reflect performance observed under controlled service conditions and may vary across vehicles, battery
conditions, and operating environments.
Additional performance gains were observed on the BYD Seal and BYD Han platforms. On the BYD Seal,
estimated driving range increased from approximately 597 kilometers to approximately 631 kilometers
per charge, representing an estimated increase of approximately 34 kilometers. On the BYD Han,
estimated driving range increased from approximately 275 kilometers to approximately 296 kilometers
per charge, representing an estimated increase of approximately 21 kilometers.
While the magnitude of improvement varied across platforms, the increase in effective driving range
across all evaluated vehicles demonstrates the potential for future commercial relevance. These results
were observed under specific test conditions, and actual performance may vary depending on battery
health, usage history, environmental factors, and other operational variables.
The observed increases in estimated driving range represent material improvements in vehicle usability.
For individual drivers, this may translate into reduced charging frequency and greater route flexibility. For
fleet operators, incremental range gains may directly enhance operational efficiency and reduce
downtime. In practical terms, the recovery of up to approximately 84 kilometers of effective driving range
may meaningfully alter the economics and usability profile of electric vehicles without requiring costly
battery replacement, particularly in cases where underlying battery chemistry remains viable.
Commercial Significance and Relevance of BYD to the Global EV Ecosystem
BYD is the largest electric vehicle manufacturer globally by unit sales, with annual new energy vehicle
deliveries exceeding 4.5 million units.1 BYD’s product portfolio spans passenger electric vehicles, plug-in
hybrid vehicles, and commercial electric transportation platforms, positioning BYD as a central participant
in the global transition to electrified mobility.
The BYD Song platform, in particular, represents one of the largest single electric vehicle populations
globally within the compact SUV category. Demonstrating a measurable and significant increase in
estimated driving range on this platform underscores the scalability and commercial relevance of the
Company’s next-generation solution within one of the largest EV ecosystems in the world.
As these vehicles continue to age, a growing proportion is expected to transition beyond original battery
warranty coverage over the coming years. This transition is expected to increase exposure to battery
performance degradation, reduced effective driving range, and costly replacement requirements.
Technologies capable of restoring usable battery capacity without module replacement may represent a
cost-effective and environmentally responsible pathway to extend battery lifespan and reduce total cost
of ownership.
Positioning Within a Growing Battery Lifecycle Opportunity
The Company is developing its patent-pending rebalancing platform to address a structural lifecycle
challenge within the global electric vehicle market. The ability to demonstrate measurable range recovery
across multiple high-volume platforms manufactured by the world’s leading EV producer illustrates the
potential economic and operational impact of targeted battery optimization.
Additional validation and expanded testing across broader vehicle populations, battery chemistries, and
operating conditions remain ongoing as the Company advances toward scalable deployment and
commercialization.
The Problem: Rising EV Adoption Presents New Battery Lifecycle Challenges
In 2024, global EV sales reached approximately 17.1 million units, representing a 25% increase from 2023.2
With cumulative global EV sales from 2015 to 2023 totaling an estimated over 40 million units, 3 a
significant share of the global EV fleet is expected to exit warranty coverage over the coming years. 4,5
By 2031, nearly 40 million electric, plug -in hybrid, and hybrid vehicles worldwide are anticipated to fall
outside of their original warranty coverage.4.5 This projection is based on current EV adoption figures and
standard industry warranty terms, and underscores a growing risk for EV owners facing battery
degradation, reduced capacity, and costly replacement requirements.6 As the global EV fleet continues to
expand, the demand for technologies that extend battery life, reduce long -term ownership costs, an d
support a sustainable transition to electric mobility is increasing.
The Solution: Pioneering Next-Generation Technologies to Support Lithium-Ion Battery Longevity
Battery X Rebalancing Technologies’ proprietary software and hardware technology aims to address this
challenge by extending the lifespan of EV batteries. This innovation is being developed with the aim to
enhance the sustainability of electric transportation and the goal to provide EV owners with a more cost-
effective, environmentally friendly ownership experience by reducing the need for costly battery
replacements.
Battery X Rebalancing Technologies’ rebalancing technology, validated by the National Research Council
of Canada (“NRC”), focuses on battery cell rebalancing. The NRC validation demonstrated the technology’s
ability to effectively correct cell imbalances in lithium-ion battery packs, recovering nearly all lost capacity
due to cell imbalance. The validation was conducted on battery modules composed of fifteen 72Ah
LiFePO₄ cells connected in series. The cells were initially balanced to a uniform state of charge (SOC), with
a measured discharge capacity of 71.10Ah. In the validation test, three of the fifteen cells were then
artificially imbalanced—one cell was charged to a 20% higher SOC, and two cells were discharged to a 20%
lower SOC—resulting in a reduced discharge capacity of 46.24Ah, representing a decrease of
approximately 35%. Following rebalancing using Battery X Rebalancing Technologies’ rebalancing
technology, the battery module’s discharge capacity was restored to 70.94Ah, representing the recovery
of approximately 99% of the capacity lost due to cell imbalance.
These advancements establish Battery X Rebalancing Technologies as a participant in lithium -ion and EV
battery solutions, aiming to tackle the critical challenges of capacity degradation of battery packs and
expensive replacements. By extending the lifecycle of battery materials within the supply chain, Battery X
Rebalancing Technologies aims to support the energy transition and promote a more sustainable future.
