Required power and energy demand determination of the vehicle in a movement for the particular route

Abstract

This paper presents a method for power and energy demand estimation of a vehicle based on data obtained by a GPS device. During the selection process of the GPS device, it is necessary to take the sample rate and speed measurement accuracy into consideration. The power of an electric motor and energy of a battery pack need to be determined during the designing process intended for a conversion of a conventional vehicle to an electric vehicle. Drive requirements can be determined by measuring speed and torque on a drive wheel using a torque meter. Obtained traction profile is used for electrical drive designing purposes. The required power and the energy consumption of the vehicle can be calculated using speed and altitude profile from the measured route and the resistance model of the vehicle. The calculation for the Steyr 15S18 utility vehicle is proposed.
