The program is now available at Nissan Leaf dealers in 48 markets in the U.S. and is offered to those who buy or lease a new Leaf.
"Since the program kicked off in the summer of 2014, owners have saved over $4.2 million in public-charging fees," said Brian Maragno, director of Nissan electric vehicle sales and marketing, in a statement.
The promotion includes access to fast chargers that can charge a Leaf battery pack from empty to 80 percent in about 30 minutes.
The base 2016 Leaf has a driving range of 84 miles, according to the EPA. The 2016 Leaf SV and SL models with the 30-kWh battery pack have a 107-mile driving range.
Nissan sold 1,063 Leaf electric cars in July, a decline of 9.5 percent versus July 2015, according to the automaker's monthly sales report.
