Tus neeg uas ua ntawv zais hauv siab -Voltage Systems of New Energy Vehicles—Tsheb npav tab tom nkag mus rau qhov tsom teeb

Piv nrog rau cov tsheb roj av ib txwm muaj, cov tsheb tshiab lub zog tau dhau los hloov pauv hauv lawv cov qauv hluav taws xob tag nrho, ib qho tseem ceeb tshaj plaws yog qhov nce ntau hauv qhov system voltage thiab kev khiav hauj lwm tam sim no. Thaum kev lag luam tau tsom mus ntev rau cov khoom pom zoo xws li high-voltage connectors, high-voltage wiring harnesses, relays, and fuses to ensure high-voltage safe and energy transmission, the busbar-ib hom "tsis yog- qauv" lub luag hauj lwm rau penisable fais fab kev faib tawm{6 tivthaiv nyob rau hauv siab -voltage systems ntawm lub zog tshiab tsheb.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Tsheb npav tsis yog lub tswv yim tshiab. Txij li thaum lub advent ntawm high-voltage, siab- tam sim no fais fab engineering, busbars tau dav siv nyob rau hauv lub hwj chim, kev sib txuas lus, rail tsheb thauj mus los, thiab tub rog sectors. Nrog rau kev loj hlob sai ntawm lub zog tshiab tsheb thiab lub zog cia kev lag luam, daim ntawv teev cov nplai thiab cov txheej txheem nyuaj ntawm busbars hauv lub tsheb siab -voltage systems tau nce zuj zus, maj mam hloov lawv los ntawm "lub luag haujlwm txhawb" mus rau qhov tseem ceeb cuam tshuam rau kev ua haujlwm thiab kev ntseeg tau. Nyob rau hauv tag nrho cov siab -voltage system ntawm ib lub tsheb, lub busbar tsis tsuas yog ua tam sim no sau thiab tis functions tab sis kuj ncaj qha cuam tshuam rau lub cev kub nce, zog efficiency, electromagnetic compatibility, thiab spatial layout, ua nws lub luag hauj lwm nyob rau hauv lub busbar hluav taws xob lub tsheb architecture nce.

 

Los ntawm cov ntaub ntawv kev xav, busbars siv nyob rau hauv lub zog tshiab tsheb yog tsim los ntawm tooj liab thiab txhuas. tooj liab busbars, vim lawv zoo heev conductivity thiab stability, yog ntau lug siv nyob rau hauv siab -tam sim no, siab - kev cia siab rau scenarios. Raws li lawv cov qauv tsim thiab muaj peev xwm txo kev ntxhov siab, busbars tuaj yeem muab faib ua cov busbars nruj thiab hloov tau yooj yim busbars. Traditional rigid busbars muaj ib tug kuj yooj yim qauv thiab qis dua kev pib, feem ntau ua tau yooj yim conductive zog; thaum lub busbars hloov tau, los ntawm ntau- txheej laminated qauv, ua tau zoo dua kev ntxhov siab buffering thiab spatial adaptability, ua rau lawv zoo dua rau cov complex sib dhos ib puag ncig thiab siab - vibration tej yam kev mob, ua rau ib tug tsis tu ncua daim ntawv thov nqi nyob rau hauv automotive busbar tsim.

 

Nyob rau hauv lub siab -voltage systems ntawm lub zog tshiab tsheb, qhov zoo tshaj plaws ntawm busbars thiab laminated busbars yog qhov tseeb tshwj xeeb. Lawv cov qauv compact pab optimize qhov chaw layout ntawm cov roj teeb pob thiab hluav taws xob tswj systems; tsis tshua muaj impedance, tsis tshua muaj inductance, thiab zoo tshav kub dissipation kev ua tau zoo nyob rau hauv lub zuag qhia tag nrho system kub nce, zoo suppressing voltage spikes thiab txo cov kev cuam tshuam ntawm lub hwj chim khoom; cov txheej txheem ntau- txheej txheej tsis tsuas yog txhawb kev sib koom ua ke cov tswv yim thiab cov zis ntawm qhov sib txawv voltage tab sis kuj ua tau raws li EMI shielding cov cai.

 

Cov yam ntxwv no ua rau cov busbars maj mam hloov qee cov kev daws teeb meem hauv EV roj teeb busbar thiab tsheb fais fab busbar daim ntawv thov. Txawm li cas los xij, daim ntawv thov ntawm busbars tsis yog tsis muaj kev sib tw. Vim muaj qhov sib txawv tseem ceeb hauv qib voltage, lub zog ntom ntom, thiab qhov chaw teeb tsa thoob plaws cov qauv tsheb sib txawv thiab cov platforms, busbars nyuaj rau tus qauv, thiab feem ntau cov haujlwm xav tau kev tsim kho raws li cov qauv tsheb tag nrho. Tsim kom muaj kev cai busbar feem ntau xav tau kev nkag siab zoo thiab kev sib koom tes hauv kev sib koom tes, muab cov kev xav tau siab rau cov neeg tsim qauv hauv hluav taws xob, kev tsim qauv, thiab kev tsim khoom.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Siv lub zog roj teeb ua piv txwv, nws sab hauv siab -voltage kev sib txuas feem ntau yog muab faib ua ntau theem: cell-level, module-level, thiab pob-level. Hauv kev sib txuas ntawm tes - theem kev sib txuas, busbars feem ntau yog siv los txuas cov hlwb hauv cov kab sib txuas thiab sib txuas, feem ntau siv laser vuam, vuam tsis kam, lossis ultrasonic vuam, feem ntau siv cov hlau tsis sib xws los yog cov txhuas txhuas busbar. Nyob rau hauv module-theem thiab pob- theem kev sib txuas, hloov tau yooj yim thiab nruj busbars lossis siab-voltage cables yog siv ua ke, nyob ntawm qhov kev tsim qauv tsim, kom ua tau raws li cov txheej txheem sib dhos thiab kev saib xyuas. Qhov system no suav nrog kev siv tsheb hluav taws xob hluav taws xob busbar daim ntawv thov scenario.

