If you want to increase the MPG on the electrical system how about doubling the Voltage from 12 to 24 volts? Power is Power I x E = P. If you double the Voltage E, and keep the P Power constant, then you Half I, the Current. All the wiring can be of a thinner gauge and the weight can be reduced. We keep hearing, "Take the weight out of the Trunk." The use of Plastics because they are lighter.
Other countries use 240 Volts? Less Grid losses. Thinner wires.
24 volt batteries for the Trucks and Diesel engines.
They have gone from 6 to 12V. Why not 24? or 48?
