Though "fueling" an EV costs a pittance next to a gas-guzzler, hunting for that next compatible charging network can bring on cold sweats. Nissan Leaf buyers in 25 markets will soon be able to relax, though. A new "EZ-Charge" card will grant two years of free charging across four major networks: ChargePoint, Blink, AeroVironment and NRG's eVGO. The automaker may have been motivated by its free charging trials in Texas, which led to a three-fold Leaf sales increase at one dealership. The expanded program will roll out to owners in 10 markets this July, provided they bought their Leaf after April 1st. There are other restrictions too: just one hour max of free charging at a Level 2 station and a half hour on a fast charger. The latter option will give an 80 percent charge, but a Level 2 station will only dole out 20 miles' worth of electrons in an hour -- so plan accordingly.
