kuburikidza nemakore akawanda ekutsvakurudza , zvichida mugadziri anotarisira kuti kuburikidza nezita rakapinza uye rinenge riri redimikira, kuwana tarisiro yakawanda uye pesvedzero.
Blade bhatiri chimiro dhizaini
Kuenzaniswa neBYD yapfuura lithium iron phosphate bhatiri, kiyi ye "blade bhatiri" inogadzirwa pasina module, yakanyatso kubatanidzwa mubhatiri pack (kureva CTP tekinoroji), nekudaro ichivandudza zvakanyanya kubatanidzwa kwekuita.
Asi chokwadi, BYD haisi yekutanga kugadzira kushandisa CPT tekinoroji. Seyakakura pasirese yakaiswa simba rekugadzira bhatiri, Ningde Times yakashandisa CPT tekinoroji pamberi peBYD. munaGunyana 2019, Ningde Times yakaratidza tekinoroji iyi muFrankfurt Motor Show.
Tesla, Ningde Times, BYD uye Hive Energy, vatanga kuvandudza uye vakazivisa kuti vachawanda kugadzira zvigadzirwa zvine chekuita neCTP, uye module-isina simba bhatiri mapaketi ari kuita nzira yetekinoroji.
Traditional ternary lithium bhatiri pack
Iyo inonzi module, chikamu chezvikamu zvakakosha zvinoumba module, inogona zvakare kunzwisiswa sepfungwa yezvikamu musangano. Mundima iyi yebhatiri pack, akati wandei masero, conductive mitsara, sampling mauniti uye zvimwe zvinodiwa zvimiro zvekutsigira zvinobatanidzwa pamwe chete kugadzira module, inonziwo module.
Ningde Times CPT bhatiri paki
Iyo CPT (sero kurongedza) ndiko kusanganisa kwakananga kwemasero mubhatiri pack. Nekuda kwekubviswa kwebhatiri module yekubatanidza link, nhamba yebhatiri pack zvikamu zvakaderedzwa ne40%, huwandu hwekushandisa vhoriyamu yeCTP bhatiri pack inowedzerwa ne15% -20%, uye kugona kwekugadzira kunowedzerwa ne50%, iyo inoderedza zvakanyanya mari yekugadzira yebhatiri remagetsi.
Zvakadini nemutengo weblade bhatiri
Kutaura nezve mutengo, lithium iron phosphate bhatiri pachayo haishandise simbi isingawanzo se cobalt, mutengo ndiwo mukana wayo. Zvinonzwisiswa kuti 2019 ternary lithium bhatiri cell musika inopa anenge 900 RMB / kW-h, nepo kupihwa kwe lithium iron phosphate bhatiri masero paanenge 700 RMB / kW-h, mune ramangwana ichave yakanyorwa Han semuenzaniso, yayo. huwandu hunogona kusvika 605km, bhatiri pack inofanotaurwa kuva inopfuura 80kW-h, kushandiswa kwe lithium iron phosphate mabhatiri inogona kunge iri 16,000 RMB (2355.3 USD) yakachipa. Fungidzira imwe mota nyowani yemumba ine mutengo wakafanana uye wemhando seBYD Han, bhatiri paki yega ine mutengo mukana we20,000 RMB(2944.16 USD), saka zviri pachena kuti ndeipi yakasimba kana isina simba.
Mune ramangwana, BYD Han EV ine shanduro mbiri: single-motor version ine 163kW simba, 330N-m peak torque uye 605km NEDC range; dual-motor version ine simba re200kW, 350N-m maximum torque uye 550km NEDC range.
Musi waNyamavhuvhu 12, zvinonzi, BYD's blade bhatiri yakaunzwa kuTesla's Gigafactory Berlin, iyo inotarisirwa kuve yakashongedzerwa nebhatiri Tesla mota kubva pamutsetse pakupera kwaNyamavhuvhu kusvika kutanga kwaGunyana pakutanga, nepo Tesla's Shanghai gigafactory. haina zvirongwa zvekushandisa mabhatiri eBYD.
teslamag.de yakasimbisa huchokwadi hwenhau. Model Y ine mabhatiri eBYD inonzi yakagamuchira mvumo yerudzi kubva kuEU, iyo yakapihwa neDutch RDW (Dutch Ministry of Transport) musi waChikunguru 1, 2022. Mugwaro iri, Model Y itsva inonzi Type 005, ine bhatiri rinokwana 55 kWh uye kureba kwe440 km.
Ndezvipi zvakanakira mabhatiri eblade
Kwakachengeteka:Mumakore achangopfuura, tsaona dzekuchengetedza motokari dzemagetsi dzave dzichiwanzoitika, uye dzakawanda dzadzo dzinokonzerwa nemoto webhatiri. Iyo "blade bhatiri" inogona kunzi ndiyo yakanyanya kuchengetedzwa pamusika. Maererano neBYD yakadhindwa ongororo pabhatiri mbambo yekupinda bvunzo, tinogona kuona kuti "blade bhatiri" mushure mekupinda, tembiricha yebhatiri inogonawo kuchengetedzwa pakati pe30-60 ℃, izvi imhaka yekuti blade bhatiri redunhu rakareba, rakakura nzvimbo uye nekukurumidza kupisa. dissipation. Ouyang Minggao, mudzidzi weChinese Academy of Sciences, akataura kuti dhizaini yebhatiri reblade inoita kuti igadzire kupisa kushoma uye kubvisa kupisa nekukurumidza kana ipfupi-inotenderera, uye akaongorora mashandiro ayo mu "nail kupinda bvunzo" yakanaka.
High energy density:Kuenzaniswa ne ternary lithium mabhatiri, lithium iron phosphate mabhatiri akachengeteka uye ane hupenyu hurefu hwekutenderera, asi kare mubhatiri simba density yakatsikirirwa musoro. Iye zvino blade bhatiri wh / kg density kupfuura chizvarwa chekare chebhatiri, kunyange iyo 9% inowedzera mu wh / l simba density, asi kuwedzera kusvika ku50%. Ndiko kuti, "blade bhatiri" bhatiri kugona kunogona kuwedzerwa ne50%.
Hupenyu hurefu hwebhatiri:Zvinoenderana nekuyedza, iyo blade bhatiri yekuchaja kutenderera hupenyu hunopfuura 4500 nguva, kureva kuora kwebhatiri iri pasi pe20% mushure me4500 nguva yekuchaja, hupenyu hunodarika 3 nguva dze ternary lithium bhatiri, uye yakaenzana mileage hupenyu hweblade bhatiri inogona. kupfuura 1.2 mamiriyoni km.
Maitiro ekuita basa rakanaka pamusoro peiyo core shell, inotonhorera ndiro, yekumusoro uye yezasi chivharo, tireyi, baffle uye zvimwe zvinhu kuti uwane zvinodiwa zvekuchengetedza zvekudzivirira, kupisa kupisa, kudzoreredza moto, kusapisa moto uye kusangana nezvinodiwa zvekugadzira otomatiki. ? Ndiro dambudziko guru uye mutoro wefekitari yekuputira munguva itsva.
