Summary:A Review on the integration of brake performance and energy efficiency optimization of regenerative braking system Aihong Meng, Charles A. Garris Department of Mechanical and Aerospace Engineering, The George Washington University Email: firstname.lastname@example.org Electric vehicles (EVs) are growingly popular due to its environment friendly features. The electric combining with intelligent technology will be the trend of vehicles in the future. In addition to the power battery, regenerative braking system has also been developed to improve the EV’s cruising range. since this technology recovers electric energy during deceleration. During regenerative braking, driving motor is operated as a generator which converts kinetic energy to electricity and exerts a brake torque on the vehicle simultaneously. The performance of the regenerative braking system influences the EV’s stability, brake comfort and energy efficiency. This paper presents a review of regenerative braking system, especially on the integrated optimization of brake performance and energy efficiency, which is references for the development of EVs. In brief, the paper is organized as follows: First, the structure and principle of the regenerative braking system is presented. Secondly, the method of braking force distribution is analyzed based on the comprehensive consideration of the energy efficiency, brake safety and brake comfort. Thirdly, the comparisons of control strategies are discussed, such as an adaptive control, sliding mode control, fuzzy logic control, artificial neural network control,etc. Finally, some conclusions of the study are presented.
