The extension of the program to Indianapolis was announced on Friday.
Customers who purchase or lease a new Leaf beginning on April 1 will receive complimentary charging at nine Ricker's locations, plus three additional stations at Indianapolis-area Simon Property malls.
Ricker's is an Indianapolis-based operator of fuel and convenience stores.
Nissan said this effort represents the "largest city-wide deployment of EV chargers at a chain of fueling stations in the U.S."
Indianapolis is the 14th market in the U.S. where Nissan has launched the "No Charge to Charge" program.
The EV-charging infrastructure in the U.S. is growing on an almost daily basis.
Edmunds says: Car shoppers in Indianapolis get another good reason to consider the Nissan Leaf.
