Optimal contribution of energy management of electric vehicles

Abstract EN

An Electrical Vehicle (EV) has the advantage of being friendly with environment but it does not have the same performance as a current conventional vehicle.

This work proposes a strategy to improve the EV autonomy.

At first, an EV model that combines lead acid batteries and a DC motor is described.

The individual mathematical model for each component is developed in MATLAB.

Moreover, the control speed strategy using fuzzy logic is applied to the system to produce a maximum speed reference of an EV under different states of charge of the battery and acceleration.

Then, a proportional integral control adjusts the speed strategy.

When the vehicle is subjected to different scenarios, the simulation realized in MATLAB/Simulink will show good efficiency.
