An electric vehicle for recreational areas and local traffic

The paper presents a lightweight vehicle, based on a frame made of metal tubes. Two novel electric disc motors are mounted directly into the front wheels and are controlled by an efficient electronic circuit that also provides an energy saving brake mode by charging the batteries with current gained through the braking process. The vehicle can transport an average family of 4 persons with a speed of 12 mph over a distance of 35-40 miles before recharging. Solar panels complement the battery power supply and provide up to 30% of the total energy for the regular drive mode. Considering the total costs of operation-a few cents per mile, when calculating with a life time of 500 charging cycles for the batteries and the additional use of solar panels-this vehicle can successfully replace a considerable part of the conventional car fleets of recreational or rehabilitation areas, and as a device for individual transport for shopping, business or leisure activities. The only limitations are set by the climate and by the topography of the operational area. Improvements in battery technology will further increase the chances on the market for this type of vehicle
