Mukati memotokari inoumbwa nezvinhu zvakawanda, kunyanya mushure mekugadzirwa kwemagetsi.Chinangwa chepuratifomu yevoltage ndeyekuenderana nezvinodiwa zvemagetsi zvezvikamu zvakasiyana.Zvimwe zvikamu zvinoda simba rakaderera, semagetsi emuviri, midziyo yevaraidzo, zvidzori, nezvimwewo (kazhinji 12V voltage papuratifomu magetsi), uye zvimwe zvinoda zvishoma.moto muzhinji, zvakadai semabhatiri system, high voltage drive systems, kuchaja masisitimu, nezvimwewo (400V / 800V), saka kune yakakwirira voltage platform uye low voltage platform.
Wobva wajekesa hukama huri pakati pe800V uye super fast charge: Ikozvino mota yemagetsi yemutakuri inowanzoita 400V bhatiri system, mota inoenderana, zvishongedzo, high voltage tambo zvakare yakafanana voltage level, kana system voltage yakawedzera, zvinoreva kuti pasi pekuda kwesimba rimwe chete, ikozvino inogona kuderedzwa nehafu, iyo yose yehurongwa kurasikirwa inova diki, kupisa kunoderedzwa, asiwo kuwedzera kureruka, kuita kwemotokari kunobatsira zvikuru.
Sezvineiwo, kukurumidza kuchaja haina hukama zvakananga ne800V, kunyanya nekuti chiyero chekuchaja chebhatiri chakakwira, ichibvumira kuchaja kwesimba guru, iro pacharo harina chekuita ne800V, senge Tesla's 400V papuratifomu, asi inogona zvakare kuwana nekukurumidza zvakanyanya. kuchaja muchimiro chepamusoro-soro.Asi 800V ndeyekuwana yakakwira-simba yekuchaja inopa hwaro hwakanaka, nekuti zvakafanana kuti uwane 360kW yekuchaja simba, 800V dzidziso inongoda 450A ikozvino, kana iri 400V, inoda 900A ikozvino, 900A mune yazvino tekinoroji mamiriro emotokari dzinotakura. zvinenge zvisingaiti.Naizvozvo, zvine musoro kubatanidza 800V uye super fast charge pamwe chete, inonzi 800V super fast charge technology platform.
Parizvino, kune marudzi matatu emoto muzhinjimasisitimu ekuvaka anotarisirwa kuwana yakakwira-simba nekukurumidza kuchaja, uye iyo yakazara yakakwira-voltage system inotarisirwa kuve iyo huru:
(1) Full system high voltage, kureva, 800V simba bhatiri + 800V motokari, magetsi ekutonga +800V OBC, DC / DC, PDU + 800V air conditioning, PTC.
Zvakanakira: High simba rekushandura chiyero, semuenzaniso, iyo simba rekushandura chiyero chemagetsi drive system i90%, iyo simba rekushandura chiyero cheDC / DC i92%, kana iyo system yese iri yakakwira voltage, hazvifanirwe kudzvinyirira kuburikidza. DC/DC, iyo system simba rekushandura chiyero ndeye 90% × 92% = 82.8%.
Kushaya simba: Iyo dhizaini haingove nepamusoro zvinodiwa pabhatiri system, kutonga kwemagetsi, OBC, DC/DC magetsi emagetsi anoda kutsiviwa neSi-based IGBT SiC MOSFET, mota, compressor, PTC, nezvimwe zvinoda kuvandudza mashandiro emagetsi. , yenguva pfupi yemotokari yekupedzisira mutengo wekuwedzera wakakwira, asi nekufamba kwenguva, mushure mekunge cheni yeindasitiri yakura uye chiyero chave nacho.Huwandu hwezvimwe zvikamu hwakaderedzwa, kushanda kwesimba kunovandudzwa, uye mutengo wemotokari unodonha.
(2) Chikamu chemoto muzhinji, kureva, 800V bhatiri +400V mota, magetsi ekudzora +400V OBC, DC/DC, PDU +400V air conditioning, PTC.
Zvakanakira: kunyanya shandisa chimiro chiripo, kusimudzira chete bhatiri remagetsi, mutengo wekupedzisira wemotokari shanduko idiki, uye kune hukuru hunoshanda munguva pfupi.
Zvakaipa: DC/DC danho-pasi rinoshandiswa munzvimbo dzakawanda, uye kurasikirwa kwesimba kwakakura.
(3) Yese yakaderera-voltage architecture, kureva, 400V bhatiri (kuchaja 800V munhevedzano, kuburitsa 400V mune parallel) +400V mota, magetsi ekudzora +400V OBC, DC/DC, PDU +400V air conditioning, PTC.
Mabhenefiti: Iyo mota yekupedzisira shanduko idiki, bhatiri rinongoda kushandurwa BMS.
Zvakaipa: kuwedzera kwenhevedzano, kuwedzera kwemutengo webhatiri, shandisa bhatiri remagetsi rekutanga, kuvandudzwa kwekuchaja kwakanaka kunogumira.
