Flexible Copper Foil Connectors: Overcoming the Connection Challenges Of New Energy Vehicle Battery Packs With Flexible Design

As new energy vehicle power systems continue to evolve towards higher energy and power densities, the electrical interconnection structure within the battery pack is becoming a critical factor affecting system safety and durability. Tau ntsib nrog cov neeg kho tshuab kev vibrations, thermal cycling, thiab kev sib dhos tolerances, cov tsoos rigid conductors tau maj mam nthuav tawm lawv cov kev hloov tsis txaus. Cov kev sib txuas yooj yooj yim raws li ntau- txheej txheej tooj liab ntawv ci tau txais kev saib xyuas thoob plaws hauv lub zog roj teeb vim lawv qhov tshwj xeeb buffering thiab kev them nyiaj muaj peev xwm, dhau los ua ib qho tseem ceeb ntawm kev txhim kho rau cov neeg siv tshuab hloov tau yooj yim. Cov ntaub ntawv muaj xws li Flexible Copper BusBar thiab Copper Flexible BusBar structural designs.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Nyob rau hauv lub dynamic kev khiav hauj lwm ib puag ncig ntawm lub tsheb, kev co thiab poob siab yog tas li. Rigid connectors feem ntau ncaj qha hloov kev ntxhov siab mus rau lub xov tooj ntawm tes los yog cov pob qij txha, thiab ntev - lub sij hawm cyclic loading tuaj yeem ua rau kev nthuav tawm ntawm microcracks ntawm qhov kev sib cuag thiab drift hauv kev sib cuag. Nrog cov neeg hloov pauv hloov pauv, thaj chaw sib txuas tuaj yeem nqus qhov sib txawv ntawm qhov sib txawv thiab lub zog vibration los ntawm kev tswj tau deformation, yog li txo qhov qaug zog ntawm electrodes thiab busbar qauv. Engineering xyaum qhia tau hais tias xws li hloov pauv busbar connectors yog qhov tsim nyog rau kev tswj xyuas hluav taws xob txuas ntxiv thiab kev ncaj ncees nyob rau hauv cov xwm txheej siab cyclic loading.

 

Kev tswj cov cua kub kuj yog ib qho tseem ceeb ntawm kev tsim cov roj teeb hluav taws xob. Cov txheej txheem them thiab tso tawm ntawm lub roj teeb cuam tshuam nrog qhov kub thiab txias, thiab qhov sib txawv ntawm cov coefficients ntawm kev nthuav dav ntawm cov khoom sib txawv tuaj yeem ua rau muaj kev ntxhov siab ntxiv. Multilayer copper foil stacked structures muaj qhov yooj yim thiab tuaj yeem cuam tshuam qhov kev hloov pauv los ntawm qhov kub thiab txias, tiv thaiv thermal stress concentration ntawm weld lossis riveting interfaces. Cov yam ntxwv no ua rau Flexible BusBar Copper los ua kom pom kev ruaj ntseg thiab kev ntseeg siab hauv cov ntawv thov nrog kev caij tsheb kauj vab ntau zaus.

 

Los ntawm cov ntaub ntawv thiab cov txheej txheem kev xav, tooj liab, raws li cov hlau ua tau zoo, sib txuas cov ntim tsis tshua muaj zog thiab zoo ductility hauv kev sib txuas yooj yim. Los ntawm stacking ultra-thin tooj liab foils, dabtsi yog khoov nruj tuaj yeem txo qis thaum tuav tus ntoo khaub lig- ntu, ua tiav qhov sib npaug ntawm kev ua raws li kev ua raws cai thiab tam sim no - nqa lub peev xwm. Piv nrog rau cov khoom siv ib txwm muaj, Multilayer Copper Foils Flexible BusBars muaj qhov zoo ntawm ntau yam -axial displacement them nyiaj thiab tso tawm kev ntxhov siab, thiab tseem muaj kev ywj pheej ntau dua rau kev teeb tsa pob roj teeb.

 

