Degrade to what extent? I have a 12 year old Nissan Leaf that's lost maybe 25% of its range. Still absolutely usable as a neighborhood car.

A 2013 Nissan Leaf should get 60-75 miles of range (depending on how much of thebattery you use, as well as climate, and other driving conditions). If it got ~80 miles new, it would still get 60 miles now. That might be enough for someone to make a short commute, though unless they have relatively fast charging at home, a 20+ mile commute 5 days a week might be tough to pull off. But most errands would fall well within the existing / remaining range.

  • 50 mile round trip at 3 miles per kWh would be under 20kWh, or 1.6kW for 12 hours, about the same as a plug in heater on max, easily doable in a normal socket let alone a dedicated charge circuit.

I think most testing uses 80% capacity as the cutoff point. Largely because that's when the loss in capacity really slows down.

> neighborhood car

Not familiar with that term, what does it mean? Shared ride? A car for walking distances?

  • Going to work, groceries and so on, the regular stuff.

    If the city was walkable, you would not need such a thing as neighborhood car, you could just use a bike, but apparently as a society at many places we have decided that the cars are the best mode of transportation ever.
