Battery X Metals Inc. has filed two U.S. provisional patent applications covering proprietary software and hardware technologies for diagnosing, rebalancing, and extending the lifespan of lithium-ion and EV batteries. The patents were filed through the company’s wholly-owned subsidiary, Battery X Rebalancing Technologies Inc., reinforcing its mission to deliver advanced, sustainable solutions across the battery technology value chain.
The patent filings coincide with the company’s development of its Prototype 2.0 next-generation battery diagnostic and rebalancing system. The unit’s commercial release is targeted for April 2025 and will feature optimized hardware dimensions, enhanced state-of-health diagnostics, airtightness testing, and improved connectivity.
National Research Council of Canada System Validation
Beyond its recent patent filings, Battery X Rebalancing Technologies has also announced that the National Research Council of Canada (NRC) has validated its core rebalancing and diagnostics system. Tests conducted on 12-cell (100Ah) and 15-cell (72Ah) lithium-ion battery modules confirmed the system’s capability to recover nearly all lost capacity due to cell imbalance. The NRC validation also confirmed system accuracy, performance consistency, and safety, affirming the platform’s potential for broader commercial applications.
Battery X Rebalancing Technologies complements the Company’s two other core verticals:
- The exploration of North American critical battery metal projects.
- The development of proprietary, eco-friendly technologies to recover battery-grade materials from end-of-life lithium-ion batteries.
A Growing Need for Battery Lifespan Extension Solutions
Global EV sales exceeded 17 million in 2024, and nearly 40 million vehicles are projected to be out of warranty by 2031. This trend underscores the increasing demand for battery lifespan extension technologies that can reduce replacement costs, address performance degradation, and support a more sustainable EV ownership model. Battery X Rebalancing Technologies targets cell-level degradation by diagnosing and correcting internal pack imbalances that reduce battery capacity over time.
U.S. Patent Application Summaries
The first application, Method and System for Battery Pack Adjustment, introduces a system that intelligently monitors and balances the state of charge (SOC) across cell groups, or “strings.” The system architecture includes a display controller, integrated charger/discharger, and equalizer that work together to enable synchronized charge and discharge operations. This approach increases usable energy, detects early signs of degradation, and extends battery life.
The second application, Two-Wire Charging and Remote Voltage Detection, outlines a system capable of both charging and voltage monitoring through the same wire pair. This novel design significantly reduces system complexity and wiring costs by eliminating the need for separate voltage sensing circuits. A pulse isolation drive circuit ensures accurate measurements and system safety during brief charge interruptions.
Prototype 2.0 Development and Testing
Following the successful testing of its first-generation unit, Battery X Rebalancing Technologies is finalizing Prototype 2.0 with updates in size, performance, diagnostics, and interoperability. Upon completion, the new unit will undergo rigorous testing to validate its application suitability across multiple EV battery architectures. The company aims for the system to help reduce battery-related ownership costs, support a circular economy, and extend the useful service life of lithium-ion batteries.
Strengthened Market Alignment with Subsidiary Rebrand
On April 7, 2025, Battery X Metals also rebranded its battery technology subsidiary from Li-ion Renewable Technologies Inc. to Battery X Rebalancing Technologies Inc., aligning with its corporate brand strategy. The move followed the company’s acquisition of all remaining subsidiary shares, bringing it under full ownership.
“This rebranding ensures our subsidiaries are clearly aligned under the Battery X identity,” said Massimo Bellini Bressi, Chief Executive Officer of Battery X Metals. “It reinforces our commitment to innovation and supports our long-term vision of delivering scalable, sustainable solutions across the full battery value chain.”
