Nyaya iyi inotaura nezvemagadzirirwo emagetsi emurwi wekuchaja weDC une pfuti mbiri, kujekesa misimboti yekushanda kwepfuti imwe chete uyemota dzemagetsi dzine pfuti mbiri dzinochaja, uye kupa zano rekudzora kubuda kwezvinobuda zvekuenzanisa uye kuchinjana kuchaja kwenzvimbo yekuchaja pfuti mbiri.
Kuti tivandudze hungwaru uye mhinduro chaiyo yekuchaja, chinyorwa chino chinotaurawo nezve dhizaini yesystem yekuchaja pile yakavakirwa paSTM32F407 main control chip ine Cortex M4 core uye sisitimu inoshanda yeFreeRTOS yakavharirwa.
Dhizaini ye topology yemagetsi yepombi dzekuchaja
Dhizaini yeMagadzirirwo
Iyi itsva inopa dhizaini yepfuti mbiriChaja yeDC EV, ine chinodzora chikuru, module yemagetsi, chiratidziro chemukati chemunhu nemuchina, muverengi wekadhi reIC, mita yemagetsi yakangwara,AC contactor, DC contactor, circuit breaker, surge protector, uye magetsi maviri e12V DC. Dhayagiramu yemagetsi yese yemurwi wekuchaja inoratidzwa pazasi. Dhizaini yekubatanidza magetsi pakati pemurwi wekuchaja nepfuti dzeA neB inoenderana nechiyero chenyika cheDC charging interfaces yezvishandiso zvekuchaja zvinofambisa magetsi zvemotokari dzemagetsi.
Musimboti wekushanda
Nzvimbo yekuchaja ine pfuti mbiriNzvimbo yekuchaja yeDC, ichishandisa mamodule emagetsi gumi akabatana pamwe chete, akagadzirwa nenzira mbiri dzekudzora kuchaja: kuchaja equalization uye kuchaja kwakatanhamara.
Kuchaja kwekuenzanisa: Pfuti dzose A neB dzinochaja panguva imwe chete, nepower modules dzinosvika mashanu dzinochaja kubva papfuti imwe neimwe.
Kuchaja kwakatsauka: Kana pfuti imwe chete iri kushanda, mamodule emagetsi anosvika gumi anogona kuchaja.
Mamodule emagetsi anogamuchira simba remagetsi reAC rezvikamu zvitatu, rakabatana nemudziviriri we surge, mita yemagetsi yeAC yezvikamu zvitatu, uye contactor yeAC. Mamodule emagetsi anoburitsa simba reDC. Bhatani rekumisa emergency rinowanikwawo pakupinda, zvichibvumira dziviriro yekumisa emergency nekucheka kupinda kwezvikamu zvitatu. Mutongi mukuru anotaura nemamodule emagetsi kuburikidza nebhazi reCAN kuti achinje mirairo yekudzora kubuda, uye mamodule emagetsi akabatanidzwawo kuburikidza nebhazi reCAN. Chiteshi ichi chine magetsi maviri e12V DC: rimwe rakabatana neA+ neA- pins dzepfuti yekuchaja kuti ripe simba rekubatsira remagetsi rakaderera kumotokari yemagetsi, uye rimwe richipa simba kuratidzwa kweinterface yemunhu-muchina.
Dhizaini yehurongwa hukuru hwekudzora
A. Dhizaini yeMabhuroko Anoshanda muSisitimu
Dhayagiramu huru yeblock system yekudzora inoratidzwa pazasi. Chip huru yekudzora yesystem iyi iSTM32F407ZGT6, ine ma peripheral interfaces akapfuma: 2 CAN, 4 USART, 2 UART, 1 Ethernet interface, nezvimwewo, zvinosangana nezvinodiwa zvekutanga zve charging pile control system yekudzora ma peripherals akadai se power modules, smart metres, IC card readers, uye touch screens.
B. Dhizaini yeDura reDura reDura reMain Control System
Izvi zvinosanganisira dhizaini yemaseketi ekubatanidza mabhazi eRS232, RS485, uye CAN.
