A method for the providing and generation of constant motive power for electric vehicles to travel on roads uninterruptedly using high voltage alternator and transformers/substationstep-up transformers and/or step-down down transformers to appropriate desirable is disclosed. The present invention presents the idea of using a combination of a high voltage alternating circuit induction motor and a step-down transformer and their embodiments to step the voltage down to more desirable and useable level of volts depending on the capacity/size for a continuous supply of electricity for electric vehicles. The present invention allows electric vehicles to operate without distance limitation or battery pack losing power and whose disposal is an environmental hazard apart from cutting or reducing greenhouse gas as few or there will be no more mass production of internal combustion engines. The present invention uses high voltage from an alternator whose voltage is increased by a step-up transformer then goes through a substation and this power is decreased by a step-down transformer so that a lower voltage powers electric vehicle of all sizes/capacity. The summary is that when the power is passed through the step-up transformer, the primary side has few turns of wire; and the voltage decreases; and current is increased; but in the secondary side, with more turns of wire, the voltage increases but the current is decreased. In the case of the step-down transformer, the voltage is increased in the primary side with many turns of coils, but on the secondary side with few turns of coils, the voltage is decreased, and the current is increased, thus giving the vehicle power to operate.
