Although suggestive, the hypothesis of being able to power a car with solar energy has always appeared very optimistic. Like all new technologies, however, this also has potential for development and during today’s conference at CES 2021 the German startup Sono Motors showed the progress made in this field by presenting the renewed Sion and surprisingly a semi-trailer prototype covered with cells solar.
Both the photovoltaic trailer, built together with the Finnish Valoe specialized in the production of solar cells, and the renewed Sion use a new process that replaces the cells for the painting process. Compared to classic glass-based panels, polymers are more versatile, they adapt better to the curved surfaces of vehicles and allow to increase the overall display area and efficiency while also containing weight.
More clean energy
According to Valoe, the trailer is able to generate up to 80 kWh of energy in a day and in ideal exposure conditions, which makes it an ideal support for many applications, not only traction but also the power supply of on-board devices. , equipment or insulated compartments, contributing directly and indirectly to reducing the production of pollutants and CO2.
The Sion also represents the first integration of new solar technology on a vehicle intended for series production. Sono Motors has combined its platform, already equipped with a bidirectional charging system and ready for Vehicle to Grid, on a structure designed to make extensive use of large-scale production components, with the aim of making the car suitable for large-scale production series and with competitive costs.
In addition, connectivity and remote control have been implemented, improve the car’s remote management app that now communicate with the central control system of the propulsion system and with the infotainment. In this, real-time energy monitoring can be achieved, but also functions such as keyless access, opening the charging cover, temperature control and passenger compartment lighting can be realized.
