Title: Kyu-Ha Park: Innovator in Battery Management Systems
Introduction
Kyu-Ha Park is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of battery management systems, holding a total of 5 patents. His work focuses on improving the efficiency and effectiveness of battery charging and state estimation.
Latest Patents
One of his latest patents is a battery management system that includes an apparatus for estimating battery state. This invention features a measurement unit that measures terminal voltage, charging/discharging current, and a current offset value of a battery. It also includes a prediction unit that predicts state and output variables based on a state equation involving state variables such as state of charge (SOC) and overpotential. Additionally, a correction unit is incorporated to refine the predicted state variable, while a SOC estimation unit estimates the SOC using the corrected state variable. The control unit selects a state variable for SOC estimation based on the measured current offset value.
Another notable patent is an apparatus and method for charging a battery by lowering charge power in phases. This invention includes a voltage measuring unit and a control unit that outputs charge control signals for both early and late charging modes. The late charging mode involves reducing charge power in phases, which is linked to the voltage of the battery reaching a preset cut-off voltage. This innovative approach allows for a more efficient full charge of the battery.
