Kev soj ntsuam ntawm daim ntawv thov scenarios thiab kev tsim kho thev naus laus zis ntawm EV Bus Bars

EV Bus Bars (tseem hu ua "copper bars" lossis "busbars") yog cov tseem ceeb ntawm cov khoom siv hluav taws xob ntawm high -voltage hluav taws xob systems, ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv kev faib hluav taws xob thiab kev sib kis. Lawv tau siv dav hauv cov xwm txheej tseem ceeb xws li cov roj teeb pob, hluav taws xob tsav tsheb, thiab lub tshuab them nyiaj. Nws qhov kev ua tau zoo cuam tshuam ncaj qha rau kev ruaj ntseg, kev siv hluav taws xob, thiab kev nyab xeeb ntawm lub siab -voltage system ntawm lub zog tshiab. Kab lus no yuav muab faib ua tsib ntu rau kev txheeb xyuas raws qhov ntev xws li lub luag haujlwm tseem ceeb, cov xwm txheej ntawm daim ntawv thov, thiab kev txhim kho yav tom ntej, muab kev siv rau cov kws tshaj lij kev lag luam.

Lub luag haujlwm tseem ceeb ntawm Automotive BusBar PET Rwb thaiv tsev yog ua kom tau txais kev sib kis tau zoo ntawm cov hluav taws xob siab thiab siab tam sim no. Nws feem ntau yog siv cov khoom siv hluav taws xob siab los yog txhuas ua cov txheej txheem thiab ua tiav rau hauv cov qauv siv hluav taws xob, uas tsim nyog rau kev ua haujlwm ntawm cov tsheb tshiab lub zog hluav taws xob (feem ntau yog 300V-800V) thiab siab tam sim no (txog 600A lossis ntau dua). Piv nrog rau cov kev daws teeb meem kev sib txuas ib txwm siv, Lub Tsheb Roj Teeb Tsav Tsheb Bar muaj qhov zoo ntawm qhov chaw siv, kev sib kis tau zoo, thiab kev ua haujlwm tau zoo. Nyob rau hauv cov nqe lus ntawm kev siv qhov chaw, lub tiaj tus qauv tuaj yeem txo qhov ntim ntawm cov xov hlau, ua kom zoo dua rau qhov chaw tsim khoom hauv lub zog tshiab, thiab txuag tau qhov chaw teeb tsa; Nyob rau hauv cov nqe lus ntawm kis tau tus mob efficiency, lub conductivity poob ntawm Auto Bus Bar yog ho qis dua cov tsoos cables, nrog ib tug tooj liab bar resistivity ntawm txog 0.017 Ω· mm ² / m. Piv nrog rau cov cables nrog tib qhov chaw hla ntu, qhov poob tuaj yeem raug txo los ntawm 15% -20%, uas pab txhim kho kev siv hluav taws xob zoo ntawm tag nrho lub tsheb; Hais txog kev ntseeg siab, cov qauv kev sib koom ua ke tuaj yeem ua kom tsis txhob muaj kev pheej hmoo xws li cov khoom sib txuas xoob, thaum ua tau raws li cov qauv kev tiv thaiv nruj xws li IP67, thiab hloov mus rau qhov chaw ua haujlwm nyuaj hauv tsheb.

Ib qho yog qhov kev sib koom ua ke sab hauv ntawm lub hwj chim roj teeb pob. Hauv qhov xwm txheej no, Automotive Power Connectors feem ntau ua haujlwm txuas thiab xa hluav taws xob ntawm lub roj teeb module thiab Battery Management System (BMS), uas yog qhov txuas tseem ceeb kom ntseeg tau tias cov khoom siv hluav taws xob ruaj khov los ntawm cov roj teeb pob. Tam sim no lub ntsiab voltage platforms feem ntau muab faib ua ob pawg: 400V thiab 800V, uas yog haum rau cov kev xav tau ntawm lub zog tshiab tsheb nrog txawv zog theem. Xav tias lub roj teeb pob yuav tsum tau tiv thaiv kev ua haujlwm nyuaj hauv lub tsheb ib puag ncig ntev, Busbar Automotive yuav tsum muaj qhov kub thiab txias ua haujlwm zoo thiab kev co ua haujlwm. Qhov kev khiav hauj lwm kub kub yuav tsum tau npog -40℃~ 125 degree, thiab tib lub sijhawm, nws yuav tsum tau ua kom tau raws li qhov yuav tsum tau muaj ntawm cov txheej txheem kev ntsuas qhov cuam tshuam los xyuas kom muaj kev sib txuas ruaj khov thiab hluav taws xob ua haujlwm txawm tias nyob rau hauv lub ntsej muag ntawm pob, vibrations, thiab lwm yam xwm txheej thaum tsav tsheb. Raws li kev tsim kho thev naus laus zis, los ntawm kev sib xyaw tsim ntawm busbar, tus naj npawb ntawm cov khoom siv sab hauv ntawm lub pob roj teeb tuaj yeem txo qis, cov txheej txheem sib dhos tuaj yeem yooj yim, thiab kev sib xyaw ua haujlwm ntawm cov roj teeb pob tuaj yeem txhim kho.

