Latest Patents

One of his latest patents is a "System for diagnosing insulating element in BMS." This invention relates to a system that diagnoses an insulation element within a battery management system (BMS). The system utilizes an input terminal and an output terminal of the insulation element to obtain a battery pack diagnosis signal. This signal is output through a battery monitoring circuit and passes through the insulation element. The abnormality of the insulation element is diagnosed based on a bit operation value of the obtained battery pack diagnosis signal. Alternatively, the system can also diagnose the insulation element based on a transceived communication signal.

Another notable patent is the "Switch deterioration detection device and method." This invention provides a device and method for detecting switch deterioration. The device includes a resistor connected in series with a battery, which is controlled through a switch. It features a first differential amplifier that amplifies the voltage difference across the switch and outputs it as a first output voltage. A second differential amplifier amplifies the voltage difference across the resistor, outputting it as a second output voltage. A comparator then compares these output voltages, while a controller determines whether the switch has deteriorated based on the comparison results.
