Range Rover Electric gets Fortescue’s range-boosting battery tech

JLR will use new battery management software in its upcoming electric cars that is claimed by its maker to boost their range, performance and lifespan – without the need for any additional hardware. 

The software developed by Elysia, the battery technology spin-off of Fortescue-owned WAE (previously Williams Advanced Engineering), is used to monitor the health of a particular car’s battery pack, and will first be deployed on the Range Rover Electric coming next year. 

Elysia’s software uses artificial intelligence and six proprietary algorithms that are claimed to provide a more accurate picture of the cells’ states of charge, which is said to translate into a better picture of a battery’s overall health.

Tim Engstrom, WAE’s technical lead for advanced batteries, last year told Autocar: “Nearly always, conventional methods overestimate the health of a battery.

“The containment solution that’s in place today is to put these big energy reserves or buffers that you’re not allowed to use to account for this uncertainty – and there’s actually quite a large uncertainty. That’s to stop the customer being stuck on the side of the road.

“And if anything, this problem is getting worse as the industry is kind of under pressure to shrink these buffers and to use more and more of the battery to unlock range for their customer and be more competitive.”

By providing a clearer picture of a battery’s health, Elysia’s algorithms could allow manufacturers to shrink these buffers, suggested Engstrom.

They are claimed to yield up to 10% more range, increase battery life by 30% and significantly reduce charging times.

Elysia’s algorithms are also capable of actively adapting a battery’s performance based on its health, providing a more gradual decline in performance over time compared with current technologies.
