Audi charging hub

Challenge

The basic requirement for this project was that the Audi charging hub should run as autonomously as possible, meaning no manual intervention is required. Nevertheless, a certain flexibility needed to be maintained, which Loxone successfully achieved. In addition to the lighting, access and climate control, an entire multimedia control system was also implemented into the hub. A special feature of the project is the pre-installed visitor counting system, which can be integrated into the Loxone system to monitor the amount of people in the building during the pandemic and the number of customers in the hub. Because the look and feel of the hub was very important to those responsible, EBA-tech had to "hide" the temperature sensors, for example under the tables or behind the pictures. Thanks to the flexibility and expertise of the Loxone Partner, all the above requirements were achieved seamlessly.

Solution

For access control in the hub, a total of 2 NFC Code Touches were installed; one at the entrance to the foyer and another one at the entrance to the VIP area. Customers can open the doors with the code displayed on the charging station. The entire interior and exterior lighting is controlled by the DALI communication point and a total of 3 DALI Extensions from Loxone. This way, different lighting scenes can be called up, one of which is the 'cleaning' lighting, for example. The cleaning crew is detected via the NFC Code Touch and the lighting scene is automatically activated. Another example is the 'event' mode, which has been programmed for special occasions and is activated by touching a button. Coupled with the fire alarm control panel, the lighting is dimmed to 100% in case of fire and the doors open permanently. The control of the optimal room temperature as well as heating and cooling with control of the external producers (heat pump, ventilation system and air conditioner) is done via Modbus TCP. The multimedia control is divided into 2 zones, in which music is played all day. An emergency call button is installed in the WC area that, when pushed, emits a signal tone via the Audioserver and sends a notification in the app to raise awareness and register incidents.

For the customer, the focus was on the design, among other things. It is the first hub of its kind, so they wanted to make the customer experience and the "aha" effect as high as possible. At the same time, neither operator nor customer should feel patronized by the technology, which is also an ironclad principle of EBA-tech.
