–Kana uchida kuchaja mota yako yemagetsi nekukurumidza, haugone kukanganisa netekinoroji yemagetsi ane simba guru uye ane simba guru rekuchaja mapombi.

Tekinoroji yemagetsi yakakwira uye yakakwira

Sezvo huwandu hwacho huchikwira zvishoma nezvishoma, kune matambudziko akadai sekupfupisa nguva yekuchaja uye kuderedza mutengo wekuva muridzi, uye basa rekutanga nderekugadzirisa saizi yemodule kuti uwane kuvandudzwa kwesimba. Sezvo simba remurwi wekuchajaZvinonyanya kuenderana nehukuru hwesimba remodule yekuchaja, uye zvinogumira pahuwandu hwechigadzirwa, nzvimbo yepasi uye mutengo wekugadzira, kungowedzera huwandu hwemamodules hakusisiri mhinduro yakanakisisa. Saka, nzira yekuwedzera simba remodule imwe chete pasina kuwedzera vhoriyamu yave dambudziko rehunyanzvi irovagadziri vemodule yekuchajakudiwa kwekukunda nekukurumidza.

Midziyo yekuchaja yeDCinowana kugona kukuru kwekuchaja nekukurumidza kuburikidza netekinoroji yemagetsi ane simba rakawanda uye ane simba rakawanda. Nekuwedzera zvishoma nezvishoma kwemagetsi nesimba, izvi zvinopa zvinodiwa zvakasimba zvekushanda kwakasimba, kudzima kupisa zvakanaka uye kushanda zvakanaka kwemodule yekuchaja, izvo pasina mubvunzo zvinoisa matambudziko makuru ehunyanzvi kune vagadziri vemodule yekuchaja.

Pamusana pekudiwa kwemusika kwekuchaja nekukurumidza nesimba guru, vagadziri vemamodule ekuchaja vanofanirwa kuramba vachigadzira nekuvandudza tekinoroji iri pasi uye kuvaka zvipingamupinyi zvavo zvehunyanzvi. Izvi zvichave kiyi yemakwikwi emusika emangwana, chete nekuziva tekinoroji huru, kuti vasakundike mumakwikwi emusika akasimba.

1) Nzira yemagetsi ane simba guru: mwero wekukwidziridzwa wakaderera, uye zvinodiwa zvekutarisira kupisa zvakanyanya. Zvinoenderana nemutemo waJoule (formula Q=I2Rt), kuwedzera kwemagetsi kuchawedzera kupisa zvakanyanya panguva yekuchaja, izvo zvine zvinodiwa zvakanyanya zvekuparadza kupisa, zvakaita seTesla's high-current fast charging solution, ine V3 supercharging pile ine peak working current inodarika 600A, inoda waya yakakora, uye panguva imwe chete, ine zvinodiwa zvakanyanya zvetekinoroji yekubvisa kupisa, uye inogona chete kuwana simba rekuchaja re250kW mu5%-27% SOC, uye kuchaja kwakanaka hakuna kuvharwa zvizere. Parizvino, vagadziri vemotokari dzemumba havana kuita shanduko dzakakura dzakagadziriswa muchirongwa chekuparadza kupisa, uyemirwi yekuchaja ine simba gurukuvimba zvakanyanya nemasisitimu anozvigadzirira ega, zvichikonzera mitengo yakakwira yekukwidziridza.

2) Nzira yemagetsi ane simba guru: Inzira inowanzoshandiswa nevagadziri vemotokari, iyo inogona kufunga nezvezvakanakira zvekuderedza kushandiswa kwesimba, kuvandudza hupenyu hwebhatiri, kuderedza huremu, uye kuchengetedza nzvimbo. Parizvino, inoganhurirwa nekukwanisa kwemagetsi esimbi yeIGBT ine silicon-based power devices, mhinduro yekuchaja nekukurumidza inowanzo shandiswa nemakambani emotokari ipuratifomu ine simba re400V, kureva kuti, simba rekuchaja re100kW rinogona kuwanikwa nemagetsi e250A (simba re100kW rinogona kuchajwa kwemaminitsi gumi kweinenge 100km). Kubva pakatangwa puratifomu ine simba rePorsche ye800V (ichiwana simba re300KW uye ichideredza nehafu yemagetsi ane simba remagetsi ane simba guru), makambani makuru emotokari akatanga kutsvaga nekugadzira puratifomu ine simba re800V. Zvichienzaniswa nepuratifomu ye400V, puratifomu ine simba re800V ine simba rekushanda diki, rinochengetedza huwandu hwemagetsi ane simba, rinoderedza kurasikirwa kwemukati kwedunhu, uye rinovandudza huwandu hwesimba uye kushanda zvakanaka kwesimba rakavanzwa.

Parizvino, simba rinobuda nguva dzose remagetsi e40kW module iri muindasitiri iyi i300Vdc ~ 1000Vdc, izvo zvinoenderana nezvinodiwa zvekuchaja zvemotokari dze400V dziripo papuratifomu, mabhazi e750V uye mota dze800V-1000V dzepamusoro-soro dzemunguva yemberi; Voltage inobuda ye40kW module yeInfineon, Telai neShenghong inogona kusvika 50Vdc ~ 1000Vdc, tichifunga nezvezvinodiwa zvekuchaja zvemotokari dzine voltage shoma. Panyaya yekushanda zvakanaka kwemodule, mamodule e40kW ane simba guru remagetsi e ...BeiHai Powershandisai michina yemagetsi yeSIC, uye kushanda zvakanaka kunogona kusvika 97%, iyo iri pamusoro peavhareji yeindasitiri.
