Abstract: The electric bike is a very good educational system because it can be used by all students without problem of safety. When pedaling on the electric bike, the student can identify with the motor drive and understand the meaning of torque, speed and power. This educational system uses many modules of Electrical Engineering: power converter, battery, motor, controller, electronics, lights, instrumentation, sensors, mathematical modeling, mechanics... Thus, many technologies can be presented. These vehicles have a difficult compromise between weight, power, battery life, and price. These vehicles could be implemented using new composite materials and new Lithium batteries. But to increase the lifespan of the batteries, which represent 35 % of the electric vehicle price, we will demonstrate the benefits of a control with constant power through the motor, compared to a control with a constant force. This paper will outline the resistive power, as a function of vehicle speed and the state of energy consumption. A comparison of energy prices between different kinds of electric vehicle will be presented. The advantages and disadvantages of using super capacitors will be presented, as well as energy management on board the motor speed controller. Then, an overview of the regulation of a fast charger with current control and voltage control will be presented. Finally, many educational applications will be presented around the electric vehicle realized.
