    • 752 mile range out of Tesla Model S with experimental battery

      Over 700 miles on one charge? That would definitely change the EV landscape as well as reception to EV's regarding long distance travel. Well, a Tesla Model S equipped with a battery from Michigan startup Our Next Energy did just that.


      The battery from Our Next Energy or ONE fits in the same space but holds twice the energy.

      The original Tesla battery had a capacity of 103.9 kilowatt-hours, while the prototype ONE battery that replaced it in the same space has 207.3 kWh. CEO Ijaz confirmed to C/D that ONE used "a single pack retrofitted in the same space as the original battery." So it's far more energy-dense, but delivered consumption (in miles per kWh) roughly equal to that of the original battery.

      ONE's drive took place in mid-December in Michigan—with chilly winter temperatures working against range maximization—where the company drove up and down the length of the mitten state for nearly 14 hours, averaging 55 mph, before winding up back at its Novi headquarters in southeastern Michigan with the trip odometer showing 752.2 miles. Later, in a much less taxing test, the company put the Model S on a dynamometer at a steady 55 mph, where it ran for a staggering 882 miles on a charge.
      So what next? ONE wants to bring this battery to market in 2023. They are calling it Gemini. Hopefully they pull it off but clearly EV range capability is going to improve considerably in the next few years.

        Promising if true...

        Unfortunately Bill Gates is hugely involved in this company and it is only 2 years old.

        Another possibility is that if they can pack 700 miles into the same size/weight, can they make 350 miles with 1/2 the weight?

        That is where the excitement would truly be.

        What's the real solution, drastically faster charging times, or more capacity? If I could get 300+ miles of range but charge is 10 minutes, then I'm 100% on board. I don't know which is the easier problem to solve.

        Less weight and pretty good range sounds like the answer.

        Let’s hope it is not over promising and under delivering like most of the startups.

        I'm OK with my current charge time of 30-50 min for my Taycan. I do not really need any faster DC charging right now. I mostly charge 240V at 50AMPs anyways and a full charge takes place is less than 4 hours for "free" in my condo (part of HOA fees, so not really "free" I guess).

        My situation is different than it may be for others as I drive 100 miles (mostly less) a week.
