Solar powered hybrid to cut the cord to the outlet and the pump
Instead of plugging into a wall outlet and using electricity made with fossil fuels, Ford’s C-MAX Solar Energi Concept recharges using solar cells on the vehicle’s roof.
The C-MAX Solar Energi Concept uses a special concentrator that acts like a magnifying glass, directing intense rays to the solar panels on the roof.
The result is a concept vehicle that takes a day's worth of sunlight to deliver the same performance as the conventional C-MAX Energi plug-in hybrid, which draws its power from the electric grid.
Ford C-MAX Energi gets a combined best miles per gallon equivalent in its class, with EPA-estimated 108 MPGe city and 92 MPGe highway, for a combined 100 MPGe. By using renewable power, Ford C-MAX Solar Energi Concept is estimated to reduce the annual greenhouse gas emissions a typical owner would produce by four metric tons.
The C-MAX Solar Energi Concept, will debut at the 2014 International CES in Las Vegas.
Breakthrough clean technology
Researchers developed an off-vehicle solar concentrator that uses a special Fresnel lens to direct sunlight to the solar cells while boosting the impact of the sunlight by a factor of eight. Fresnel is a compact lens originally developed for use in lighthouses. Similar in concept to a magnifying glass, the patent-pending system tracks the sun as it moves from east to west, drawing enough power from the sun through the concentrator each day to equal a four-hour battery charge (8 kilowatts).
With a full charge, Ford C-MAX Solar Energi Concept is estimated to have the same total range as a conventional C-MAX Energi of up to 620 miles, including up to 21 electric-only miles. Additionally, the vehicle still has a charge port, and can be charged by connecting to a charging station via cord and plug so that drivers retain the option to power up via the grid, if desired.
By tapping renewable solar energy with a rooftop solar panel system, C-MAX Solar Energi Concept is not dependent on the traditional electric grid for its battery power. Internal Ford data suggest the sun could power up to 75 percent of all trips made by an average driver in a solar hybrid vehicle. This could be especially important in places where the electric grid is underdeveloped, unreliable or expensive to use.
The positive environmental impact from Ford C-MAX Solar Energi could be significant. It would reduce yearly CO2 and other greenhouse gas emissions from the average U.S. car owner by as much as four metric tons – the equivalent of what a U.S. house produces in four months.
Ford says that if all light-duty vehicles in the United States were to adopt Ford C-MAX Solar Energi Concept technology, annual greenhouse gas emissions could be reduced by approximately 1 billion metric tons.