Cov txheej txheem tsim khoom yog ib qho kev txiav txim siab hauv kev sib txuas ruaj khov ntawm cov ntawv ci tooj liab hloov tau. Cov kev daws teeb meem tam sim no feem ntau yog siv diffusion vuam lossis siab - kev ntseeg siab ntawm cov txheej txheem vuam los tsim cov kev sib txuas ntawm cov hlau nplaum ntawm cov txheej tooj liab, tsis txhob cuam tshuam kev cuam tshuam thiab cov teeb meem kev laus qhia los ntawm cov khoom siv. Lub siab - zoo metallurgical interface tsis tsuas yog txo kev tiv thaiv kev tiv thaiv tab sis kuj txhim kho kev qaug zog. Nyob rau hauv siab - zaus tam sim no thiab thermal cycling coupling tej yam kev mob, lub saj zawg zog tooj liab laminated busbar qauv tuaj yeem tswj tau ntev - lub sij hawm hluav taws xob stability.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Nyob rau theem kev siv lub cev, kev sib txuas tau yooj yim tooj liab tau siv dav hauv cov kab sib txuas thiab cov kab ntawm cov roj teeb, hluav taws xob txuas ntawm cov modules, thiab siab -voltage main circuit connection area. Tshwj xeeb tshaj yog nyob rau hauv siab -tam sim no tso zis scenarios, conductor kuj thiab kub nce tswj yog ncaj qha ntsig txog system efficiency thiab kev nyab xeeb margin. Lub qhov dej zoo-tsim tooj liab hloov tau yooj yim busbar tuaj yeem tsis tsuas yog ua tau raws li tam sim no - nqa cov kev xav tau tab sis kuj tseem txhim kho cov cua sov los ntawm thaj chaw loj dua. Thaum xaiv engineering, qhov hloov pauv hloov pauv tam sim no dhau los ua qhov taw qhia tseem ceeb rau kev ntsuas cov qauv tsim thiab thermal stability.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Dhau li ntawm cov roj teeb hluav taws xob, cov khoom siv hluav taws xob hloov tau yooj yim kuj tseem maj mam nthuav mus rau inverters, hluav taws xob tswj units, thiab siab -voltage power distribution modules. Nrog rau kev sib sib zog nqus ntawm lub platform-raws li thiab cov qauv tsim qauv, kev sib xyaw ua ke ntawm cov tsheb npav ntau ntau thiab cov qauv sib txuas tau yooj yim tau nce ntxiv kom ua tiav kev ua kom zoo tshaj plaws ntawm kev sib sau ua ke thiab kev vibration kev cia siab. Cov qauv no tshwj xeeb tshaj yog pom nyob rau hauv kev sib xyaw ua ke ntawm tsheb tooj liab tsheb npav tsim.

 

Nto engineering thev naus laus zis kuj tseem muaj feem cuam tshuam rau lub sijhawm ntev - kev pabcuam kev ua haujlwm ntawm cov khoom siv tooj liab hloov tau yooj yim. Los ntawm kev qhia tin plating lossis lwm cov txheej tiv thaiv, oxidation thiab corrosion kuj tuaj yeem txhim kho tau zoo, thaum sib dhos thiab kev sib cuag cov yam ntxwv kuj tseem txhim kho. Cov ntaub ntawv ib txwm, xws li tin-plated tooj liab npav npav thiab tinned tooj liab npav npav, yog qhov zoo dua ntawm kev tswj xyuas kev ruaj ntseg thiab txo cov kev pheej hmoo ntawm kev saib xyuas nyob rau hauv high humidity thiab complex climatic tej yam kev mob.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Tsav los ntawm kev hloov kho thev naus laus zis txuas ntxiv hauv kev lag luam, kev sib txuas ntawm tooj liab hloov pauv hloov mus rau qhov siab dua tam sim no - nqa peev xwm, lub neej qaug zog zoo dua, thiab kev sib koom ua ke ntau dua. Kev taw qhia txog cov khoom siv tshiab, cov txheej txheem lamination tsis siv neeg, thiab cov thev naus laus zis sim online yuav txhim kho qhov kev ntseeg siab ntawm engineering thiab kev sib xws ntawm tooj liab busbars hauv lub zog tshiab. Lub caij no, ntau-txheej tooj liab foil hloov tau yooj yim tsheb npav tsim lub tswv yim, uas sib npaug lub teeb yuag tsim nrog kev ua haujlwm siab, tau dhau los ua ib qho tseem ceeb rau kev tshawb nrhiav nyob rau tom ntej - tiam siab -voltage interconnect structures.

 

 

Flexible copper foil connectors yog tsis yooj yim conductive jumpers. Nyob rau hauv niaj hnub EV roj teeb tshuab, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob faib hluav taws xob, lawv ua haujlwm raws li ob qho tib si hluav taws xob conductors thiab cov khoom siv nyiaj txiag.

 

Los ntawm kev sib txuas ntawm laminated copper foil siv, diffusion vuam tshuab, thiab hloov tau yooj yim conductive txoj kev tsim, cov connectors no pab txo thermal qaug zog, kev co puas tsuaj, thiab installation kev nyuaj siab nyob rau hauv siab - tam sim no hluav taws xob systems.

 

Rau cov tshuab hluav taws xob raug rov ua dua thermal cycling thiab mechanical zog, hloov tau yooj yim laminated tooj liab connectors muab ib tug ruaj khov ntev dua -lub sij hawm conductive tov tshaj rigid busbar lug.

 

 

Tsom ntsoov rau cov kev xav tau xws li tsheb tshiab, hluav taws xob hluav taws xob, thiab lub zog cia, peb txuas ntxiv txhim kho kev tsim kho ntawm peb cov Laminated Copper Flexible Connectors thiab Copper Flexible BusBar series, encompassing multi- specification Flexible BusBars, siab -kev cia siabFlexible Copper BusBars, thiab txhim kho kev tiv thaiv Tin Plated Copper BusBar daws teeb meem. Los ntawm kev sib koom ua ke ntawm kev tswj cov khoom siv, kev sib txuas ntawm metallurgical, thiab tam sim no - nqa lub peev xwm tsim, peb muab kev sib txuas ruaj khov thiab txhim khu kev ntseeg tau yooj yim rau siab - kev co, siab - tam sim no, thiab siab -thermal- ib puag ncig kev caij tsheb kauj vab. Yog xav paub ntxiv txog cov txheej txheem lossis cov lus qhia xaiv, peb tuaj yeem muab cov phiaj xwm ntsuas thiab tsim kev sib txuam raws li kev thov tshwj xeeb.
