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.
Average overnight electricity rate is 10p per kWh, which means charging your car for as little as 2p per mile. Fully charging a 30kW Nissan LEAF will cost about Â£3.00 and give you about 150 miles of range. Based on an average 20 mile daily commute, this equates to only 40p per day.
