Ga shadawn: EV Batteries ni a matu Flexible Copper-Aluminum Busbar ni hte rau shang lawm na
(Ju aiHAIFEI garan ginhka ai lam ni hpe galaw ai.)
Hpa Majaw Ndai Matsun ni:
Electric mawdaw (EVs) ni gaw battery cell ni a lapran hta wan n-gun kaba ni hpe shim lum ai hte hkrak hkrak htawt sit ra ai.}.N-gun n rawng ai magri-aluminum bu hpun palawng nindai bungli hpe hparan ai "nerves" ni a is. Raitim, manghkang langai mi nga ai:
🔥 Copper + Aluminium + Melt Welding=DISASTER!
- Ndai metal ni hpe shingdaw nna galaw ai gaw .kaji ai intermetallic compound ni( CuAl) zawn)
- Ndai compound ni gaw .n-gun rawng ai npu hta n-gun rawng ai, grai katsi ai, battery hkrat sum ai lam ni hpe byin shangun ai.
Diffusion Welding gaw dai hpe hkam la u:
HIFEI garan ai jak nishachyaw aisolid-state, atom-level bondsmelting n nga ai. Ndai hku galaw ai:
Lahkam mi hpang langai galaw ai lam
{0}} Ntsa lam hpe tau hkrau tsun da ai:
- Copper hte aluminum strips ni gaw .laser hte jasan jaseng aioxides. hpe yeng seng kau na matu re.
- Surface ni gaw atom hku nna n-gun n rawng mat ai ( "metal mirror" hpe myit yu u){0}}}.

- Strip ni hpe .HAIFEI jak.
{0}} Hydraulic rasn-gun kaba hpe jai lang na (e{0}g{1}, 50 MPa) → n-gup magap ni hpe hkum tsup ai hku matut mahkai ai lam. de bang na.

Mahtai:
A n-gun n rawng ai, galai shai mai ai jointdai hte:
✅ Hkum tsup ai hku galaw lu ai atsam(san seng ai magri zawn){0}}.
✅ Fatigue ninghkap ai lam(hpring tsup ai 10,000+ EV vibrations){2}}.
✅ Zero katsi ai majaw hkra machyi ai shara(n-gun kya ai shara n nga ai){0}}.
Hpa majaw Ndai gaw EVs ni a matu Rawt Malan ai lam re
| Conventional Welding | HIFEI garan ai Welding |
|---|---|
| ❌ Joints ni gaw hka leng ni hta grai katsi ai | ✅ Carri{0}} ampshotspot n lawm ai |
| ❌ 2–3 ning laman hta hkrat sum ai | ✅ Asak hkrung ai>15 ning |
| ❌ Rigid → bent galaw ai shaloi n-gun n rawng ai | ✅ Flex ni gaw belt zawn re ai( battery n-gun rawng ai) |
Industry hta tengman ai Impact
Tesla/Gigafactories: 1990 ning hta diffusion hte htu da ai busbar ni hpe lang u.Battery Pack Modules.
CATL/BYD: Ndai hpe deploy galaw na matucell-to-pack (CTP) htingnu gawgap ai lam ni.
HAIFEI Machine ni: Masha law law hpe galaw lu hkra galaw na>500,000 busbar/shata .dai hte<0.1% defect rate.
Nutshell hta:
Na a EV a battery pack hta copper-aluminum busbar joint –n mu lu ai, galai shai mai ai, ultra-kam hpa mai ai– gaw .hpring tsup aiga shadawn hku nna diffusion welding welding a. "N mai byin ai" arung arai manghkang hpe hparan ya nna, mai byin ai, hpa majaw nga yang:
- Hka lim ai lam n byin ai(so solid-state nga ai)..
- HAIFEI jak nin-gun n-gun/ katsi ai hte micron-level hkrak hkrak rai nga ai..
- atomic diffusfu gumhprawn-gun grau ja ai n-gun hpe hpri ni hkum nan. hta n-ga.
Rivet n nga ai, bolt n nga ai, n-gun n rawng ai – n-gun n rawng ai – hpaji masa hku sha green energy bungli galaw ai.}. 🔋⚡
