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 cost of charging a Nissan LEAF in the UK varies depending on the location and speed of the charger, but charging at home is the most cost-effective way to charge and many public charging points are free to use. Charging at home costs as little as 2p per mile: 1  Typical overnight electricity rate of 10p per kWh. 2  Charging a Nissan LEAF therefore costs only 2p per mile.  Based on an average 20 mile daily commute, this equates to only 40p per day.
