Mobility company Transdev, through its subsidiary Proxiway, which specializes in car sharing, has launched, in partnership with the Toshiba group, an innovative car sharing service using solar energy and quick-charge points in the eco-district of La Confluence, Lyon, France. The project will run for two years until December 2015.
SUNMOOV’, part of the “Lyon Smart Community” demonstration project led jointly by Grand Lyon and Japan’s NEDO (New Energy and Industrial Technology Development Organization), will use carbon-neutral energy and charging stations, which will be fully powered by renewable energy, supplied by the Compagnie Nationale du Rhône.
From the last quarter of 2014, solar energy produced by solar panels installed on buildings in the Confluence district will allow the charging of the entire fleet of SUNMOOV’ vehicles. Such global energy management, realized on the scale of an eco-district, will be a first in France.
Cars used in the SUNMOOV’ service are the Citroen C-Zero, Mitsubishi i-MiEV and Peugeot iOn.
Photovoltaic power generation capacity is strongly influenced by the weather and this can have a major impact on large systems based on solar energy, Toshiba noted. A further challenge is optimizing power charging system management in a car sharing service where demand for vehicles will fluctuate.
Toshiba’s role is to build and maintain the system and its components, including its Solar Power Generation Amount Forecasting System and Charging Schedule Optimization System that optimizes use of renewable energy as an energy source of electric vehicles. This predicts solar power generation capacity on the basis of information from weather forecasts and climate analysis, and combines this information with the status of reservations for EV sharing and data from their electrical systems, to arrive at an optimized allocation of the vehicles to users and optimal control over the electricity charge schedule of each vehicle.
