Experimental Battery Gives An Impressive 752-Mile Range To A Tesla Model S

Michigan-based One (Our Next Energy) announced that a prototype of its Gemini battery offered 752 miles (1,210 km) of real-world range to a Tesla Model S on a single charge.

The test was conducted on December 17, 2021, with the battery-swapped Tesla Model S traveling from Detroit all the way up to the Mackinac Bridge and back, averaging 55 mph (88.5 km/h). The model was also tested inside the premises, where it achieved 882 miles (1,419 km) of range with the same average speed thanks to the ideal conditions on the dyno – minimum friction, no inclines, and no need for stopping.

The “word’s first range-extended dual-chemistry battery” has a capacity of 203.7 kWh and a high energy density of 416 Wh/L, while it is using artificial intelligence to maximize range. For a good measure, the Tesla Model S Long Range Plus is fitted with a 103.9-kWh battery right from the factory offering a 405-mile (652 km) range.

Mujeeb Ijaz, a battery systems engineer who is the founder and CEO of One, said “We want to accelerate the adoption of electric vehicles by eliminating range anxiety, which holds back most consumers today. We are now focused on evolving this proof-of-concept battery into a new product called Gemini, which will enable long-distance trips on a single charge while improving cost and safety using sustainable materials” adding that their product is “doubling the available energy on board in the same package space”.

One was founded in 2020 and according to the official website it has received support from established companies including the BMW i Ventures, Volta, Flex, Breakthrough Energy, and Assembly Ventures. In late 2022 the company will begin production of its first product called the Aries, followed by a demonstration of a production prototype of the Gemini battery in 2023. The company estimates that the battery will offer a range of 700 miles (1,126 km) to conventional trucks and SUVs.
