How do you convert an electric car?

These are rarely converted due to their excessive weight, instability, and inefficiencies (namely due to poor aerodynamics). To make the situation worse, many modern trucks/SUVs continue to get bulkier and heavier while their frames (or unibodies) are built thinner and lighter. As a direct result, the payload carrying capacity and thus the GVWR of the vehicles goes down. Such a trait is not desireable because it limits the weight of the battery pack that can be carried, limiting the maximum battery-to-vehicle weight ratio that could be achieved for the vehicle when converted to an EV. For a given battery type, reducing the battery-to-vehicle weight ratio always results in reduced vehicle range per charge. However, despite these mostly unavoidable limitations, several SUVs and larger trucks have been successfully converted to electric power by hobbyists. Some examples include the "Gone Postal" van converted to an EV racer by Roderick Wilde and Suckamps EV Racing, the 1971 Land Rover EV converted by Wilde Evolutions, and the 1988 Jeep Cherokee EV converted by Nick Viera.
