Battery X Metals Inc. has taken a major step toward revolutionizing electric vehicle (EV) battery maintenance with the successful real-world validation of its proprietary battery rebalancing technology, developed through its subsidiary Battery X Rebalancing Technologies Inc. The milestone builds on provisional patent filings announced in April and marks a breakthrough in extending the lifespan and efficiency of lithium-ion batteries used in EVs.
The company’s Prototype 2.0 rebalancing machine was tested on both passenger and commercial vehicle battery packs. A recent trial on a 96-cell Nissan Leaf battery pack—representing a common out-of-warranty EV—demonstrated the unit’s precision, recovering 100% of imbalance-related capacity and restoring 1.95 ampere-hours, a 3.9% increase in usable capacity.
A second, more demanding trial involved a 144-cell commercial Class 3 electric truck battery pack. Despite significant imbalance and degradation, the system recovered 66.3 ampere-hours, equating to a 37.7% recovery of the battery’s Rated Capacity and again, a 100% recovery of imbalance-related losses.
“These trials confirm what we filed with the USPTO,” said Massimo Bellini Bressi, CEO of Battery X Metals. “Our technology works—and it works in the real world, where imbalance-related degradation directly affects EV performance, range, and lifespan.”
Unlocking a Multi-Billion Dollar Market
As EV adoption surges, so too does the challenge of maintaining battery performance beyond manufacturer warranties. By 2031, an estimated 40 million EVs will fall outside of warranty, creating a critical need for cost-effective reconditioning solutions.
Battery X’s rebalancing technology addresses this head-on by restoring performance to lithium-ion batteries suffering from common voltage imbalances. Traditional battery management systems (BMS) cut off power based on the weakest cell, wasting the full potential of the battery. Battery X’s system ensures that all cells charge and discharge evenly, improving safety, increasing energy output, and extending battery life.
Backed by National Research Council of Canada
In addition to real-world EV testing, the company’s technology was validated by the National Research Council of Canada (NRC). A test involving 15-cell LiFePO₄ modules showed dramatic results: after inducing imbalance, Battery X’s technology restored nearly all lost capacity, increasing output from 46.24Ah to near-original levels.
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
These innovations prepare the platform for commercial scale-up across fleets and private EV owners, offering solutions that could save billions in replacement costs while supporting sustainability goals.
Two Patent Applications, One Vision
Battery X has filed two provisional patents with the USPTO:
- Battery Pack Adjustment System – a smart, equalization-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.
Together, these innovations aim to redefine battery health management with real-time balancing, reduced hardware needs, and scalable design for modern EV and grid storage systems.
With its validation phase ongoing, Battery X Rebalancing Technologies plans to test across more battery platforms and chemistries, supporting a future transition from provisional to full utility patents and positioning the firm as a first mover in the growing EV battery rebalancing and lifespan extension market.
As EV demand intensifies globally, Battery X is poised to meet one of the sector’s biggest challenges: keeping aging batteries running stronger, longer, and more sustainably.
