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.
Also, considering that the model S is quite heavy compared to most of the other EVs Iâd guess that its average kWh/mile is noticeably higher than the others. Tesla Model S does 3.1 miles per kWh, Nissan Leaf does 3.4 miles per kWh, BMW i3 does 3.7 miles per kWh.Tesla is not that far off from them while being a much bigger and practical car. After all, Tesla Model Sâ rated mpg is right around 90-95 mpge.lso, considering that the model S is quite heavy compared to most of the other EVs Iâd guess that its average kWh/mile is noticeably higher than the others. Tesla Model S does 3.1 miles per kWh, Nissan Leaf does 3.4 miles per kWh, BMW i3 does 3.7 miles per kWh.
