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 depends on the type of batteries in the car and it depends on the type of outlet you're using to charge the thing up. Let's take a few real-world examples: - The Nissan LEAF uses lithium-ion batteries, just like your laptop and your cell phone, but it uses a lot more of them.It can charge overnight (8 hours) at a 220/240-volt Nissan charging dock that's installed in your garage.It can also charge at a 110/120-volt outlet, the kind you plug your laptop and cell phone into, but it'll take far, far longer.- The sexy Tesla Roadster uses lithium-ion batteries, too, but the 240-volt Tesla High Power Wall Connector, as they call it, can charge that baby in a mere 3.5 hours. The Nissan LEAF uses lithium-ion batteries, just like your laptop and your cell phone, but it uses a lot more of them.
