Vehicle Performance Simulation of Electric Bus with Composite Power Supply Based on Secondary Development of Advisor
In order to improve the performance of the electric buses,composite power system is designed,which is analyzed and verified by the simulation using the software of Advisor. Advisor is secondary developed by updating assembly simulation models and vehicle models. The basic structure of composite energy storage system and the control strategy based on fuzzy theory are designed, and the simulation of vehicle performance is done under the road cycle of UDDS, and then compares with the bus with only batteries. The result shows that ultra-capacitor has a prominent "clipped peak and filled channel" protection for the battery, recovers energy commendably, and extends the battery’s life. The electric bus with composite power supply can meet the requirement of vehicle performance, and its indexes of all aspects are better than the electric bus with only batteries.
