The new EnBW charging park in Lichtenau near Chemnitz is a new addition to the EnBW Hypernetz, one of the largest fast-charging networks in Germany. Another new feature is the use of wood as the primary roof construction.
Timber construction meets electromobility
The wooden roof structure of the loading bay measures 24 x 12 m and consists of rafters, purlins and A-frames. The trestles were pre-assembled at the factory, including cross-laminated timber panels with screw-press bonding and 1,500 mm long glued-in threaded rods for load transfer from the cross purlins above.
Pre-assembly of the steel parts of the column bases with millimeter precision was necessary to ensure the connection to the 16 individual steel bolts cast in on site.
The wooden rafters were covered on site with steel profiles for the subsequently installed photovoltaic system. The photovoltaic system installed on the roof of the charging park directly generates part of the electricity for the electric cars, which can be charged at 16 HPC (High Power Charging) points under the roof and at 8 other points on site. If required, the charging park can be expanded to 32 HPC charging points with a charging capacity of 400 kilowatts each in the future.
HESS TIMBER was responsible for an extended range of services for this project. In addition to the timber construction, this also included the photovoltaic system and its electrical installation as well as the parapet cladding and the illuminated advertising. The HASSLACHER Group supplied around 1 m³ of cross-laminated timber, 21 m² of three-layer panels and 27 m³ of glulam for each fast-charging park.
