Abstract: The present disclosure relates to a wireless battery management system which ensures stability when obtaining battery data through wireless communication. The battery management system includes a manager node operating a primary channel and a secondary channel based on wireless communication and obtaining battery data from a monitor node by using the primary channel or the secondary channel and a monitor node connected to a battery module to collect battery data including one or more of a current, a voltage, a temperature, and self-diagnosis data of the battery module, transmit the collected battery data to the manager node through the primary channel, and when the transmission of the battery data through the primary channel fails, transmit the battery data to the manager node through the secondary channel.

Abstract: The present disclosure relates to an LED driving technique. The present disclosure provides a technique of measuring a time for reaching a forward voltage of a currently driven LED by comparing a forward voltage sensed in a previous scan line and an LED voltage sensed in a current scan line and for compensating for an ON period of a PWM (pulse width modulation) signal by the measured time for reaching the forward voltage.
