With the successful real-world validation of its unique battery rebalancing technology, created through its subsidiary Battery X Rebalancing Technologies Inc., Battery X Metals Inc. has made significant progress in revolutionising electric vehicle (EV) battery management. The milestone represents a breakthrough in increasing the longevity and efficiency of lithium-ion batteries used in electric vehicles (EVs) and builds on provisional patent filings made in April.
Battery packs from both passenger and commercial vehicles were used to test the company’s Prototype 2.0 rebalancing device. A 96-cell Nissan Leaf battery pack, which represents a typical out-of-warranty EV, was used in a recent test to show off the accuracy of the device. It recovered 100% of the imbalance-related capacity and restored 1.95 ampere-hours, which is a 3.9% increase in usable capacity.
A commercial Class 3 electric truck battery pack with 144 cells was used in a second, more rigorous test. The system recovered 66.3 ampere-hours, which translates to a 37.7% recovery of the battery’s rated capacity and, once more, a 100% recovery of imbalance-related losses, despite considerable imbalance and deterioration.
“What we filed with the USPTO is confirmed by these trials,” stated Massimo Bellini Bressi, CEO of Battery X Metals. “Our technology works—and it works in the real world, where EV performance, range, and lifespan are directly impacted by imbalance-related degradation.”
Opening a Market Worth Billions of Dollars
The difficulty of preserving battery performance after product warranties increases along with the popularity of EVs. An estimated 40 million EVs are predicted to be out of warranty by 2031, necessitating the development of affordable reconditioning alternatives.
The rebalancing solution from Battery X tackles this directly by giving lithium-ion batteries that experience frequent voltage imbalances their performance back. Conventional battery management systems (BMS) waste the battery’s full capability by cutting off power depending on the weakest cell. By ensuring that every cell charges and discharges uniformly, Battery X’s method enhances safety, boosts energy production, and prolongs battery life.
Supported by Canada’s National Research Council
The National Research Council of Canada (NRC) validated the company’s technology in addition to conducting real-world EV testing. The results of a test using 15-cell LiFePO₄ modules were striking: Battery X’s technology restored almost all of the lost capacity after creating imbalance, bringing output back to levels close to the initial 46.24Ah.
Compact Design, Commercial Readiness
Prototype 2.0 represents a leap forward in both functionality and field deployment readiness. It features:
- Compact design for mobile use
- Multi-function diagnostics for State-of-Health (SOH) assessments
- Insulated tool kits and battery lifts for operator safety
- Enhanced connectivity for data integration and future upgrades
By providing solutions that might reduce replacement costs by billions of dollars and advance sustainability objectives, these innovations set the stage for commercial scale-up across fleets and private EV owners.
Two Patent Applications, One Vision
Battery X has filed two provisional patents with the USPTO:
- Battery Pack Adjustment System – a smart, equalisation-based system for uniform SOC (state of charge) across cell groups.
- Two-Wire Charging & Remote Voltage Detection – a novel method that reduces system complexity by using the same wire pair for charging and voltage monitoring.
With real-time balancing, fewer hardware requirements, and scalable design for contemporary EV and grid storage systems, these advances collectively seek to revolutionise battery health management.
In order to support a future transition from provisional to full utility patents and establish the company as a pioneer in the expanding EV battery rebalancing and lifespan extension market, Battery X Rebalancing Technologies intends to test across additional battery platforms and chemistries while its validation phase is still ongoing.
Battery X is well-positioned to address one of the industry’s most pressing issues as EV demand rises globally: maintaining older batteries’ strength, longevity, and sustainability.
