Abstract

Electric vehicles face problems regarding energy supply. Since the main energy used in electric vehicles is electrical energy that comes from certain energy sources such as batteries and capacitors, the amount of energy that can be stored in an EV is determined by the energy density of its energy source. A common method of dealing with this problem is to increase the size of the battery or capacitor. On the other hand, by increasing the size of the battery or capacitor, the weight of the electric vehicle will also increase, this will make the EV^s mileage shorter. Therefore, the regenerative braking control strategy is the best solution. Regenerative braking of electric vehicles can save energy wasted from the braking process. Regenerative braking system can convert kinetic energy into electric energy to prolong running. This paper proposes a regenerative braking control strategy which is fulfill two aspects, energy saving efficiency and safety. Safety ensures safety in driving when braking, especially handling a braking level to prevent slip on the wheels. Energy saving efficiency determines the energy wasted to be capture during braking in the optimum value. In this paper, predictive control model to be proposed to maintain the braking process and get an optimum energy intake. In the end, the effectiveness of the proposed strategy was verified through a simulation of a three-wheel electric vehicle model based on Matlab/Simulink.
