Vehicle-integrated PV for Electrical Commercial Vehicles – »Lade-PV« Project Begins
June 4, 2020
Heavy-load vehicle traffic is responsible for 6 percent of the CO2 emissions in the European Union. Solar electricity generated directly on the vehicle can improve this balance by 5 to 7 percent. In the »Lade-PV« project under the direction of the Fraunhofer Institute for Solar Energy Systems ISE, four industrial companies and two Fraunhofer institutes want to demonstrate the market feasibility of PV applications in the heavy-load transport. The aim is to develop an overall concept that makes the widespread use of integrated PV modules on electrical and other commercial vehicles (over 3.5 tons commercial load) possible.
To manufacture the light-weight VIPV modules in series production, a production concept will developed and the company Sunset Energiekonzept GmbH will accordingly modify its existing production line. The module prototypes will be integrated into the bodies of electrical commercial vehicles by the TBV Kühlfahrzeuge GmbH, a company specializing in the design and production of refrigerated trucks. To connect the solar module into the existing bus systems of the commercial vehicle, power electronic components will be developed, tested and certified for use on the demo vehicle by the project partner M&P motion control and power electronics GmbH. A Framo electrical truck equipped with solar modules will be tested in the daily distribution operation of the Alexander Bürkle GmbH & Co. KG company throughout the Freiburg region.
The Fraunhofer IVI is developing an energy forecasting model for the truck. Dependent on the vehicle load and the PV electricity produced along the various routes, projections are made for the driving range, loading periods and the electricity production.
