N2 - Integrated onboard battery charging (IOBC) is an emerging technology that utilizes the same circuitry used for propulsion to charge the battery packs of an electric vehicle (EV). Multiphase machines are the better choice for IOBC owing to their high current, fault-tolerant capability, and reduced modification requirements to achieve zero average torque. In this digest, a six-phase interior permanent magnet synchronous machine (IPMSM) was specially designed for the propulsion and IOBC of an e-Golf. Two different winding configurations, i.e., dual three-phase and asymmetrical, were tested for propulsion and IOBC. In both cases, zero average torque in charging mode was ensured. A predictive current control algorithm was used to charge the battery using constant current. Furthermore, the vehicle-to-grid (V2G) mode was also tested using both winding configurations, and the results were compared. The simulation was carried out using finite element analysis and MATLAB Simulink. The simulation results are verified using a 15 kW IPMSM hardware-in-loop-based control system and power grid emulator.
