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.
However, how long you wait depends on the type of charging station or plug that you are using. Level 1 charging plugs are basically your everyday household outlets. For a Nissan Leaf which has a range of approximately 100 miles, this may mean over 22 hours of charging to reach full charge. But the fact of the matter is that you will rarely need your car to be at full charge. For an average American who travels 40 miles per day, a 9 hour charging stretch is enough for a normal amount of commuting the next day. Level 1 charging is perfect for cars like the Chevrolet Volt which is a plug-in hybrid with a 40 mile electric range. Overnight charging will result in full charge for this EV. With voltage of 110 V, a typical sedan will take about 20 hours to charge fully, if needed.
