CO2-neutral charging thanks to solar power

Garmisch-Partenkirchen showcase project

“sun2car@GAP” – the name says it all. After all, the Garmisch-Partenkirchen showcase project essentially focuses on the usage of renewable energy. The testers use the solar power generated by their home photovoltaic panels to charge the electric vehicles.

Potential for reducing CO2

Together with the Forschungsstelle für Energiewirtschaft e.V. and the Technical University of Munich, Audi is analysing throughout a one-year project phase the usage of electric vehicles which can be charged with as high a proportion of renewable energy as possible. A fleet of Audi A1 e-tron vehicles is being used and tested in parallel with seven conventional Audi A1 and three Audi A3 Sportback g-tron models.

 

The testers are Garmisch-Partenkirchen residents who have already installed photovoltaic panels in their homes. With the aid of “smart wall boxes” they can use the self-generated solar power to charge their Audi A1 e-tron. A process that does not generate any CO2.

Optimisation of the network infrastructure

“sun2car@GAP” is a project that supports the transition to a new energy economy and makes the testers aware of the potential options for CO2-neutral mobility as part of everyday motoring. Important insights for optimising the network infrastructure are also being gathered as part of the showcase project. After all, electromobility poses major challenges with which car makers as well as cities, municipalities and power utilities will have to contend.

 

An important aspect in this respect is the provision of universal charging options for all electric vehicles. A plan which would put a major strain on today’s local power grids in the wake of a substantial increase in electric vehicles. At the same time, local surpluses of power fed into the grid may develop given the high density of photovoltaic panels. “sun2car@GAP” aims to resolve precisely these two problems: a large number of electric vehicles in areas with a high concentration of photovoltaic panels is the ideal way of detecting critical power grid conditions. On the basis of this set-up a simulation tool can be developed which will provide comprehensive figures. All of which represents a major step in promoting the usage and acceptance of electromobility.
