Patent applications

Battery X Rebalancing Technologies' first patent application, the battery pack balancing method and system, presents a novel solution to the common problem of unbalanced battery cells in a battery pack—a problem 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, causing some cells to reach full charge or depletion before others. As a result, conventional battery management systems (BMS) interrupt the charging or discharging process based on the weakest cell, wasting the remaining potential of the other cells. This development solves this problem with an intelligent system that continuously monitors and adjusts the state of charge (SOC) of each group of cells (called "strings"). The system consists of a display controller (which controls operational performance), a charger and discharger (which controls the overall energy flow), and an equalizer (which precisely adjusts the individual strings). By intelligently distributing charging and discharging processes among the individual cells, the system ensures that all cells reach their full capacity and discharge evenly, maximizing usable energy, detecting early signs of deterioration, increasing safety, and extending the overall lifespan of the battery pack.

The second patent application, for two-wire charging and remote voltage sensing, introduces a streamlined method for charging a battery and measuring its voltage using only two wires, significantly reducing system complexity and hardware costs. Conventional battery systems typically require separate cables or sensors to monitor the voltage during charging, introducing additional material costs and design challenges, particularly in large-scale applications such as electric vehicles or grid-connected storage. The present invention enables both functions over the same pair of wires by briefly interrupting the charging current, opening a switch, and measuring the battery voltage over the same wires at that moment. A pulse-isolated driver circuit ensures safe and reliable operation, even under fluctuating or unstable voltage levels. The result is a simplified yet highly accurate system that maintains the integrity of the voltage readings while eliminating the need for redundant hardware. This two-wire approach provides a more efficient and cost-effective solution for modern battery systems that require reliability, safety, and scalability.
