ComfficientShare
Comfortable and efficient electric vehicle and charge point sharing for residential districts.
TEST SITE SELECTED
Among several suitable site candidates, we chose a residential neighborhood in Nymphenburg based on technical requirements and residents' interest in our project.
PARTICIPANTS FOUND
In July, we held an information evening on site in our residential neighborhood in Nymphenburg. As a result, we were able to convince nine households to participate in our project.
START PHASE 1: INITIAL MOBILITY BEHAVIOR RECORDING
Our first trial phase started at the end of September. In this phase, we installed a GPS receiver in all of our participants' private cars, which permanently records the vehicles' movements.
MILESTONE 1
Finally, the time had come - the MCube Cluster was able to meet with all employees and partners for the first time in presence above the roofs of Munich in the beautiful Vorhoelzer Forum of the TUM.
PARTICIPANTS SELECTED FOR PHASE 2
Based on the recorded mobility behavior and with the goal of obtaining as diverse a group of people as possible, we selected five households.
These will each receive an electric vehicle for the second testing period.
START PHASE 2: ELECTRIC VEHICLES HANDED OVER
Shortly before Christmas, we selected five households which each received an electric vehicle in the second trial phase. They will now use them privately for the next few months in exchange for their combustion engine.

WHAT HAVE WE DONE
We have tested an innovative car-sharing model with electric vehicles in a real-world laboratory. The special feature: Only a closed circle of neighbors shared the cars.
HOW DID WE DO IT?
Over a period of 18 months, we provided five electric cars in the underground parking garage of a block of flats. The participants were able to use the vehicles free of charge, with the exception of charging costs. In return, they undertook to refrain from using their private vehicles during the project. Thanks to the small user group, the comfort of the private car was maintained while the vehicles were used more efficiently.
WHY DID WE DO IT?
In Munich, many cars are rarely moved, while parking spaces are scarce. Our "ComfficientShare" project investigated whether this car-sharing model offers a practical alternative to owning a car. The aim was to reduce the number of vehicles without compromising convenience. At the same time, we investigated how the integration of electric vehicles into the power grid can help to reduce energy costs and smooth out peak loads.
WHERE DID WE DO IT?
The real laboratory took place in a block of flats with over 280 residential units in Munich-Nymphenburg. The apartment block belongs to the Gemeinnütziger Wohnungsverein München 1899 e.V., with whom we worked closely.
