Kungani I-Diffusion Welding Ingena Esikhundleni Se-Traditional Busbar Welding kuma-EV Battery Packs?

Njengoba imboni yezimoto ezintsha zamandla (NEV) iqhubekela phambili-ekukhiqizweni kwesilinganiso esikhulu kanye namazinga aphezulu okusebenza, isistimu yebhethri isiphenduke into enqumayo ekusebenzeni kwemoto, ukulawula izindleko, nokuphepha kokusebenza. Ukushisela iphakethe lebhethri lemoto yamandla entsha akusesona isinyathelo sokukhiqiza esivamile; manje sekuyinqubo ebalulekile ethinta ngokuqondile ibanga lokushayela, ukuzinza kokuphepha, nokuvumelana komkhiqizo.
Ngaphakathi kwesistimu yebhethri, amabhasi adlala indima ebalulekile ekudluliseni kwamanje, futhi ikhwalithi yoxhumo lwazo inquma ngokuqondile ukusebenza kukagesi wemoto. Njengoba umthamo webhethri uqhubeka nokukhula futhi ukuminyana kwamanje kukhuphuka, ukushiselwa kwebhasi kubhekene nezidingo ezidingeka kakhulu, okuhlanganisa:

• Higher conductivity kagesi
• Ukumelana nokuxhumeka okuphansi
• Ukuthembeka okukhulu{0}}kwesikhathi eside
• Ukusebenza kahle kokukhiqiza okuphezulu
• Ukulawulwa kwezindleko okungcono

Kodwa-ke, ubuchwepheshe bokujoyina obujwayelekile obufana ne-resistance welding, i-laser welding, kanye ne-ultrasonic welding buhlangabezana nemikhawulo njengoba okulindelwe kwezobuchwepheshe kuqhubeka nokuvela. Kulo mongo, i-diffusion welding, njengobuchwepheshe bokujoyina-okuqinile, ithola ukunakwa kubakhiqizi bamabhethri futhi kancane kancane ishintsha izindlela ezivamile kwezinye izinhlelo zokusebenza.
Lesi sihloko sihlola izimiso zobuchwepheshe, izinselele ezingokoqobo, kanye nentuthuko yemboni echaza ukuthi kungani i-diffusion welding iba ubuchwepheshe obuyinhloko ekukhiqizeni uxhumano lwebhethri.

Ezinhlelweni zamanje zokukhiqiza ze-NEV,ukumelana nokushisela, i-laser welding, kanye ne-ultrasonic weldingzihlale zisetshenziswa kabanziukuxhumana kwebhethri. Nakuba lezi zindlela ziye zasekela ukukhiqizwa iminyaka eminingi, ukulinganiselwa kwazo kuya ngokuya kubonakala njengoba amasistimu ebhethri eguqukela ekuphumeni kwamandla aphezulu kanye nokuminyana kwamandla okukhulu.
