Range kufunganya ndiro bhodhoro hombe rinodzikamisa budiriro yemusika wemotokari yemagetsi, uye zvinoreva kuseri kwekunyatso ongorora kushushikana kwemhando "kutsungirira kwenguva pfupi" uye "kunonoka kuchaja". Parizvino, mukuwedzera kuhupenyu hwebhatiri, zvakaoma kufambira mberi, saka "kukurumidza kuchaja" uye "supercharge" ndiyo inotariswa yekurongeka kwazvino kwemakambani emotokari akasiyana. Saka iyo800V high voltagechikuva chakavapo.
Kune vatengiwo zvavo, iyo 800V yakakwira-voltage chikuva inosimudzirwa nemakambani emotokari ingori tekinoroji, asi sehunyanzvi hwakakosha mune ramangwana, zvakare ine chekuita neruzivo rwemotokari yemutengi, uye isu tinofanirwa kuve nekunzwisisa kwakazara kweiyi tekinoroji nyowani. . Nokudaro, bepa rino richaita ongororo yakadzama ye800V yakakwirira-yekumanikidza papuratifomu kubva kune zvakasiyana-siyana semusimboti, kudiwa, kusimudzira uye kumhara.
Sei uchida 800V chikuva?
Mumakore maviri apfuura, nekuwedzera zvishoma nezvishoma muhuwandu hwemotokari dzemagetsi, nhamba yekutakura mirwi yakakwira panguva imwe chete, asi chiyero chemurwi hachina kuderera. Pakupera kwa2020, "car-pile ratio" yemotokari nyowani dzemagetsi i2.9: 1 (nhamba yemotokari i4.92 miriyoni uye nhamba yekuchaja mirwi i1.681 miriyoni). Muna 2021, chiyero chemotokari kumurwi chichava 3: 1, iyo isingazodzike asi kuwedzera. Mhedzisiro ndeyokuti nguva yemutsara yakareba kudarika nguva yekuchaja.
Zvino kana iri iyo nhamba yekuchaja mirwi haigone kuramba ichikwira, kuitira kuti uderedze nguva yebasa yekuchaja mirwi, kukurumidza kuchaja tekinoroji yakakosha.
Kuwedzera kwekumhanya kwekuchaja kunogona kungonzwisiswa sekuwedzera kwesimba rekuchaja, ndiko kuti, P = U·I muP (P: simba rekuchaja, U: vhezheni yekuchaja, I: kuchaja ikozvino). Naizvozvo, kana iwe uchida kuwedzera simba rekuchaja, chengeta imwe yemagetsi kana ikozvino isina kuchinjika, kuwedzera voltage kana ikozvino kunogona kuvandudza simba rekuchaja. Kuunzwa kweyakakwira voltage papuratifomu ndeye kuvandudza kugona kuchaja kwekupedzisira kwemotokari uye kuona kukurumidza kudzoreredza kwekupedzisira kwemotokari.
Iyo 800V papuratifomukumotokari dzemagetsi ndiyo sarudzo huru yekuchaja nekukurumidza. Kune mabhatiri emagetsi, kukurumidza kuchaja kunonyanya kuwedzera kuchaja ikozvino kwesero, inozivikanwawo seyero yekuchaja; Parizvino, makambani emotokari mazhinji ari muchimiro chemakiromita e1000 ekutyaira, asi tekinoroji yebhatiri iripo, kunyangwe yakagadziridzwa kuita mabhatiri akasimba, inodawo bhatiri remagetsi rinopfuura 100kWh, izvo zvinotungamira kuwedzera kwehuwandu hwemasero, kana iyo huru ye400V platform inoramba ichishandiswa, nhamba yemasero akaenzana inowedzera, zvichiita kuti kuwedzera kwebhazi ikozvino. Iyo inounza dambudziko rakakura kune copper waya yakatarwa uye kupisa pombi chubhu.
Naizvozvo, zvinodikanwa kushandura akateedzana parallel chimiro chebhatiri masero mubhatiri pack, kuderedza kufanana uye kuwedzera nhevedzano, kuitira kuti uwedzere kuchaja ikozvino uchichengetedza chikuva chazvino mune inonzwisisika nhanho renji. Nekudaro, sezvo huwandu hweakateedzera hunowedzera, bhatiri pack yekupedzisira voltage inowedzerwa. Iyo voltage inodiwa kuti 100kWh bhatiri paki iwane 4C nekukurumidza kuchaja ingangoita 800V. Kuti ienderane neanokurumidza kuchaja basa remazinga ese emamodheru, 800V magetsi ekuvaka ndiyo yakanakisa sarudzo.
