Nekukura kuri kuita musika wemagetsi emagetsi, mapombi ekuchaja emagetsi ...Mirwi yekuchaja yeDCvanokwanisa kupa simba reDC zvakananga kumabhatiri eEV, zvichideredza zvakanyanya nguva yekuchaja uye vanowanzo chaja kusvika 80 muzana mumaminitsi asingasviki 30. Nzira iyi yekuchaja inoshanda inoita kuti ishandiswe zvakanyanya kupfuuraMirwi yekuchaja yeACmunzvimbo dzakadai senzvimbo dzekuchaja dzeveruzhinji, nzvimbo dzekutengeserana nenzvimbo dzebasa remumigwagwa mikuru.
Panyaya yehunyanzvi, DC charging pile inonyanya kushandura simba remagetsi kuburikidza ne high-frequency switching power supply uye power module. Maumbirwo ayo emukati anosanganisira rectifier, filter uye control system kuti ive nechokwadi chekugadzikana uye kuchengetedzeka kwe output current. Panguva imwe chete, zvinhu zvine hungwaru zveMirwi yekuchaja yeDCzviri kuvandudzwa zvishoma nezvishoma, uye zvigadzirwa zvakawanda zvine nzira dzekutaurirana dzinogonesa kutaurirana kwedata panguva chaiyo nemagetsi emagetsi uye magridi emagetsi kuti zvivandudze maitiro ekuchaja uye manejimendi ekushandiswa kwesimba. Hunhu hwayo hwehunyanzvi hunosanganisira zvinhu zvinotevera:
1. Maitiro ekugadzirisa: Mapombi ekuchaja eDC ane ma rectifier akavakirwa mukati kuti akwanise kuchaja nekushandura simba reAC kuita simba reDC. Maitiro aya anosanganisira kushanda pamwe chete kwema diode akawanda kushandura hafu yevhiki yakanaka neisina kunaka yeAC kuita DC.
2. Kusefa uye Kudzora Voltage: Simba reDC rinoshandurwa rinogadziriswa nesefa kuti ribvise kushanduka kwemagetsi uye kuve nechokwadi chekuti magetsi anobuda akasimba. Pamusoro pezvo, muchina wekutonga voltage uchadzora voltage kuti uve nechokwadi chekuti voltage inogara iri mukati menzvimbo yakachengeteka panguva yekuchaja.
3. Sisitimu yekudzora ine hungwaru: Mapombi ekuchaja eDC emazuva ano ane sisitimu yekudzora ine hungwaru inotarisa mamiriro ekuchaja panguva chaiyo uye inogadzirisa simba rekuchaja nemagetsi kuti iwedzere kushanda zvakanaka kwekuchaja uye idzivirire bhatiri zvakanyanya.
4. Maitiro ekutaurirana: Kutaurirana pakati pemachaja eDC nemaEV kunowanzo enderana nemitemo yakajairika yakaita seIEC 61850 neISO 15118, iyo inobvumira kuchinjana ruzivo pakati pechaja nemotokari, zvichiita kuti maitiro ekuchaja ave akachengeteka uye anoshanda.
Nezvemitemo yekuchaja mushure mezvigadzirwa, DC charging post post product post inotevedzera mitemo yepasi rose neyenyika kuti ive nechokwadi chekuti yakachengeteka uye inoenderana. Iyo IEC 61851 standard yakapihwa neInternational Electrotechnical Commission (IEC) inopa gwara pamusoro pekubatana pakati peEVs nenzvimbo dzekuchaja, ichifukidza nzvimbo dzemagetsi uye maprotocol ekutaurirana. YeChinaGB/T 20234 standard, kune rumwe rutivi, inotsanangura zvinodiwa zvehunyanzvi uye zvirevo zvekuchengetedza pamapombi ekuchaja. Mitemo iyi yese inodzora mwero weindasitiri yekugadzira nekudhizaina mapombi ekuchaja kusvika pamwero wakati, uye kusvika pamwero wakati, inobatsira kusimudzira budiriro yakanaka yemusika wemotokari itsva dzemagetsi neindasitiri dzinovatsigira.
Kana tichitarisa rudzi rwepfuti dzekuchaja dzemurwi wekuchaja weDC, murwi wekuchaja weDC unogona kukamurwa kuita murwi wekuchaja wepfuti imwe chete, pfuti mbiri uye pfuti dzakawanda. Murwi wekuchaja wepfuti imwe chete wakakodzera nzvimbo diki dzekuchaja, nepo murwi wekuchaja wepfuti mbiri nepfuti dzakawanda wakakodzera nzvimbo hombe kuti dzisvike pakudiwa kwakanyanya kwekuchaja. Nzvimbo dzekuchaja dzepfuti dzakawanda dzakakurumbira nekuti dzinogona kushandira maEV akawanda panguva imwe chete, zvichiwedzera kushanda zvakanaka kwekuchaja.
Pakupedzisira, pane tarisiro yemusika wezvimedu zvekuchaja: ramangwana rezvimedu zvekuchaja zveDC richazara neruzivo sezvo tekinoroji ichifambira mberi uye kudiwa kwemusika kuchikura. Kusanganiswa kwemagrid akangwara, mota dzisina kutyaira uye simba rinodzokororwa kuchaunza mikana mitsva isingaenzaniswi yezvimedu zvekuchaja zveDC. Kuburikidza nekufambira mberi kwenguva yegreen era, tinotenda kuti zvimedu zvekuchaja zveDC hazvizongopi vashandisi ruzivo rwakanyanya nyore rwekuchaja, asi zvichabatsirawo mukuvandudzwa kwakasimba kwenzvimbo yese ye e-mobility.
Kana uchida kuziva zvakawanda nezvekupa mazano pachiteshi chekuchaja, unogona kudzvanya pa:Ita kuti unzwisise zvakadzama nezvezvigadzirwa zvitsva zviri kufarirwa - murwi wekuchaja weAC
