Brake System Design for Dedicated BEV Architectures 2018-01-1870
As fossil fuel dwindle and more and more electric vehicles enter the market, there is an opportunity to reevaluate the standard brake system as we know it. This paper will discuss and compare the differences in brake system sizing between a non regen internal combustion engine vehicle and a dedicated battery electric vehicle. It will use a model derived from component dynamometer testing and vehicle test data of a mid-size production vehicle modified for the mass and regenerative braking capabilities of a battery electric vehicle. The contribution of regenerative braking energy will be analyzed and compared to show its impact on component sizing, thermal sizing, and lining life. The detailed design study will calculate the parameters for caliper, rotor design, actuation, etc., that are optimized for 100% regen enabled vehicles.
