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.
Typically itâs eight years, and mileage is usually at least 100,000 miles. Tesla warranties its 60-kwh Model S to 125,000 miles, and the 85-kwh version gets unlimited miles. Nissan warrants the Leafâs battery against defects for 8 years/100,000 miles. It projects its life for at least 10 years, with the expectation that youâd have around 60-70 percent battery life at that point, depending on usage patterns.
