Lub EV Busbars Kev Lag Luam Ushers nyob rau hauv Ib Lub Sijhawm Tshiab Ntawm Dual Drive Of Technology Iteration Thiab Kev Lag Luam Expansion

Raws li lub ntiaj teb hluav taws xob tsheb (EV) kev lag luam nkag mus rau theem ntawm kev loj hlob - nplai, EV busbar, raws li lub hauv paus tseem ceeb ntawm siab -voltage fais fab kis tau tus mob, tau ntsib dual tawg ntawm thev naus laus zis innovation thiab kev lag luam xav tau. Cov ntaub ntawv kev lag luam qhia tau hais tias lub ntiaj teb EV busbar kev lag luam loj tau mus txog US $ 1.686 nphom hauv 2024, thiab xav tias yuav tshaj US $ 5.4 nphom los ntawm 2030, nrog rau kev loj hlob txhua xyoo (CAGR) ntawm 21.6%. Tom qab qhov kev loj hlob no yog qhov kev xav tau ceev ceev rau lub tsheb tshiab lub zog kom muaj lub siab - kev nyab xeeb thiab siab - kev ntseeg siab ntawm lub zog xa hluav taws xob, nrog rau kev ua tsis tu ncua ntawm cov ntaub ntawv tshawb fawb thiab kev tsim khoom.

 

 

 

Lub luag haujlwm tseem ceeb ntawm Automotive BusBar yog kom ua tiav siab - tam sim no thiab kev sib kis tau zoo ntawm cov roj teeb pob, lub cev muaj zog, thiab lub tshuab them nyiaj. Nws qhov kev ua tau zoo cuam tshuam ncaj qha rau lub tsheb endurance, kev them nqi, thiab kev nyab xeeb. Tam sim no, kev lag luam tab tom ua cov txheej txheem thev naus laus zis hauv cov lus qhia hauv qab no:

 

1. Sib npaug ntawm cov khoom siv hnyav thiab kev ua haujlwm siab
Cov tsoos tooj liab busbars tseem yog cov kev xaiv tseem ceeb nrog cov thermal conductivity ntawm 401W / mK thiab thermal expansion coefficient ntawm 16.5 ppm / K. Txawm li cas los xij, nyob rau hauv kev teb rau cov qauv ntawm lub teeb yuag, kev ua lag luam feem ntawm aluminium busbars (qhov ceev tsuas yog 1/3 ntawm tooj liab) tau maj mam nce. Los ntawm nto nickel plating los yog composite plating tshuab, oxidation tsis kam ntawm txhuas busbars tau mus txog ntawm EV Bus Bars, thaum tus nqi tau txo los ntawm ntau tshaj 30%. Qee lub tuam txhab tab tom tshawb nrhiav tooj liab-aluminium composite busbars, sib txuas qhov zoo ntawm ob qho tib si, kom ua tiav 20% nce ntawm qhov ceev tam sim no hauv siab -voltage fast charging scenarios.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2. Kev sib koom ua ke thiab kev tsim qauv
Lub cim tshiab ntawm EV roj teeb busbars integrates functional Cheebtsam xws li sensors thiab fuses rau hauv lub insulating matrix kom ua tau ib tug tshiab architecture ntawm "busbar li system". Piv txwv li, lub tsheb npav tshiab sib xyaw ua ke tuaj yeem muaj qhov tsim ua -nyob rau hauv qhov ntsuas kub ntsuas los muab qhov tseeb - lub sij hawm tawm tswv yim ntawm lub busbar kub, thiab dynamically kho lub charger thiab tawm tswv yim ua ke nrog BMS (roj teeb tswj system), txo qhov kev pheej hmoo ntawm thermal runaway los ntawm 50%. Tsis tas li ntawd, tus qauv tsim qauv ua rau lub busbar hloov mus rau cov qauv roj teeb sib txawv, thiab cov khoom siv tau nce ntau dua 30%.

 

3. High-voltage fast charging technology adaptation
Qhov nrov ntawm 800V siab -voltage platforms tau tsav lub evolution ntawm busbar hluav taws xob tsheb mus rau ntau dua tam sim no ceev. Cov ntaub ntawv qhia tau hais tias cov busbars uas txhawb nqa 350kW ceev them yuav tsum tau tiv thaiv tam sim no ntau tshaj 500A, thiab cov qauv tsim tsis tuaj yeem ua tau raws li qhov xav tau. Kev lag luam tau txo qhov kev tiv thaiv qis dua 1mΩ los ntawm kev ua kom zoo ntawm tus neeg xyuas pib hla -sectional cheeb tsam, siv ntau- ncej pob ntseg qauv thiab laser vuam txheej txheem, thiab qhia cov ntaub ntawv tshiab insulating xws li boron nitride kom muaj zog tiv taus rau 1500V.

