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.
Leaf battery packs can be charged from fully discharged to 80% capacity in about 30 minutes using DC fast charging. As of August 2016, the Nissan Leaf is the world's all-time best selling highway-capable all-electric car with more than 233,000 units sold worldwide since 2010.
