Electric Vehicle Energy Conservation to Improve Range and Performance

Electric vehicle range must be extended to make electric vehicle use attractive. Other than propulsion, climate conditioning is the heaviest user of energy. An efficient, novel climate control system coupled with an energy management system is described and its energy usage is estimated and compared to that of a conventional system. The example presented here is for a shuttle bus used for carrying approximately fifteen passengers on short, frequently repeated routes, but the concepts are equally applicable to personal electric vehicles.
