Kuchaja kwemaminetsi mashanu nehupamhi hwemakiromita mazana mana! Musi waKurume 17, BYD yakaburitsa "megawatt flash charging" system, iyo inogonesa mota dzemagetsi kuchaja nekukurumidza sekuwedzera mafuta.
Zvisinei, kuitira kuzadzisa chinangwa che "mafuta nemagetsi pamwero wakafanana", BYD inoratidzika kunge yasvika pakuguma kwayo lithium iron phosphate bhatiri. Kunyangwe idi rekuti simba remagetsi relithium iron phosphate zvinhu pachayo rave kusvika painogumira dzidziso, BYD ichiri kusundira chigadzirwa dhizaini uye tekinoroji optimization kusvika yakanyanyisa.
Tamba kusvika pakunyanyisa! 10C lithium iron phosphate
Chekutanga, maererano neruzivo rwakaburitswa pamusangano wenhau weBYD, tekinoroji yekuchaja tekinoroji yeBYD inoshandisa chigadzirwa chinonzi "flash charging blade bhatiri", iyo ichiri rudzi rwe lithium iron phosphate bhatiri.
Izvi hazvisi kungoputsa hutongi hwehuwandu hwemabhatiri e-lithium akadai seyepamusoro nickel ternary mabhatiri mumusika wekukurumidza kuchaja, asi zvakare inobvumira BYD kusundira kushanda kwelithium iron phosphate kune yakanyanyisa zvakare, ichibvumira BYD kuenderera mberi kukosha kwayo kwemusika munzira yehunyanzvi ye lithium iron phosphate mabhatiri.
Zvinoenderana nedata rakaburitswa neBYD, BYD yakawana peak yekuchaja simba re1 megawatt (1000 kW) kune mamwe mamodheru akadai seHan L neTang L, uye flash charge yemaminetsi mashanu inogona kuwedzera mazana mana emakiromita. Yayo' flash kuchaja 'bhatiri yasvika pakuchaja kwe10C.
Pfungwa ipi iyi? Panyaya yemisimboti yesainzi, parizvino inozivikanwa muindasitiri kuti simba density yelithium iron phosphate mabhatiri ari padyo neiyo theoretical limit. Kazhinji, kuitira kuti ive nechokwadi chepamusoro simba density, vagadziri vanopira imwe yechaji yavo uye nekuburitsa kuita. Kazhinji, 3-5C yekubuda inoonekwa seyakanaka yekuburitsa mwero welithium iron phosphate mabhatiri.
Zvisinei, panguva ino BYD yakawedzera kubudiswa kweti lithium iron phosphate kusvika 10C, izvo zvisingarevi chete kuti ikozvino inenge yakapetwa kaviri, asi zvinorevawo kuti kupikisa kwemukati uye kuoma kwekupisa kwekushisa kwakapetwa kaviri.
BYD inotaura kuti pahwaro hweblade, BYD's "flash kuchaja bhatiri" inokwenenzvera chimiro che electrode yebhatiri rebheti, kuderedza kutama kwe lithium ions ne50%, nekudaro kuwana chiyero chekuchaja chinodarika 10C kekutanga.
Pamusoro pezvinhu zvakanaka zve electrode, BYD inoshandisa high-purity, high-pressure, uye high-density yechizvarwa chechina lithium iron phosphate zvinhu, pamwe chete nanoscale crushing process, special formula additives, uye high-temperature calcination process. Iyo yakanyanya kukwana yemukati mekristaro chimiro uye ipfupi diffusion nzira yelithium ion inowedzera kutama kwerithium ions, nekudaro ichidzikisa bhatiri mukati kuramba uye kuvandudza chiyero chekubuda.
Mukuwedzera, maererano nekusarudzwa kwema electrode asina kunaka uye electrolytes, zvinodiwawo kusarudza zvakanakisisa kubva kune zvakanakisisa. Kuiswa kweartificial graphite ine yakakwirira chaiyo nzvimbo uye kuwedzerwa kwepamusoro-performance PEO (polyethylene oxide) maelectrolyte avewo mamiriro anodiwa kutsigira 10C lithium iron phosphate mabhatiri.
Muchidimbu, kuti uwane kubudirira kwekuita, BYD inochengetedza hapana muripo. Pamusangano wevatori venhau, mutengo weBYD Han L EV wakashongedzerwa nebhatiri re "flash charging" wasvika 270000-350000 yuan, iyo ingangoita 70000 yuan yakakwira kupfuura mutengo weiyo 2025 EV yakangwara yekutyaira shanduro (701KM Honor modhi).
Ndeipi nguva yehupenyu uye kuchengetedzeka kwemabhatiri ekuchaja flash?
Zvechokwadi, kune yepamusoro-tech, kudhura haisi dambudziko. Munhu wose achiri kunetseka nezvehutano uye kuchengeteka kwechigadzirwa.Nezveizvi, Lian Yubo, Mutevedzeri Mukuru weBYD Group, akataura kuti mabhatiri ekuchaja anogona kuchengetedza hupenyu hurefu kunyange kana achipomerwa pa-ultra-high rates, ne 35% kuwedzera kwehupenyu hwebhatiri.
