Sono Motors cooperates with Chereau

Together, the companies want to equip the cooling of truck trailers with solar technology. They want to present a first prototype this year.

Sono Motors is best known for its solar-powered car Sion. However, the Munich-based start-up's solar technology can also be used for other vehicles - such as refrigerated trailers. Together with Chereau, the French subsidiary of The Reefer Group, Sono Motors now wants to equip these refrigerated trailers for trucks with solar technology.

According to the start-up's calculations, solar cells could supply the refrigerated trailers with an additional 9.8 kilowatt peak. This would save about 3,400 liters of fuel, since the refrigeration is normally diesel-powered. Per year, transport companies could save about nine tons of CO2 per vehicle with the solar refrigerated trailers. If the start-up's calculation works out, the transport of frozen food, fast food and medical products would become more sustainable. Although the production of the solar trailer also causes emissions of around 6.5 tons of CO2, these are already offset after a runtime of less than one year.

To test the technology, Sono Motors wants to equip the roof and sides of a Chereau refrigerated trailer with solar modules. These are to cover a total area of 58.9 square meters. The two companies plan to unveil the prototype at the IAA Transportation show in Hanover later this year. After that, Chereau and Sono Motors would like to test the first trailer in a field trial lasting several months at a customer's site in France to verify the CO2 savings figures, for example.

"This partnership is a big step for Sono Motors as it opens up a whole new industry for the use of our extremely flexible, proprietary Sono Solar technology," says Sono Motors co-founder and CEO Laurin Hahn. "We offer a lightweight and customizable platform that is ideal for use in refrigerated trailers." The collaboration with Chereau is the 17th partnership for the startup. Other partners include MAN, Easymile and Münchner Verkehrsgesellschaft.
