French company ARMOR and Gazelle Tech presented a prototype electric vehicle with an automatically unfolding tent-cover with integrated solar panels. This allows you to save money on charging the vehicle while it is parked. According to the calculations eight hours of charging with solar panels should be enough for an additional 30 kilometers.
Electric vehicles are markedly different from conventional cars from a technical point of view, but for owners they primarily differ in the user experience. The most noticeable difference from the vehicle with the internal combustion engine is charging. It is considered one of the major drawbacks of electric vehicles, because it usually takes a long time, although new electric vehicles this disadvantage is not so pronounced, and, for example, Volkswagen ID3 for half an hour is charged at 290 miles.
But getting power from electricity — it is also an opportunity for engineers to develop new methods of charging. For example, in electric in addition to mechanical braking, regenerative braking is applied, allowing to charge the battery while riding. In addition, there are project wireless charging of electric vehicles, and electric cars with solar panels, but their panels are only on the hood and the roof and glass remain unused.
Engineers from companies and Gazelle Tech ARMOR has come up with an alternative to this design in the form of a charging tent-cover that can be deployed after Parking. It consists of fabrics and an array of flexible solar panels, arranged in three lanes the entire length of the awning. The total area of solar panels is four square meters. Awning mounted on two carrying straps connected with both bumpers. After Parking the straps can pull the tent from the rear bumper and quickly enough to pull the whole car.
The prototype made on the basis of the electric Gazelle, which has a power reserve of 180 kilometers. The developers note that in eight hours, solar panels can provide energy, which is enough for 30 kilometers.
It is noteworthy that some electric cars can not only get energy from the grid, but also to give it to earn it. Nissan and Enel conducted tests and showed that this scheme can be successfully applied for load balancing in the network.
