Proof-of-concept projects have demonstrated that used electric vehicle batteries (EVBs), after their removal from electric vehicles due to insufficient performance, can be repurposed for less demanding applications. It is expected that numerous batteries will be available for repurposing in the 2020s. However, the information asymmetries and transa...
Nachdem im vorherigen Kapitel der Grundstein für ein konsistentes Begriffsverständnis geschaffen wurde und Begriffe wie Weiter‐ und Wieder‐ sowie Verwendung und Verwertung (Martens und Goldmann 2016) definiert wurden, sind erste EOL‐Strategien der Umwidmung und der Weiterverwendung von Traktionsbatterien beschrieben worden. Das Kapitel war denen em...
Im bisherigen Verlauf dieses Buches standen zunächst der Vergleich verschiedener End‐of‐Life‐Strategien für gebrauchte Traktionsbatterien und die Erläuterung mit der Strategie der Umwidmung und Weiterverwendung in Verbindung stehender zentraler Konzepte (z. B. des eEOL‐Passes) und Prozesse (z. B. für die Zustandsbestimmung gebrauchter Traktionsbatt...
Traktionsbatterien kommen in Elektrofahrzeugen in unterschiedlichen Formen und Größen vor und unterscheiden sich etwa entsprechend ihres Einsatzes in vollelektrischen Fahrzeugen, Plugin‐Hybrid‐Fahrzeugen und Hybrid‐Fahrzeugen (vgl. Kap. 1). Sie stellen zudem komplexe Systeme dar, die neben den Batteriemodulen und den in diesen enthaltenen Batteriez...
Die Umwidmung und Weiterverwendung gebrauchter Traktionsbatterien aus Elektrofahrzeugen unterliegt einigen Hindernissen. Insbesondere der hohe Grad an Unsicherheit der zukünftigen Alterung der Energiespeicher aus gebrauchten Traktionsbatterien und des Zustands der Batterie erfordern über die Sicherstellung der technischen Eignung hinaus Maßnahmen,...
Successful innovation is the key to generate novel business model ideas. Current real-world challenges such as the deterioration of the natural environment require practitioners and academics alike to identify new ways of acting and behaving. Living the ‘virtues of German engineering’ in information systems research, we aim at supporting business m...
Demand Response (DR) facilitates the monitoring and management of appliances in energy grids by employing methods that, for example, increase the reliability of energy grids and reduce users’ cost. Within energy grids, Smart Home scenarios can be characterized by a unique combination of appliances and user preferences. To increase their impact, a s...
This thesis was submitted in September 2016, graded in November 2016, and finally published with slight adaptations in June 2018.
Extract from preface:
This thesis analyzes barriers for establishing electric vehicle battery second use businesses and develops proposals for solutions to overcome these barriers. Three focuses dominate this thesis. Fi...
Der erste Teil dieses Buches adressiert die wesentlichen Grundlagen und Ziele des Cooperation Experience-Ansatzes (CXP-Ansatz) und bettet dessen Lösungsvorschläge in Fragestellungen zur Planung und Modellierung von hybriden Wertschöpfungsnetzwerken ein. Zentrale Herausforderungen bestehen vor allem in der bedarfsgerechten Koordination dieser Wertsc...
Der dritte Teil des Buches widmet sich der toolbasierten Unterstützung des CXP-Ansatzes durch eigens entwickelte Prototypen. Die Prototypen adressieren zwei zentrale Schwerpunkte, zum einen die durch die CXP-Modellierungssprache motivierte Modellierung der Wertschöpfungsnetzwerke und Verwaltung der erstellten Modelle, zum anderen die frühzeitige Er...
Zur Gestaltung und Modellierung der Zusammenarbeit im Rahmen von hybriden Wertschöpfungsnetzwerken wurde die CXP-Modellierungsmethode entwickelt, die im zweiten Teil dieses Buches vorgestellt wird. Die CXP-Modellierungsmethode offeriert den an der hybriden Wertschöpfung Beteiligten Sprachkonzepte, mit denen die Zusammenarbeit detailliert beschriebe...
The diffusion of electric vehicles suffers from immature and expensive battery technologies. Repurposing electric vehicle batteries for second-life application scenarios may lower the vehicles’ total costs of ownership and increases their ecologic sustainability. However, identifying the best – or even a feasible – scenario for which to repurpose a...
A balanced energy demand is challenging but beneficial for both energy providers and consumers. Demand-Side-Management (DSM) contributes to this by shifting flexible loads. Since various methods exist in DSM, it has to be evaluated which method can be deemed suitable for a certain situation in order to achieve the utmost value for the stakeholders...
Due to degradation effects, electric vehicle batteries (EVBs) have a lifetime of approximately ten years in electric vehicles (EVs). Recycling EVBs is inefficient and ecologically undesirable if the batteries can be repurposed to second life scenarios. Decision support systems (DSSs) can be implemented to identify the best second life scenario for...
Due to the growing amount of cooperative business scenarios, collaborative Business Process Management (cBPM) has emerged. The increased number of stakeholders with minor expertise in process modeling leads to a high relevance of model understandability in cBPM contexts. Despite extensive works in the research fields of cBPM and model understandabi...
Sales figures for electric vehicles still lag behind expectations. Most prominently, limited driving ranges, missing charging stations, and high purchase costs make electric vehicles less attractive than gas-operated vehicles. A huge share of these costs is caused by the electric vehicle battery. Since the batteries' performance degrades over use a...
The electric vehicle battery is the crucial component in electric vehicles. It propels the vehicle’s engine and causes around 25 % of the vehicle’s overall costs. Unfortunately, due to deterioration, the battery’s use gradually restricts the vehicle’s driving range, acceleration, and charging speed over time. Only a battery replacement restores the...
Today, two central issues interfere with a widespread use of electric vehicles (EVs): a limited convenience in terms of range and refueling as well as high costs. The expensive battery technology causes the better part of these costs. However, after about 8 to 10 years of operation and 120.000 driven kilometers, battery degradation leads to a reduc...
Mit der Umwidmung und Nachnutzung gebrauchter Batterien aus Elektrofahrzeugen (EV) können die hohen Anschaffungskosten und somit ein Haupthindernis für die Verbreitung von EV adressiert werden. Die Wirtschaftlichkeit ist dabei durch die effiziente unternehmensübergreifende Aufgabenerfüllung und durch rechtliche Auflagen beeinflusst, die durch die C...
A battery management system (BMS) is an embedded system for monitoring and controlling complex battery systems in high-tech goods, such as electric vehicles or military communication devices. BMSs are often designed for simplicity and cost efficiency, storing few crucial data on the condition of batteries. With an increasing trend to reuse batterie...

Electric vehicles (EVs) are considered as a ground-breaking innovation for making transportation services more sustainable. Electric vehicle batteries (EVBs) are the major technological components of electric vehicles and account for up to one third of the EVs' initial price. Due to continued cell degradation, EVBs need to be removed from the EVs a...
Information systems for supporting collaborative activities (e.g., business process modeling tools, workflow management tools, or project management tools) should explicitly address regulatory requirements. Integrating a legal perspective into such information systems would contribute to a better legal compliance and a more effective collaboration....
Increased regulation forces financial companies to assure their business processes’ compliance with legal and company-internal rules. In this paper, we introduce a model-driven business process compliance checking approach. It allows for defining compliance rules and identifying their occurrences in process models based on a graph theory-based appr...
