Copper demand from electric vehicles to be nine times higher by 2027

This piece from the International Copper Association may be of interest to subscribers. Here is a section:

Electric vehicles use a substantial amount of copper in their batteries, and in the windings and copper rotors used in electric motors. A single car can have up to six kilometers of copper wiring. The metal is also required for busbars, used to connect modules and cells in battery packs, and in charging infrastructure.

Whilst most cars use internal combustion engines that require up to 23 kg of copper, the IDTechEX research found that a hybrid electric vehicle uses 40 kg of copper, a plug-in hybrid electric vehicle uses 60 kg, a battery electric vehicle 83 kg, and a hybrid electric bus 89 kg. A battery-powered electric bus can use 224–369 kg of copper, depending on the size of battery used.

“Copper has the highest conductivity of any non-precious metal, and plays an important role in all energy production, but it is particularly important for future sustainable technology applications such as electric vehicles,” said Colin Bennett, Market Analysis and Outreach, ICA. “Copper increases the efficiency and reliability of these vehicles and is itself a sustainable material, as it is 100% recyclable without loss of properties.”


Eoin Treacy's view

The automotive sector is betting big on electric vehicles while also attempting to figure out how autonomy will function and what that means for ownership and miles driven assumptions. With battery technology improving all the time and with considerable investment flowing into the sector the potential for the electric vehicle market to grow from its current relatively modest footprint is considerable. 

The copper price has been consolidating mostly above $2.50 since November but needs to sustain a move at least above $.2.70 to confirm a return to demand dominance beyond short-term steadying.