Qhov thib ob, qhov siab -voltage interconnection scenario ntawm lub tshuab hluav taws xob tsav. Raws li lub hauv paus ntawm lub zog tso zis ntawm lub zog tshiab tsheb, lub zog tsav hluav taws xob yog lub luag haujlwm tseem ceeb rau kev ua haujlwm siab -voltage interconnection ntawm lub inverter thiab tsav lub cev muaj zog. Nyob rau hauv qhov xwm txheej no, lub ncov tam sim no feem ntau tuaj yeem ncav cuag tshaj 500A, uas tso siab dua cov kev xav tau ntawm kev sib kis tau zoo thiab cov yam ntxwv poob qis ntawm busbar. Txhawm rau txo qis kev hloov pauv thiab txhim kho kev ua haujlwm ntawm lub zog tsav hluav taws xob, Capacitor Busbar yuav tsum tau txais kev tsim qauv qis, feem ntau xav tau tus nqi inductance qis dua 10nH / cm. Nyob rau tib lub sijhawm, txhawm rau tiv thaiv oxidation ntawm tus neeg xyuas pib nto thiab xyuas kom ntev - lub sij hawm ruaj khov conductivity, qhov saum npoo ntawm busbar feem ntau yog kho nrog tin plating lossis nyiaj plating. Tsis tas li ntawd, nrog rau kev txhim kho cov tshuab hluav taws xob sib xyaw ua ke, qee qhov kev daws teeb meem tuaj yeem txhim kho cov cua sov kom zoo dua los ntawm kev sib xyaw cov dej txias thiab lwm cov qauv tsim rau hauv cov qauv busbar, ntxiv rau kev ua haujlwm ruaj khov ntawm busbar nyob rau hauv cov xwm txheej tam sim no.

Thirdly, qhov scenario ntawm ceev them pawg fais fab faib. Nyob rau hauv DC fast charging pawg system, DC Capacitor Busbar feem ntau yog siv rau kev faib khoom thiab xa tawm ntawm high-voltage hluav taws xob hluav taws xob, uas yuav tsum tau hloov mus rau siab - lub zog them ceev ceev. Nws feem ntau yuav tsum tau nqa lub zog xa hluav taws xob ua haujlwm ntawm 480V / 250kW lossis ntau dua, thiab hauv qee qhov xwm txheej, tam sim no tuaj yeem ncav cuag 600A, thiab lub sijhawm yuav tsum tau ua kom tau raws li qhov xav tau ceev ceev ntawm ntau tshaj 10 feeb. Raws li cov yam ntxwv ua haujlwm ntawm cov hluav taws xob siab thiab siab tam sim no, cov txheej txheem rwb thaiv tsev ntawm Busbar Rwb thaiv tsev yuav tsum muaj qhov ua tau zoo ntawm kev ua haujlwm siab, feem ntau yuav tsum muaj qhov hluav taws xob tiv taus ntau dua 3000V thiab ua raws li cov qauv kev lag luam thiab cov kev qhia tshwj xeeb. Txhawm rau daws qhov teeb meem ntawm qhov kub thiab txias thaum lub sij hawm siab - fais fab kis tau tus mob, kua{12}} txias busbar tshuab tau maj mam siv. Los ntawm cov kua txias, kev ua haujlwm kub ntawm lub busbar tuaj yeem tswj tau zoo hauv 15 degree, muab kev lees paub rau kev ua haujlwm zoo thiab kev nyab xeeb ntawm kev them nyiaj ceev.

Nrog kev txhim kho txuas ntxiv ntawm kev lag luam tshiab lub zog tsheb mus rau siab -voltage, lub teeb yuag, thiab cov lus qhia ntse,EV Bus Barsthev naus laus zis tab tom ntsib cov teeb meem tshiab thiab txoj hauv kev txhim kho. Nyob rau hauv lub neej yav tom ntej, yuav muaj peb txoj kev loj hlob tseem ceeb: ua ntej, qhov kev thov nce qib kev ua tau zoo coj los ntawm qhov nrov ntawm 800V siab-voltage platforms. Raws li cov qauv ntawm high voltage, BusBar Tsheb yuav tsum muaj zog dua rwb thaiv tsev. Los ntawm kev ua kom zoo dua cov ntaub ntawv rwb thaiv tsev, ua kom cov rwb thaiv tsev tiv thaiv cov khaubncaws sab nraud povtseg, thiab lwm txoj hauv kev, kev nyab xeeb kev nyab xeeb xws li siab -voltage breakdown yuav raug zam kom ua haujlwm ruaj khov ntawm high-voltage systems. Qhov thib ob yog kev sib koom ua ke ntawm kev saib xyuas kev txawj ntse. Los ntawm kev sib koom ua ke ntawm qhov kub thiab txias, tam sim no, thiab lwm yam sensors ntawm New Energy Vehicle Film Capacitor BusBar, tiag tiag- lub sijhawm saib xyuas kev ua haujlwm ntawm lub busbar tuaj yeem ua tiav, ceeb toom raws sijhawm ntawm cov xwm txheej txawv txav xws li overheating thiab overcurrent, ntxiv kev txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm siab -voltage system ua haujlwm.

Kev nug tsis yog ib qho kev cog lus cog lus rau kev txiav txim. Peb zoo siab tos txais txhua yam kev nug txog peb cov khoom, nqi, specifications, thiab cov kev pabcuam cuam tshuam, thiab yuav teb rau koj nrog cov ntaub ntawv tshaj lij thiab cov ncauj lus kom ntxaws raws sijhawm.