 

Kev nce nrawm hauv ntiaj teb EV kev muag khoom tau txhaj lub zog muaj zog mus rau hauv lub lag luam Bus Bar Connector. Nyob rau hauv thawj ib nrab ntawm 2024, EV muag khoom nyob rau hauv Tuam Tshoj, Teb chaws Europe, thiab North America tau nce 32% xyoo-ntawm- xyoo, ua rau muaj kev xav tau ntawm busbar. Cov subdivisions muaj cov yam ntxwv hauv qab no:

 

1. Lub zog hluav taws xob sib txuas ua lag luam loj tshaj plaws
Qhov nrov ntawm cylindrical roj teeb packs tau tsav innovation nyob rau hauv busbar tsim. Piv txwv li, lub roj teeb Bus Bar qauv nrog rau sab saum toj bipolar kev twb kev txuas tuaj yeem zam qhov kev cuam tshuam ntawm cov cua txias, thiab cov neeg xyuas pib thiab cov yeeb yaj kiab insulating yog kev sib koom ua ke los ntawm cov txheej txheem lamination, uas ua rau kom lub zog ceev ntawm lub roj teeb pob los ntawm 8%. Nws yog kwv yees tias los ntawm 2030, lub busbar rau lub hwj chim roj teeb yuav nyob 69% ntawm lub ntiaj teb no ua lag luam feem.

 

2. Qhov kev thov rau lub zog cia thiab cov chaw them nqi tau tawg ib txhij
Nrog rau kev siv ntawm V2G (tsheb mus rau daim phiaj) thev naus laus zis, qhov kev thov rau IGBT Bus Bars hauv lub zog khaws cia tau nce. Piv txwv li, DC busbar ntawm lub zog loj cia chaw nres tsheb fais fab yuav tsum tiv taus qhov tam sim no ntau tshaj 2000A. Kev lag luam tau nce qhov kev cia siab rau qhov system mus rau 99.9% los ntawm kev tsim cov segmented thiab redundant qauv. Tsis tas li ntawd, qhov siab -voltage DC busbar kev ua lag luam rau supercharging pawg muaj kev loj hlob txhua xyoo ntawm 35%, dhau los ua tus ncej tshiab hauv kev lag luam.

 

3. Kev lag luam hauv cheeb tsam sib txawv zuj zus
Asia- cheeb tsam Pacific, nrog rau nws txoj kev lag luam tshiab kev lag luam, muaj 69% ntawm lub ntiaj teb Automotive Power Connectors kev lag luam. Tuam Tshoj cov tuam txhab muaj txiaj ntsig zoo hauv kev ua lag luam tooj liab busbar, thaum cov tuam txhab Japanese thiab Kauslim yog cov thawj coj hauv aluminium busbar lightweighting technology. Kev ua lag luam nyob sab Europe tsom rau siab -tus nqi- ntxiv cov busbars sib xyaw ua ke, thiab tus nqi ntawm ib pawg ntawm cov khoom yog 40% siab dua li cov tsoos busbars.

 

Txawm hais tias muaj kev cia siab zoo, covEV busbarkev lag luam tseem ntsib ntau yam kev nyuaj:
Supply Chain Fluctuation:Tus nqi ntawm cov khoom siv raw xws li tooj liab thiab txhuas tau cuam tshuam loj heev los ntawm cov xwm txheej thoob ntiaj teb. Tus nqi tooj liab hloov pauv hauv 2024 yuav ncav cuag 25%. Cov tuam txhab lag luam yuav tsum kaw cov nqi los ntawm kev sib cog lus ntev -.

Standard Upgrade:Tuam Tshoj qhov tseeb GB 38031-2020 tus qauv ntxiv dag zog rau kev tiv thaiv kev tiv thaiv ntau dhau ntawm cov roj teeb, thiab cov busbars yuav tsum tau nruab nrog cov qauv ntsuas hluav taws xob ntau dua.

Cov txheej txheem ntau ntxiv:Kev tsim khoom ntawm kev sib koom ua ke Auto Bus Bars koom nrog ntau yam txheej txheem xws li laser vuam thiab kev txhaj tshuaj molding, uas ua rau nws nyuaj rau tswj tus nqi tawm los. Cov tuam txhab ua lag luam tau txo qis tus nqi tsis zoo rau tsawg dua 1% los ntawm cov chaw tsim khoom digital.
