800V Charging pawg "Charging Basics"
Kab lus no feem ntau tham txog qee qhov kev xav tau ua ntej rau 800Vthem pawg, ua ntej cia peb saib lub hauv paus ntsiab lus ntawm kev them nyiaj: Thaum lub ntsiab lus them nyiaj txuas nrog lub tsheb kawg, cov pawg them nyiaj yuav muab (1) qis-voltage auxiliary DC fais fab rau lub tsheb kawg kom qhib lub built-in BMS (roj teeb tswj qhov system) ntawm lub tsheb fais fab Tom qab ua kom tiav, (2) txuas lub tsheb kawg mus rau pawg kawg, sib pauv cov khoom siv hluav taws xob siab tshaj plaws ntawm cov khoom siv hluav taws xob. pawg kawg, tom qab ob tog sib phim kom raug, BMS (roj teeb tswj qhov system) ntawm lub tsheb kawg yuav xa cov ntaub ntawv xav tau rau lub zogev them chaw nres tsheb, thiab covhluav taws xob tsheb them pawgyuav kho nws tus kheej tso zis voltage thiab tam sim no raws li cov ntaub ntawv no, thiab officially pib them lub tsheb, uas yog lub hauv paus ntsiab lus ntawmthem kev txuas, thiab peb yuav tsum paub txog nws ua ntej.
800V them: "boost voltage lossis tam sim no"
Txoj kev xav, yog tias peb xav muab lub zog them nyiaj kom luv lub sijhawm them, feem ntau muaj ob txoj hauv kev: txawm tias koj nce lub roj teeb lossis nce qhov voltage; Raws li W = Pt, yog tias lub hwj chim them ob npaug, lub sij hawm them nyiaj yuav raug halved; Raws li P = UI, yog tias qhov hluav taws xob lossis qhov tam sim no yog ob npaug, lub zog them tuaj yeem raug muab faib ua ob npaug, uas tau hais ntau zaus thiab suav tias yog kev nkag siab zoo.
Yog tias qhov tam sim no loj dua, yuav muaj ob qhov teeb meem, qhov loj dua tam sim no, qhov loj dua thiab bulkier lub cable uas yuav tsum tau muaj tam sim no, uas yuav ua rau kom cov xaim txoj kab uas hla thiab qhov hnyav, nce tus nqi, thiab tsis yooj yim rau cov neeg ua haujlwm; Tsis tas li ntawd, raws li Q = I²Rt, yog tias qhov tam sim no siab dua, lub zog poob loj dua, thiab qhov poob tau tshwm sim hauv daim ntawv ntawm cov cua sov, uas tseem ua rau lub siab ntawm thermal tswj, yog li tsis muaj kev ntseeg tias nws tsis pom zoo kom nce lub zog them los ntawm kev nce tam sim no, txawm tias nws yog them los yog hauv lub tsheb tsav.
Piv nrog rau high-tam sim no them ceev,high-voltage ceev themua kom muaj cua sov tsawg dua thiab qis dua, thiab cov tuam txhab tsheb yuav luag tau siv txoj hauv kev ntawm kev nce voltage, nyob rau hauv cov ntaub ntawv ntawm high-voltage fast charging, theoretically lub sij hawm them tuaj yeem luv luv los ntawm 50%, thiab qhov nce ntawm qhov hluav taws xob kuj tuaj yeem yooj yim nce lub zog ntawm 120KW txog 480KW.
800V them: "Cov teebmeem thermal cuam tshuam rau qhov voltage thiab tam sim no"
Tab sis txawm hais tias nws yog nce qhov voltage los yog nce tam sim no, ua ntej ntawm tag nrho cov, nrog rau kev nce ntawm koj lub hwj chim them, koj cov cua sov yuav tshwm sim, tab sis lub thermal manifestation ntawm nce lub voltage thiab nce tam sim no txawv. Txawm li cas los xij, tus qub yog qhov zoo dua hauv kev sib piv.
Vim qhov tsis tshua muaj kev cuam tshuam los ntawm qhov tam sim no thaum dhau los ntawm tus neeg xyuas pib, txoj kev nce voltage txo qhov xav tau cable loj, thiab cov cua sov yuav tsum tau dissipated tsawg dua, thiab thaum lub sij hawm tam sim no nce, qhov nce ntawm qhov tam sim no-carrying cross-sectional cheeb tsam ua rau ib tug loj txheej txoj kab uas hla thiab ib tug loj cable hnyav, thiab lub tshav kub yuav maj mam nce nrog lub extension ntawm lub sij hawm them, uas yog ib tug ntau dua concee roj teeb.
