Abstract
The invention discloses a self-charging method for an electric vehicle with a direct-current permanent-magnet brushless generator. When the electric quantity of a battery pack of the electric vehicle is detected to be consumed to a given value by a detector of the generator, the battery pack is controlled by a generator controller to supply power to the direct-current permanent-magnet brushless generator, so that the direct-current permanent-magnet brushless generator is transformed into a starting motor to realize self-starting. When the rotating speed of the direct-current permanent-magnet brushless generator is detected to reach a first critical speed by the detector of the generator, a mechanical power device is controlled by the generator controller to start. When the rotating speed of the direct-current permanent-magnet brushless generator is detected to reach a second critical speed by the detector of the generator, the battery pack is controlled to stop supplying power to the direct-current permanent-magnet brushless generator; and the self-starting is over. The direct-current permanent-magnet brushless generator keeps on being driven by the mechanical power device to rotate to generate electricity; one part of the generated electric quantity is used for supplying power to a motor of the electric vehicle so as to enable the electric vehicle running normally; and meanwhile, the other part of the generated electric quantity is used for automatically supplying power to the battery pack of the electric vehicle to reach a charging given value.
