Kushanda Nheyo yeDC Kuchaja Mirwi yeMotokari Itsva

1. Kurongeka kwekuchaja mirwi

TheAC kuchaja murwiinogovera iyo AC simba kubva kune yemagetsi grid kusvika kunekuchaja moduleyemotokari kuburikidza nekudyidzana kweruzivo nemotokari, uyekuchaja modulepamotokari inodzora simba rekuchaja bhatiri remagetsi kubva kuAC kuenda kuDC.

TheAC yekuchaja pfuti (Type1, Type2, GB/T) nokutiAC yekuchaja zviteshiine 7 maburi maburi, 7 maburi ane simbi terminals kutsigira matatu-phaseAC yemagetsi mota yekuchaja zviteshi(380V), 7 maburi ane 5 maburi ane simbi terminals ari single-phaseAC ev charger(220V), AC yekuchaja pfuti idiki paneDC kuchaja pfuti(CCS1, CCS2, GB/T, Chademo).

TheDC yekuchaja murwiinoshandura iyo AC simba regedhi remagetsi kuita DC simba rekuchaja bhatiri remagetsi remotokari nekubatana nemotokari neruzivo, uye inodzora simba rekubuda remurwi wekuchaja zvinoenderana nemaneja webhatiri pamotokari.

Pane 9 maburi maburi paDC yekuchaja pfutiDC yekuchaja zviteshi, uye pfuti yekuchaja yeDC yakakura kudarika pfuti yekuchaja yeAC.

2. Iyo yakakosha kushanda musimboti weDC yekuchaja mirwi

Muchikamu cheindasitiri "NB/T 33001-2010: Technical Conditions for Non-on-board Conduction Chargers for Electric Vehicles" yakapihwa neNational Energy Administration, inoratidzwa kuti iyo yekutanga kuumbwa kweDC ev chargerzvinosanganisira: simba unit, control unit, metering unit, kuchaja interface, magetsi ekupa interface uye yemunhu-kombuta yekudyidzana interface. Iyo magetsi unit inoreva iyo DC yekuchaja module, uye iyo control unit inoreva yekuchaja murwi controller. Sechigadzirwa chekubatanidza system, kuwedzera kune izvo zviviri zvikamu zve "DC yekuchaja module” uye “kuchaja murwi controller”ichiumba hunyanzvi hwehunyanzvi, dhizaini yekugadzira zvakare imwe yeakakosha mapoinzi ekuvimbika dhizaini yemurwi wese. "Kuchaja murwi controller" ndewechikamu cheyakamisikidzwa hardware uye software tekinoroji, uye "DC yekuchaja module" inomiririra kubudirira kwepamusoro kwesimba remagetsi tekinoroji mumunda we AC/DC.

Maitiro ekutanga ekuchaja ndeaya: kurodha DC voltage kumagumo ese ebhatiri, kuchaja bhatiri neanogara akakwira ikozvino, vhezheni yebhatiri zvishoma nezvishoma uye zvishoma nezvishoma inosimuka, ichikwira kusvika pamwero wakati, bhatiri remagetsi rinosvika pamutengo wezita, iyo SoC inosvika 95% (yemabhatiri akasiyana, akasiyana), uye inoramba ichichaja bhatiri nemagetsi anogara aripo uye diki ikozvino. "Voteji inokwira, asi bhatiri harina kuzara, kureva kuti harina kuzara, kana paine nguva, unogona kushandura kuita diki ikozvino kuti upfume." Kuti uone nzira yekuchaja iyi, murwi wekuchaja unofanirwa kuve ne "DC yekuchaja module" kuti ipe DC simba maererano nebasa; Izvo zvinodikanwa kuve ne "kuchaja murwi controller" kudzora "simba-pa, kudzima, kubuda kwemagetsi, uye kubuda ikozvino" kweiyo yekuchaja module; Izvo zvinodikanwa kuve ne "touch screen" seyemunhu-muchina interface kuti uburitse mirairo, uye controller ichaburitsa mirairo yakadai se "simba pa, shutdown, kubuda voltage, kubuda ikozvino" uye mamwe mirairo kune yekuchaja module. The simplest mota yemagetsi yekuchaja murwiinonzwisiswa kubva pachiyero chemagetsi chinongoda kuve nechaji module, control board uye touch screen; Kana iyo mirairo senge simba pa, shutdown uye inobuda voltage] inobuda ikozvino inogadzirwa kuita akati wandei makiyibhodhi pane yekuchaja module, ipapo yekuchaja module inogona kuchaja bhatiri.

