The EEBUS SPINE communication protocol (Version 1.1.1) for smart EV charging with detailed descriptions of all defined applications are available on the EEBUS website.
With the application cases defined in the EEBUS standard, electric cars and charging stations can interconnect with energy management systems across manufacturer boundaries. The participating manufacturers thus prepare their products for the grid integration of electromobility at an early stage and help to minimize the need for grid expansion. EEBUS positions its model as a bridge between charging infrastructure and Smart Home / Smart Building.
In addition to several large companies, industry associations, especially in Germany, also rely on the communication standard in order to intelligently integrate the energy-relevant products of their industries into decentralised power generation systems and the Smart Grid. Also in building technology, the communication protocol seems to be gaining ground. After TQ-Systems and Hager, the Schneider Electric electrical group is also integrating the EEBUS use cases into its energy management system. “This enables standardized power management at the house connection point,” says Konstantin Elstermann, Head of E- Mobility & Prosumer at Schneider Electric. “It is important that other large consumers such as heating and air-conditioning technology are also included in the energy management system in addition to e-cars.”
EEBUS has been anchored in the heating sector for years. Here, all major manufacturers rely on standardised networking so that heat pumps and electric cars, for example, can coordinate their energy requirements efficiently and safely with storage systems and the power grid.
The EEBUS initiative has been working with the Open Charge Alliance (OCA) since early 2019 to harmonise energy management in e-mobility. While EEBUS standardizes the networking of energy-relevant systems in buildings, OCA has developed OCPP, a standard for networking public charging points and their management systems.
The two organizations exchange their use cases and harmonize the interfaces between their communication protocols. The aim of the cooperation is to integrate smart EV charging points in households, commercial car parks and public spaces into the power grid using uniform technologies. This eliminates the danger of the frequently described “e-mobility blackouts”. On the contrary: electric mobility is thus developing into an important grid-connected component in the future electricity market.
