Nheyo yekushanda kweDC Charging Piles yeMotokari Itsva dzeSimba

1. Kupatsanurwa kwemapombi ekuchaja

IyoMurwi wekuchaja weACinogovera simba reAC kubva kugridi remagetsi kuenda kumodule yekuchajayemotokari kuburikidza nekutaurirana nemotokari, uyemodule yekuchajapamotokari inodzora simba rekuchaja bhatiri remagetsi kubva kuAC kuenda kuDC.

IyoPfuti yekuchaja yeAC (Type1, Type2, GB/T) yeNzvimbo dzekuchaja dzeACine maburi manomwe ekugumira, maburi manomwe ane maburi esimbi anotsigira matatu-phaseNzvimbo dzekuchaja mota dzemagetsi dzeAC(380V), maburi manomwe ane maburi mashanu chete ane materminal esimbi ari muchikamu chimwe cheteChaja yeAC ev(220V), pfuti dzekuchaja dzeAC diki panePfuti dzekuchaja dzeDC (CCS1, CCS2, GB/T, Chademo).

IyoMurwi wekuchaja weDCInoshandura simba reAC regrid remagetsi kuita simba reDC kuti ichajise bhatiri remagetsi remotokari nekushandisa ruzivo nemotokari, uye inodzora simba rekubuda kwemurwi wekuchaja zvichienderana nemaneja webhatiri ari pamotokari.

Pane maburi mapfumbamwe ekupedzisira papfuti yekuchaja yeDCNzvimbo dzekuchaja dzeDC, uye pfuti yekuchaja yeDC yakakura kupfuura pfuti yekuchaja yeAC.

2. Nheyo huru yekushanda kwemapombi ekuchaja eDC

Mumutemo weindasitiri wekuti “NB/T 33001-2010: Mamiriro eUnyanzvi eKuchaja Madhiraivha eMotokari Dzisina Kuiswa Muchikepe” wakapihwa neNational Energy Administration, zvakataurwa kuti chimiro chikuru cheChaja yemagetsi yeDCinosanganisira: power unit, control unit, metering unit, charger interface, power supply interface uye human-computer interaction interface. Power unit inoreva DC charging module, uye control unit inoreva charging pile controller. Sechigadzirwa chekubatanidza system, pamusoro pezvikamu zviviri zve "DC yekuchaja module"uye"chinodzora murwi wekuchaja"Ichiumba musimboti wehunyanzvi, dhizaini yechivakwa ndeimwe yepfungwa huru dzekugadzira kuvimbika kwemurwi wese. "Charging pile controller" iri muchikamu che embedded hardware ne software technology, uye "DC charging module" inomiririra kubudirira kwepamusoro-soro kwetekinoroji yemagetsi emagetsi mumunda we AC/DC.

Maitiro ekutanga ekuchaja ndeaya: kurodha DC voltage kumativi ese ebhatiri, kuchaja bhatiri ne constant high current, voltage yebhatiri inokwira zvishoma nezvishoma, inokwira kusvika pamwero wakati, voltage yebhatiri inosvika panhamba yepamusoro, SoC inosvika 95% (yemabhatiri akasiyana, akasiyana), uye inoramba ichichaja bhatiri ne constant voltage uye small current. "Voteji inokwira, asi bhatiri harina kuzara, kureva kuti, harina kuzara, kana paine nguva, unogona kuchinja kune small current kuti uiwedzere." Kuti uite izvi zvekuchaja, charger pile inoda kuva ne "DC charging module" kuti ipe DC power maererano nebasa; Zvakakosha kuva ne "charging pile controller" kuti idzore "power-on, shutdown, output voltage, uye output current" yecharging module; Zvakakosha kuva ne "touch screen" se human-machine interface kuti ibudise mirairo, uye controller ichaburitsa mirairo yakaita se "power on, shutdown, output voltage, output current" uye mimwe mirairo ku charging module. Zviri nyore murwi wekuchaja mota yemagetsiZvinonzwisiswa kubva padanho remagetsi zvinongoda kuva nemodule yekuchaja, bhodhi rekudzora uye skrini yekubata; Kana mirairo yakaita seyekudzima, kudzima uye voltage yekubuda] yagadzirwa kuita makiyibhodhi akati wandei pamodule yekuchaja, saka module yekuchaja inogona kuchaja bhatiri.

