Njengoko izithuthi zombane ziqhubeka nokukhula kwihlabathi jikelele, ukusebenza kunye nokhuseleko lweenkqubo zebhetri zibe yinto ephambili kubakhiqizi. Enye yezona zinto zibaluleke kakhulu ngaphakathi kwe-EV ibhetri pack yi-busbar, edibanisa iiseli zebhetri kunye neemodyuli zokuqinisekisa ukudluliselwa kwangoku ngokufanelekileyo.
Kule nkqubo, umgangatho wokuwelda uchaphazela ngqo ukuxhathisa kombane, ukuveliswa kobushushu, kunye nokuthembeka{0}}kwexesha elide. Iindlela ze-welding zesiNtu zinokuzisa i-spatter, i-deformation, okanye i-joints engahambelani xa isebenza nge-copper encinci okanye i-aluminium. Ngenxa yoko, abaninzi abavelisi bajikaukusasaza iweldingnjengesisombululo esizinzile nesichanekileyo sokujoyina.
Eli nqaku licacisa indlela i-welding ye-diffusion esebenza ngayo kwiibhasi ze-EV zebhetri, zeziphi iiparamitha ezichaphazela umgangatho we-welding, kunye nendlela yokukhetha efanelekileyo.usasazo welding machineukwenzela imveliso.
Yintoni i-Diffusion Welding ye-EV Battery Busbars?
Umgaqo-siseko we-Diffusion Welding
Ukuwelda kokusasazwa yi-aokuqinileyo-inkqubo yewelding yelizwe. Esikhundleni sokunyibilika kwesinyithi, idibanisa izinto ngokufaka isiceloubushushu, uxinzelelo, kunye nexeshaukuze iiathom zisasazeke ngaphaya kojongano kwaye zenze ibhondi yesinyithi.
Ngexesha lenkqubo:
- Izinto eziphathekayo zixinzelelwe phantsi koxinzelelo olulawulwayo.
- Ummandla we-welding ushushu kwiqondo lokushisa elithile (ngokuqhelekileyo ngaphantsi kwendawo yokunyibilika).
- Ukusasazwa kweatom kwenzeka kumphezulu woqhagamshelwano.
- Iifom ezidibeneyo eziqinileyo ngaphandle kokunyibilika okanye izinto zokuzalisa.
Le ndlela ifanelekile ngokukodwaiibhasi zobhedu, iibhasi ze-aluminiyam, kunye ne-laminated flexible connectors, apho ukuhanjiswa kombane kunye nokunyaniseka kwesakhiwo kubaluleke kakhulu.
Kutheni i-EV yeBattery Busbars ifuna i-Diffusion Welding
Iibhasi zebhasi zifuna:
- Ukuxhatshazwa kombane okuphantsi
- Amandla omatshini aphezulu
- Ubuncinci be-thermal deformation
