Kuyedzwa kwekudzivirira pasi kwemapombi ekuchaja eAC/DC emotokari itsva dzemagetsi

1. Kudzivirira pasi pemapombi ekuchaja

Nzvimbo dzekuchaja dzemagetsi dzakakamurwa kuita mhando mbiri:Mirwi yekuchaja yeACuye mirwi yekuchaja yeDC. Mirwi yekuchaja yeAC inopa simba re220V AC, iro rinoshandurwa kuita simba reDC rine voltage yepamusoro nechaja iri mubhodhi kuti ichajise bhatiri remagetsi.Mirwi yekuchaja yeDCinopa simba re380V remagetsi matatu, iro rinochaja bhatiri zvakananga kuburikidza nechiteshi chekuchaja nekukurumidza pasina kupfuura nepachaja iri mubhazi. Standard yenyika GB/T20234.1 inotsanangura zvakajeka zvinodiwa zvemota uye mashandisirwo emagetsi.Macharger eAC EVshandisa interface yenyika ine mapini manomwe, ukuwoMachaja eDCshandisai national standard nine-pin interface. Ma PE pin ema charging interfaces maviri ari padivi pemota ese ari maviri grounding terminals (ona Mufananidzo 1). Basa reground wire PE nderekugaya muviri wemota yemagetsi kuburikidza neACnzvimbo yekuchaja mota yemagetsi. Mumutemo wenyika weGB/T 18487.1, waya yepasi pevhu yemuchina wemagetsi inofanira kubatanidzwa nepasi pemotokari yemagetsi (PE pin iri paMufananidzo 1) kuti nzira yekuchaja yemotokari yemagetsi ishande zvakanaka.

Mufananidzo 1. PE Pin yeMotokari-Kurutivi rwekuchaja Interface

Kutora nzira yekuchaja apo ACnzvimbo yekuchaja mota yemagetsiinoshandisa chinobatanidza mota chine plug mbiri kuti ibatanidze kunenzvimbo yekuchaja mota yemagetsisemuenzaniso, dunhu rekudzora rehurongwa hwekuchaja uhwu rinoongororwa, uye dhayagiramu yaro yedunhu inoratidzwa muMufananidzo 2.

Kana michina yemagetsi yaiswa kuti ichajike, kana michina yacho isina zvikanganiso, voltage iri panzvimbo yekutanga inofanira kunge iri 12V.

Kana mushandi akabata pfuti yekuchaja odzvanya kiyi yemuchina, S3 inovhara, asi chiratidziro chemotokari hachina kubatana zvizere, voltage iri panzvimbo yekutanga yekuona i9V.

Kanapfuti yekuchajaYakabatana zvizere nechiteshi chekuchaja chemotokari, S2 inovhara. Panguva ino, voltage iri panzvimbo yekuona 1 inodonha nekukurumidza. Muchina wemagetsi unosimbisa chiratidzo kuburikidza neCC connection uye unoona magetsi anogona kumiriswa netambo yekuchaja, uchichinja switch S1 kubva kumagumo e12V kuenda kumagumo ePWM.

Kana voltage iri panzvimbo yekuona 1 yadzikira kusvika pa6V, inochinja K1 neK2 yemuchina wemagetsi iri pedyo ne output current, nokudaro ichipedzisa power supply circuit. Mushure mekunge mota yemagetsi nemidziyo yemagetsi zvabatana, mudziyo wekudzora mota unosarudza simba repamusoro remuchina wemagetsi nekutarisa duty cycle yePWM signal panzvimbo yekuona 2. Semuenzaniso, kune 16A charging pile, duty cycle i73.4%, saka voltage iri paCP end inochinja-chinja pakati pe6V ne -12V, nepo voltage iri paCC end… terminal voltage inodonha kubva pa4.9V (connected state) kuenda ku1.4V (charging state).

Kana chikamu chekudzora mota chaona kuti chinongedzo chekuchaja chakabatana zvizere (kureva kuti, S3 neS2 zvakavharwa) uye zvapedzisa kugadzika kwemagetsi ekupinda anotenderwa echarger ari mubhodhi (S1 inochinja kuenda kuPWM terminal, K1 neK2 zvakavharwa), charger iri mubhodhi inotanga kuchaja mota yemagetsi.

