Gallery: Solar Filling Stations: On-Demand Fuel for Electric Cars and B...

emove, solar, solar power, energy

The problem with grid-powered electric cars, bikes, and scooters is that you never know what’s supplying their energy. Is it coal, solar, nuclear, or some combination of the three? Enter the E-Move Charging Station, a  solar-powered filling station in Bozen, Denmark that can charge up to eight vehicles at the same time. With the E-Move station, you’ll always know where your vehicles power is coming from – the sun!

The prototype station, designed by Valentin Runggaldier, consists of eight mono-crystalline solar panels. The panels produce a total of 1.76 kWp of solar energy, and Runggaldier predicts that the station can generate up to 2,000 kWh over the course of a year. No word on how long the filling stations require to charge different devices, but unless people have the capacity to wait all day while a plug-in car is charged, the stations might be best suited for smaller devices.

Runggaldier’s Bozen station is just the first in what is likely to be a series of solar-powered charging docks located throughout Europe. If all goes well with the test model, Runggaldier plans to sell his station to local governments, private companies, and car rental agencies. The owners of the filling stations will dole out solar power only when consumers pay by cell phone or credit card.

    I love this concept…using renewable energy to make electric cars zero emission.

    But this charging point is too small to be effective for charging vehicles. To put it in perspective, with a gasoline car you can fill up your tank with 40-liters of gasoline in about 2 minutes. The rate that energy is flowing into the car is 11.55 MegaWatts. With 40-liters of gasoline you have put 1,386,400 kJ of energy onboard.

    To store the same amount of energy in a battery at a rate of 1.76-kW would take 218 hours or roughly 9 days.

    But all is not lost. Electric motors are very efficient, and electric cars like the one shown are light and don’t go at high speed. These cars would not need to store the same energy as 40-liters of gasoline, and the charging time would be less. But it would still take a long time to charge with this device. It simply needs more solar panel area.

    Charging stations like this are more for peace of mind and a maintenance charge that will add a bit to the car or let you use your laptop without draining the battery while you are shopping, at the beach or at work. Think about it realistically for the car, I’d be happy if it can provide even 10 minutes of extended drive time from solar power.

    If people know these things are out there, they might reconsider where they can go and not be so afraid to drive a bit father from home in their EVs. They know they can get the extra charge to make it back even if they had enough to begin with.

    I tried a while back to get some statistics on EV draining cycles from Slashdot. No one responded. So the situation we have is people just don’t know how an EV is going to behave in that last 10% or 5% of it’s charge. I’d love to see some stats on what the cars do to warn the driver, how soon they warn, if the distance the car predicts actually is attainable, etc.

    This is in Italy, not Denmark.

    You mean Bozen, ITALY…

    Bozen (Bolzano) is in South Tyrol, Northern Italy.
