One of the most effective ways to improve energy efficiency in electric vehicles (EVs) is by reserving energy from regenerative braking. This paper presents an evaluation of the regenerative braking potential from the DC series motor in EVs. The dynamic model is derived by incorporating the electro-mechanical system of DC series motor and the vehicle's drivetrain dynamics and longitudinal dynamics. The derived model is based on a two-seater EV driven by a DC series motor rated at a nominal power of 11.4 hp and a nominal voltage of 48 V. A physical model of the EV drivetrain is built into the Simulink® environment to simulate and evaluate the dynamic characteristics of the drivetrain, including the potential use of the regenerative braking. The electrical and mechanical parameter values of the motor are identified based on experiments in two scenarios. In the first scenario, the driving wheels are lifted, in which only the rotational dynamics are incorporated into the simulation. In the second scenario, the driving wheels are emulated to be in contact with the road surfaces, in which both rotational and translational dynamics are included in the simulation. An auxiliary battery of 12 V nominal voltage is used to harvest energy from the regenerative braking. The simulation results demonstrate that the back electromotive force (BEMF) generated from the regenerative braking of the DC series motor may be reserved to charge the auxiliary battery successfully.
