Nyob rau hauv thawj xyoo ntawm High-voltage Fast Charging, Them Cov Pile Zoo siab txais tos tshiab lub sijhawm rau kev loj hlob
Lub charger pawg yog ib qho cuab yeej uas muab hluav taws xob ntxiv rau lub tsheb tshiab lub zog (xws li hluav taws xob ntshiab thiab plug-in hybrid). Nws muaj nuj nqi zoo ib yam li cov roj dispenser hauv qhov chaw nres tsheb roj. Nws tuaj yeem ntsia tau rau hauv qhov chaw xws li txoj kev, cov tsev ua haujlwm, cov khw muag khoom, cov chaw nres tsheb pej xeem thiab cov chaw nres tsheb hauv tsev. , them ntau yam ntawm lub zog tshiab tsheb raws li qhov sib txawv voltage. Kev loj hlob sai sai tshiab lub zog tsheb lag luam tau nce qhov kev thov rau cov nqi them. Raws li cov ntaub ntawv ntawm Tuam Tshoj Automobile Association thiab Charging Alliance, los ntawm qhov kawg ntawm 2021, tus naj npawb ntawm cov tsheb tshiab lub zog hauv lub tebchaws yuav yog 7.84 lab, ib xyoos ib zaug nce ntawm 59.3 feem pua; tus naj npawb ntawm cov kev them nyiaj thoob ntiaj teb yuav ncav cuag 2.617 lab, ib xyoos ib zaug nce ntawm 55.7 feem pua. Kev loj hlob sai ntawm cov tsheb tshiab lub zog Kev ua lag luam tau nce qhov kev thov rau cov nqi them. Nyob rau hauv lub neej yav tom ntej, raws li kev nkag mus ntawm lub tsheb hluav taws xob txuas ntxiv mus ntxiv, kev lag luam kev thov rau cov khoom siv hluav taws xob yuav nthuav dav ntxiv.
High-voltage fast charging tau dhau los ua qhov kev daws teeb meem tseem ceeb rau cov teeb meem them nyiaj
Txhawm rau txhim kho cov kev paub dhau los ntawm cov neeg siv khoom, peb tuaj yeem txuas ntxiv txhim kho lub tsheb-rau-pile piv lossis txo lub sijhawm them nyiaj kom tau raws li cov kev xav tau ntawm cov neeg siv khoom kom them sai sai. Hais txog kev them nyiaj ceev, tam sim no muaj ob txoj hauv kev: ua kom lub zog them tam sim no thiab ua kom lub zog them nyiaj. Los ntawm qhov kev xav ntawm cov kev coj ua sib txawv, lub zog hluav taws xob ceev ceev tuaj yeem ua tiav lub zog them siab tshaj plaws hauv ntau qhov dav, thiab tuaj yeem ua tau zoo dua rau yav tom ntej kev xav tau ceev ceev:
1) Txoj kev siab tam sim no: qib qis ntawm kev nce qib thiab kev xav tau siab rau kev tswj xyuas thermal. Raws li Joule txoj cai (formula Q=I2Rt), qhov nce ntawm tam sim no yuav ua rau kom cov cua sov hauv cov txheej txheem them nyiaj ntau, uas yuav tsum tau ua kom muaj cua sov ntau. Kev siv cov hlua hlau tuab muaj qhov yuav tsum tau ua ntau dua rau cov thev naus laus zis thev naus laus zis, thiab tsuas tuaj yeem ua tiav lub zog them siab tshaj plaws ntawm 250kW ntawm 5 feem pua -27 feem pua SOC. High-efficiency charging tsis npog tag nrho cov txheej txheem. Tam sim no, cov tuam txhab tsheb hauv tsev tsis tau hloov kho qhov hloov pauv tseem ceeb hauv cov txheej txheem cua sov, thiab cov khoom siv hluav taws xob tam sim no feem ntau vam khom rau nws tus kheej, ua rau cov nqi nce qib siab.
2) High-voltage txoj kev: Nws yog ib hom uas nquag siv los ntawm cov tuam txhab tsheb tam sim no, uas tuaj yeem coj mus rau hauv tus account qhov zoo ntawm kev txo qis zog, txhim kho roj teeb lub neej, txo qhov hnyav, thiab txuag chaw. Tam sim no txwv los ntawm qhov muaj peev xwm tiv taus qhov muaj peev xwm ntawm silicon-based IGBT lub zog siv hluav taws xob, cov khoom siv ceev ceev uas siv los ntawm cov tuam txhab tsheb yog 400V high-voltage platform, uas yog, lub zog them ntawm 100kW tuaj yeem ua tiav nrog tam sim no ntawm 250A (100kW. ntawm lub zog tuaj yeem mus txog 100km rau 10 feeb). Txij li thaum Porsche tau tsim lub 800V high-voltage platform (ua tiav 300KW lub zog thiab txo cov hluav taws xob hluav taws xob hluav taws xob los ntawm ib nrab), cov tuam txhab tsheb loj tau pib tshawb fawb thiab teeb tsa ntawm 800V high-voltage platform txij thaum ntawd los. Piv nrog rau 400V platform, lub 800V voltage platform muaj ib tug me me kev khiav hauj lwm tam sim no, yog li txuag lub ntim ntawm cov hlua khi, txo lub sab hauv tsis kam ntawm lub Circuit Court, thiab txhim kho lub zog ceev thiab lub zog efficiency nyob rau hauv ib tug disguised daim ntawv.
