The plug-in type pure electric automobile charges electric energy into a vehicle-mounted power battery energy storage system through a ground charger, and the vehicle converts the charged electric energy into kinetic energy to enable the vehicle to run. In the prior art, the current during charging cannot be large enough, so that the whole charging process is very slow, and some batteries even need several hours, and although the power lithium battery or other types of batteries have the characteristic and the capability of quick charging, many applications are limited by the instant high-power charging bottleneck of the charging device, so that the whole charging process cannot be completed in a short time.

The super capacitor production technology is mature, the possibility is brought to the realization of a novel power supply storage device, the super capacitor is used for storing electric energy at present, the charging time can be greatly shortened, the capacitor discharging time is very fast due to the fact that the property of the capacitor is determined, the existing super capacitor can only last for 5-10 minutes, and therefore the motor of the motor car can only be powered for 5-10 minutes to rotate, and the inventor provides a magnetic motor with intermittent power supply in a period, and the magnetic motor drives the motor to rotate by utilizing the instant repulsive force of an electromagnet; the instant discharge time is about 1/50 of the time taken by the magnetic motor to rotate one turn, and the magnetic motor is maintained to rotate for more than 3 hours by supplying energy according to the capacitor continuously discharged for 5 minutes. According to the normal electric vehicle speed, the magnetic motor can continuously rotate by means of intermittent energy supply as long as the energy required by the instantaneous repulsive force of the electromagnet can maintain one circle of rotation of the magnetic motor. The maintenance rotation of the magnetic motor needs a complete charging and electricity storage control system to realize.
