In magnetic resonance, the time for 63% of transverse relaxation to occur; the value is a function of magnetic field strength and the chemical environment of the hydrogen nucleus; for protons in fat and in water, in a 1.5T magnet, about 60 milliseconds and 250 milliseconds, respectively.he effective T2 relaxation time, shorter than T2 because of magnetic field inhomogeneities; the observed time constant of free induction decay.
Including conversion and generation losses, a single full Leaf charge might take 25 kWh (19 kWh usable into the battery). Factor in expected usage to get an average kWh per month value.
First is the cost per hour to use the charging station. Second is the number of miles of range the car gets per hour of charging. The electric cars with a 3.3 kilowatt on-board charger (Nissan Leaf, Chevy Volt and Mitsubishi iMiev) typically get 12 miles of range per hour hour of charging.
