Lucerne – Two projects at the Lucerne University of Applied Sciences and Arts (HSLU) are investigating how bidirectional charging can be implemented on a larger scale. One project is working with e-fleet operators. The other project explores the conditions for privately used charging stations.
Both for the individual users and for the entire electricity grid, solar power and e-mobility formed a dream couple, writes the HSLU in a statement. Researchers at the university are working on two projects to investigate how the use of e-vehicle batteries for the power grid, known as bidirectional charging, would be feasible on a larger scale. Bidirectional charging not only helps to increase self-consumption, but can also provide control energy for the power grid.
Antonio Papaemmanouil’s project is aimed at this stabilization of the power grid. “Despite progress in pilot projects around the world, there are still gaps when it comes to implementing solutions,” the head of the Institute of Electrical Engineering at HSLU is quoted as saying in the release. In their research for the optimal integration of electromobility into existing energy systems, the researchers in Papaemmanouil’s group are working with operators of e-fleets.
Roger Buser’s project investigates what conditions must be met in order to attract enough private individuals for bilateral loading. Such charging stations are currently still “up to five times more expensive than a conventional one,” explains the expert for solar energy at HSLU. According to his group’s research, potential users also expect an easy-to-use system in which a discharge limit can be set. A guarantee against shorter battery life is also on the wish list. The researchers themselves cite standardized interfaces for the integration of charging stations as a necessary prerequisite. ce/hs
