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 2023⁴. With cumulative global EV sales from 2015 to 2023 totaling an estimated over 40 million units⁵, a significant share of the global EV fleet is expected to exit warranty coverage over the coming years.

By 2031, nearly 40 million electric, plug-in hybrid, and hybrid vehicles worldwide are anticipated to fall outside of their original warranty coverage^6,7. 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 requirements⁸.

Patent Applications

Battery X Rebalancing Technologies' first patent application, method and system for battery pack adjustment, introduces a novel solution to address the common issue of imbalanced battery cells within a battery pack - an issue that leads to reduced capacity, safety concerns, and shortened lifespan. In most battery packs, cells charge and discharge at different rates due to variations in manufacturing, internal resistance, and temperature, which causes some cells to reach full charge or depletion before others. As a result, traditional battery management systems (BMS) cut off charging or discharging based on the weakest cell, wasting the remaining potential of other cells. This invention solves that problem through a smart system that continuously monitors and adjusts the state of charge (SOC) of each group of cells (referred to as "strings"). The system includes a display controller (which manages operations), a charger and discharger (handling overall energy flow), and an equalizer (which precisely adjusts each string). By allocating charge and discharge intelligently across the cells, the system ensures they all reach full capacity and deplete evenly, thereby maximizing usable energy, detecting early signs of degradation, enhancing safety, and extending the overall life of the battery pack.

The second patent application, for two-wire charging and remote voltage detection, presents a streamlined method to charge a battery and measure its voltage using only two wires-significantly reducing system complexity and hardware costs. In conventional battery systems, separate wires or sensors are typically required to monitor voltage during charging, which adds material costs and design challenges, especially in large-scale applications like electric vehicles or grid storage. This invention enables both functions over the same wire pair by briefly pausing the charge current, opening a switch, and using that moment to measure the battery's voltage through the same lines. A pulse isolation drive circuit is used to manage this operation safely and reliably, even when voltage levels are floating or unstable. The result is a simplified yet highly accurate system that maintains the integrity of voltage readings while eliminating the need for redundant hardware. This two-wire approach offers a more efficient and cost-effective solution for modern battery systems that demand reliability, safety, and scalability.
