-Yog tias koj xav them sai sai rau koj lub tsheb hluav taws xob, koj tsis tuaj yeem ua yuam kev nrog high-voltage, high-tam sim no technology rau them pawg

High tam sim no thiab high voltage technology

Raws li qhov sib txawv maj mam nce, muaj cov kev cov nyom xws li txo lub sij hawm them nqi thiab txo tus nqi ntawm cov tswv cuab, thiab thawj txoj haujlwm yog ua kom zoo dua qhov module loj kom ua tiav lub zog hloov khoom dua tshiab. Raws li lub zog ntawm lubpab pawgFeem ntau yog nyob ntawm lub hwj chim superposition ntawm lub them module, thiab yog txwv los ntawm cov khoom ntim, pem teb chaw thiab raug nqi, tsuas yog nce tus naj npawb ntawm modules tsis yog qhov zoo tshaj plaws tov. Yog li ntawd, yuav ua li cas nce lub zog ntawm ib qho module tsis ntxiv ntim ntxiv tau dhau los ua qhov teeb meem kev tshaj lij uasthem module manufacturersyuav tsum tau kov yeej sai sai.

DC cov khoom siv them nyiajua tau zoo heev ceev them peev xwm los ntawm high-tam sim no thiab high-voltage technology. Nrog rau qhov maj mam nce ntawm qhov hluav taws xob thiab lub zog, qhov no tso rau pem hauv ntej cov kev cai nruj dua rau kev ua haujlwm ruaj khov, ua kom muaj cua sov kom zoo thiab hloov pauv kev ua haujlwm ntawm cov khoom siv them nyiaj, uas tsis muaj qhov tsis ntseeg tau teeb tsa ntau dua kev cov nyom rau kev them nyiaj module manufacturers.

Nyob rau hauv lub ntsej muag ntawm kev ua lag luam thov rau high-power fast charging, charging module manufacturers yuav tsum tsis tu ncua innovate thiab txawj tej yam ntxiv thev naus laus zis hauv qab thiab tsim lawv tus kheej cov txheej txheem tseem ceeb. Qhov no yuav dhau los ua tus yuam sij rau kev sib tw ua lag luam yav tom ntej, tsuas yog los ntawm kev paub txog cov thev naus laus zis tseem ceeb, txhawm rau ua kom tsis muaj zog hauv kev sib tw ua lag luam hnyav.

1) High-tam sim no txoj kev: cov qib ntawm kev nce qib yog tsawg, thiab cov kev cai rau thermal tswj yog siab. Raws li Joule txoj cai lij choj (formula Q = I2Rt), qhov nce ntawm tam sim no yuav ua rau kom cov cua sov thaum lub sij hawm them nyiaj, uas muaj cov kev xav tau siab rau cov cua sov dissipation, xws li Tesla lub high-tam sim no them ceev daws teeb meem, uas nws V3 supercharging pawg muaj lub ncov ua hauj lwm tam sim no ntawm ntau tshaj 600A, uas yuav tsum tau ib tug thicker wiring harness, thiab nyob rau tib lub sij hawm tsuas yog cov kev xav tau ntawm cov hluav taws xob, nws muaj peev xwm ua tau raws li qhov xav tau ntawm cov khoom siv hluav taws xob ntau dua. 250kW hauv 5% -27% SOC, thiab kev them nyiaj tsis tau them tag nrho. Tam sim no, cov tuam txhab tsheb hauv tsev tsis tau ua qhov hloov pauv tseem ceeb hauv cov txheej txheem cua sov, thiabhigh-tam sim no them pawgvam khom rau tus kheej-tsim tshuab, 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, 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 hluav taws xob ntawm silicon-based IGBT cov khoom siv hluav taws xob, cov kev daws teeb meem ceev ceev uas feem ntau tau txais 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 lub zog tuaj yeem them rau 10min txog 100km). Txij li thaum pib ntawm Porsche's 800V high-voltage platform (ua tiav 300KW lub zog thiab halving lub high-voltage thaiv hlua), cov tuam txhab tsheb loj tau pib tshawb fawb thiab teeb tsa 800V high-voltage platform. Piv nrog rau 400V platform, lub 800V voltage platform muaj ib tug me me kev khiav hauj lwm tam sim no, uas txuag lub ntim ntawm cov hlua khi, txo lub internal kuj tsis tau ntawm lub Circuit Court, thiab txhim kho lub zog ceev thiab zog efficiency nyob rau hauv disguise.

Tam sim no, qhov hluav taws xob tas li tso zis hluav taws xob ntau ntawm lub ntsiab 40kW module hauv kev lag luam yog 300Vdc ~ 1000Vdc, uas yog sib xws nrog cov kev xav tau ntawm cov neeg caij tsheb tam sim no 400V platform, 750V tsheb npav thiab yav tom ntej 800V-1000V high-voltage platform tsheb; Cov zis hluav taws xob ntau ntawm 40kW module ntawm Infineon, Telai thiab Shenghong tuaj yeem ncav cuag 50Vdc ~ 1000Vdc, coj mus rau hauv tus account qhov kev xav tau ntawm cov tsheb tsawg-voltage. Nyob rau hauv cov nqe lus ntawm tag nrho cov ua hauj lwm efficiency ntawm lub module, lub 40kW high-efficiency modules ntawmBeiHai zogsiv SIC cov khoom siv hluav taws xob, thiab qhov ua tau zoo tshaj plaws tuaj yeem ncav cuag 97%, uas siab dua qhov nruab nrab ntawm kev lag luam.
