-Kana iwe uchida kukurumidza kuchaja mota yako yemagetsi, haugone kukanganisa neakakwira-voltage, yakakwira-yazvino tekinoroji yekuchaja mapundu.

High current uye high voltage technology

Sezvo huwandu hunowedzera zvishoma nezvishoma, kune matambudziko akadai sekupfupisa nguva yekuchaja uye kuderedza mutengo wevaridzi, uye basa rekutanga nderekukwidziridza saizi yemodule kuti uwane kukwidziridzwa kwemagetsi. Sezvo simba rekuchaja murwizvakanyanya zvinoenderana nepamusoro pesimba reiyo module yekuchaja, uye inoganhurwa nehuwandu hwechigadzirwa, nzvimbo yepasi uye mutengo wekugadzira, kungowedzera huwandu hwemamodule haisisiri mhinduro yakanaka. Naizvozvo, maitiro ekuwedzera simba reimwe module pasina kuwedzera vhoriyamu rave dambudziko rehunyanzvi irokuchaja module vagadzirizvinoda kukunda nokukurumidza.

DC yekuchaja michinainowana yakanakisa yekuchaja yekuchaja kuburikidza nepamusoro-ikozvino uye yakakwirira-voltage tekinoroji. Nekuwedzera zvishoma nezvishoma kwemagetsi uye simba, izvi zvinoisa mberi zvakanyanya kuomesesa zvinodiwa zvekushanda kwakagadzikana, kunyatsopisa kupisa uye kutendeutsa kunyatsoshanda kwechaji module, iyo pasina mubvunzo inogadzirisa matambudziko epamusoro ekuchaja vanogadzira module.

Pamberi pekuda kwemusika wepamusoro-simba nekukurumidza kuchaja, kuchaja module vagadziri vanofanirwa kuenderera mberi nekuvandudza nekusimudzira tekinoroji yepasi uye kuvaka yavo yepakati tekinoroji zvipingamupinyi. Ichi chichava kiyi yekukwikwidza kwemusika mune ramangwana, chete nekugona iyo yakakosha tekinoroji, kuitira kuti isakundike mumakwikwi anotyisa emusika.

1) Nzira yepamusoro-yazvino: dhigirii yekusimudzira yakaderera, uye zvinodikanwa zvekutonga kwekupisa zvakakwirira. Maererano nemutemo waJoule (formula Q = I2Rt), kuwedzera kwezvino kuchawedzera zvakanyanya kupisa panguva yekuchaja, iyo ine zvinodiwa zvakanyanya zvekupisa kupisa, senge Tesla's high-current fast charger solution, iyo V3 supercharging pile ine peak yekushanda ikozvino inopfuura 600A, inoda iyo gobvu wiring harness, uye panguva imwechete yekupisa inogona kuzadzisa tekinoroji. simba rekuchaja rinosvika 250kW mu5% -27% SOC, uye kuchaja kwakanaka hakuna kuvharwa zvizere. Parizvino, vagadziri vemotokari dzepamba havana kuita shanduko dzakakosha dzakagadziriswa muchirongwa chekupisa kupisa, uyehigh-current kuchaja mirwivimba zvakanyanya pazvirongwa zvekuzvivaka, zvichikonzera mutengo wekusimudzira.

2) High-voltage nzira: Imodhi inowanzoshandiswa nevagadziri vemotokari, iyo inogona kufunga nezvezvakanakira kuderedza kushandiswa kwesimba, kuvandudza hupenyu hwebhatiri, kuderedza uremu, uye kuchengetedza nzvimbo. Parizvino, yakaganhurirwa neainstand voltage capacity yesilicon-based IGBT magetsi emagetsi, mhinduro yekuchaja yekukurumidza inowanzogamuchirwa nemakambani emotokari i400V yakakwira-voltage chikuva, kureva kuti, simba rekuchaja re100kW rinogona kuwanikwa neiyo 250A (100kW simba rinogona kuchajwa kwe10km kweinenge gumi). Kubva pakaparurwa yePorsche's 800V high-voltage platform (kuwana 300KW simba uye nepakati nepakati-high-voltage wiring harness), makambani makuru emotokari atanga kutsvagisa nekugadzirisa 800V high-voltage platform. Kuenzaniswa ne400V papuratifomu, iyo 800V voltage chikuva ine diki inoshanda ikozvino, iyo inochengetedza vhoriyamu yewaya tambo, inoderedza kurasika kwemukati kwekupokana kwedunhu, uye inovandudza kusimba kwesimba uye kugona kwesimba mukuvanza.

Parizvino, simba rinogara richibuda remagetsi emhando huru ye40kW module muindasitiri ndeye 300Vdc ~ 1000Vdc, inowirirana nezvinodiwa zvekuchaja zvezvino 400V papuratifomu motokari dzinotakura vanhu, 750V mabhazi uye ramangwana 800V-1000V high-voltage platform motokari; Iyo yakabuda voltage range ye40kW module yeInfineon, Telai neShenghong inogona kusvika 50Vdc ~ 1000Vdc, tichifunga nezvekuchaja zvinodiwa zvemotokari dzakaderera-voltage. Panyaya yekushanda kwese kwese module, iyo 40kW yakakwirira-inoshanda modules yeBeiHai Powershandisa SIC masimba emagetsi, uye kugona kwepamusoro kunogona kusvika 97%, iyo yakakwira kupfuura avhareji yeindasitiri.
