800V yekuchaja murwi "Charging Basics"
Ichi chinyorwa chinonyanya kutaura nezve zvimwe zvekutanga zvinodiwa zve800Vkuchaja mirwi, chokutanga ngatitarisei nheyo yekuchaja: Kana iyo yekuchaja yakabatana kumagumo emotokari, murwi wekuchaja uchapa (1) yakaderera-voltage anobatsira DC simba kumagumo emotokari kumisa yakavakirwa-mukati BMS (bhatiri manejimendi system) yemotokari yemagetsi Mushure mekuita activation, (2) batanidza iyo yekutsinhana yemotokari kumagumo emagetsi ekuchaja seyakanyanya kudhirowa. iyo yekupedzisira yemotokari uye iyo yakanyanya kuburitsa simba remurwi kupera, mushure mekunge mativi maviri afananidzwa nemazvo, iyo BMS (bhatiri manejimendi system) yekuguma kwemotokari inotumira ruzivo rwekuda kwesimba kuneev kuchaja chiteshi,uyemota yemagetsi yekuchaja murwiichagadzirisa yayo yega inobuda voltage uye yazvino zvinoenderana neruzivo urwu, uye kutanga zviri pamutemo kuchaja mota, inova ndiyo musimboti wekuchaja kubatana, uye tinofanira kutanga tajairana nazvo.
800V kuchaja: "boost voltage kana ikozvino"
Theoretically, kana tichida kupa simba rekuchaja kupfupisa nguva yekuchaja, pane kazhinji nzira mbiri: kana iwe unowedzera bhatiri kana kuwedzera voltage; Zvinoenderana neW=Pt, kana simba rekuchaja rakapetwa kaviri, nguva yekuchaja inozove nepakati; Zvinoenderana neP = UI, kana iyo voltage kana ikozvino yakapetwa kaviri, iyo yekuchaja simba inogona kupetwa kaviri, iyo yave ichitaurwa kakawanda uye inoonekwa seyakajairika.
Kana ikozvino yakakura, pachava nezvinetso zviviri, iyo yakakura ikozvino, yakakura uye yakawanda tambo inoda ikozvino, iyo inowedzera dhayamita yewaya uye uremu, kuwedzera mari, uye haisi nyore kuti vashandi vashande; Pamusoro pezvo, zvinoenderana neQ=I²Rt, kana yazvino yakakwira, kurasikirwa kwesimba kwakakura, uye kurasikirwa kunoratidzwa nenzira yekupisa, izvo zvinowedzerawo kudzvanywa kwekutonga kwemafuta, saka hapana kupokana kuti hazvikurudzirwe kuwedzera simba rekuchaja nekuramba uchiwedzera yazvino, ingave ichichaja kana in-mota drive system.
Kuenzaniswa nekuchaja kwepamusoro-ikozvino,high-voltage fast kuchajainogadzira kupisa kushoma uye kurasikirwa kwakadzikira, uye makambani emotokari anenge akajairika atora nzira yekuwedzera voltage, kana iri high-voltage kukurumidza kuchaja, zvichireva kuti nguva yekuchaja inogona kupfupikiswa ne50%, uye kuwedzera kwevoltage kunogona zvakare kuwedzera nyore kuchaja simba kubva pa120KW kusvika 480KW.
800V kuchaja: "Thermal mhedzisiro inoenderana nevoltage uye yazvino"
Asi kana iri kuwedzera magetsi kana kuwedzera ikozvino, kutanga kwezvose, nekuwedzera kwesimba rako rekuchaja, kupisa kwako kuchaonekwa, asi kuratidzwa kwekushisa kwekuwedzera kwemhepo uye kuwedzera ikozvino kwakasiyana. Zvisinei, iyo yekutanga inonyatsonaka mukuenzanisa.
Nekuda kwekupikiswa kwakaderera kunosangana neazvino kana uchipfuura nemu conductor, nzira yekuwedzera voltage inoderedza saizi inodiwa yetambo, uye kupisa kunofanira kubviswa kushoma, uye nepo ikozvino ichiwedzerwa, kuwedzera kweiyo-inotakura-inotakura-inotenderera nzvimbo inotungamira kune yakakura yekunze dhayamita uye hombe tambo uremu, uye kupisa kunowedzera zvishoma nezvishoma nekuwedzera kweiyo bhatiri yekuchaja, iyo inova njodzi huru kune iyo bhatiri, iyo inova nguva yakawanda yekuchaja.
