ISO Copper C11000 ED Copper Foil Applications in Electrical Vehicles

1. Description :

Electric and hybrid electric vehicles have reached a new level of development with introductions by Chrysler, Ford, General Motors, Honda and Toyota. Although a large market has not yet appeared, these manufacturers have invested significant effort and capital in development and testing and it appears EVs and hybrid EVs will be coming onto the market in significant numbers. Because an electric motor is used as the primary propulsion source, these vehicles will have a much higher copper content than a conventional vehicle which currently averages about 55 pounds of copper and copper alloys.

2. Impact of Electric Vehicles on Copper 

EVs have undergone a tremendous change since the first efforts of the Copper Development Association. In the early seventies ,  At this time an EV will use, on average, as much copper as a similar vehicle with an internal combustion engine. Most of the copper used for non-electrical functions is eliminated, such as thermal components and alloys in cast aluminum. However, the motor and increased electrical functions more than double the amount of copper used for wiring and connectors. Most EVs are using 250 - 350 volts in their power source, which means all connectors and wiring attached to the batteries, inverters and power controllers must be increased in size to handle the higher voltages and currents.

EVs and even hybrid EVs will use approximately twice as much copper as a conventional vehicle and this will provide the added advantage of excellent recyclability when the vehicle is removed from service.
