A new electrically assist scooter

The present paper addresses the study of a new electrically assist scooter. Nowadays, every electrical scooter found in the market works with human action, either by using a throttle handle or pedal, to control the electrical motor speed and no one offers a real assistance. For proper design, the scooter behavior, with different users, has to be analyzed by way of speed measurements. From this, an ideal and a worst case can be established leading to the knowledge of the power, torque and energy required by the electrical assistance. A topology is proposed and an algorithm for proper assistance is presented. Finally, measurements performed on the real prototype illustrate the behavior of the assistance.
