Why Copper Busbars Are Critical for the EV Revolution
Posted on: 12 Jun, 2025
The world is shifting gears toward sustainable mobility—and at the heart of this transformation lies one key enabler: copper. As EV adoption accelerates, OEMs and Tier 1 suppliers are under pressure to design smarter, safer, and more energy-efficient vehicles. And copper busbars are emerging as one of the most crucial components in making that possible.
Understanding the Role of Copper Busbars in EVs
In an electric vehicle, electrical current must flow smoothly and safely between systems like the battery, motor, inverter, and charger. That’s where copper busbars come in. These solid conductors, often flat and compact, enable:
- Efficient current transfer
- Thermal stability
- Compact packaging
- Reduced wiring complexity
- Increased reliability
Key EV Applications of Copper Busbars
- Battery Packs – Connect cells/modules and carry large currents safely
- Inverters – Enable conversion of DC to AC for motors
- On-board Chargers (OBCs) – Manage and regulate charging
- Power Distribution Units (PDUs) – Efficiently distribute energy across subsystems
- High-voltage Junction Boxes – Ensure safe connections across circuits
- Thermal Management Modules – Assist with heat dissipation
Why Copper Over Aluminum?
While aluminum is also used in electrical systems, copper remains the preferred choice for EV busbars because:
- Higher electrical and thermal conductivity
- Less cross-sectional area needed for same current load
- More durable under thermal cycling
- Allows tighter bends and compact designs
The Custom Advantage
OEMs and Tier 1s need tailored solutions that align with their EV platform architecture. Custom copper busbars offer:
- Designs optimized for specific current loads
- Shaped to fit compact EV assemblies
- Corrosion-resistant coatings
- Connector or insulation integration
