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.
The U.S. Environmental Protection Agency (EPA) official range for the 2016 model year Leaf with the 30 kWh battery is 172 km (107 miles) on a full battery charge, while the trim with the smaller 24 kWh battery is 135 km (84 miles), the same as the 2014/15 model year.
