Extended Battery Life Claimed by Fast Charge Company

Extreme fast charging specialist StoreDot is claiming a breakthrough in extending automotive battery life.

The Israeli company says its latest technology can extend the lifespan of batteries not only during the vehicle lifespan but also for ‘second life’ applications. Its technology claims to combine the electrochemistry system of the company’s silicon dominant cells to ensure that there is minimal drop off in performance even as the battery ages beyond its useful EV life.

The company says performance is maintained after 1,000 cycles and 80% capacity, the point at which rival lithium-ion fast charging technologies start to rapidly deteriorate in performance. Even after 1,700 cycles, long after the accepted industry norm, StoreDot’s batteries claim to maintain 70% of the original capacity, making them effective in second life use for less dynamic applications such as in energy storage and grid load balancing systems.

This system works in tandem with the company’s self-repairing cells system, which identifies underperforming cells in the electric vehicle and takes them out of service to fix them. Dr Doron Myersdorf, StoreDot CEO, said: “We now have the ability to hugely extend the life of our batteries, long after their vehicle service life. This not only has benefits for the drivers of EVs, allowing them to maintain performance of their vehicles for many more years, but also in second-life applications. Not only will this transformative development encourage more people to drive EVs but this technology has huge benefits for sustainability too, reducing the need to retire and recycle an expensive component that can now serve in critical second life applications.”
