Nekukurumidza kukura kwemusika weEV, DC yekuchaja mirwi yave chikamu chakakosha cheEV yekuchaja zvivakwa nekuda kwehunhu hwavo, uye kukosha kweDC yekuchaja zviteshi zvave kuwedzera mukurumbira. Kuenzaniswa ne AC kuchaja mapairi,DC kuchaja mirwivanokwanisa kupa DC simba rakananga kumabhatiri eEV, vachideredza zvakanyanya nguva yekuchaja uye kazhinji vachichaja kusvika makumi masere muzana mumaminetsi asingasviki makumi matatu. Iyi nzira yekuchaja inoshanda inoita kuti ishandiswe zvakanyanya kupfuuraAC kuchaja mirwimunzvimbo dzakaita sezviteshi zvekuchaja veruzhinji, nzvimbo dzekutengesa nenzvimbo dzemasevhisi emigwagwa.
Panyaya yetekinoroji musimboti, DC yekuchaja murwi inonyanya kuona shanduko yesimba remagetsi kuburikidza nepamusoro-frequency switching power supply uye power module. Chimiro chayo chemukati chinosanganisira rectifier, sefa uye control system kuti ive nechokwadi chekugadzikana uye kuchengetedzeka kwekubuda kwazvino. Zvichakadaro, zvinhu zvakangwara zveDC kuchaja mirwiinovandudzwa zvishoma nezvishoma, uye zvigadzirwa zvakawanda zvakashongedzerwa nemafambisirwo ekutaurirana anogonesa-chaiyo-nguva data kudyidzana neEVs uye magidhi emagetsi kukwenenzvera nzira yekuchaja uye kutonga kwesimba rekushandisa. Yayo tekinoroji musimboti mbiri inonyanya kusanganisira zvinotevera zvinhu:
1. Kugadzirisa maitiro: DC yekuchaja mirwi ine akavakirwa-mukati rectifiers kuti awane kuchaja nekushandura AC simba kuita DC simba. Kuita uku kunosanganisira basa rekubatana remadhiodhi akawanda kushandura yakanaka uye yakaipa hafu yevhiki dzeAC kuita DC.
2. Kusefa uye Voltage Regulation: Iyo yakashandurwa DC simba inokwenenzverwa nesefa kuti ibvise kushanduka kwezvino uye kuve nechokwadi kugadzikana kwekubuda kwezvino. Uye zvakare, iyo voltage regulator inodzora iyo voltage kuti ive nechokwadi chekuti voltage inogara iri mukati meiyo yakachengeteka renji panguva yekuchaja.
3. Intelligent control system: Yemazuva ano DC yekuchaja mirwi yakashongedzerwa nehungwaru kudzora sisitimu inotarisisa mamiriro ekuchaja munguva chaiyo uye inogadzirisa zvine simba kuchaja ikozvino uye voltage kuti iwedzere kuchaja kunyatsoshanda uye kudzivirira bhatiri kusvika pamwero mukuru.
4. Mitemo yekukurukurirana: Kukurukurirana pakati pemachaja eDC neEVs kunowanzoenderana nemaitiro akamisikidzwa akadai seIEC 61850 uye ISO 15118, ayo anobvumira kupanana ruzivo pakati pechaja nemotokari, kuve nechokwadi chekuchengetedza uye kugona kwemaitiro ekuchaja.
Nezvekuchajisa post product standards, DC yekuchaja posts inoteedzera akati wandei epasi rese uye emunyika mwero kuti ive nechokwadi chekuchengetedza uye kuenderana. Iyo IEC 61851 chiyero chakapihwa neInternational Electrotechnical Commission (IEC) inopa nhungamiro pakubatana pakati peEVs nezvivakwa zvekuchaja, inovhara magetsi ekubatanidza uye maprotocol ekutaurirana. China'sGB/T 20234 yakajairwa, kune rumwe rutivi, inodonongodza iyo tekinoroji zvinodiwa uye chengetedzo yakatarwa yekuchaja mirwi. Ese aya mazinga anotonga zviyero zvekuchaja murwi kugadzira uye dhizaini indasitiri kusvika pamwero wakati, uye kusvika pamwero wakati, anobatsira kusimudzira hutano hwemusika wemotokari dzemagetsi emagetsi matsva uye maindasitiri anotsigira.
Panyaya yemhando yekuchaja pfuti yeDC yekuchaja murwi, DC yekuchaja murwi inogona kukamurwa kuita imwechete-pfuti, mbiri-pfuti uye yakawanda-pfuti yekuchaja murwi. Mirwi yekuchaja pfuti imwe chete inokodzera zviteshi zvidiki zvekuchaja, nepo mbiri-pfuti uye dzakawanda-pfuti dzekuchaja mirwi dzakakodzera nzvimbo hombe kusangana nepamusoro pekuchaja kudiwa. Mazhinji-pfuti ekuchaja mapositi anonyanya kufarirwa nekuti anogona kushandira akawanda maEV panguva imwe chete, achiwedzera zvakanyanya kuchaja kugona.
Chekupedzisira, kune tarisiro yemusika wekuchaja mirwi: ramangwana reDC yekuchaja mapairi rine chokwadi chekuti richazara nekugona sezvo tekinoroji inofambira mberi uye kudiwa kwemusika kuchikura. Iko kusanganiswa kwemagridhi akangwara, mota dzisingatyairi uye simba rinodzokororwa zvinounza mikana mitsva isati yamboonekwa yeDC yekuchaja mapile. Kuburikidza nekumwe kusimudzira kweyakasvibira nguva, isu tinotenda kuti DC yekuchaja mirwi haingope vashandisi ruzivo rwakanyanya kubhadharisa, asi inozopedzisira yabatsira mukusimudzira kwakasimba kwese e-mobility ecosystem.
Kana iwe uchida kuziva zvakawanda nezve kuchaja chiteshi chekubvunza, unogona kudzvanya pa:Tora iwe nzwisiso yakadzama yezvinyowani zvigadzirwa - AC yekuchaja murwi
