The limited range and slow/inaccessible charging infrastructure of electric vehicles (EVs) makes it hard to justify the purchase of new EV. This is exacerbated by the higher cost of EVs compared to traditional internal combustion vehicles. This thesis proposes a drivetrain-integrated charging system which addresses some of the barriers hindering the widespread adoption of EVs. A drivetrain-integrated charging system is an EV charger that resides on-board the vehicle which re-purposes pre-existing components on the vehicle to constitute the required charging circuit. In other words, it leverages the power electronics and electric machine in the drivetrain to serve as part of the high voltage battery charging system. The proposed integrated charger is based on the dual-inverter drive, consisting of two traction inverters, two batteries and an open-winding machine. The addition of two extra half-bridge modules enable this drivetrain to directly connect to and charge from a single-phase AC grid at power levels comparable to the power rating of the drivetrain. A further addition of a small capacitor divider enables the charger to also serve as the receiver power electronics in a wireless power transmission system. The developed control schemes allow for regulating the charging rate of both batteries from either source with excellent efficiency. Bidirectional operation is also possible during single-phase AC charging, in order to provide grid support or to supply external loads, such as appliances, tools or even other EVs or homes. Simulation and full-scale experimental testing validated single-phase AC and wireless charging. Single-phase AC charging is demonstrated up to 19.2k W with peak efficiency over 97%. Wireless charging is demonstrated up to 6.6k W with a peak efficiency of over 95%. Practical considerations, such as user safety (and standards compliance) was verified experimentally using the full-scale system considering all applicable parasitic elements. Overall, the developed integrated charging solution can save cost and space on-board the vehicle while offering additional/improved functionalities compared to existing discrete solutions in use today. This can make EVs more attractive for potential adopters.
