Cov roj teeb lithium hlau phosphate sim dhau NMC lithium roj teeb
Txij li thaum nws tso tawm xyoo tas los, qhov nrov ntawm BYD hniav roj teeb tau khaws cia nyob rau theem siab, uas tau ua rau BYD tsav lub lithium hlau phosphate roj teeb kev lag luam yuav luag ntawm nws tus kheej.
Hauv thawj peb lub hlis twg ntawm lub xyoo no, tus nqi ntawm lithium hlau phosphate cov ntaub ntawv tau nce 29.73%, thiab ze li ntawm 30% nce tuaj yeem ua pov thawj qhov kev xav tau ntawm cov roj teeb ntawm sab.
Qhov nce hauv kev thov yog ib txwm muaj vim qhov nce hauv cov qauv nruab nrog cov roj teeb pob.
Lub Plaub Hlis 7, ntawm lub rooj sib tham xov xwm loj, BYD tshaj tawm tias tag nrho nws cov qauv hluav taws xob yuav nruab nrog cov roj teeb, thiab tso tawm 2021 Tang EV, Qin PLUS EV, Song PLUS EV, thiab 2021 e2 nrog cov roj teeb hniav. Plaub lub tsheb tshiab. Tib lub sijhawm, BYD kuj tau tshaj tawm tias nws yuav siv tag nrho kev kuaj mob acupuncture raws li tus qauv kev lag luam.
Qhov tseeb, piv rau kev tso tawm cov tsheb tshiab, kev siv tag nrho ntawm kev kuaj mob acupuncture raws li tus qauv kev lag luam yog qhov tseem ceeb ntawm BYD lub rooj sib tham xov xwm. Los ntawm BYD tus thawj coj Wang Chuanfu nws tus kheej ntawm lub platform thiab hais tias “kev nyab xeeb yog qhov khoom kim tshaj plaws ntawm cov tsheb hluav taws xob”, nws tsis yooj yim pom tias BYD tau rov xa cov teeb liab tseem ceeb rau lub ntiaj teb sab nraud: cov roj teeb hniav muaj kev nyab xeeb dua.
Los ntawm thawj hnub ntawm kev yug me nyuam ntawm cov hniav roj teeb, Wang Chuanfu’s BYD tau txhawb nqa cov hniav roj teeb nrog “kev nyab xeeb” raws li qhov muag. Txawm hais tias nyob rau hauv cov ntsiab lus ntawm cov yam ntxwv roj teeb, lub lithium hlau phosphate roj teeb siv nyob rau hauv cov hniav roj teeb yog qis dua rau cov nqi kim tshaj ternary lithium roj teeb nyob rau hauv cov nqe lus ntawm lub zog ceev thiab kub tsis tshua muaj peev xwm, yog li nws muaj qhov tsis zoo me ntsis ntawm “kev ua siab ntev” thiab “tsis tshua muaj kub ib puag ncig kev ua haujlwm”. Tab sis nyob rau hauv cov nqe lus ntawm durability, tus nqi tswj, kub tsis kam thiab kev nyab xeeb, lithium hlau phosphate roj teeb muaj ntau qhov zoo. Tshwj xeeb, nws ruaj khov dua thaum them nyiaj ceev thiab tsis muaj kev pheej hmoo ntawm kev tawg thaum raug cuam tshuam. Ob lub ntsiab lus no yuav luag dhau los ua “killer” ntawm lithium phosphate roj teeb. Cov yam ntxwv zoo no kuj tau ua rau BYD ntxiv dag zog rau txoj hauv kev ntawm lithium hlau phosphate roj teeb.
Txhawm rau kom txhua tus neeg nkag siab tob ntxiv txog kev nyab xeeb ntawm cov roj teeb hluav taws xob, ntawm lub rooj sib tham xov xwm, Wang Chuanfu tau muab lub tswv yim zoo thiab muaj tseeb: Nrog rau kev nce zuj zus ntawm kev nkag mus ntawm lub zog tshiab tsheb yav tom ntej, lub zog tshiab tsheb nruab nrog lithium. roj teeb yuav tshwm sim hauv kev khiav tsheb. Qhov tshwm sim ntawm kev sib tsoo yuav nce ntxiv. Yog hais tias lub qhov rooj yog deformed thiab tsis tuaj yeem qhib thaum muaj xwm txheej loj, thiab “kev ruaj ntseg ntawm lub hwj chim roj teeb tsis siab, thiab qhov tshwm sim ntawm combustion thiab hluav taws xob tsim tshwm sim, qhov tshwm sim yuav tsis xav txog.” Kev txiav txim los ntawm qhov kawg ntawm kev sib tsoo ntawm lub tsheb hluav taws xob hauv xyoo tas los no, Wang Chuanfu qhov kev xav tsis yog qhov tsis tsim nyog.
Kev xaiv ntawm kev ua lag luam muab BYD kev ntseeg siab ntau dua.
Raws li cov ntaub ntawv los ntawm Tuam Tshoj Association of Automobile Manufacturers thiab Lub Tuam Txhab Kev Tshawb Fawb Kev Lag Luam Kev Lag Luam, ternary lithium roj teeb muaj tag nrho 38.9GWh, suav txog 61.1%, thiab nce ntxiv ntawm 4.1%. Lithium hlau phosphate roj teeb tau teeb tsa 24.4GWh, suav txog 38.3%. Qhov nce ntxiv yog 20.6%.