Thechikamu chemagetsi che DC chargerine yepuraimari sedunhu uye yechipiri dunhu. Iko kupinza kweiyo main loop ndeye matatu-phase alternating ikozvino, iyo inoshandurwa kuita yakatwasuka ikozvino inogamuchirwa nechaji module (rectifier module) mushure meiyo yekuisa circuit breaker uye AC smart simba mita, uyezve inobatanidza fuse uye.ev charger pfutikuchaja motokari yemagetsi. Dunhu rechipiri rine amota yemagetsi yekuchaja murwicontroller, muverengi wekadhi, chidzitiro chekuratidzira, mita yeDC, etc. Chikamu chechipiri chinopawo "kutanga-stop" kutonga uye "emergency stop" kushanda; Chiedza chechiratidzo chinopa "standby", "charging" uye "full" mamiriro ezviratidzo; Semunhu-kombuta yekudyidzana mudziyo, chiratidziro chinopa kadhi swiping, yekuchaja modhi yekumisikidza uye kutanga-kumisa kudzora maitiro.

Iyo yemagetsi musimboti weDC yekuchaja mirwi inopfupikiswa seizvi:

• Imwe chete yekuchaja module parizvino ingori 15kW chete, iyo isingakwanisi kusangana nezvinodiwa zvemagetsi, uye inoda akawanda mamodule ekuchaja kuti ashande pamwe chete akafanana, uye inoda kuve neCAN bhazi kuti iwane ikozvino kugoverana kwemamodule akawanda;
• Iko kupinza kweiyo module yekuchaja kunobva kune gidhi remagetsi, iro rine simba guru-simba rekupa, rinosanganisira giredhi remagetsi uye kuchengetedzwa kwemunhu, kunyanya kuchengetedzwa kwemunhu, zvinodikanwa kuisa switch yemhepo (zita resainzi "plastic shell circuit breaker"), kushandura mheni yekudzivirira kana kunyange kushandura kwekuvhara pamagumo ekupinza;
• Kubuda kwemurwi wekuchaja ndeye high voltage uye yakakwira ikozvino, bhatiri ndeye electrochemical, nyore kuputika, kudzivirira kuchengetedzwa kwemisoperation, kubuda kunofanirwa kunge kune fuse;
• Nyaya dzekuchengetedza ndidzo dzinonyanya kukoshesa, mukuwedzera kumatanho ari pamagumo ekuisa, makiyi emagetsi uye makiyi emagetsi anofanirwa kunge aripo, kuyedzwa kwekudzivirira kunofanirwa kuvepo, uye kuramba kubuda kunofanirwa kuvepo;
• Kunyangwe bhatiri richibvuma kuchaja hazvitariswe nemurwi wekuchaja, asi nehuropi hwebhatiri, BMS. Iyo BMS inopa mirairo kune controller ye "kutendera kubhadharisa, kana kumisa kuchaja, yakawanda sei voltage uye ikozvino inogona kugamuchirwa", uye mutongi anobva aiendesa kune yekuchaja module. Naizvozvo, zvinodikanwa kuita CAN kutaurirana pakati pemutongi neBMS, uye CAN kutaurirana pakati pemutongi uye yekuchaja module;
• Murwi wekuchaja unodawo kutariswa uye kutariswa, uye mutongi anoda kubatanidzwa kumashure kuburikidza neWiFi kana 3G/4G uye mamwe mamodule ekutaurirana network;
• Mari yemagetsi yekuchaja haisi yemahara, uye mita inoda kuiswa, uye muverengi wekadhi anodiwa kuti aone basa rekubhadhara;
• Panofanirwa kuve nechiedza chakajeka chemwenje pagomba rekuchaja, kazhinji marambi matatu anoratidza, anoratidza kuchaja, kukanganisa uye magetsi zvichiteerana;
• Iyo mhepo duct dhizaini yeDC yekuchaja mirwi ndiyo yakakosha. Pamusoro peruzivo rwechimiro, dhizaini yemhepo inoda kuti fan iiswe mumurwi wekuchaja, kunyangwe paine feni mukati memodhi yega yega yekuchaja.
