| The main purpose of this thesis was to develop models of the components of an electric vehicle (EV), and validate those models through experimental data. A preliminary model of the mechanical and electrical aspects of the EV was first developed. This model was used to create an initial design of an EV that would be able to fulfill its intended purpose as a parking patrol vehicle.;The model of the EV developed in this thesis was used to estimate its energy requirements with and without the use of regenerative braking. This estimate was used to estimate the size of battery needed for the vehicle.;The experimental data obtained and models developed in this thesis were intended to improve the accuracy of subsequent modelling, simulation and design of the electric vehicle. The sizing of the battery would require a repetition of the modelling and simulation of the EV, showing that the design and modelling processes of an EV are iterative.;Three experiments were performed to collect data used to develop the model of the EV. These included vehicle deceleration trials, electrical and mechanical loading of dc motors, and the creation of driving schedules. The vehicle deceleration trials, known as "coastdown trials", were used to determine the parameters of the vehicle model. The motor loading tests were then used to develop and validate the motor model. In the third experiment, unique driving schedules that represented the intended use of the EV were created. |
