FLEXGRID Research project: PRE Develops a V2H charger module for DC smart home

Now that we have completed the award winning 'solar powered V2G EV charger' research project, it is time for the next phase: The FLEXGRID project. The goal of the FLEXGRID project is to enable operational flexibility of distribution networks using residential energy storage and demand. For this project PRE will develop a multiport converter with multi-directional power flow, enabling vehicle2home (V2H charging) and battery2home. With the multiport technology we are able to charge both the EV and the home battery as well as control the energy between the batteries. This will enable a whole new way of 'home charging'. For example with less sunny days you can charge the home battery with your EV. This converter is acting as the electric heart of the DC smart home.

The higher participation of decentralized generation and storage devices working on DC, like photovoltaic cells, fuel cells, batteries, and electric vehicles, brings new opportunities for the built environment. Connecting DC sources and storage via a DC network lowers investment costs and increases efficiency.
Besides the converter also a power and energy management system will be developed, that will optimize the use of storage, appliances, and renewable energy. In this way, the project will facilitate the introduction of efficient low-voltage DC networks for smart buildings.

Together with Alfen, Stedin and Delft University of Technology, PRE power developers participates in the FLEXGRID Research project (A TKI Urban Energy Project).
PRE will inform the market about this project on Facebook and LinkedIn.
