Kev Ntsuam Xyuas Ntawm Automotive BusBar PET Insulation Technology Trends hauv Kev Txhim Kho Lub Tsheb Tshiab Zog

Nrog rau kev loj hlob sai ntawm kev lag luam tshiab lub zog tsheb (NEV), kev tswj hluav taws xob thiab hluav taws xob sib txuas thev naus laus zis hauv - pawg tswj hwm hluav taws xob tau hloov pauv ntau. Capacitors thiab busbars, raws li cov khoom tseem ceeb hauv kev hloov pauv hluav taws xob thiab kev cia khoom, yog sib koom ua ke tsim "neural network" ntawm cov tshuab hluav taws xob. Hauv cov cheeb tsam tseem ceeb xws li cov khoom siv hluav taws xob hluav taws xob, ntawm -cov khoom siv hluav taws xob (OBCs), DC / DC converters, thiab roj teeb tswj tshuab (BMSs), kev sib koom ua ke ntawm DC zaj duab xis capacitors thiab tsheb busbars tau dhau los ua cov lus qhia tseem ceeb rau kev txhim kho voltage kam rau ua, suppressing electromagnetic cuam tshuam, thiab txhim kho kev ntseeg tau.

 

 

 

 

Nyob rau hauv lub tsheb tshiab zog, capacitors ua haujlwm xws li lim, decoupling, lub zog nqus, thiab resonance. Raws li kev ntsuas qhov ntsuas hluav taws xob thiab qhov ntsuas hluav taws xob, peb lub ntsiab ntawm cov khoom siv hluav taws xob tam sim no siv hauv cov tshuab tsheb: ceramic capacitors (MLCCs), txhuas electrolytic capacitors, thiab DC zaj duab xis capacitors.

 

Ceramic capacitor (MLCCs):Lawv muaj cov yam ntxwv zoo heev - zaus thiab haum rau cov teeb liab chains thiab qis -voltage systems.

Aluminium electrolytic capacitor:Lawv muaj lub peev xwm siab tab sis tsis tshua muaj hluav taws xob tsis zoo thiab feem ntau yog siv hauv cov ntawv siv hluav taws xob tsawg -voltage.

DC zaj duab xis capacitors:Lawv sib txuas cov hluav taws xob siab thiab kev ntseeg siab, ua rau lawv yog thawj hom capacitor rau DC -Txuas thiab lim circuits hauv lub tsheb tshiab.

 

Qhov siab - kub, siab -voltage, thiab siab - tam sim no muaj peev xwm ntawm zaj duab xis capacitors ua rau lawv cov khoom tseem ceeb hauv Onboard Control Boards (OBCs), DC / DC modules, thiab tsav inverters. Capacitor module kev koom ua ke feem ntau yuav tsum muaj co-tsim nrog lub capacitor busbar lossis DC capacitor busbar kom luv txoj hauv kev tam sim no, txo qhov sib npaug inductance (ESL), thiab txhim kho lub zog hloov pauv.

 

 

1. DC-Txuas txuas Capacitor thiab Busbar kev sib xyaw

Capacitor modules nyob rau hauv lub zog tshiab lub tsheb siab -voltage systems feem ntau ncaj qha mus rau lub busbar los ua ib tug capacitor laminating busbar qauv. Qhov kev tsim no txo ​​qis lub voj inductive nyob rau hauv siab -voltage thiab high- zaus zaus, txo qis zog poob.

 

Hauv hluav taws xob tsheb busbar tshuab, New Energy Vehicle Film Capacitor BusBar thiab busbar rau Power Capacitor yog cov kev daws teeb meem tseem ceeb. Lub busbar lub laminated tooj liab conductor qauv yog rwb thaiv tsev thiab tiv thaiv los ntawm Automotive BusBar PET rwb thaiv tsev zaj duab xis, kom ntseeg tau siab dielectric zog thiab mechanical yooj, raws li EV siab -voltage kev ruaj ntseg qauv.

 

2. Busbar Khoom thiab Plating Optimization

Txhawm rau txhim kho hluav taws xob conductivity thiab corrosion kuj, tin-plated tooj liab busbars rau EVs thiab tin- phaj busbars rau tsheb yog dav siv nyob rau hauv hluav taws xob tsav systems. Cov busbar automotive Cheebtsam ua kom tsis muaj kev tiv thaiv thiab thermal conductivity thaum lub sij hawm hloov hluav taws xob thiab hluav taws xob faib.

 

Tsis tas li ntawd, busbar rwb thaiv tsev tshuab ua tiav siab -voltage rwb thaiv tsev los ntawm PET, PI, los yog epoxy hmoov txheej. Ua ke nrog automotive fais fab connector qauv, nws enables system compactness thiab modularity. Rau EV busbars thiab EV roj teeb busbars, tswj cov rwb thaiv tsev thickness thiab dielectric zog yog qhov tseem ceeb tsim kev xav.

