Vehicle simulation of an electric street sweeper for substitution analysis

Abstract

Small street sweeping machines are important for a clean city. A permanent use guarantees clean sidewalks and public spaces and shapes thus considerably the overall picture of a modern metropolis. However, these uses have significant impact on the environment. There are not only CO₂, NOX and PM10 ejected, it will also increase noise emissions. The switch to electric mobility can locally reduce these emissions and allows additionally low-noise operations.

But the changeover to electric mobility carries high risks and costs. To estimate costs and possibilities a full vehicle simulation can be helpful (e.g. for designing battery size, planning tours).

In the project EBALD, a small electric street sweeper will be realized by the Laboratory of Electric Mobility from the HTW Dresden.

Based on collected field-data, collected during the project a simulation tool for substitution analyzes was realized. Using this tool, it’s possible to say, which conditions must be fulfilled (e.g. position of charging stations) to realize environmentally friendly and future-oriented cleaning concepts.

This paper includes a structural approach of such a full vehicle analysis.
