In the rapidly developing automotive world, many research and development studies are carried out on battery electric vehicles (BEVs), known as new-generation vehicles. Among these studies, the subject of regenerative braking also attracts attention, and studies on this subject continue intensively. In fact; the purpose of these studies is to increase the amount of the energy recovered by regenerative braking in BEVs. In addition, the studies on the braking system; is to provide optimum braking safely and increase the amount of recovered energy by making maximum use of the torque capacity of the electric motor and minimum use of frictional braking, provided that the braking balance between regenerative braking and frictional braking is maintained throughout braking. In other words, it should be worked to make safe and regenerative braking as effective as possible. Within the extent of this study, vehicle dynamics modeling of the relevant vehicle has been investigated numerically with MATLAB/Simulink software, using the parameters of the Renault ZOE R135 vehicle. Afterward, the effect of different distributions such as ideal brake force distribution (I curve), actual brake force distribution (β curve), ECE (The Economic Commission for Europe) brake force distribution, and modified ECE brake force distribution on the amount of energy stored in the batteries has been calculated. In addition, as a result of numerical studies, it has determined that with safe regenerative braking, the battery charging rate fluctuated during the 1800-second driving cycle, which showed that regenerative braking took place and the battery is charged.
