Latest Patents
Do Hyun Yoon holds a patent for a charge controller designed to respond to extreme transients in current, voltage, and temperature. This charge controller effectively monitors the drift of the battery charging rate versus its request. It compensates for wind-up that may lead to uncontrolled current into a high-voltage battery. The bi-directional anti-wind-up charge controller allows the battery management system to independently adjust the current request to the charger. This feature is particularly useful during vehicle component failures, charger side faults, and uncontrolled current situations. The design ensures safe and continuous charging during unexpected charger events. Additionally, a dynamic saturation bound enables the charge controller to adjust its requested current and compensate for auxiliary current draws when the charger can provide more current. The charge controller intelligently switches between voltage and current control based on the battery's voltage, adapting to variability in state-of-health and temperature of the battery pack.
