• Drive segments lines at 40, 60, and 80 mph intersect at zero with the charge curve.
  • Limited to 3 hours (180 minutes) of driving
  • Maximum 30 minutes of charging in 10, 20, and 30 minutes

A horizontal line from one of the three speed lines to the charge curve gives the total minutes for one driving segment, the sum of driving time and charging time. For example, driving at 80 mph for an hour:

• -60 minutes to drive 80 mph
• +8 minutes to charge for that distance at that speed
• 60 + 8 = 68 minutes for that segment
• 80 mi * (60 / 68) = 70.6 mph equivalent speed combined driving and charging

Driving at 80 mph for an hour with required charging, the block-to-block speed will at best be 70 mph or 70 / 80 = 87.5% of the EV driving speed. This leads to a more useful summary chart.

Here is a chart of block-to-block, speed...

Nissan is producing a motor using an electro-magnet rotor which eliminates the need for permanent magnets:


The same as running an alternator as a motor, this is a brilliant solution as it also solves the problem of back-EMF that requires 'field weakening' in traditional motors. There is no free lunch as the rotor coils require power but the dynamic range of efficient power production is well worth it.
