This past Sunday, the New York Times had a piece by Bradley Berman about owners of the Nissan Leaf and how, as with the Prius, there is a growing community of Leaf hackers who are making improvements to their cars and some who are developing products around some of these hacks.
Using the car’s diagnostic service port to tap into its electronics, Mr. Giddings devised a way to display far more detail than the Leaf’s dashboard offers. The car’s electronics monitor the remaining battery charge in great detail, but display it to the driver in a simplified readout of 12 bars on the dashboard, he said.
Using Mr. Giddings’s home-brewed E.V. fuel-level display, Leaf drivers get the confidence to extend their driving range by 10 percent or more. His gauge, which displays the actual state of charge, reveals that the Leaf dashboard’s “zero bars” display comes on when the battery pack has several miles remaining.
“Until you can find out how much is really left in the batteries toward the end of its range, it’s just a guess-o-meter,” said Mr. Giddings, who has sold a handful of his displays, both as $170 kits and as $280 completed units, to Leaf owners.
The piece mentions Leaf hacking groups, at least ten in the United States, but doesn’t give any links or details. You can find many of these groups, and individual Leaf hackers, on the My Nissan Leaf forums’ Local/Regional discussions.
