If the LEAF range is increased to the speculated 180 mile range then you shouldn't need in town charging, and you will need "out there" charging if you want to take advantage of the increased range for road trips.
All current LEAFs will drive about 80-ish miles of REAL WORLD range when at 62mph (100km) ground speed on a level, no wind, hard surface roadway with no heater and a new condition battery at 70F/20C or above temperature.
Here the LEAF official government rated range worldwide:
124 miles = 200km Japan "EPA" rating for 2011-2012
142 miles = 228km Japan "EPA" for 2013
109 miles = 175km UK / Euro 2011-2012
124 miles = 199km UK / Euro 2013-2014
Here the LEAF official government range:
73 miles = EPA-USA 2011-2012 (EPA LA4 "city cycle" @ 19.59mph average, minus 30%)
75 miles = EPA-USA 2013 (EPA "5 cycle", average of 66 EPA miles range for 80% and 84 EPA miles for 100%)
84 miles = EPA-USA 2014 (EPA "5 cycle" test, 100% charge only)
Nissan has thrown out numbers like a bingo parlor for some time. With the impending release of the 2013 LEAF, they were suggesting to the press that a 2013 LEAF might go 250km (155 miles). Of course, the press just laps that up, as do EV advocates and EV consumers sometimes!
The reality is that any current model year LEAF will drive about 80-ish miles of range autonomy at 100km (62mph) on a dry, level, hard surface road with no wind or climate control, and without cabin climate control. The most important detail is the battery must be in like like new condition at 70F / 20C temperature or higher.
How far that a 2017 or later may optionally and actually go is all just speculation.