Zvinogona kutaurwa kuti mhinduro yeBYD panguva ino yakanaka uye izere nehunyanzvi, zvirinani kwete kuramba kukanganisa kwekuchaja pahupenyu hwebhatiri.
Nekuti musimboti, kukurumidza kuchaja uye kuburitsa kuchave nemhedzisiro isingadzoreki pane bhatiri chimiro. Iko kukurumidza kuchaja nekumhanyisa kumhanya, ndiko kuwedzera kukanganiswa kwehupenyu hwebhatiri. Kana iri supercharging, kushandiswa kwenguva refu kunowanzo kudzikisa hupenyu hwebhatiri ne20% kusvika 30%. Naizvozvo, vagadziri vazhinji vanokurudzira kuwandisa senzira yekuchaja yekukurumidzira.
Vamwe vagadziri vanozounza overcharging pahwaro hwekuvandudza kutenderera hupenyu hwebhatiri pacharo. Kudzikiswa kwehupenyu hwebhatiri kunokonzerwa nekuwanda kwebhatiri kunodzikiswa nekuwedzera kwehupenyu hwebhatiri nemugadziri, izvo zvinozobvumira chigadzirwa chose kuchengetedza kuchaja kwakanaka uye kuburitsa kuita mukati menguva yazvinotarirwa yeupenyu.
Pamusoro pezvo, kuitira kuti uwane "flash charging", BYD yakaisawo nhevedzano yekuvandudza sisitimu yakatenderedza kukanganisa kwe lithium iron phosphate mabhatiri uye iyo yese magetsi system.
Kuti vatsivise kukanganisa kwekuita kwakadzikama tembiricha mumabhatiri e-lithium iron phosphate, sisitimu yeBYD ye "flash charging" inoburitsa mudziyo wekupisa wekupisa kuti uchengetedze nekukurumidza kuchaja uye kuburitsa kuita kwebhatiri kuburikidza nekuzvipisa wega munzvimbo dzinotonhora. Panguva imwecheteyo, kuitira kuti utsungirire kupisa kwebhatiri kunokonzerwa ne-high-power charger uye kubudisa, bhatiri rekamuri rinosanganiswa neine composite liquid cooling temperature control system, iyo inobvisa zvakananga kupisa kwebheteri kuburikidza nefiriji.
Panyaya yekuchengetedzwa kwekuita, lithium iron phosphate yakaratidza zvakare kukosha kwayo. Sekureva kweBYD, bhatiri re "flash charging" rakapfuura nyore 1200 ton kupwanya bvunzo uye 70km/h kudhumhana bvunzo. Iyo yakagadzikana kemikari chimiro uye murazvo unodzoreredza zvimiro zve lithium iron phosphate zvakare inopa yakanyanya kukosha vimbiso yekuchengetedza yemagetsi mota.
Kutarisana nebhodhoro rekuchaja
Zvichida vanhu vazhinji havana pfungwa yesimba remegawati, asi zvakakosha kunzwisisa kuti 1 megawatt inogona kunge iri simba refekitari yakakura-pakati, simba rakaiswa remagetsi ezuva diki, kana kushandiswa kwemagetsi munharaunda yevanhu chiuru.
Hongu, wazvinzwa zvakanaka. Simba rekuchaja remotokari rakaenzana nerefekitari kana nzvimbo inogara vanhu. Supercharging station yakaenzana nekushandiswa kwemagetsi kwehafu yemugwagwa. Uhu hukero hwekushandiswa kwemagetsi huchava dambudziko guru kune yazvino magetsi emudhorobha.
Hazvirevi kuti hapana mari yekuvaka zviteshi zvekuchaja, asi kuvaka zviteshi zvekuchaja zvakanyanya, zvinodikanwa kugadziridza iro guta rese uye gidhi remagetsi remugwagwa. Kungofanana nekugadzira dumplings zvakananga kune ndiro yevhiniga, chirongwa ichi chinoda kushanda nesimba. Nesimba rayo razvino, BYD yakaronga chete kuvakwa kwe4000 "megawatt flash kuchaja zviteshi" munyika yose mune ramangwana.
4000 'megawatt flash kuchaja zviteshi' hazvina kukwana. Flash kuchaja "mabhatiri uye" flash kuchaja "mota ingori nhanho yekutanga kusvika pakuwana" oiri nemagetsi nekumhanya kwakafanana ".
Nekubudirira mumotokari yemagetsi uye tekinoroji yebhatiri, dambudziko chairo rakatanga kuchinjika kukuvaka zvivako zvemagetsi uye magetsi emagetsi. Ose BYD neCATL, pamwe nemamwe makambani ebhatiri nemagetsi emotokari muChina, anogona kutarisana nemikana mikuru yemusika mune izvi.
