V2Heff – Increasing the energy and cost efficiency of Vehicle to Home Solutions

With the increasing spread of photovoltaics and electromobility, bidirectional charging of electric vehicles is becoming more and more important. Especially in single-family homes, the implementation of vehicle-to-home (V2H) is much simpler and less complicated than vehicle-to-grid or feeding energy back into larger buildings.

Due to the usually very low back feed power, specific questions arise regarding efficiency and losses, which have not yet been systematically investigated. Initial findings indicate that first-generation V2H applications have considerable potential for increasing efficiency. This project aims to investigate this potential through measurements.

Based on the findings, a concept will be developed that significantly increases the efficiency of V2H. The feasibility of this concept will be demonstrated in an initial laboratory prototype.

The project is funded by the Swiss Federal Office of Energy as part of the mobility research program. The scientific partners are the Institute of Energy Technology (IET) at OST and Bern University of Applied Sciences.
