CONTROL SYSTEM FOR EXTENDED DRIVING RANGE IN ELECTRIC VEHICLES

Carlos Armenta-Deu

Abstract

This paper is aimed at designing a control system that regulates the power and energy supply to the electric engine to optimize the battery use, so the driving range of the electric vehicle can be extended. The method is based on controlling the acceleration of the electric vehicle and maintaining it within specific limits as well as to use the inertial forces to help the vehicle in saving energy while running. The proposed protocol is based on a limitation of the maximum velocity allowed to an electric vehicle in urban routes but within reasonable values, so the time interval of the route is not extended very much. The protocol combines inertial and powering forces to attain an average velocity for the entire route that not exceeds 10% of the original time interval, but saving more than 35% of the energy, thus enlarging the driving range by 20%. A simulation process has been conducted in a scale model proving the validity of the proposed method. KEYWORDS: Control system. Electric Vehicle. Dynamic restrictions. Extended Driving Range.
