The electric car will play an important role as a power consumer in the digital energy world. As an energy storage device, the electric car has great potential to drive the energy transition forward and absorb peak loads resulting from regenerative generation. Cars are stationary for most of the day, which leaves a great deal of time for flexible charging. Because of this, the new power consumers not only present an additional load on the power grid, but can potentially serve as flexible storage devices in the context of the variable availability of solar and wind power. Inside a building, electric cars and household appliances, heat pumps, and other consumers can coordinate their particular power requirements, thereby preventing overloads. However, this requires all large power generators and consumers to be connected in order to ensure intelligent control of power requirements. This is precisely what the EEBUS initiative has defined as its goal: Seamless and cross-industry communication in the energy system of the future. Audi is working together with more than 70 international companies to create the common language for energy management in the Internet of Things.