800V kuchaja: "Mamwe matambudziko ekukurumidza nemapiru ekuchaja"
800V inokurumidza kuchaja zvakare ine zvimwe zvakasiyana zvinodiwa pamurwi wekupedzisira:
Kana kubva pakuona kwemuviri, nekuwedzera kwevoltage, saizi yedhizaini yemidziyo ine hukama inosungirwa kuwedzera, semuenzaniso, zvinoenderana nedanho rekusvibiswa kweIEC60664 iri 2 uye chinhambwe cheboka rekuchengetedza zvinhu chiri 1, chinhambwe cheiyo-high-voltage mudziyo unofanirwa kubva pa2mm kusvika 4mm, uye zvakafanana zvinodzivirira kudzivirira zvinodikanwa zvichawedzerawo uye dhizaini inodiwa kuti igadziriswe zvakare mapeji. dhizaini yakaenzaniswa neyakapfuura voltage system dhizaini, kusanganisira majoini, mabhawa emhangura, majoini, nezvimwe. Pamusoro pezvo, kuwedzera kwevoltage kunotungamira kune zvakakwirira zvinodikanwa zvekudzima arc, uye zvinodikanwa kuwedzera zvinodikanwa zvemimwe michina yakaita semafuse, mabhokisi ekuchinja, majoini, nezvimwewo, izvo zvinoshandawo pakugadzirwa kwemota, izvo zvichazotaurwa muzvinyorwa zvinotevera.
Iyo yakakwira-voltage 800V yekuchaja sisitimu inoda kuwedzera yekunze inoshanda yemvura kutonhora sisitimu sezvataurwa pamusoro, uye yechinyakare mhepo kutonhora haigone kuzadzisa zvinodiwa ingave iri kushanda kana kungotonhora kutonhora, uye kutonga kwekupisa kweiyo.electric car charging stationmutsara wepfuti kusvika kumagumo emotokari zvakare wakakwira kupfuura kare, uye maitiro ekudzikisa uye kudzora tembiricha yechikamu ichi chegadziriro kubva padanho remuchina uye nhanho yehurongwa ndiyo poindi inofanirwa kuvandudzwa uye kugadziriswa nekambani imwe neimwe mune ramangwana; Mukuwedzera, chikamu ichi chekupisa hachisi chete kupisa kunounzwa nekuwedzerwa, asiwo kupisa kunounzwa ne-high-frequency power devices, saka maitiro ekuita chaiyo-nguva yekucherechedza uye yakagadzikana, inoshanda uye yakachengeteka kubvisa kupisa kunokosha zvikuru, iyo haisi kungobudirira mune zvigadzirwa, asiwo kuongorora kwakarongeka, zvakadai se-chaiyo-nguva uye inobudirira kutarisa kwekuchaja tembiricha.
Parizvino, iyo yakabuda voltage yeDC kuchaja mirwipamusika ndeye 400V, iyo isingakwanise kubhadharisa bhatiri remagetsi 800V, saka chinodiwa kuwedzera DCDC chigadzirwa kusimudza 400V voltage kusvika 800V, uye wozochaja bhatiri, iro rinoda simba repamusoro uye high-frequency switching, uye module inoshandisa silicon carbide kutsiva iyo yechinyakare IGBT ndiyo yazvino inokonzeresa sarudzo yemagetsi, kunyange zvazvo magetsi emagetsi anowedzera. kuderedza kurasikirwa, asi mutengo zvakare wakakwira zvakanyanya, uye zvinodiwa zveEMC zvakare zvakakwirira.
Kuzvipfupikisa. Chaizvoizvo, kuwedzera kwevoltage kunoda kuwedzerwa padanho rehurongwa uye nhanho yechishandiso, kusanganisira thermal manejimendi system, yekuchaja yekudzivirira system, nezvimwewo, uye nhanho yechishandiso inosanganisira kuvandudzwa kwemamwe magineti zvishandiso nemagetsi.
