Charged EVs | Our Subsequent Power exams 750-mile battery pack in a Tesla Mannequin S


A two-year-old Michigan startup, Our Subsequent Power (ONE), has constructed a customized battery pack that lately propelled a modified Tesla Mannequin S for 752 miles. John Voelcker, writing in Automotive and Driver, reviews that ONE retrofitted the automotive with a pack that shops twice the power of Tesla’s authentic, and suits in precisely the identical house.

“We wish to speed up the adoption of EVs by eliminating vary anxiousness, which holds again customers as we speak,” stated ONE founder and CEO Mujeeb Ijaz—a battery engineer whose 30 years of expertise consists of sojourns at Apple, A123 Programs and Ford.

ONE put in its 207.3 kWh pack in a Tesla Mannequin S Lengthy Vary Plus. The automobile’s authentic pack had a capability of 103.9 kWh. ONE’s pack is much extra energy-dense, however its effectivity (measured in miles per kWh) is roughly the identical. That’s an much more spectacular feat when you think about that Tesla’s autos are among the most effective EVs on the highway.

ONE drove the modified Mannequin S for about 14 hours at a median 55 mph, on a cold December day in Michigan, and recorded a spread of 752.2 miles. In a dynamometer check, additionally at 55 mph, the pack delivered an much more spectacular 882 miles.

ONE calls its experiment with the Mannequin S a proof of idea for a future battery know-how known as Gemini, which it hopes to place into manufacturing after 2023. The corporate says its battery chemistries are “safer” and “sustainable,” and use a “conflict-free provide chain.” ONE makes use of a lithium iron-phosphate (LFP) chemistry, which traditionally has decrease power density than cobalt- or nickel-based chemistries.

ONE lately employed Steven Kaye—beforehand of Wildcat Discovery Applied sciences and Apple—as CTO to steer cell analysis efforts, with a deal with bringing to market excessive power chemistries and dealing with cell producers to speed up scale-up of their applied sciences’ path to market.

The corporate’s first battery product, Aries, is scheduled to enter manufacturing late this 12 months. Aries options prismatic LFP cells, and makes use of a structural cell-to-pack structure with no separate modules, which is supposed to mitigate the energy-density drawback of the LFP cells.

For Gemini, the corporate instructed Automotive and Driver that it plans to complement the lower-cost LFP cells with particular “range-extender” cells that can kick in for only one p.c of the automobile’s obligation cycle. These will use a graphite-free anode, which the corporate says “makes extra quantity accessible for the cathode” and will increase power density. The cathode can be product of a proprietary manganese-rich materials.
