On-board chargers face a lot of challenges like space, size, cost, and low power implementation so to confront these issues the on-board charger is integrated into the drive of the EV to reduce cost, size, and allow for high power fast charging implementations. Onboard chargers give the user the ability to charge the EV by plugging it to the convenience outlet which allows for level 1 and level 2 charging and as mentioned before integrating the charger to the motor allows for better performance for cheaper and less size. Integrating the charger entails the use of the inverter of the motor which is typically used for traction to be used as a bi-directional Ac-Dc converter and the motor windings are used as a filter inductor or as an isolated transformer. There are a lot of configurations for this method where some rely on the EV having two separate motors or a certain motor type and the integrated chargers are classified based on the number of motors and the number of inverters. All configurations depend on the EV being stationary since the inverter which is used for traction is used for charging.
