Volkswagen starts pilot phase for new DC wallbox
The Volkswagen Group Components brand reveals its newest product: the DC wallbox, which charges up to 22 kW. Currently, real operation will be starting at five sites as part of a pilot phase. The goal is to gather practical experience in order to develop the DC wallbox quickly in the direction of series production.
“An extensive and needs-based charging structure is the key to the success of electric vehicles. That is why we are working on various approaches that enable customer-oriented, intelligent and flexible charging. Like our flexible quick charging station and the visionary prototype of a mobile charging robot, the DC wallbox is one of the future innovations of the DC charging family for electric vehicles,” said Mark Möller, head of the Technical Development & Electric Mobility division.
With the new wallbox, electric vehicles can be charged with direct current (DC) up to 22 kW – which is about double the speed of a typical wallbox working with alternating current (AC). In charging technology based on direct current, the electricity flows directly into the lead traction battery, provided that the electric vehicle features a combined charging system (CCS) charging port.
As an innovative detail with prospects for the future, the DC wallbox will already be prepared for bi-directional charging. Thus, power can flow in two directions with the wallbox: the power stored in the lead traction vehicle battery can be returned to the grid, if necessary, thanks to an intelligent charging management.
In order to gather experience with the new product, Volkswagen Group Components has started the pilot phase at its own factory sites in Wolfsburg, Braunschweig, Hannover, Salzgitter and Kassel with 20 DC wallboxes. This also means that the existing charging infrastructure will be expanded at the factory grounds. As the number of electric vehicles increases, the need for charging options also increases within the Volkswagen Group.
