  2. Electronvolt - Wikipedia

    en.wikipedia.org/wiki/Electronvolt

    It is common in particle physics, where units of mass and energy are often interchanged, to express mass in units of eV/c 2, where c is the speed of light in vacuum (from E = mc 2). It is common to informally express mass in terms of eV as a unit of mass, effectively using a system of natural units with c set to 1. [3] The kilogram equivalent ...

  3. EV Range: Everything You Need to Know - AOL

    www.aol.com/ev-range-everything-know-132000750.html

    We explain EPA ratings, factors affecting range, how EVs performed in our testing, and why it's all complicated and different from the gas-powered-vehicle norm.

  4. Exposure value - Wikipedia

    en.wikipedia.org/wiki/Exposure_value

    An increase in exposure corresponds to a decrease in EV, so an exposure compensation of +1 EV results in a smaller EV; conversely, an exposure compensation of −1 EV results in a greater EV. For example, if a meter reading of a lighter-than-normal subject indicates EV 16, and an exposure compensation of +1 EV is applied to render the subject ...

    The actual all-electric range is between 0 to 16 mi. [106] Gasoline only: 35 mpg-$1.79 BMW i8 [92] [109] 2014 2015 2016: Electricity and gasoline (15 mi) 76 mpg-e (43 kWh/100 mi)-$1.77: $1,150: The i8 does not run on 100% electricity as it consumes 0.1 gallons per 100 mi in EV mode (all-electric range = 0 mi) The i8 has a rating for combined EV ...

  6. Electric cars in winter: How cold weather affects EV range ...

    Electric cars perform less well in cold weather. Lower ambient temperatures affect an EV’s range, but also how quickly the battery charges and how effective its regenerative braking system works ...

  7. EV Highway Range Can Be Very Different from the EPA Numbers - AOL

    www.aol.com/ev-highway-range-very-different...

    Still, new EV shoppers worry about it. Range matters mainly if you travel long distances, and it's only one factor on a long list that includes performance. Still, new EV shoppers worry about it. ...

  8. Photon energy - Wikipedia

    en.wikipedia.org/wiki/Photon_energy

    Photon energy is often measured in electronvolts. One electronvolt (eV) is exactly 1.602 176 634 × 10 −19 J ‍ [3] or, using the atto prefix, 0.160 217 6634 aJ, in the SI system. To find the photon energy in electronvolt using the wavelength in micrometres, the equation is approximately

  9. Does an EV Work as Well in Cold Weather?

    www.aol.com/does-ev-well-cold-weather-151000410.html

    EV Range Is a Little Lower in Cold Temperatures. Electric-car batteries are like humans; they like to be around 70 degrees F. When temperatures fall, the battery’s performance degrades, and the ...
