Vehicle power flow simulations based on trajectories with inductive charging systems: A case study

This article describes the study of power flows inside an electric commuter bus with a propulsion system that is powered wirelessly while the vehicle drives along its realistic trajectory in the context of public transportation. A dedicated bus model, that has been validated, is built in Matlab/Simulink incorporating inductive powering capability. The simulation method is based primarily on a `backward-looking´ calculation approach. A passenger bus and different bus drive cycles are simulated considering different wireless powering strategies: basic approach, charging at bus stops, powering when the vehicle´s energy storage system reaches a low charge level. Energy impact and requirements for the different situations are investigated.
