Abstract:

This paper presents a bidirectional integrated charger drive system of Electric Vehicles (EVs) that is intended to be efficient, compact, and enhance the safety of batteries. The architecture incorporates a three-phase AC/DC converter having active Power Factor Correction (PFC) as well as a bidirectional buck-boost DC-DC converter, which provides a seamless charging and driving Integration unlike the traditional forms of integrated charger, which recycles the stator windings of the motor as a grid-side filter, which introduces torque ripple, acoustic noise, and complex control. The proposed design has a Permanent Magnet Synchronous Motor (PMSM) as the only propulsion, which will minimize the hardware and maximize the driveability. It consists of the adaptive charging strategy approach based on the real-time feedback of the temperature of the battery and State Of Charge (SOC), supplemented by a first-order thermal model, allowing fast charging with enhanced safety and protection of the battery. The simulation findings show a unity power factor, high efficiency of 97.2%, low Total Harmonic Distortion (THD) of 1.62%, smooth conversion between A Constant Current (CC) and Constant Voltage (CV) charging system, in addition to improved performance of the motor operating in drive mode. The proposed architecture combines adaptive battery-aware control with the conventional utilisation of PMSM-based propulsion to offer a high-performance and scalable way for next-generation electric vehicles.
