Dambudziko rehurongwa hwe800V: murwi wekuchaja wehurongwa hwekuchaja

800V yekuchaja "Zvinhu Zvekutanga Zvekuchaja"

Chinyorwa chino chinonyanya kutaura nezvezvimwe zvinodiwa zvekutanga zve800Vmirwi yekuchaja, ngatitangei tatarisa musimboti wekuchaja: Kana muromo wekuchaja wakabatana nemugumo wemotokari, murwi wekuchaja uchapa (1) simba reDC rinobatsira rakaderera kumugumo wemotokari kuti rishandise BMS yakavakirwa mukati (battery management system) yemotokari yemagetsi. Mushure mekushanda, (2) batanidza mugumo wemotokari kumugumo wemurwi, chinjana maparamita ekutanga ekuchaja akadai sesimba guru rekuchaja remugumo wemotokari uye simba guru rekubuda remugumo wemurwi, mushure mekunge mativi maviri aenderana nemazvo, BMS (battery management system) yemugumo wemotokari ichatumira ruzivo rwekuda kwesimba kunzvimbo yekuchaja yemagetsiuyemurwi wekuchaja mota yemagetsiichagadzirisa voltage yayo yekubuda uye current zvichienderana neruzivo urwu, uye ichatanga kuchaja mota zviri pamutemo, inova ndiyo musimboti wekutanga wekubatana kwekuchaja, uye tinofanira kutanga taziva nezvazvo.

Kuchaja kwe800V: "kuwedzera voltage kana current"

Panyaya yedzidziso, kana tichida kupa simba rekuchaja kuti tipfupise nguva yekuchaja, kazhinji pane nzira mbiri: kungava kuwedzera bhatiri kana kuwedzera voltage; Sekureva kweW=Pt, kana simba rekuchaja rakapetwa kaviri, nguva yekuchaja inoderedzwa nehafu; Sekureva kweP=UI, kana voltage kana current zvakapetwa kaviri, simba rekuchaja rinogona kupetwa kaviri, izvo zvataurwa kakawanda uye zvinoonekwa sezvine musoro.

Kana magetsi ari makuru, pachava nematambudziko maviri, magetsi ari kukura, tambo inoda magetsi ari kukura uye akawandisa, izvo zvichawedzera dhayamita yewaya nehuremu, zvinowedzera mutengo, uye hazvikodzeri vashandi kuti vashandise; Pamusoro pezvo, maererano neQ=I²Rt, kana magetsi ari pamusoro, kurasikirwa kwesimba kuri kukuru, uye kurasikirwa kwacho kunoratidzwa muchimiro chekupisa, izvo zvinowedzerawo kumanikidzwa kwekutonga kwekupisa, saka hapana mubvunzo kuti hazvikurudzirwi kuwedzera simba rekuchaja nekuwedzera magetsi ari mukati memota nguva dzose, kungave kuri kuchaja kana system yekutyaira mumota.

Zvichienzaniswa nekuchaja nekukurumidza kwemagetsi epamusoro,kuchaja nekukurumidza kwemagetsi ane simba guruinokonzera kupisa kushoma uye kurasikirwa kushoma, uye makambani emotokari akawanda akashandisa nzira yekuwedzera voltage, kana paine high-voltage fast charging, mukufunga kuti nguva yekuchaja inogona kupfupikiswa ne50%, uye kuwedzera kwevoltage kunogonawo kuwedzera simba rekuchaja kubva pa120KW kusvika pa480KW.

Kuchaja kwe800V: "Mhedzisiro yekupisa inoenderana nevoltage ne current"

Asi kungave kuri kuwedzera voltage kana kuwedzera current, kutanga, nekuwedzera kwesimba rako rekuchaja, kupisa kwako kuchaonekwa, asi kuratidzwa kwekupisa kwekuwedzera voltage nekuwedzera current kwakasiyana. Zvisinei, yekutanga ndiyo inosarudzwa kana tichienzanisa.

Nekuda kwekusasimba kwakaderera kunosangana nemagetsi emagetsi kana achipfuura nemumuchina wemagetsi, nzira yekuwedzera magetsi inoderedza saizi yetambo inodiwa, uye kupisa kunofanira kudzima kushoma, uye nepo magetsi achiwedzera, kuwedzera kwenzvimbo inotakura magetsi kunotungamira kudhayamita yekunze yakakura uye huremu hwetambo hukuru, uye kupisa kuchawedzera zvishoma nezvishoma nekuwedzerwa kwenguva yekuchaja, iyo yakavanzwa zvakanyanya, inova njodzi huru kubhatiri.