800V them: "Qee qhov teeb meem tam sim nrog them pawg"
800V ceev them kuj tseem muaj qee qhov kev xav tau sib txawv ntawm pawg kawg:
Yog hais tias los ntawm lub cev ntawm qhov pom, nrog rau qhov nce ntawm qhov hluav taws xob, qhov tsim loj ntawm cov khoom siv sib txuas ua ke yuav nce ntxiv, piv txwv li, raws li cov pa phem ntawm IEC60664 yog 2 thiab qhov kev ncua deb ntawm cov khoom siv rwb thaiv tsev yog 1, qhov kev ncua deb ntawm cov cuab yeej hluav taws xob siab yuav tsum yog los ntawm 2 hli mus rau 4 hli, thiab tib qhov kev xav tau ntawm cov rwb thaiv tsev yuav tsum tau nce ntxiv, yuav luag ob npaug ntawm cov khoom siv rwb thaiv tsev. redesigned nyob rau hauv tus tsim piv nrog rau yav dhau los voltage system tsim, xws li connectors, tooj liab tuav, connectors, thiab lwm yam. Tsis tas li ntawd, qhov nce nyob rau hauv voltage kuj yuav ua rau kom siab dua cov kev xav tau rau arc extinguishing, thiab nws yog ib qho tsim nyog yuav tsum tau nce cov kev cai rau qee yam khoom siv xws li fuses, hloov lub thawv, connectors, thiab lwm yam., uas kuj muaj feem xyuam rau kev tsim lub tsheb, uas yuav tau hais hauv tsab xov xwm.
Lub high-voltage 800V charging system yuav tsum tau ntxiv ib qho kev ua kua dej txias sab nraud raws li tau hais los saum toj no, thiab cov cua txias ib txwm tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua txawm tias nws ua haujlwm lossis ua kom txias, thiab kev tswj xyuas thermalhluav taws xob tsheb them chaw nres tshebrab phom kab mus rau lub tsheb kawg kuj tseem siab dua ua ntej, thiab yuav ua li cas kom txo tau thiab tswj qhov kub ntawm qhov no ntawm qhov system los ntawm cov cuab yeej qib thiab qib system yog qhov taw tes kom txhim kho thiab daws tau los ntawm txhua lub tuam txhab yav tom ntej; Tsis tas li ntawd, ib feem ntawm cov cua sov no tsis yog tsuas yog cov cua sov coj los ntawm overcharging, tab sis kuj yog cov cua sov uas coj los ntawm cov khoom siv hluav taws xob ntau zaus, yog li yuav ua li cas saib xyuas lub sijhawm tiag tiag thiab ruaj khov, muaj txiaj ntsig zoo thiab muaj kev nyab xeeb kom tshem tawm cov cua sov yog qhov tseem ceeb heev, uas tsis yog tsuas yog kev puas tsuaj ntawm cov ntaub ntawv, tab sis kuj tseem muaj kev tshawb pom, xws li lub sijhawm tiag tiag thiab kev saib xyuas zoo ntawm kev them nyiaj kub.
Tam sim no, cov zis voltage ntawmDC charging pawgNyob rau hauv kev ua lag luam yog qhov pib 400V, uas tsis tuaj yeem them ncaj qha rau 800V lub zog hluav taws xob, yog li yuav tsum muaj kev txhawb nqa ntxiv DCDC cov khoom lag luam txhawm rau nce 400V voltage rau 800V, thiab tom qab ntawd them lub roj teeb, uas yuav tsum muaj lub zog ntau dua thiab hloov pauv ntau zaus, thiab cov module uas siv silicon carbide los hloov cov tsoos IGBT yog lub zog hluav taws xob tam sim no ntawm cov khoom siv hluav taws xob ntxiv, pawg thiab txo qhov poob, tab sis tus nqi kuj tseem ntau dua, thiab cov kev cai rau EMC kuj tseem siab dua.
Los sum nws. Yeej, qhov nce ntawm qhov hluav taws xob yuav tsum tau nce ntxiv ntawm qib system thiab qib ntaus ntawv, suav nrog kev tswj xyuas thermal, kev tiv thaiv kev them nyiaj, thiab lwm yam, thiab qib ntaus ntawv suav nrog kev txhim kho ntawm qee cov khoom siv hlau nplaum thiab cov khoom siv hluav taws xob.
