EP Tender

EP Tender is a range extender for electric vehicles unlocking affordable and convenient long-distance travel


Customers can rent a light trailer on-demand, immediately adding a further 60 kWh capacity to their vehicle, without impacting its payload.

Incredibly versatile, Tenders – as the light trailers are known - are powered by battery, hydrogen, inductive road or gasoline, depending on infrastructure and available technologies. They are attached by a tow bar installed on vehicles. Users are able to book a Tender in advance and pick it up on the day they need it just before they join the motorway. Once they get close to their final destination, the user simply drops it at another rental point.
