The automotive industry is in transformation. The complexity of the automobile has increased exponentially in the past decades and has triggered a design revolution that stresses detailed modeling and simulation steps prior to committing to metal and plastic. With new generation vehicles deploying hybrid (HEV), fully electric (EV), and fuel cell powerplants, the need for advanced physical modeling solutions is considerably greater due to increasing system complexity. This webcast covers new approaches to modeling and simulation for HEV and EV vehicle applications with emphasis on the development of high-fidelity physical models of automotive batteries. To speed up the design and prototyping processes of HEVs, a method that automatically generates mathematics equations governing the vehicle system response in an optimized symbolic form is desirable. To achieve this goal, the physical modeling tool MapleSim was employed to develop the multidomain model of a series-HEV, using the symbolic computing algorithms of the Maple software package to generate an optimized set of governing equations. The HEV model consists of a mean value internal-combustion engine, a Li-ion battery pack, and a multibody vehicle model. Simulations are then used to demonstrate the performance of the HEV system. Simulation results show that the model is viable and the number of governing equations is reduced significantly, resulting in a computationally efficient system. Webcast attendees will be invited to interact with the speakers during the program's live Q&A segment.
