Solar filling station opened in Bozen - DETAIL.de - Green - sustainable planning and co... - 0 views

  •  
    1.7 kWp, 2000kWh per year. How many cars per annum can you charge at, say, 5KWh each? Better stick to bicycles and phones!
  •  
    South Tyrol gets serious about solar mobility: The "E-Move Charging Station", a pilot project of the Bozen entrepreneur Valentin Runggaldier, is to supply electrically operated bicycles, scooters, cars and even mobile phones with the necessary "fuel" from the sun. The solar charging stations were designed by Michael Scherer from Brixen

Google revs up smart charging for plug-ins | Green Tech - CNET News - 0 views

  •  
    There is some concern that millions of plug-in electric vehicles charging at the peak times, such as around 5:30 p.m. when people return from work, could cause power disruptions or require construction of new power plants. To address this, Google has written software with "vehicle dispatch algorithms" that can decide how to best charge cars, Reicher said. In addition to smoothing out the load on the grid, smart charging makes it easier to take advantage of solar and wind power, which are variable sources of electricity.

Ford's EV Charging System Allows Driving Using Only Renewable Energy | CleanTechies Blo... - 0 views

  • Ford Motor Company has developed an intelligent charging system that previews how its production vehicles will interact with the grid. The unnamed system enables all-electric and plug-in hybrid vehicle owners to restrict charging to when electricity prices fall below a certain threshold, or even “when the grid is using only renewable energy such as wind or solar power,” according to Ford.

IDTechEx Predicts Electric Vehicle Charging Going Zero-Emission, Off-Grid - 5 views

  • The new IDTechEx report, "Zero-Emission Electric Vehicle Charging: Off-Grid 2020-2040" examines how the electric vehicle business is finding it profitable to respond to criticism that clean vehicles should not be charged with fossil fuel electricity. The purpose of this 230-page report is to enable materials, component, vehicle and infrastructure suppliers and putative suppliers, and all others in the value chain, to understand this large emerging opportunity for off-grid zero-emission OGZE charging of electric vehicles land, water and airborne.

New energy storage device charges ahead - 0 views

  •  
    Rubloff and his colleagues have developed an energy storage device that improves on the performance of electrostatic capacitors - a device that stores energy as electric charge. The tiny capacitors consist of a layered structure of metal-insulator-metal thin films. The devices are fabricated in massive arrays using minute holes at a density of 60 billion per square inch.

  • (The Volt will be a ful-sized four-passenger car with a range of about 65 kilometres using only its batteries. It is scheduled to go into production in the United States in 2010.)
  • The Volt will use a battery with a capacity of 16 kilowatt-hours of charge. But that battery won’t dip below eight kWh of charge, so a full nightly charge would be eight kWh - about the same amount of power as is consumed by a water heater, a plasma TV or a computer and monitor left on all day.

Electric Bus Charges Wirelessly?! | EcoGeek - 0 views

  • oyota's heavy duty division, Hino, is testing a new kind of plug-in hybrd...one without a plug. The batteries on the hybrid assist and even sometimes take over for the diesel engine. But the energy in the batteries doesn't come from a plug, it comes from a wireless charging system built into the road.
  •  
    Hino, Toyota's truck division, is experimenting with wireless charging. In spite of inefficiences that may exist, Hino should be applauded for pushing the envelope. However, unfortunately for the future, it seems logical that only larger sponsors such as Toyota can afford this type of approach.

Making "Renewable" Viable: Drexel Engineers Develop New Technology for Grid-Level Elect... - 0 views

  •  
    "The team's research yielded a novel solution that combines the strengths of batteries and supercapacitors while also negating the scalability problem. The "electrochemical flow capacitor" (EFC) consists of an electrochemical cell connected to two external electrolyte reservoirs - a design similar to existing redox flow batteries which are used in electrical vehicles. This technology is unique because it uses small carbon particles suspended in the electrolyte liquid to create a slurry of particles that can carry an electric charge."

In Gaza, electric cars offer a way around Israel's blockade - 0 views

  •  
    Palestinian engineers say it only costs $1.50 per fill-up. Israel is also going electric with hundreds of charging stations to be installed nationwide
  •  
    After Portugal, it appears that Israel is the second country to develop a network of charging stations.

Railway Gazette: UltraCaps win out in energy storage - 0 views

  •  
    REGENERATIVE BRAKING is widely practised, but there have to be other trains around to absorb the surplus power being fed back into the catenary or third rail. Processing the output from trains and pushing it back into the local grid is possible with an AC power supply, but very expensive with DC traction. Too often, power produced by traction motors in braking mode ends up heating resistor banks. The elegant alternative is to store the braking energy on the train. This not only avoids the electrical complications of regenerating through the traction power supply network. It reduces the rated power requirement of that network by lopping demand peaks during acceleration, saves energy by reducing losses in the catenary or conductor rail, and by limiting voltage drop it allows substations to be further apart. NiMH batteries have the necessary energy storage density in terms of kWh/kg, and are slightly more expensive, but their life in terms of charge/discharge cycles in no way matches the LRV requirement for 2million cycles over 10 years. Flywheels have been tried but never caught on for several reasons.

The Energy Blog: Subaru G4e Boasts New Battery - 0 views

  •  
    Subaru has released a second generation battery-electric vehicle, the G4e (for "Good 4 earth"). The 5-seater has a maintenance-free 65-kilowatt electric motor, and features high energy-density vanadium enhanced lithium-ion batteries, which give the G4e a 124 mile (200km) range from a charge (more than double the first generation R1e's range, previous post) and using a quick-charger it can be charged to 80% in only 15 minutes

France's First Hybrid Train Hits the Rails | EcoGeek | Hybrid, Train, Electric, Diesel,... - 0 views

  • A hybrid electric train built by Bombardier just took its inaugural trip in France. Diesel locomotives have always been a kind of hybrid -- their diesel engines charge batteries which power a gigantic electric motor. But this new train can run on electric power from any source available (not just the engine.) The trains will be charged with grid power, and will produce roughly 20% less CO2 than non-hybrid versions.
