Don’t compromise EV battery health in extreme fast charging tech race: StoreDot cautions industry

Israel-based StoreDot, the pioneer of extreme fast charging (XFC) battery technology for electric vehicles, has issued a warning to battery developers and electric vehicle manufacturers and cited the importance of transparent communication on XFC including long-term battery health concerns.

The company's announcement is in response to recent industry claims touting fast charge times and extended ranges, which often overlook the potential long-term impact on battery health and the resulting degradation in vehicle’s driving range.

Without proper battery chemistry, frequent fast charges can lead to reduced overall battery lifespan, due to degradation as a result of power charging which can compromise the integrity of battery cells.

Addressing this concern, StoreDot is emphasising the importance of transparent communication from battery developers around critical factors associated with XFC such as battery health, cycle life, performance under extreme temperatures, safety parameters, and costs.

Even after 1300 consecutive XFC cycles on a large 30Ah format cell, StoreDot’s batteries maintain 80% of their original capacity, making them highly durable whilst providing Extreme Fast Charging to EVs.

Dr Doron Myersdorf, StoreDot CEO, says: “At StoreDot we put battery safety at the top of our agenda, ensuring that cells can accept high charge rates without compromising their lifespan. This has been our North Star over the last decade of development as we have continuously refined and improved our technology, and its importance mustn’t be underestimated.

“Even though battery deterioration and a decline in the state of health over the lifetime of the battery are inevitable, EV owners shouldn’t have to sacrifice lifespan and vehicle’s driving range for convenient daily use. A driver should be able to confidently charge at a consistently high rate, every time and regardless of how full the battery is when they arrive at the charging station.

“Additionally, OEMs are increasingly looking to extend battery warranties based on guaranteed states of health within specified mileage ranges. Thus, it's vital that manufacturers future-proof their batteries, whilst considering the increased rollout of higher-powered charging infrastructure and evolving XFC usage patterns.”

INDIA’S OLA AMONG STOREDOT’S INVESTORS

StoreDot's commitment to innovation and collaboration is being demonstrated through its rapidly growing global network of strategic partnerships with investors, leading OEMs, and manufacturing partners. Global automotive and EV manufacturers Volvo, Polestar, VinFast, and Ola Electric are key strategic partners of the company.

Recently, StoreDot reported outstanding battery performance feedback for the A-Samples testing phase of its XFC electric vehicle battery cells. The comprehensive testing programs took place earlier this year over six months by leading global automotive manufacturers from Europe, Asia, and the US, as well as several of StoreDot’s strategic ecosystem partners.

Last year, StoreDot revealed its ‘100inX’ strategic technology roadmap which featured 100in5, 100in3 and 100in2 of miles per minute of charging - three generations of StoreDot technologies of silicon-dominant XFC, semi solid state and post-lithium architectures. The roadmap reaffirms that the timings for these will be delivered to automotive OEMs over the coming decade with 100in5 by 2024, 100in3 by 2028 and 100in2 by 2032.
