Audi promotes EEBUS standard for intelligent connection of electric cars and buildings

EEBUS was tested at the Plugfest E-Mobility

Audi is involved in the EEBUS initiative to promote networking across manufacturer and industry boundaries. The Audi e-tron is the first electric car whose charging system uses the new communication standard. At Plugfest E-Mobility, developers are testing cross-industry compatibility before the EEBUS standard for energy communication is introduced in February.

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.

During the two-day Plugfest E-Mobility event on January 28-29, EEBUS members will test their developments on the basis of the open communication standard at the Audi plant in Brussels.

Developers and engineers will perform model tests to check whether the photovoltaics system, the charging infrastructure, the electric car, and the heating system can communicate without interference.

The devices are connected via what is known as a home energy management system (HEMS). All the information runs together in this control centre, which allows all energy-relevant devices to exchange information on their electricity requirements. Following the Plugfest, the companies involved will pass the EEBUS specification for the area of e-mobility.
