Nhanganyaya：
Kuchaja kwemaminitsi mashanu nemakiromita mazana mana! Musi wa17 Kurume, BYD yakaburitsa sisitimu yayo ye "megawatt flash charging", iyo ichaita kuti mota dzemagetsi dzikwanise kuchaja nekukurumidza sekunge dziri kuwedzera mafuta.
Zvisinei, kuti ikwanise kuzadzisa chinangwa che "oiri nemagetsi nekumhanya kumwe chete", BYD inoita kunge yasvika pamuganho webhatiri rayo re lithium iron phosphate. Kunyangwe hazvo huwandu hwesimba rezvinhu zve lithium iron phosphate pachazvo huri kusvika pamuganho waro wedzidziso, BYD ichiri kusundira dhizaini yechigadzirwa uye kugadzirisa tekinoroji zvakanyanya.
Tamba zvakanyanya! 10C lithium iron phosphate
Chekutanga, zvichienderana neruzivo rwakaburitswa pamusangano wevatori venhau weBYD, tekinoroji yekuchaja yeBYD inoshandisa chigadzirwa chinonzi "flash charging blade battery", icho chichiri rudzi rwe lithium iron phosphate battery.
Izvi hazvingogumiri pakuderedza simba remabhatiri e lithium ane mutengo wakakwira senge mabhatiri ane nickel ternary akawanda mumusika wekuchaja nekukurumidza, asi zvinobvumirawo BYD kusundidzira mashandiro e lithium iron phosphate zvakanyanya zvakare, zvichibvumira BYD kuramba ichikosha pamusika munzira yetekinoroji yemabhatiri e lithium iron phosphate.
Zvichienderana nedata rakaburitswa neBYD, BYD yasvika padanho repamusoro rekuchaja re1 megawatt (1000 kW) kune mamwe mamodheru akadai seHan L neTang L, uye kuchaja kweflash kwemaminetsi mashanu kunogona kuwedzera makiromita mazana mana enzvimbo. Bhatiri rayo rekuchaja kweflash rasvika padanho rekuchaja re10C.
Pfungwa iyi ndeipi? Panyaya yesainzi, parizvino zvinozivikanwa muindasitiri kuti huwandu hwesimba remabhatiri e lithium iron phosphate huri pedyo nemuganhu wedzidziso. Kazhinji, kuti vave nechokwadi chekuti huwandu hwesimba hwakakwira, vagadziri vanorega zvimwe zvekushanda kwavo kwekuchaja nekuburitsa. Kazhinji, kuburitsa 3-5C kunoonekwa sehuwandu hwakakodzera hwekuburitsa mabhatiri e lithium iron phosphate.
Zvisinei, panguva ino BYD yakawedzera mwero wekuburitswa kwe lithium iron phosphate kusvika ku10C, izvo hazvireve chete kuti magetsi awedzera kaviri, asi zvinorevawo kuti kuramba kwemukati uye kuoma kwekutonga kupisa zvawedzera kaviri.
BYD inoti zvichibva pabanga, "bhatiri rekuchaja reFlash" raBYD rinogadzirisa chimiro cheelectrode chebhatiri rebanga, richideredza kuramba kweioni dze lithium ne50%, zvichiita kuti pave nekuchaja kweanopfuura 10C kekutanga.
Pazvinhu zvakanaka zve electrode, BYD inoshandisa zvinhu zve lithium iron phosphate zvine kuchena kwakanyanya, kumanikidzwa kwakanyanya, uye density yakakura yechizvarwa chechina, pamwe chete ne nanoscale crushing processes, special formula additives, uye high-temperature calcination processes. Chimiro chemukati chekristaro chakakwana uye nzira pfupi yekupararira kwe lithium ions inowedzera huwandu hwekufamba kwema lithium ions, nokudaro ichideredza kuramba kwemukati mebhatiri uye inovandudza mashandiro ekuburitsa.
Pamusoro pezvo, maererano nekusarudza maelectrode asina kunaka uye maelectrolyte, zvakakoshawo kusarudza akanakisa kubva pane akanakisa. Kushandiswa kwegraphite yekugadzira ine nzvimbo yepamusoro uye kuwedzerwa maelectrolyte ePEO (polyethylene oxide) anoshanda zvakanyanya kwavewo mamiriro anodiwa ekutsigira mabhatiri e10C lithium iron phosphate.
Muchidimbu, kuti ibudirire pakuita basa rayo, BYD haina mari yakawanda. Pamusangano wevatori venhau, mutengo weBYD Han L EV ine bhatiri re "flash charging" wasvika pa270000-350000 yuan, inova yakakwira ne70000 yuan kupfuura mutengo we2025 EV intelligent driving version (701KM Honor model).
Ndeipi nguva yehupenyu uye kuchengetedzeka kwemabhatiri ekuchaja flash?
