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.
It seems Nissanâs engineers were up for that challenge though, as the Leaf is an exceptional vehicle â one that could turn the tide for all-electric cars in the U.S. The 2012 Leaf is powered by an 80-kW AC synchronous electric motor, and stores its energy in a 24-kWh lithium-ion battery pack. That equipment grants it a real-world driving range of 70 to 100 miles on a full charge.
