Keeping in mind the optimal driver experience through extremely fast charging, StoreDot’s technology has achieved sufficient charge and discharge cycles, to allow car manufacturers to plan for a smaller battery. Smaller packs with XFC (extreme fast charging) translate into improved EV specifications, including better car efficiency, increased use of regenerative braking, reduced carbon footprint and lower costs. As a result, these affordable and lighter electric vehicles will serve a wider audience and further drive the adoption and transition to electric vehicles.

StoreDot is on track to deliver its 100en5 silicon-dominant extremely fast charging batteries to electric vehicle OEMs by next year. This transformative technology will offer 100 miles or 160 km of range in just five minutes of charging. As a result, EV drivers will no longer have to worry about range between charges or charging times, allowing automakers to re-evaluate electric vehicle specifications. With StoreDot’s XFC technology, OEMs will be able to optimize the weight and cost of a vehicle, rather than pushing for ever greater range and battery size.

Going from a mid-range, high-end vehicle requiring an 80 kWh battery to a 50 kWh battery could lead to a weight cut of about 200 kg on the electric vehicle (the equivalent weight of 3 to 4 people) and, more importantly, could reduce the manufacturing cost of the car by as much as $4,500, depending on fluctuations in the cost of metal and improvements in energy density. The environmental impact of such a design change will also be very significant as it will lower the amount of raw materials used in each vehicle, thus reducing its EV carbon footprint throughout its life cycle. XFC in smaller packs also means efficient regenerative braking as it can accommodate the corresponding high recovered currents.
