Israel-based StoreDot, the pioneer and leader of extreme fast charging (XFC) batteries for electric vehicles, has filed a patent for a technology innovation that promises to rapidly increase the crucial ‘miles per minute’ of charging ratio, thus significantly bringing down EV charging times, claims the company.
The rate of miles per minute of charging remains a major barrier to EV ownership for many potential buyers.
The company has also made the technology available through open source to benefit the automotive and battery ecosystem. StoreDot is making the technology available to other organisations to help expand current charging infrastructure, speed up the global adoption of EVs and create a zero-emissions world in the future.
The patent pending technology incorporates hardware and software advances that create a 'booster' feature, allowing the battery to analyse the capability of the charging station in real time and to adjust the battery's ability to carry high current rates, said the company.
This communication between a vehicle's XFC battery and charging system allows the cells to be charged faster, safely accepting a higher current without overheating. It also has the ability to immediately boost existing infrastructure systems, enabling faster charging, and thus optimising future fast-charge technologies without the need to upgrade to newer equipment in the near future.
Dr Doron Myersdorf, CEO, StoreDot called this an important step for the EV global community as “it will allow all of us to charge faster with very minimal changes to the current infrastructure and future deployment process. That is why we believe it's critical to offer this world-leading innovation to other organisations on an open-source basis.”
“The global uptake and appeal of electric vehicles is crucial if we want to live in a cleaner, zero-emissions world and by sharing this novel approach StoreDot aims to play a pivotal role in helping to achieve this objective. We want to work with and support the global community, including automotive manufacturers and infrastructure providers in their missions as well, especially when the industry is facing a number of charging infrastructure deployment challenges, not least the global semiconductor shortage,” Dr Myersdorf said.
StoreDot has been making rapid advancement in extreme fast charging lithium-ion batteries for use in the automotive sector. The XFC batteries will deliver a 50% reduction in charging time at the same cost, claims the company, which is in advanced talks with many global carmakers. It is on track to deliver these mass-produced XFC batteries by 2024.
The company is also working on a next generation extreme energy density (XED) solid state technology that will enter mass production in 2028.
