Power System for Automotive
Due to Copper's high electrical, thermal conductivity, and durability, copper becomes an essential material for automotive applications, spanning traditional combustion engines to electric vehicles (EVs). Key products ainclude:
√ Combustion Engines
- 1. Cooling systems, copper alloys in radiators and heat exchangers ensure efficient thermal management.
- 2. Braking systems, copper-based brake pads and hydraulic lines enhance corrosion resistance and reliability.
- 3. Electrical components, low-voltage wiring harnesses and connectors rely on copper for stable signal transmission.
√ Electric Vehicles
- 1. Electric motors, high-purity copper windings, hollow conductor, maximize energy efficiency and power density in EV motors.
- 2. Battery systems, copper foils and busbars are critical for lithium-ion battery cell interconnects, reducing energy loss.
- 3. High-Voltage cables, copper cables (e.g., 600V+) transmit power between batteries, inverters, and motors minimal resistance.
√ Shared applications
- 1. Wiring harnesses & connectors, copper alloys dominate automotive wiring due to flexibility and conductivity, even in extreme temperatures
- 2. Sensors & electronics, advanced driver-assistance systems (ADAS) and infotainment systems use copper in circuit boards and connectors.
- 3. Synchronizer rings, manganese-copper alloy rings improve gear-shifting precision in transmissions.
In general, a conventional car consumes around 20-25kg of copper & copper alloy materials, while EV cars uses around 60-80kg. Copper's role in EVs makes it a strategic resource for the clean energy transition. Its unique properties, combined with surging demand, position it as a critical material for decarbonizing transport and energy systems.
