Ten years ago, Nissan was selling a lithium-battery-powered car in Japan
called the Hypermini. With lessons learned, the Leaf's batteries have
twice the energy density (the battery power is rated at over 90 kw, with
a capacity of 24 kilowatt-hours) and are less expensive to produce,
thanks to the use of manganese electrodes. Using a single-phase
200-volt, 15-amp power supply, the batteries can be fully charged within
eight hours using a 220-volt outlet, or about twice as long if you plug
into 110. Using a three-phase, quick-charging station, the Leaf can
attain an 80 percent charge in just 30 minutes.