Txawm li cas los xij, nyob rau lub Kaum Ob Hlis xyoo tas los, lub zog hluav taws xob hauv tsev tau teeb tsa muaj peev xwm yog 13GWh, ib xyoos ib zaug nce ntawm 33.4%. Ntawm lawv, ternary lithium roj teeb muaj tag nrho 6GWh, ib xyoos ib zaug nce ntawm 24.9%, thiab lithium hlau phosphate roj teeb muaj tag nrho 6.9GWh, ib xyoos ib zaug nce ntawm 45.5%. Paub txog qhov ua ntej mus rau ternary lithium roj teeb.
Kev nce ntau hauv kev thauj khoom ntawm lithium hlau phosphate roj teeb yog sib cais los ntawm kev muag khoom kub ntawm cov qauv roj teeb uas sawv cev los ntawm BYD Han.
Txij li thaum nws tso tawm xyoo tas los, BYD Han qhov muag tau maj mam ruaj khov ntawm qhov nruab nrab txhua hli ntawm 10,000 lub tsheb. Raws li lub tsheb loj loj nrog cov khoom lag luam ywj pheej uas muag rau ntau dua 200,000 yuan, nws tsis tshua muaj qhov ua tau zoo li no.
Ntawm lub rooj sib tham xov xwm no, BYD kuj tau tshaj tawm “kev sim tsheb hnyav” thawj zaug. Cov neeg xeem tau muab tshem tawm cov roj teeb ntawm Han EV. Tom qab lub tsheb hnyav 46-tuj dov, lub roj teeb pob tsis yog tsuas yog muaj kev nyab xeeb thiab lub suab, tab sis kuj rov nruab. Tom qab lub tsheb qub, Han EV tseem tuaj yeem tsav tau ib txwm. Txawm hais tias qhov no yog BYD’s “invented” project project, qhov tseeb qag load ntawm lub roj teeb tsis yog tag nrho 46 tons (kwv yees tsis pub tshaj 20 tons), tab sis nws tuaj yeem pom tau tias cov hniav roj teeb muaj lub zog thiab kev sib tsoo. Kev ntseeg siab.
Hais txog cov hniav roj teeb, Wang Chuanfu zoo siab hais tias: “Tom qab tso tawm cov roj teeb, yuav luag txhua lub tsheb hom koj tuaj yeem xav txog yog kev sib tham nrog Fordy Battery.” Tsis tas li ntawd, nws kuj tau hais tias tam sim no cov hniav roj teeb tsim muaj peev xwm nce sai. Po, thiab yuav pib muab rau tag nrho cov kev lag luam nyob rau hauv ib nrab ntawm lub xyoo no.
Txawm hais tias tsuas yog qhib tus khub yog lub npe Hongqi, “nyob rau hauv lub neej yav tom ntej, txhua tus neeg yuav tuaj yeem pom cov roj teeb, uas yuav txuas ntxiv mus rau lub zog tshiab ntawm cov khoom tseem ceeb hauv tsev thiab txawv teb chaws.”
Thaum Lub Plaub Hlis 2, Li Yunfei, tus lwm thawj tswj hwm ntawm BYD Automobile Sales Co., Ltd., tau hais tias qhov muaj peev xwm ntawm kev nthuav dav kev lag luam los ntawm cov npe ntawm Verdi roj teeb tsis tuaj yeem txiav tawm.
Kev muag cov roj teeb rau cov tuam txhab uas xav tsim tsheb yog undoubtedly ib lub lag luam zoo, tab sis vim yog cov yam ntxwv ntawm lithium hlau phosphate roj teeb, tam sim no nws yog ib qho nyuaj rau nce lub cruising ntau npaum li cas yam tsis muaj ho nce lub luj ntawm lub roj teeb.
Txawm li cas los xij, BYD tau pom tseeb tias muaj kev ntseeg siab rau yav tom ntej ntawm cov roj teeb hniav.
Raws li cov ntaub ntawv raug cai, BYD Verdi Battery tam sim no muaj rau lub hauv paus tsim khoom hauv Chongqing, Shenzhen, Xi’an, Qinghai, Changsha thiab Guiyang. Ntawm lawv, Verdi Battery Chongqing Cog yog lub ntiaj teb thawj cov hniav roj teeb cog nrog lub peev xwm ntawm 20GWh; Changsha cog yog thawj zaug hauv ntiaj teb. Cov hniav roj teeb cov kab ntau lawm kuj tau muab tso rau hauv kev ua haujlwm thaum kawg ntawm 2020, nrog rau tsim txhua xyoo muaj peev xwm ntawm 20GWh; Tsis tas li ntawd, qhov project Bengbu Fordy nrog kev nqis peev ntawm 6 billion yuan tau pib tsim, nrog rau kev npaj txhua xyoo muaj peev xwm ntawm 10GWh hauv thawj theem; Guiyang cog kuj tseem yuav muab tso rau hauv kev ua haujlwm hauv xyoo 2012. Raws li BYD txoj kev npaj, tag nrho cov peev txheej ntawm cov roj teeb yuav tsum ncav cuag 75GWh thaum kawg ntawm 2021, thiab lub peev xwm yuav nce ntxiv mus rau 100GWh thaum kawg ntawm 2022.
