StoreDot says it has secured a patent for a digital battery system for EVs.
The new system developed by StoreDot will be open-source and available to any other technology provider.
The Israeli company notes it is “furthering its mission to enhance the entire electric vehicle ecosystem,” with an approved patent for a technology giving automotive batteries fixed capacity and driving range during their lifespan.
The digital battery breakthrough, achieved through a combination of patented software and cell chemistry management, gives an EV owner a fixed battery driving range for the duration of its useful service life.
It manages both charging voltages and StoreDot’s XFC silicon-based cell chemistry to stress a battery less at the start of its life and balance its performance across the battery’s life to deliver a driving experience with predictable and consistent range.
As with previous patented technologies, StoreDot is making the technology available to other organisations.
“Our development of extreme fast charging batteries is aligned with our commitment to the holistic improvement of the EV battery ecosystem,” said StoreDot CEO, Doron Myersdorf.
“We want to make it more attractive for consumers to adopt zero-emissions electric vehicles. This new patent, which we will make available to any organisation as open-source, is another example of that commitment.
“Our new digital battery software, aligned with our silicon-based cell chemistry, will give all EV owners guaranteed battery performance and range throughout the ownership of their vehicles. Battery degradation is one of the main bugbears of long-term EV ownership and it’s essential we all do everything we can to promote the mass adoption of EVs, on our critical path to live in a cleaner world.”
StoreDot’s new digital battery patent comes shortly after its announcement of an application for charging booster technology, which will reduce vehicle charging times in limited charging stations. The system analyses the charging station power in real-time, allowing the XFC battery to accept higher charging rates without overheating.
The company is also making this technology available to other organisations as open-source.
StoreDot added it is now making advancements in extreme fast charging lithium-ion batteries for use in the automotive sector, increasing the number of miles per minute of charge. It is currently shipping samples to global car makers for real-world testing and remains on track to deliver mass-produced XFC batteries, which, it maintains, deliver a 50% reduction in charging times at the same cost, by 2024.
The company is presenting a roadmap also for its next generation XED, extreme energy density solid state technologies, which will enter mass production in 2028.