Kuchaja kwe800V: "Mamwe matambudziko aripo panguva iyoyo nemapombi ekuchaja"

Kuchaja nekukurumidza kwe800V kune zvimwe zvinodiwa zvakasiyana pamucheto wemurwi:

Kana kubva pakuona kwemuviri, nekuwedzera kwevoltage, saizi yekugadzira yemidziyo ine chekuita nayo ichawedzera, semuenzaniso, zvichienderana nehuwandu hwekusvibiswa kweIEC60664 iri 2 uye daro reboka rezvinhu zvinodzivirira kupisa riri 1, daro remudziyo une voltage yepamusoro rinofanira kuva kubva pa2mm kusvika 4mm, uye zvinodiwa zvakafanana zvekudzivirira kupisa zvichawedzerawo, daro rinenge re creepage uye zvinodiwa zvekudzivirira kupisa zvinoda kupetwa kaviri, izvo zvinoda kugadziriswa pakugadzira zvichienzaniswa nedhizaini yekare ye voltage system, kusanganisira zvinobatanidza, mabharu emhangura, zvinobatanidza, nezvimwewo. Pamusoro pezvo, kuwedzera kwevoltage kuchaitawo kuti pave nezvinodiwa zvepamusoro zvekudzima arc, uye zvakakosha kuwedzera zvinodiwa zvezvimwe zvishandiso zvakaita semafuse, mabhokisi ekuchinja, zvinobatanidza, nezvimwewo, izvo zvinoshandawo padhizaini yemota, izvo zvichataurwa muzvinyorwa zvinotevera.

Sisitimu yekuchaja ine voltage yepamusoro ye800V inofanira kuwedzera sisitimu yekutonhodza mvura inoshanda yekunze sezvambotaurwa pamusoro apa, uye kutonhodza kwemhepo kwechinyakare hakugone kuzadzisa zvinodiwa kungave kuri kutonhodza kunoshanda kana kusingashande, uye manejimendi yekupisa yenzvimbo yekuchaja mota yemagetsiMutsetse wepfuti kumagumo emotokari wakakwirawo kupfuura kare, uye maitiro ekuderedza nekudzora tembiricha yechikamu chino chesystem kubva padanho remudziyo uye nhanho yesystem ndiyo pfungwa inofanira kuvandudzwa nekugadziriswa nekambani yega yega mune ramangwana; Pamusoro pezvo, chikamu ichi chekupisa hachisi kupisa chete kunounzwa nekuchaja zvakanyanya, asiwo kupisa kunounzwa nemidziyo yemagetsi ine frequency yakakwira, saka maitiro ekutarisa panguva chaiyo uye kugadzikana, kushanda uye kwakachengeteka kubvisa kupisa kwakakosha zvikuru, izvo zvisiri kungobudirira muzvinhu chete, asiwo kuona kwakarongeka, senge kutarisa nguva chaiyo uye kushanda kwekupisa kwekuchaja.

Parizvino, voltage inobuda yeMirwi yekuchaja yeDCPamusika pane 400V, iyo isingakwanise kuchaja zvakananga bhatiri re800V, saka chimwe chigadzirwa chekuwedzera cheDCDC chinodiwa kuti bhatiri re400V rikwire kusvika ku800V, uye wobva wachaja bhatiri, izvo zvinoda simba rakawanda uye switching yepamusoro-soro, uye module inoshandisa silicon carbide kutsiva IGBT yechinyakare ndiyo sarudzo huru iripo, kunyangwe maSilicon carbide modules anogona kuwedzera simba rekubuda kwemapombi ekuchaja uye kuderedza kurasikirwa, asi mutengo wacho wakakwirawo zvakanyanya, uye zvinodiwa zveEMC zvakakwirawo.

Muchidimbu, kuwedzera kwemagetsi kuchada kuwedzerwa padanho resisitimu nedanho remudziyo, kusanganisira sisitimu yekutarisira kupisa, sisitimu yekudzivirira kuchaja, nezvimwewo, uye danho remudziyo rinosanganisira kuvandudzwa kwezvimwe zvishandiso zvemagineti nemidziyo yemagetsi.
