Motivation:
The construction industry is a major contributor to global CO₂ emissions, particularly due to the use of diesel-powered machinery on construction sites. Battery-electric construction machines offer a promising pathway to reduce these emissions due to their high efficiency and local emission-free operation. However, the integration of electric machines into construction processes poses new challenges. Limited grid capacity, fluctuating power demands, and the lack of systematic planning approaches for energy supply and storage require a more holistic view of construction site operations. In particular, the design of suitable energy systems - including grid connection, battery storage and charging infrastructure - becomes a key enabler for the successful deployment of electric construction equipment. In addition, emerging concepts such as battery swapping, bidirectional charging and vehicle-to-vehicle (V2V) energy transfer offer new opportunities to increase system flexibility and reduce peak loads by enabling machines to exchange energy flexibly.
Thesis Topic:
With this project, you have the opportunity to contribute to a highly relevant topic within the construction industry, as well as machine manufacturers: Is battery-electric construction machinery economically advantageous to conventional diesel machinery, and if yes, under which conditions is this the case? You will gain valuable experience in electric mobility, the construction industry, cost modeling of technical developments, and scenario analysis. Our industry partners are showing great interest in this topic.
The aim is to develop a parameterized total cost of ownership (TCO) model that enables comparison of battery-electric and conventional diesel construction machinery over their life cycles. This should be done for different machine types (wheel loaders, excavators, rollers, etc.) and different construction site scenarios. This can contain the different usage patterns of machines as well as the charging infrastructure (grid access, battery transport, etc.). Finally, future scenarios (changes in energy or battery prices, higher production volumes, etc.) should be analyzed to identify scenarios in which battery-electric construction machinery is economically advantageous.
Work Packages:
- Literature review on TCO models for electric vehicles and construction machinery, machine usage profiles, and construction site energy supply
- Development of a parameterized TCO model including initial and ongoing costs (CAPEX & OPEX) for the machine and the necessary infrastructure
- Analysis of various usage scenarios and sensitivity analysis to identify cost-relevant parameters
- Visualization of the results and identification of favorable conditions for battery-electric construction machinery
- Voraussetzungen
- Independent and strategic way of working
- Passion for e-mobility
- Ideally initial knowledge of battery systems and off-highway machinery
