Nissan Leaf fans design more accurate state-of-charge meter
If you get enough like-minded individuals together, they can accomplish quite a lot. Take, for instance, a group of fans on the MyNissanLeaf forum who wanted a more accurate way to tell how much further they could drive their Nissan Leaf. They accomplished this goal by coding up a device that plugs into the OBD-II diagnostics port and returns the exact state of charge of the battery.
