<p>A control device for a self-generating unit and a battery charging-discharging and switch unit for a kind of electric vehicle comprises a generator mounted on a wheel and a charging-discharging device having an input connected with the generator and an output connected with a driving means. There are more than two sets of batteries, a charging-discharging control terminal of which is such connected with a charging-discharging switch control circuit that at least one set of battery is in a charging state and the other sets are i a discharging state. The device of the present invention can be mounted on an electric vehicle. When the vehicle is moving, electric energy is generated with the self-generating unit and may charge the batteries to add its energy. By means of charging-discharging switch for multiple sets of batteries by turns it is guaranteed that the electric vehicle has relatively long drive time.</p> |
