Did One Next Energy (ONE) achieve unprecedented performance on a Tesla Model S? This is what reports in any case Electrek, relayed by PhonAndroid, since the company specializing in battery technology claims to have doubled the range of the car. Thanks to a new kind of battery, it would have made the Tesla travel the equivalent of 1,210 kilometers (752 miles) on a single charge. Until now, a Tesla Model S has never exceeded 650 kilometers.

By driving at a little less than 90 km / h, the car would have succeeded in this famous bet. In a press release, the company highlighted its know-how which “allowed an electric vehicle to travel 1,200 kilometers without being recharged”. To testify to the truth of the facts, ONE has uploaded a two-minute video where a driver is in a Tesla Model S. We follow his journey through Michigan with a loop around Detroit. Coming back to the city, there is still 10% but the 1,100 kilometers have already been exceeded.

A battery that keeps its mysteries

If at first, the American firm did not wish to reveal what this battery was made of in order to obtain such performance, it finally responded to Electrek : “The battery system has an energy density of approximately 416 Wh / L and uses a nickel-cobalt-manganese cathode and a graphite anode.” Very technical details, to which were added some clarifications: “The pack added 331 kg in total to the initial mass of the battery while adding 99.8 kWh of energy. The density of the tested pack was 231 Wh / kg “.

For the moment, this battery is still in the testing stage and commercialization is not yet planned, not to mention the price that a technology would imply. One Next Energy also says it is working on other projects and prototypes for the coming year. In November, Capital tested a trip in a Tesla Model 3 Grande Autonomie between Paris and Bordeaux. It had taken several stops and recharges to reach the final destination.
