Prescriptive Modeling, Simulation and Performance Analysis of Mild Hybrid Vehicle and Component Optimization 2015-26-0010
Reckoning today's environmental rules, legislative regulation and market requirements- the automotive industry of late has witnessed an increased vigor and enthusiasm by auto makers towards electrification of vehicles across all platforms in a bid to improve fuel economy and performance.
Hybridization of a vehicle often involves the use of expensive high performance motors and large battery packs. However due to the challenges associated with the packaging of bulky battery and motor systems in existing drive train, mild hybrid systems have been preferred over strong or full hybrids especially in current production models as they don't entail any major change in architecture and the reduced battery size, both of which provide for easier packaging of components.
In this paper the authors present a generic model of a mild hybrid vehicle that can be effectively used to simulate any vehicle, enabled with a mild hybrid system to predict with approximate certainty the improvement in performance parameters and optimize component size. Thus, assist in selection and sizing of motor, battery and the associated operation voltage, with minimal monetary expense and time consumption. Consequently, an optimal system configuration for the prototype build is arrived while resulting in significant cost and time savings.