Ehe, kune vane tekinoroji yepamusoro, kudhura hakusi dambudziko. Munhu wese achiri kunetseka nezvemhando uye kuchengetedzeka kwechigadzirwa. Nezve izvi, Lian Yubo, Executive Vice President weBYD Group, akataura kuti mabhatiri ekuchaja flash anogona kuramba achishanda kwenguva refu kunyangwe akachajwa zvakanyanya, nekuwedzera kwe35% muhupenyu hwebhatiri.
Zvinogona kutaurwa kuti mhinduro yaBYD panguva ino yakarurama uye izere nehunyanzvi, zvirinani kusaramba kuti kuchaja zvakanyanya kunokanganisa hupenyu hwebhatiri.
Nekuti pachokwadi, kuchaja nekukurumidza nekuburitsa bhatiri zvichave nemigumisiro isingachinjiki pachimiro charo. Kana bhatiri rikakurumidza kuchaja nekuburitsa bhatiri, ndipo pachanyanya kukanganisa hupenyu hwebhatiri. Kana iri supercharging, kushandiswa kwenguva refu kunowanzo deredza hupenyu hwebhatiri ne20% kusvika 30%. Saka, vagadziri vazhinji vanokurudzira kubhadharisa zvakanyanya senzira yekuchaja nekukurumidza.
Vamwe vagadziri vanoisa mari yakawanda vachifunga nezvekuvandudza hupenyu hwebhatiri pacharo. Kudzikira kwehupenyu hwebhatiri kunokonzerwa nekuchaja zvakanyanya kunodzikiswa nekuwedzera kwehupenyu hwebhatiri nemugadziri, zvichizobvumira chigadzirwa chose kuchengetedza kushanda zvakanaka kwekuchaja uye kuburitsa mari mukati mehupenyu hwacho hunotarisirwa.
Pamusoro pezvo, kuti vawane "flash charging", BYD yakaisawo nhevedzano yekuvandudza sisitimu maererano nekushaikwa kwemabhatiri e lithium iron phosphate uye sisitimu yese yemagetsi.
Kuti itsive zvikanganiso zvekushanda kwekupisa kwakaderera mumabhatiri e lithium iron phosphate, sisitimu yeBYD ye "flash charging" inounza mudziyo wekupisa wepulse kuti uchengetedze kushanda kwekuchaja nekuburitsa bhatiri nekukurumidza kuburikidza nekudziyisa wega munzvimbo dzinotonhora. Panguva imwe chete, kuitira kuti ikwanise kugadzirisa kupisa kwebhatiri kunokonzerwa nekuchaja nekuburitsa bhatiri nesimba rakawanda, kamuri rebhatiri rakabatanidzwa nesystem yekudzora tembiricha inotonhorera yemvura, iyo inobvisa zvakananga kupisa kwebhatiri kuburikidza nerefrigerant.
Panyaya yekushanda zvakanaka, lithium iron phosphate yaratidza kukosha kwayo zvakare. Sekureva kweBYD, bhatiri rayo re "flash charging" rakapasa bvunzo yekupwanya ye1200 ton uye bvunzo yekurovera ye70km/h. Maumbirwo akasimba emakemikari uye hunhu hwe lithium iron phosphate hunodzora moto zvakare zvinopa vimbiso huru yekuchengetedza mota dzemagetsi.
Kutarisana nedambudziko rekuchaja
Pamwe vanhu vazhinji havana pfungwa yesimba re megawatt, asi zvakakosha kunzwisisa kuti 1 megawatt inogona kunge iri simba refekitori yepakati nepakati, simba rakaiswa renzvimbo diki yesimba rezuva, kana kushandiswa kwemagetsi munharaunda yevanhu chiuru.
Ehe, wazvinzwa zvakanaka. Simba rekuchaja remota rakaenzana nerefekitori kana nzvimbo yekugara. Nzvimbo yekuchaja magetsi yakaenzana nekushandiswa kwemagetsi kwehafu yemugwagwa. Kushandiswa kwemagetsi uku kuchave dambudziko guru kune grid yemagetsi yemaguta iripo.
Hazvirevi kuti hapana mari yekuvaka nzvimbo dzekuchaja, asi kuti uvake nzvimbo dzekuchaja zvakanyanya, zvakakosha kugadzirisa grid yemagetsi muguta rese nemumugwagwa. Kungofanana nekugadzira madumplings edhishi revhiniga, chirongwa ichi chinoda kushanda nesimba. Nesimba rayo pari zvino, BYD yakaronga kuvaka nzvimbo dzinopfuura 4000 dze "megawatt flash charging" munyika yese mune ramangwana.
'Mafurati ekuchaja mamegawatt' 4000 haana kukwana. "Mabhatiri ne" mota dzekuchaja maflash ingori nhanho yekutanga yekuwana "mafuta nemagetsi nekumhanya kwakafanana".
Nekufambira mberi kuri kuita tekinoroji yemotokari dzemagetsi nemabhatiri, dambudziko guru rakatanga kuchinjirwa kukuvakwa kwenzvimbo dzemagetsi nemanetiweki emagetsi. BYD neCATL, pamwe nemamwe makambani emabhatiri nemotokari dzemagetsi muChina, vanogona kusangana nemikana yakakura yemusika panyaya iyi.
