Winnebago Electric Motorhome on a F-53 chassis

Brett is right, I'm guilty. Not only power generation, but the battery manufacturing is a dirty affair. You can compare the lithium batteries to our deep cycle batteries. Their is a limit to how far they can be discharged. Unlike lead acid batteries, the voltage of the lithium batteries remains fairly constant until they are over discharged. My experience with them is once they are over discharged, they are ruined. This is why the electric and hybrid have such expensive and completed control systems, and cooling to the batteries and controls. If it is a all electric vehicle, what about the steering, and AC? Will there be an extra battery to run these things, or a pony motor to operate these, or a generator to help some of the load? Yes, these problems have been solved in cars which weigh less than 5,000 lbs. We do have a hybrid and everything is electric, steering, brakes, AC, trunk, seats. In the summer, we get about 36 mpg, when not using the AC we get near 40 in town, and between 42 and 44 mpg on the highway. Point is the engine runs more in the summer because of the AC use. In 15 years, there may not be an ICE in passenger cars, but pickups.... I doubt it, let alone anything larger that works for a living.
