So far, the electricity in electromobility has mainly flowed in one direction - from the charging point to the vehicle. This could soon change in the course of vehicle-to-grid applications (“from vehicle to grid”). In the future, electric cars could also feed energy back into the public power grid when they are not being driven. Combined into a pool of numerous vehicles, these could supply part of the so-called balancing power as a virtual power plant. This balances out the fluctuations in the power grid.
A realistic pilot test by Porsche, the transmission system operator TransnetBW and the consulting firm Intelligent Energy System Services (IE2S) has now shown that the high-voltage batteries of electric cars can buffer the electricity as an intelligent swarm. Five production Taycans were connected to the power grid via the Porsche Home Energy Manager (HEM) both in a home environment and under laboratory conditions. Experts from Porsche Engineering had previously adapted the software for these control centers to the field test.
