Title: **Jong-Woon Yang: Pioneering Innovations in Battery Technology**

Introduction

Jong-Woon Yang, based in Yongin-si, South Korea, is an esteemed inventor known for his significant contributions to battery technology. With 23 patents to his name, Yang has demonstrated a profound knowledge of electrical engineering and energy storage systems, playing a pivotal role in advancements that enhance the efficiency and longevity of batteries.

Latest Patents

Among his most recent inventions is a pioneering **secondary battery charging method**. This innovative approach allows for improved stability and extends the life span of secondary batteries by addressing voltage imbalances among cells. When a voltage discrepancy within the range of 100 mV to 300 mV is detected, the charging method dynamically transitions from a constant current-constant voltage charging method to a pulse-charging method. Furthermore, if the voltage imbalance reaches 300 mV or more, the charging process is halted to safeguard the battery. Conversely, when the voltage imbalance is 100 mV or less, the constant current-constant voltage method continues to be employed, with the charging process automatically ceasing once the battery attains full charge.

Another notable patent is for an **apparatus for controlling battery packs** and an energy storage system that incorporates this apparatus. This innovation features a battery pack consisting of multiple battery trays, each containing several battery cells. The apparatus includes an open circuit voltage (OCV) calculator, which gathers OCV measurements of the battery cells when the battery pack is activated to determine a final OCV. Additionally, it incorporates a state of charge (SOC) estimator that extracts the SOC value based on the final OCV, enhancing the accuracy of energy management in battery systems.
