The Porsche Taycan as a buffer for the power grid

In the future, electric cars that do not drive could feed energy back into the public electricity grid and act as a power station. They would thus help to provide what is called balancing energy, an electrical energy that balances the fluctuations of the electrical network.

A realistic pilot test conducted by Porsche, grid operator TransnetBW and consultancy firm Intelligent Energy System Services (IE2S), demonstrated that electric balancing energy could be stored in the high-voltage batteries of an intelligent fleet of electric cars. For this purpose, five production Taycans were connected to the power grid via the Porsche Home Energy Manager (HEM), both in a domestic environment and under laboratory conditions.

Increase acceptance of e-mobility

“The charging technology of the Porsche Taycan and our Home Energy Manager and Mobile Charger products have a lot of potential for the future: the pilot test has proven this. The balancing energy market is by the way not the only thing for which a pooling system of this type can be used,” said Lutz Meschke, Deputy Chairman of the Board of Directors of Porsche AG. “Advanced solutions for green charging and other vehicle-to-grid applications are also conceivable. But that’s not all: if electric vehicles feed energy back into the electricity grid in the future, for example with a private photovoltaic system contributing to the expansion of regenerative energy, this will further increase acceptance. of e-mobility. “To think that not so long ago we were still talking about the fear of the lack of autonomy…
