Abstract: Electric mobility and renewable energy play key roles in the global energy transition. In this context, vehicle-to-grid technology, which enables bidirectional energy flow between electric vehicles and the grid, could make electric vehicles usable as energy storage units, thus supporting grid stability and integration of renewable energy. However, the willingness of electric vehicle owners to participate in vehicle-to-grid contracts remains insufficiently understood, particularly regarding how they respond to specific contract attributes. This paper addresses this gap by conducting a discrete choice experiment to evaluate the preferences of current and potential future German electric vehicle drivers for various vehicle-to-grid contract alternatives. We find that cycle-based remuneration, flexible contract duration, and environmental nudging significantly enhance consumer acceptance. Conversely, a lower guaranteed battery level and longer minimum plug-in durations negatively impact participation. We also test how respondent characteristics influence participation and identify income-dependent preferences, such as lower-income individuals attributing a stronger preference to fixed daily payments than higher-income individuals. Our differentiated őndings may be used to improve contract designs and marketing efforts to address the unique V2G preferences of various user segments.
