Beschreibung

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 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 directly.

 

Thesis Topic:

This thesis focuses on the requirements on battery (swap) systems for electric construction machinery. The objective is to identify customer-relevant properties through expert interviews and data analysis of construction machinery data. Furthermore, different design parameters of battery systems should be determined by literature research. Thereafter, a method should be developed and applied to evaluate existing and future concepts of battery systems for construction sites regarding their suitability. 

 

Work Packages:

• Literature review and state-of-the-art analysis on electric construction machinery and battery swap systems
• Research on design parameters and customer-relevant properties of battery systems for construction sites
• Expert interviews and/or data analysis in order to determine parameters and properties

• Research and application of evaluation criteria for design concepts

   

Voraussetzungen

• Independent and strategic way of working
• Passion for e-mobility 
• Ideally initial knowledge of battery systems and off-highway machinery 
• Ideally experience in programming / data science 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