 

Hauv cov tsav tsheb, cov tshuab hluav taws xob tswj, thiab ntawm - lub tshuab them nqi hluav taws xob, cov tsheb npav kuj ua lub luag haujlwm tseem ceeb hauv kev xa hluav taws xob. Txawm hais tias nws yog qhov zoo electrode faib los yog lub voj kev sib txuas, qhov kev ntseeg tau ntawm cov khoom zoo thiab qhov tsis zoo ntawm Busbars ncaj qha cuam tshuam rau lub sijhawm ntev - lub sijhawm ua haujlwm ruaj khov ntawm lub kaw lus. Piv nrog rau cov kab ib txwm siv, busbars muaj qhov zoo hauv kev txhim kho qhov tseeb, rov ua dua, thiab hloov pauv mus rau kev sib sau ua ke, maj mam dhau los ua ib qho tseem ceeb ntawm cov kev daws teeb meem tsheb busbar.

 

Los ntawm kev tsim kev xav, busbars lawv tus kheej tsis cia siab rau kev cuam tshuam cov txheej txheem tshiab, tab sis ua tiav kev ua tau zoo los ntawm kev sib koom ua ke ntawm cov txheej txheem paub tab. Cov txheej txheem ib txwm muaj xws li xaiv cov khoom siv, blanking, sib sau, vuam, xuas nrig ntaus, rwb thaiv tsev txheej, kho deg, thiab kuaj. Tus yuam sij rau kev xa khoom zoo, kev tswj hwm tus nqi, thiab kev ruaj ntseg zoo yog nyob rau hauv thaum ntxov -theem txheej txheem- theem kev tsim qauv tsim, tsis yog cov txheej txheem tsim khoom ntawm tus kheej. Qhov no tshwj xeeb tshaj yog tshwm sim nyob rau hauv qhov loj - nplai daim ntawv thov ntawm automotive roj teeb davhlau ya nyob twg busbars.

 

Thaum lub sijhawm tsim qauv tshwj xeeb, cov kws ua haujlwm feem ntau yuav tsum pib nrog tag nrho cov tsheb yuav tsum muaj zog, rhuav tshem cov kauj ruam -los ntawm - kauj ruam mus rau qhov voltage thiab tam sim no tsis ntawm lub roj teeb system, thiab raws li ua tiav rwb thaiv tsev tsim, creepage deb verification, thiab tam sim no - nqa peev xwm ntsuas. Thaum ua tau raws li qhov yuav tsum tau ua hauv hluav taws xob, yam xws li qhov kub thiab txias, kev siv hluav taws xob, kev siv hluav taws xob, thiab cov txheej txheem sib dhos yuav tsum raug txiav txim siab los txiav txim siab txog qhov kawg ntawm lub busbar tus qauv thiab cov txheej txheem tsis. Cov txheej txheem no yog qhov tseem ceeb rau kev ua tiav kev txhim khu kev qha hluav taws xob busbar.

 

Saib ua ntej, lub zog tshiab tsheb kev lag luam tau hloov zuj zus mus rau qhov siab dua cov platforms thiab lub zog ntau dua, nrog rau kev sib koom ua ke ntxiv. Qhov no ua rau qhov xav tau ntau dua ntawm cov busbars ntawm kev ntseeg siab, ua haujlwm ntev, thiab yoog mus rau kev sib dhos tsis siv neeg. Yuav ua li cas kom ua tiav tam sim no ntau dua - nqa peev xwm nyob rau hauv qhov chaw txwv thiab yuav ua li cas kom tswj tau qhov sib xws hauv qhov loj - nplai automated ntau lawm tau dhau los ua kev txhawj xeeb hauv kev lag luam. Nrog rau kev nthuav dav ntawm kev lag luam, cov kev daws teeb meem hauv nruab nrab ntawm kev sib koom tes tsim ntawmautomotive zog connectorsthiab busbars yuav dhau los ua ib qho kev taw qhia tseem ceeb rau theem tom ntej ntawm kev hloov pauv thev naus laus zis.

 

Zuag qhia tag nrho, raws li "pob ntseg" tivthaiv nyob rau hauv siab -voltage systems ntawm lub zog tshiab tsheb, busbars maj mam tsiv mus rau pem hauv ntej ntawm technology thiab tus nqi. Los ntawm kev xaiv cov khoom siv rau kev tsim qauv, los ntawm kev sib koom ua ke mus rau cov txheej txheem tsim khoom, lawv txoj haujlwm zoo hauv lub tsheb tau dhau los ua qhov tseem ceeb. Nws yog qhov pom tau tias nrog kev nthuav dav ntxiv ntawm kev lag luam hluav taws xob thiab lub zog cia, busbar-txog technologies thiab daim ntawv thov qauv yuav txuas ntxiv mus tob thiab tawg.
