Tin Coated Copper Busbar Prodution Process:
1. Substrate pretreatment
- Unwinding and annealing: copper wire is stretched by wire drawing machine and then annealed, controlling the temperature at 400-550℃ to optimize the ductility.
- Pickling activation: Use acidic solution (such as tinning flux) to remove surface oxides and enhance the adhesion of plating.
2. Tin plating process
- Plating solution configuration: use stannic acid or tin chloride plating solution, temperature control 250-260 ℃ (to prevent oxidation and tin tumors).
- Plating process: Form a uniform tin layer by electrochemical deposition, the thickness of the layer is 3-12μm, and support salt spray test ≥ 240 hours.
3. Post-treatment and testing
- Cooling and insulation: air or air-cooled and wrapped with insulating materials (e.g. heat-shrink tubing or impregnated paint).
- Quality control: Test conductivity, plating thickness, insulation strength, complying with IATF 16949 and RoHS standards.
Tin Coated Copper Busbar Car battery Bus bar Feature:
Akusüsteemis on siinid kriitiliste komponentidena elektrienergia tõhusaks jaotamiseks akuplokis. Siin on siinide kasutamine akudes:
1. High conductivity and low loss
– Copper substrate combined with tin plating layer, taking into account the conductivity efficiency (close to pure copper) and surface oxidation resistance, reducing energy transmission loss.
2. Environmental resistance
– Tin-plated layer to isolate moisture, salt spray corrosion, suitable for automotive battery packs, high temperature, vibration environment.
3. Flexible design
– Multi-layer copper foil laminated structure supports multi-angle bending, suitable for complex battery module layout.
4. Integration and light weight
– Voltage/temperature sensor signal lines can be integrated to reduce overall weight (50% weight reduction compared to aluminum busbar).
Tin Coated Copper Busbar Car battery Bus bar Application:
- Power battery pack: cylindrical/square battery connection for Tesla, BMW and other models.
- Charging system: conductive module for high-voltage fast-charging pile, supporting 800V high-voltage platform.

Mis kasu on siinist akus?
Akusüsteemis on siinid kriitiliste komponentidena elektrienergia tõhusaks jaotamiseks akuplokis. Siin on siinide kasutamine akudes:
1. Current transmission and distribution
– Connecting battery cells to form series/parallel circuits, realizing efficient energy transfer and reducing contact resistance (laser welding technology reduces heat loss).
2. Thermal management support
– Copper’s high thermal conductivity (401W/mK) helps to dissipate heat, avoiding localized overheating and triggering thermal runaway of the battery.
3. Mechanical Stability
– Rigid structure supports the battery module to resist displacement caused by vehicle vibration and enhance safety.
4. Signal Integration
– Part of the hybrid bus integrates BMS signal lines to monitor battery voltage, temperature and other parameters in real time.
