Teaching and development project for an eMobility bachelor course

To teach eMobility to bachelor students, a development project was set-up, to be undertaken by students. The aim is to explore the various aspects of eMobility by practical laboratory tasks. In the first phase of the project, an eKart was assembled. In this phase of the project, the electronic controls are implemented. To finally implement drive-by-wire in an eKart, the speed controls, communication and the drivers-display, are implemented in a single steering wheel. Communication with the speed controller and the battery management system, has to be included in this steering wheel. By implementing all controls, communication as well as the drivers display inside a single steering wheel, simplifies the final eKart design. Communication via a single SPI interface reduced the wiring inside the eKart and allows easier exchange during maintenance or upgrades.