 

 

 

MLCC capacitors (multilayer ceramic capacitors) tseem irreplaceable nyob rau hauv automotive low-voltage and control systems. Lawv feem ntau yog siv hauv kev tswj hwm (ECUs), ADAS, radar, thiab hauv - tsheb infotainment systems. MLCC tus tsim lub davhlau ya nyob twg mos thiab peb -terminal qauv zoo txo ​​cov neeg kho tshuab kev ntxhov siab thiab cuam tshuam electromagnetic.

 

CeraLink capacitors, tsom rau siab- zaus SiC/GaN fais fab modules, ua lub luag haujlwm tseem ceeb hauv busbar-rau-busbar zaj duab xis capacitor modules vim lawv qhov qis ESL thiab cov yam ntxwv hloov pauv siab. Lawv feem ntau siv ua ke nrog cov qauv tsheb busbar los ua ib qho siab - zaus, ceev- teb tam sim no voj thiab txhim kho DC txuas ruaj khov.

 

 

Raws li lub zog tshiab lub tsheb platform architecture thiab lub zog module layout, automotive busbar txoj kev loj hlob tam sim no tsiv mus nyob rau hauv cov lus qhia nram qab no:

 

Automotive Ground Bus Bar (GBB):Muab txoj hauv kev thiab kev tiv thaiv kev cuam tshuam rau tag nrho lub tsheb thiab feem ntau yog siv hauv Onboard Battery Control (OBC) thiab Battery Management System (BMS) systems.

Tsheb roj teeb Bus Bar:Enables series thiab parallel kev twb kev txuas ntawm cov roj teeb packs thiab nqa high tam sim no.

Auto Bus Bar (General Motors Busbar):Npog them, hluav taws xob tsav, thiab hluav taws xob tswj, haum rau ntau lub tsheb platforms.

Capacitor Busbar & DC Capacitor Busbar:Co- ntim nrog capacitor modules txhawm rau txhim kho lub zog ncig.

 

Qhov kev sib faib segmentation no qhia txog qhov kev xav tau ntawm ob lub tsheb tshiab lub zog rau lub zog siab ceev thiab kev sib xyaw ua ke.

 

 

Nyob rau hauv lub zog tshiab lub tsheb hluav taws xob tshuab, kev sib koom tes tsim ntawm capacitors thiab busbar modules tsis yog tsuas yog hais txog conduction thiab lub zog cia, tab sis yog ib tug siab - zaus, siab -voltage, thiab low- impedance system kev koom tes.

 

Automotive BusBar PET rwb thaiv tsev tshuab ua kom muaj kev nyab xeeb siab -voltage.

Capacitor laminating bus bar muab qhov qis -ESL txoj kev tam sim no.

Tin-Plate Busbar Automotive ua tiav kev tiv thaiv corrosion thiab lub neej ntev.

Lub busbar hluav taws xob tsheb architecture txhawb zog hloov pauv sai hauv cov tshuab hluav taws xob ntse.

 

Yav tom ntej, BusBar automotive system yuav ua haujlwm nrog Capacitor Busbar los tsim kom muaj kev sib koom ua ke ntawm lub zog hluav taws xob uas txhawb nqa cov khoom siv hluav taws xob ntau dua (800V+) thiab siab dua - fais fab - ceev hluav taws xob tsav modules.

 

 

Nyob nruab nrab ntawm cov nthwv dej txuas ntxiv ntawm kev tsim kho tshiab hauv tsheb tshiab, kev hloov kho thev naus laus zis ntawm cov capacitors thiab busbars yog tsav kev txhim kho hauv tsheb hluav taws xob tswj architecture. Los ntawm kev ywj pheej thaum ntxov mus rau niaj hnub kev sib xyaw Tin-Plated Copper BusBar rau EV cov kev daws teeb meem, thiab los ntawm ib txwm muaj DC-Txuas cov capacitors mus rau New Energy Vehicle Film Capacitor BusBar qauv, txoj kev xa hluav taws xob luv luv, kev ua tau zoo yog nce, thiab kev ntseeg tau zoo dua.

 

Kev koom ua ke ntawm covTsheb BusBarthiab DC Capacitor BusBar sawv cev rau cov kev taw qhia tshiab rau cov ntse hluav taws xob tsheb hluav taws xob: sib dua, nyab xeeb, thiab ua haujlwm tau zoo dua.

 

Nyob rau hauv kev sib piv rau "siab dua voltage, ntau dua kev sib koom ua ke, thiab sib zog," kev sib koom ua ke optimization ntawm busbars thiab capacitors yuav txuas ntxiv muab kev ruaj khov thiab muaj zog txhawb nqa rau lub zog tshiab.
