e-NUE: Co-Simulation of Electrified and Connected Vehicles

Logo-Schaufenster-Elektromobilitaet

Project Description

The transition from classic combustion engine to electric vehicles is a major step to reduce worldwide CO2 emissions. In order to correctly and efficiently investigate impacts on the electric grid and the dimensioning of charging infrastructure, or to explore new technologies for a further increase of the driving range, realistic simulation models are required.
In this project we develop an accurate yet computationally inexpensive battery and kinematic model – including recuperation and a range extender module – to be used in microscopic traffic simulation and to help study the performance of thousands of electric vehicles. The overall power balance is derived from the vehicle’s speed and a set of constant predefined parameters only, therefore the model can be easily coupled with current sophisticated traffic simulators (SUMO). The long period of the field trial (Schaufenster Elektromobilität, e-NUE) provides the necessary data and allows to validate the model’s behavior.
Another research focus is on the incremental substitution of combustion driven cars in vehicle fleets of companies. The simulations shed light on several questions: Regarding, for example, the optimal degree of electrification with respect to the utilization profile of the fleet, or the required charging infrastructure.
In order to investigate the optimization potential of Inter Vehicular Communication (IVC) on the power consumption, the vehicle model is extended by modules reflecting wireless communication devices. Based on that, a co-simulation framework – coupling traffic and network simulation (Veins) – is used to calculate the impact of Intelligent Transportation Systems (ITSs) on electrified vehicles.
