Add 40 miles driving range to Nissan Leaf with Enginer's add-on battery pack
In the gasoline cars market there is a large industry supplying add-on parts and accessories for a wide range of purposes. In the due course of time there will surely be an accessories market for electric or hybrid cars. Enginer is one such company, being most famous for the plug-in Prius conversion kit that's been on the market for several years. The company recently announced, on the My Nissan Leaf forum, a range of add-on battery packs for the Nissan Leaf to extend the Leaf's driving range by as much as 40 miles.
Getting a long driving range with an electric car is simply a matter of carrying enough energy storage capacity. The huge range of the Tesla Model S (EPA certified at 265 miles) is due simply to the 85 kilowatt-hours of energy storage, compared to the 73 mile driving range of the Nissan Leaf due to its 24 kilowatt-hour battery pack. When you buy an electric car you're stuck with the design considerations of the company which built the car. But what if you could add modifications to the car? Gasoline car owners do this all the time, why not electric car owners?
What Enginer has done is develop a method of tapping into the Leaf's high voltage power system, to add additional battery capacity. Kit installation does not cut any wires, and the car can be returned to stock state at any time. The company claims it does not void the Leaf's warranty.
