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:
The goal is to compare swappable battery systems with fast-charging for battery-electric construction machinery.
The aim is to develop a parameterized total cost of ownership (TCO) model that allows for a comparison of both energy management concepts over the life cycle of a construction machine. The associated infrastructure (charging stations, battery swap stations, etc.) must also be taken into account. Furthermore, battery degradation plays a significant role, as it can be the deciding factor for battery swapping. Finally, scenarios (e.g., construction machinery types / construction site types / energy supply / annual operating time / depreciation period / etc.) are to be identified under which battery swapping is economically advantageous.
With this project, you have the opportunity to contribute to a hot topic in the construction machinery industry. Swappable batteries are already being used on certain construction sites, but are neither commercially available nor the subject of extensive research. You will also gain valuable experience in the areas of battery technology, cost modeling of technical developments, and scenario analysis. Your findings are highly relevant, as our industry partners are also showing great interest in this topic.
Work Packages:
- Literature review on TCO models for electric vehicles and construction machinery, battery degradation under fast-charging conditions, key metrics on machine usage profiles
- Development of a parameterized TCO model including initial and ongoing costs (CAPEX & OPEX) for the machine and the necessary infrastructure
- Integration of a battery degradation model
- Analysis of various usage scenarios and sensitivity analysis to identify cost-relevant parameters
- Visualization of the results and identification of favorable conditions for battery swap systems
- Voraussetzungen
- Independent and strategic way of working
- Passion for e-mobility
- Ideally initial knowledge of battery systems and off-highway machinery
- Ideally an interest in cost-benefit analysis
- Ideally experience in programming with Matlab or Python
- Enjoy working in a team
- Very good German or English language skills
Benefits:
- be part of a huge research project with other universities and 17 industry partners (ForBat@Bau)
- option for construction site or industry partner visits
- work together and exchange ideas with other students
- the project just started, so you can shape the topic with your innovative ideas actively
there is more to come: many possibilities for a follow up Master's thesis
