Electric vehicles (EVs) are gaining attention as a promising solution to reduce greenhouse gas emissions. This paper proposes system architecture of a Hardware-In-Loop (HIL) system to explore simulating the electric vehicle (EV) driving cycles using HIL testing approach. The HIL system uses an Arduino DUE as the controller, connecting MATLAB Simulink to an RC Car acting as the EV. It employs an L298N motor driver, B25, and ACS712 sensors to measure voltage and current behavior from an 11.1V 4200mAh Lithium-Ion battery. Simulink's GUI allows users to select desired driving cycles for simulation. Results show that the voltage decreases with speed, while the current increases as expected across various driving cycles (NEDC, WHVC, WLTP Class 1, UDDS, and SC03). This success confirms the HIL system's architecture capability to simulate and monitor battery discharging trends in terms of their voltage and current.
