KNX aims at electric vehicle charging
European building automation protocol developer KNX is looking to extend its technology into electric vehicles and charging systems
As a technical ISO standard for building automation, KNX enables the integration of charging stations for electric vehicles into the energy management of smart buildings..
The basis for this is KNX technology for an optimal, secure interaction of all devices, installations and charging stations in smart homes and buildings, as well as the ETS tool for smooth configuration and commissioning. The solutions based on these KNX technologies include “SMART CONNECT KNX e-charge II” from ise and “EibPC²” from Enertex Bayern, both in Germany. These systems allow customers to use their own sources of power generation such as photovoltaic systems for charging electric vehicles by intelligently integrating the charging stations into the KNX energy management system of the smart home or building. Up to five different charging points from various manufacturers can be connected to the same system.

The charging current and charging processes are managed in a manner which considers the current electricity consumption so that other running devices and installations in the building, such as the washing machine, oven or air conditioning, are not impaired. It is also possible to prioritise certain charging points so that the vehicle that is needed promptly is charged as quickly as possible. Even weather data and forecasts can be included in the control of the charging processes. If less energy is available due to weather conditions or during the night via photovoltaic systems, the charging processes are regulated accordingly so that no additional electricity has to be obtained from the regional electricity provider.
“In addition to electrified vehicles and charging stations, technologies that enable e-mobility to be safely, easily and, above all, seamlessly integrated into existing infrastructures and thus our everyday life are also decisive for its success,” said Franz Kammerl, President of the KNX Association. “In this respect, KNX is a key player in the field of smart homes and buildings and provides the technological foundation for using electromobility effectively for climate protection by combining power generation from renewable sources with intelligent energy management and the connection of charging stations from various manufacturers.”
KNX is already used for applications in home and building control, ranging from lighting and blind control to various security systems, heating, ventilation, air conditioning, monitoring, alarming, water control, energy management, smart metering as well as household appliances, audio/video and many more. KNX provides a single, manufacturer independent design and commissioning tool (ETS), with a complete set of supported communication media (TP, PL, RF and IP) as well as a complete set of supported configuration modes (system and easy mode).
KNX is approved as a European (CENELEC EN 50090 and EN ISO 22510) and an International standard (ISO/IEC 14543-3) with over 500 member companies worldwide having more than 8,000 KNX certified product groups. The KNX Association has partnership agreements with nearly 100,000 installation companies in 190 countries.