Munguva iyi, kana waya yePE ground ikabviswa, hapana shanduko yemagetsi ichaitika panzvimbo yekuona, dunhu remagetsi harigone kuitwa, uye kubatana kwemagetsi hakugone kuitwa pakati pemotokari yemagetsi nemidziyo yemagetsi. Muchiitiko ichi, charger iri mubhodhi inenge iri muchimiro chekudzima magetsi.

2. Kuyedzwa kwekubviswa kwesimba rekuchaja system

Kana kugadzika kweSisitimu yekuchaja yemurwi wekuchaja weACKana zvikasashanda zvakanaka, michina yemagetsi inoburitsa magetsi, izvo zvinogona kukonzera kuvhunduka kwemagetsi uye kukuvara kwemunhu. Saka, kuyedza nekutarisa mapombi ekuchaja kwakakosha. Zvichienderana nezvinodiwa zvakaita seGB/T20324, GB/T 18487, uye NB/T 33008, kuyedza mapombi ekuchaja eAC kunosanganisira kuongororwa kwakajairika, kuyedza on-load circuit switching, uye kuyedza kusagadzikana kwekubatana. Uchishandisa BAIC EV200 semuenzaniso, kukanganisa kwekusagadzikana kwePE pamamiriro ekuchaja kwesystem kunoonekwa nekuyedza shanduko dzemagetsi ekupinda nekubuda kwechaja iri mubhodhi.

Muhurongwa hunoratidzwa muMufananidzo 3, ma terminal eCC neCP ari kuruboshwe rwechaja iri mubhodhi ane mitsara yesignali yekuchaja; PE ndiyo waya yepasi; uye L neN materminal e220V AC.

Materminal ari kurudyi rwedhayagiramu yekuchaja iri mubhodhi materminal ekutaurirana ane voltage shoma. Basa rawo guru nderekudzosera chiratidzo chekuchaja chiri mubhodhi kumutsetse wekusimbisa kubatana kweVCU, kumutsa mutsetse wechiratidzo chekumutsa kuchaja kuti umutse panel yemidziyo inoratidza mamiriro ekubatana, uye kuti charger imutse VCU neBMS. VCU inozomutsa panel yemidziyo kuti itange kuratidza mamiriro ekuchaja. Main relay akanaka neasina kunaka ari mukati mebhatiri remagetsi anodzorwa neBMS kuti avhare kuburikidza nemirairo kubva kuVCU, ichipedzisa maitiro ekuchaja bhatiri remagetsi. Nzvimbo iri pasi pechaja iri mubhodhi muMufananidzo 3, yakabatana nebhokisi rekudzora rine voltage yakawanda, ndiyo nzvimbo yeDC output terminal ine voltage yakawanda.

Mukuyedza kukanganisa kwePE grounding, ma current clamp maviri akashandiswa kuyera panguva imwe chete ma input ne output currents. PE open-circuit fault yakaiswa uchishandisa AC power supply yakagadzirwa nega. Kana PE line yaiwanzo grounded, grounding switch yaive ON. Ne current clamp yakaiswa pa L (kana N) line, AC input current yakayerwa ye on-board charger yaive inenge 16A. Neimwe current clamp yakaiswa pa DC output power terminal ye on-board charger, current yakayerwa yaive inenge 9A.

Waya yekugadzika yePE payakabviswa uye switch yekugadzika yadzima, AC input current yakayerwa yechaja iri mubhodhi yaive 0A, uye DC output power current yaivewo 0A. Pakudzokorodza bvunzo ye open-circuit, magetsi ese ari maviri akadzokera pakarepo ku0A. Iyi bvunzo ye open-circuit paPE terminal inoratidza kuti kana waya yekugadzika yePE yabviswa, hapana magetsi aripo pa input and output terminals yechaja iri mubhodhi, zvichireva kuti charger iri mubhodhi haisi kushanda saka haibudisi magetsi ane voltage yakawanda kubhokisi rekudzora rine voltage yakawanda, zvichidzivirira bhatiri remagetsi kuti risachaje.

Kudzivirira pasi pemapombi ekuchaja eAC kwakakosha. Pasina dziviriro yepasi, nzvimbo dzekuchaja dzinogona kukonzera njodzi yekuvhunduka kwemagetsi. Nekuda kwekudzivirirwa kwesekitori yekuchaja yega, kubatana hakugone kuiswa pakati pemotokari yemagetsi nemidziyo yemagetsi, uye charger iri mubhodhi haizoshande.
