Boltshauser, S., Hibon, T., and Mateu, R., "Development and Integration of a Regenerative Braking System into a Full-Electric-Vehicle," SAE Technical Paper 2013-01-0062, 2013, doi:10.4271/2013-01-0062.
Driven by the will to gain further know-how and experience in the field of electric vehicles, and to demonstrate IDIADA's engineering capability, IDIADA decided to convert an existing light commercial vehicle, a Nissan Cabstar, into a fully electric vehicle.The brake department of Applus+ IDIADA investigated and developed different concepts of Regenerative Braking Systems (RBS) for this Electric Vehicle project, all of which based on the existing braking system, but with extended sensors. Thanks to their developments and technologies, Applus+ IDIADA succeeded in demonstrating the potential of electric vehicles.This presentation, with focus on the development and integration of the concept, aims at giving a brief overview on the results achieved so far. Based on the investigation and testing of the conventional braking system, several simulations with different concepts and control logics result in the best possible compromise between costs and system efficiency, allowing this concept an optimal performance. Furthermore, this presentation will deal with the application of the concept to the vehicle, e.g. calibration and validation of the concept when integrated into the vehicle.
