According to statistics from the International Copper Association, in 2019, an average of 12.6 kg of copper was used per car, up 14.5% from 11 kg in 2016. The increase in copper use in cars is mainly due to the continuous updating of driving technology, which requires more electronic components and wire groups.
The copper use of new energy vehicles will increase in all aspects on the basis of traditional internal combustion engine vehicles. A large number of wire groups are required inside the motor. At present, most manufacturers' new energy vehicles on the market choose to use PMSM (permanent magnet synchronous motor). This type of motor uses about 0.1 kg of copper per kW, while the power of commercially available new energy vehicles is generally above 100 kW, and the copper use of the motor alone exceeds 10 kg. In addition, batteries and charging functions require a large amount of copper, and the overall copper use will increase significantly. According to IDTechEX analysts, hybrid vehicles use about 40 kg of copper, plug-in vehicles use about 60 kg of copper, and pure electric vehicles use 83 kg of copper. Large vehicles such as pure electric buses require 224-369 kg of copper.
