Another success story is the Elways project in Sweden. The purpose was to demonstrate a smart road system for charging electric vehicles, including electric trucks. Today this system is operational in the Stockholm area. e-Traction has integrated their in-wheel motor system and has ‘electrified’ a complete truck based on a DAF LF and performed the complete integration with the necessary systems.

Based on a VDL Citea platform, e-Traction and VDL have built a full electric bus for Stadtwerke Münster in Germany. Full integration of the in-wheel motor technology has been performed and in addition, e-Traction system technology was used for energy management and charging. After the successful demonstration, Stadtwerke Münster now has several buses running with more to come.
