A battery electric car uses almost three times as much copper as a comparable petrol or diesel car, according to the International Energy Agency (IEA). The extra copper goes into the battery pack’s cabling and management system, the motor windings, the power electronics and high-voltage wiring. The exact kilograms depend on battery size, motor design and vehicle class, so treat any single per-car figure with care.
Key Takeaways
- A battery electric car uses almost three times the copper of a similar petrol car (IEA).
- The extra copper sits in the battery pack, motor, power electronics and cabling.
- EVs were about 2% of global copper demand in 2024.
- A charging cable holds only about 1–2 kg of copper.
Where the Copper in an EV Goes
Copper is used anywhere current must move with low losses. In an electric car that means far more places than in an engine-driven car.
| Part | Why it uses copper |
|---|---|
| Battery pack | Copper foil in many cell anodes, plus busbars, cables and the battery management system |
| Traction motor | Stator windings carry high current; copper keeps losses and heat down |
| Power electronics | Inverter, DC-DC converter and on-board charger use copper busbars, windings and circuit boards |
| High-voltage wiring | Thick orange cables link the battery, inverter, motor and charging port |
| Low-voltage wiring | The same type of wiring harness found in any modern car |
The IEA notes that in its 2025 analysis the copper used at battery pack level, including cables and the battery management system, is counted with the vehicle rather than with the cells. Battery materials and copper together make up around 15% of a battery electric car’s weight.
How Much Copper Is Used in Electric Vehicles Overall?
EVs are a growing but still small part of the copper market. The IEA found that electric cars accounted for about 2% of global copper demand in 2024 and are the fastest-growing source of copper demand, while their impact on the overall market remains limited. Electricity networks and buildings remain far larger users.
In the United States, the U.S. Geological Survey (USGS) reports that transportation equipment took about 18% of copper and copper alloy products, behind building construction (42%) and electrical and electronic products (23%). Copper was added to the U.S. list of critical minerals in 2025.
Copper in the Car vs Copper in the Charger
A charger uses much less copper than the car it charges. A typical 7.5 m portable or tethered cable holds roughly 1–2 kg, depending on conductor size. Inside the car, the on-board charger converts AC to DC, which is why a Level 2 unit is really a smart, protected power supply rather than a “charger” in the strict sense. Our guides on whether EV chargers are AC or DC and how home EV chargers work explain this split.
DC fast chargers move the conversion into the station, so they carry transformers, inductors and much heavier cables. See how DC fast chargers work.
What This Means for Charger Buyers
- Cable quality: the copper in the charging cable is where cost-cutting shows up first. Ask for conductor size and cable standard.
- Price sensitivity: copper is a modest share of a charger’s price, but it affects cable-heavy products such as long portable units.
- Supply chain: USGS lists Chile as the largest source of U.S. refined copper imports in 2021–24, so global events reach cable pricing.

Frequently Asked Questions
How much copper is in an EV compared with a gas car?
The IEA puts it at almost three times as much for a battery electric car. The gap comes from the battery pack, motor, power electronics and high-voltage cables.
Do hybrids use more copper than petrol cars?
Generally yes, because they add a battery, motor and power electronics, but less than a full battery electric car. Exact amounts depend on the design.
Will EVs cause a copper shortage?
EVs were about 2% of global copper demand in 2024, per the IEA. Grids and buildings use far more, so EVs alone are not the main factor.
