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:

I et batterisystem tjener samleskinner som kritiske komponenter til effektiv fordeling af elektrisk strøm i batteripakken. Sådan bruges samleskinner i batterier:

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.
• Energy storage system (BESS): low inductance and high reliability power distribution in energy storage batteries.

Hvad er brugen af samleskinne i batteri?

I et batterisystem tjener samleskinner som kritiske komponenter til effektiv fordeling af elektrisk strøm i batteripakken. Sådan bruges samleskinner i batterier:

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.
