Regenerative Braking Performance of Different Electric Vehicle Configurations Considering Dynamic Low Speed Cutoff Point

This paper addresses the improvements gained by considering a dynamic Low Speed Cutoff Point (LSCP) as an alternative to a constant LSCP for regenerative braking of Electric Vehicles (EVs). The energy harvesting improvement is studied using an EV test bench simulation model in MATLAB/SIMULINK for different vehicle configurations of single axle and all-wheel drives. Different scenarios are studied on a standard drive cycle and the improvements in each case are compared with each other. The simulation results proved that considering dynamic LSCP instead of constant LSCP improves the regenerative braking capability of EVs regardless of the configuration. This improvement is more significant when considering a rear-wheel drive EV.
