Intermediary report on the study “bidirectional charging – use cases from the user’s point of view” commissioned by ADAC online

Up to now, bidirectional charging has been seen mainly as a technological challenge and has therefore been driven forward in particular by industry and power grid operators. As the technology continues to mature, the benefits and risks for the end users of bidirectional charging are now coming to the front. After all, they are the ones who have the crucial element in the system: the electric vehicle with its battery. Only with a high level of customer acceptance will bidirectional charging become widely accepted and thus be able to realize its full potential for grid stabilization and generation flexibility in an increasingly volatile electricity system.

A quick introduction to the technology of bidirectional charging

The interim report on the study ” bidirectional charging – use cases from the user’s point of view” provides a quick introduction to the topic by explaining the possible applications for bidirectional charging that are relevant in the short and medium term. It presents the current state of the art and summarizes the key points. Users of electric vehicles are provided with an initial orientation on the potential revenue to be generated by bidirectional charging. In the interim report, decision-makers in politics and industry will find initial recommendations for action to make bidirectional charging attractive for users and thus stimulate a broad market ramp-up.

The presented interim results of the study include profiles of all use cases investigated in the study that are made possible by bidirectional charging. In addition, for a selected use case – PV self-consumption optimization – they already provide a detailed insight into the simulations that were created at FfE with the institute’s own model eFlame.

Recommendations for decision makers and tips for consumers

As a special highlight, the interim report offers valuable recommendations for action for decision-makers as well as tips for all interested users that answer the question: “What should I be aware of if I want to switch to bidirectional charging technology in the future?”
