Gudaha gaariga wuxuu ka kooban yahay qaybo badan, gaar ahaan ka dib markii la iibiyo. Ujeedada masraxa korantada waa in la isbarbar dhigo baahiyaha awoodda ee qaybaha kala duwan. Qaybaha qaarkood waxay u baahan yihiin koronto yar, sida elektiroonigga jirka, qalabka madadaalada, kontoroolada, iwm.koronto sare, sida nidaamyada baytariga, nidaamyada wadista korantada ee korantada, nidaamyada lagu dallaco, iwm.
Ka dib caddee xiriirka ka dhexeeya 800V iyo khidmadda si dhakhso leh: Hadda gaariga rakaabka ee korantada ee korantada ayaa guud ahaan ku dhawaad 400V nidaamka batari, qalabka korantada ee sare, haddii korantada korantada la taaban karo, ay taasi tahay Iyada oo la adeegsanayo isku-darka awoodda, hadda waa la dhimi karaa nus, oo lumiya nidaamka oo dhami ayaa yaraada, laakiin sidoo kale waa mid fudud, laakiin sidoo kale dheelitirka weyn, waxqabadka gaariga ayaa ah caawimaad weyn.
Xaqiiqdii, dacwad deg-deg ah ma aha mid si toos ah loo xidhiidha 800V, sababta oo ah heerka lacag-bixinta ayaa ka sarreeya, taas oo aan wax xiriir ah ku lahayn 800V, kaliya waxay la mid tahay tacliinta Tesla, laakiin sidoo kale waxay ku guuleysan kartaa si dhakhso leh Ku dallaca qaab sare oo hadda jira. Laakiin 800V waa in la gaaro lacag-bixin koronto-sare ah waxay siisaa aasaas wanaagsan, maxaa yeelay isku mid ayaa ku guuleysata 350kw oo ah 400KW, waxay u baahan tahay 900A hadda, 900A ee xaaladaha farsamada ee hadda jira ee gawaarida rakaabka ah. Inta badan wax aan macquul aheyn. Sidaa darteed, waa wax macquul ah in la isku xidho 800V iyo si wada jir ah oo aad u wada yeeshaan kharashka degdegga ah ee weyn, oo loo yaqaan 800v Super si dhakhso leh u dallac.
Waqtigan xaadirka ah, waxaa jira saddex nooc oo ahkoronto sareQaab-dhismeyaasha Nidaamka ee laga filayo in lagu gaaro lacag koronto oo sare oo sare, oo nidaamka korantada oo buuxa ayaa la filayaa inuu noqdo guud ahaan:
(1) Nidaamka buuxa ee korantada, taasi waa, 800v oo ah 800V matoor, korantada matoor, korantada + 800v obc, DC / DC, PDU + 800V hawada, PTC.
Faa'iidooyinka: Heerka beddelka tamarta sare, tusaale ahaan, heerka beddelka tamarta ee nidaamka korontada ayaa ah 90%, heerka guud ee tamarta ee DC / DC waa 92%, ma ahan lagama maarmaan in lagu niyad jabiyo DC / DC, heerka beddelka tamarta beddelka ah waa 90% × 92% = 82.8%.
Daciifnimada: qaab dhismeedka aan lahayn shuruudo sare oo ku saabsan nidaamka batteriga, korantada, obp, aaladda korantada ee DC / DC-da, PTC, PTC, iwm, iwm, iwm. , kororka kharashka gawaarida muddada-gaaban ayaa ka sarreeya, laakiin muddada dheer, ka dib marka silsiladda warshaduhu qaan gaadhay iyo saamaynta cabbirka ayaa leh. Cabbirka qaybo ka mid ah waa la yareeyaa, hufnaanta tamarta ayaa la hagaajiyaa, qiimaha gaarigana wuu dhici doonaa.
(2) qayb ka mid ahkoronto sare, taasi waa, 800V oo ah 400V matoor, korantada korantada + 400v obc, DC / DC, PDU + 400V hawada, PTC.
Faa'iidooyinka: Asal ahaan isticmaal qaab-dhismeedka jira, kaliya kor u qaadida batariga korantada, qiimaha isbadalka gawaarida waa yar yahay, oo waxaa jira wax ku oolnimo weyn muddada gaaban.
Faa'iido darrooyinka: DC / DC-ga-kor-u-dhaca ayaa loo isticmaalaa meelo badan, oo lumiya tamarta ayaa weyn.
(3) Dhamaan qaab dhismeedka koranta-yar, taasi waa, 400v batari (oo lagu dallaco 300v oo taxane ah, korantada) + 400v oo isbarbar dhigaya + 400v + 400V, qaboojiyaha, PTC + 400V.
Faa'iidooyinka: Isbadalka dhamaadka gawaarida waa yar yahay, baytarigu waxay u baahan tahay oo keliya in la beddelo BMS.
Faa'iido darrooyinka: Kordhinta taxanaha, kororka batteriga, isticmaal batteriga korantada asalka ah, hagaajinta hufnaanta hufnaanta ayaa xadidan.
