Our Next Energy, also known as ONE, installed one of its battery packs in a Tesla Model S and managed to have it travel 752 miles on a single charge.

The Model S is Teslas longest-range vehicle with up to 405 miles of range on a single charge depending on the configuration.

CEO Elon Musk has often said that Tesla could make it have an even longer range by jamming a 120 kWh battery pack in it, but the automaker instead focuses on achieving a longer range through better efficiency.

In order to showcase its own battery technology, Our Next Energy (ONE) has now installed its own battery system in a Model S.

The company did a test drive with an average speed of 55 mph and achieved a range of 752 miles:

Our Next Energy, Inc. (ONE), a Michigan battery technology company, has demonstrated a proof-of-concept battery that powered an electric vehicle 752 miles without recharging. The vehicle completed a road test across Michigan in late December with an average speed of 55 mph. The results were validated by a third party using a vehicle dynamometer where the test vehicle, a Tesla Model S retrofitted with an experimental battery, achieved 882 miles at 55 mph.

That is so impressive. I love seeing innovation like this. EV batteries get reduced range in cold weather, so to go 752 miles across Michigan in late December is really awesome. I'm assuming that 3rd party company's test that got 882 miles was done at a more reasonable temperature.

The experimental battery is about 729 pounds heavier, but it's much more energy dense. Hopefully all the testing on that kind of battery works out so they can start putting them in production EVs.

Put'em on phone as well

Cool

Im sure my next car will be an EV, but Im still using an old Honda

I don't why the government allows this to be the speed that "highway" mileage is determined. It greatly inflates the mpg since there aren't very many highways that still use 55 mph as their speed limit.

I'd hope so. I read yesterday that Mercedes just tested one that got close to that.
