Abstract :
This paper outlines the benefits of the constant power control compared to the constant force control.
The constant power control allows to cancel the intensity peaks supplied by the battery and have better dynamic speed.
Indeed, for the same energy consumption during acceleration, displacement is larger with the constant power control.
However, this control strategy causes a current peak motor. Therefore, there are trade off which exist between the constant power and constant driving force to control a motor.
Many curves present in theory and practice the two control strategies.
The power constant control is obviously applicable to any electric vehicle. We applied the two commands to 1500W brushless electric bikes from a test bench.
These bikes reach 60 km/h with a difficult compromise between weight, power, autonomy and price.
The constant power control is the most suitable because it increases the life of batteries which represent 35% of price.
The constant power control is achieved through regulation of the battery current and not of regulation motor.
However, a limitation of motor current priority must be made for low speed values. In addition, the battery current control makes it easy to limit the current to 1C during deceleration or downhill runs (regeneration).

Keywords : control strategy, electrical bike, torque control, power control.

Arnaud.sivert was born in France.
He received the Ph.D. degree from the University of Picardie Jules Verne, Soissons, France, in 2000.
In 1994, he joined an Institute University of Technology in the Department of Electrical Engineering, as an Assistant Professor.
His major research interest is the control of electrical machines
I.U.T has produced many prototypes electric vehicles since 2008 and participates in the French national challenge of electric kart.
In 2011, I.U.T participated in the first challenge of French National electric bike.

The e-bike as a teaching support is used in technical field activity as electrical engineering or mechanical engineering and also in theoretical field activity as physics and mathematics.
The e-bike teaching tool turns all mechanical or human parameters such as forces and powers into their electrical analogy representation.
The e-bike allows understanding some facts.
