Research of drive model on electric vehicle

Drive model of electric vehicle (Ev) experienced from internal combustion engines to electric motors, to computer-controlled wheel motor-driven. At present there are several problems, such as without power consumption, small mileage, the high cost of manufacturing and use, and so on. To improve reliability, reduce costs, increase mileage, improve ride comfort, the paper designs a new Ev drive model by the DC wheel motors in series. Automatic differential speed by motors in series, remove drive by short-circuit switch, enhance drive voltage by voltage booster, CVT by PWM of the model. The model can achieve the differential of the process of turning or walking, CVT and the differential remove. Vehicles using the model have the advantage of comfortable, reliable, useful, and so on. The model can completely replace the current common model.