Iyochikamu chemagetsi chechaja yeDCine dunhu rekutanga nedunhu rechipiri. Chinopinzwa mudenderedzwa guru imagetsi matatu alternating current, ayo anoshandurwa kuita magetsi akananga anogamuchirwa nemodule yekuchaja (rectifier module) mushure meinput circuit breaker neAC smart energy meter, uye obva abatanidza fuse nepfuti yekuchaja yeEVkuchaja mota yemagetsi. Dunhu rechipiri rinemurwi wekuchaja mota yemagetsichinodzora, muverengi wemakadhi, sikirini yekuratidza, DC meter, nezvimwewo. Dunhu rechipiri rinopawo kudzora kwe "kutanga-kumisa" uye "kumira kwekukurumidzira"; Chiedza chechiratidzo chinopa zviratidzo zve "standby", "charging" uye "full"; Semudziyo wekudyidzana kwevanhu nekombuta, chiratidziro chinopa kutsvaira kadhi, kugadzirisa nzira yekuchaja uye mashandiro ekudzora kwe "start-stop".

Nheyo yemagetsi yeDC charging piles inopfupikiswa seinotevera:

• Module imwe chete yekuchaja parizvino ine simba re15kW chete, iyo isingakwanise kuzadzisa zvinodiwa nemagetsi, uye inoda mamodule akawanda ekuchaja kuti ashande pamwe chete panguva imwe chete, uye inoda bhazi reCAN kuti iwane kugovana kwemamodule akawanda pari zvino;
• Kupinza kwemodule yekuchaja kunobva pagrid yemagetsi, inova simba guru remagetsi, rinosanganisira grid yemagetsi uye kuchengetedzeka kwemunhu, kunyanya kuchengetedzeka kwemunhu, zvakakosha kuisa switch yemhepo (zita resainzi ndi "plastic shell circuit breaker"), switch yekudzivirira mheni kana kunyange switch yekubuda kwemvura pamucheto wekupinda;
• Kubuda kwemurwi wekuchaja kune voltage yakakwira uye simba remagetsi rakakwira, bhatiri rine electrochemical, riri nyore kuputika, kudzivirira kusashanda zvakanaka, kubuda kwacho kunofanira kunge kune fuse;
• Nyaya dzekuchengetedza ndidzo dzinonyanya kukosheswa, pamusoro pezviyero zviri kumagumo ekupinda, makiyi emakanika nemakiyi emagetsi zvinofanira kunge zviripo, kuyedzwa kwekudzivirira kuputirwa kwemhepo kunofanira kunge kuripo, uye kuramba kuburitswa kwemhepo kunofanira kunge kuripo;
• Kana bhatiri richibvuma kuchaja hazvionekwi nehurongwa hwekuchaja, asi nepfungwa dzebhatiri, BMS. BMS inopa mirayiridzo kumutongi we "kana richibvumira kuchaja, kana richimisa kuchaja, kuti voltage yakawanda sei uye current zvinogona kugamuchirwa", uye mutongi webhatiri anobva atumira kumodule yekuchaja. Saka, zvakakosha kuita kutaurirana kweCAN pakati pemutongi webhatiri neBMS, uye kutaurirana kweCAN pakati pemutongi webhatiri nemodule yekuchaja;
• Murwi wekuchaja unofanirawo kutariswa nekutarisirwa, uye chinodzora chinofanira kubatanidzwa kumashure kuburikidza neWiFi kana 3G/4G nedzimwe module dzekutaurirana netiweki;
• Bhiri remagetsi rekuchaja harisi remahara, uye mita inofanira kuiswa, uye muverengi wekadhi anodiwa kuti aite basa rekubhadhara;
• Panofanira kuva nechiedza chekuratidza chakajeka paganda rekuchaja, kazhinji mwenje mitatu yekuratidza, iyo inoratidza kuchaja, kukanganisa uye simba remagetsi zvichiteerana;
• Kugadzirwa kwemigero yemhepo yemapombi ekuchaja eDC kwakakosha. Kuwedzera paruzivo rwemagadzirirwo, dhizaini yemigero yemhepo inoda kuti feni iiswe mumugero wekuchaja, kunyangwe paine feni mukati memodule yega yega yekuchaja.
