The project consisted on the design and operation of a system for recharging a swappable battery packs of an electric vehicle during a long route. The aim was to ensure that the electric vehicle could make 1000km a day on consecutive days with no longer stops than 30 minutes every battery swap or charge.

First the battery swapping system was designed, based on the battery packs previously designed for other project (more info battery here).

Later a fleet of light assistance trucks of assistance were design and built, those truck were able to transport charged batteries to the point where it was expected the car would exhaust their on-board batteries and then swap discharged on-board batteries for the charged batteries transported on the assistance truck. This means that every truck has a swapping station on board.

Each truck also had the ability to recharge the batteries when driving, so that the car and its service trucks can operate continuously without stopping. This system was successfully used to assist the electric car that took Quionne the Dakar 2015 (more info car here).
