— We would like to officially announce our “connection” once again –
No, this is not a wedding announcement, although the relationship will be similarly complex. What is meant is the connection of our vehicle to a charging connection.
At first glance, the connection refers to a simple plug on a standard household power cable. However, this cable is connected to a charging system which, in addition to the efficient conversion process from single-phase alternating current or three-phase three-phase current into regulated direct current for charging the traction battery, must also be able to communicate perfectly with a monitoring battery management system and a communicating charging station. At the same time, it had to be small, light and robust enough to spend its highly exciting existence inconspicuously and reliably in the TWIKE 5’s technical compartment.
The bidirectional charging technology from Ambibox GmbH in Mainz, Rhineland-Palatinate, impressively masters all these tasks and more. Their technology not only enables AC charging with 22 kW and a DC fast-charging function via CCS. It also has a direct AC output in the form of a CEE socket integrated in the vehicle with 11 kW and a Schuko socket with 3.5 kW to feed energy from the vehicle’s traction battery back into the owner’s home or for other consumers.
Ambibox and TWIKE are turning the buzzwords Vehicle to Grid (V2G) or Vehicle to Home (V2H) into reality, starting with the exclusive series of the TWIKE 5. Ambibox GmbH acted as development partner and integrated its bidirectional DC charger into the vehicle architecture of the TWIKE 5. Ambibox’s SiC-based power electronic platform can thus be used as a highly efficient on-board charger.
TWIKE pilots thus become entrepreneurs in the field of renewable energies and sustainability. They use their TWIKE like a boy scout uses his Swiss Army knife. It was foreseeable that the new TWIKE 5 would have to offer additional customer benefits by also being an energy storage system for their own household and thus also the public grid. We are very happy to have gained Ambibox as a reliable partner.
