Every electric vehicle is, in a very real sense, built around copper.
More Than a Marginal Increase
Copper is what allows electricity to move. It carries power from the battery to the motor, enables charging, and supports the growing network of electronics that modern vehicles rely on. As vehicles become more electrified, the amount of copper required increases significantly.
A conventional petrol or diesel car typically contains around twenty to twenty-five kilograms of copper. An electric vehicle can contain more than three times that amount. This is not a marginal difference; it reflects a fundamental shift in how vehicles are designed.
Where the Copper Sits
This increase comes from multiple sources. Electric motors rely on coils of copper wire to generate motion. High-voltage cables connect the battery to the drivetrain. Inverters, transformers, and charging systems all depend on copper's conductivity and reliability.
Even features consumers now expect, from advanced driver assistance systems to connectivity and onboard computing, further increase copper demand.
Beyond the Vehicle Itself
Charging infrastructure extends this demand even further. Fast chargers, grid connections, and local distribution upgrades all require substantial amounts of copper.
As electric vehicle adoption grows, it is not just the vehicles themselves that matter, but the systems that support them.
Why Substitution Is Limited
What makes copper particularly difficult to substitute is its unique combination of properties. It conducts electricity efficiently, resists corrosion, and performs reliably across a wide range of conditions.
Alternatives such as aluminium can be used in some applications, but often require trade-offs in efficiency, size, or durability.
A Shift Toward Materials
This creates an important dynamic in copper demand. As electric vehicle production scales, copper demand rises not only with the number of vehicles produced, but also with the increasing complexity of those vehicles and their supporting infrastructure.
It also highlights a broader point. Electrification is often framed as a shift away from fossil fuels; however, in practice, it also represents a shift toward materials, particularly copper.
Electric vehicles are not just powered by electricity. They depend on the ability to move it efficiently, and that depends, to a significant extent, on copper. They are not only about transportation; they are about materials, and at the centre of that sits copper.
