The study, by the Norwegian University of Science and Technology, is flawed.
They used a stationary industrial electric motor and associated components for their calculations instead of the motor from a typical modern EV.
They greatly overestimated the extra amount of copper used by an EV.
They analysed a battery chemistry not used by any production EV or plug-in Hybrid.
These errors mean the result is wrong.
And the original paper:
