Extending the driving range and enhancing the battery life are the main concerns with EVs nowadays. The drive motor (DM) used is a three-phase induction motor (IM), which is controlled by the current sensorless indirect vector control method. This fault-tolerant method can be used in the case of current sensor failure. All the resistive forces acting on an EV are emulated based on the concept of vehicle equivalent rotational inertia for different real-life driving cycles, namely ECE R15 and NYCC. The battery alone is not capable of handling the surge current requirement during the acceleration period and is not able to capture the total power during regenerative breaking as it has a low power density. Hence, a high power density source like UC is a must to handle these conditions during frequent stop and go city traffic conditions as per ECE R15 and NYCC driving cycles. This EV emulation technique helps in getting the DC-link power profile for an EV for any driving scenario. Hence, it is possible to test the different powertrain components of an EV using this proposed technique. © 2023 The Author(s). Published by Elsevier Ltd.

Introduction The transportation industry’s current focus is on modelling electric-drive vehicles in order to perform accurate simulations for a number of applications. Hardware-in-loop (HIL) simulations using a test bench are becoming increasingly popular [1–7]. In [8–10], a test bed is developed to test the energy storage system performance. In [11], authors estimated the stator currents by using rotor flux and stator voltage for a current sensorless vector-controlled IM drive. In [12], the current sensorless technique by using direct predictive control scheme for IM is presented. In [13], stator currents are estimated by using state variable of the differential equations. In [14,15], stator currents are estimated by using the single dc-link current sensor. In [16–20], the DM speed and energy management strategies are developed and validated using the motor-dynamometer experimental setup. * Corresponding author.
