Abstract: A management system and a control method are disclosed to transmit/share fault state information immediately without constructing a separate communication path for transmitting fault state information.

Abstract: A battery system includes first to N-th battery modules sequentially connected in a daisy chain configuration; and a master controller connected to the first battery module through an interface IC, selecting at least one target module among the first to N-th battery modules, and transmitting a control command for the target module. The target module unidirectionally transmits the control command received from the master controller, and bidirectionally transmits response data generated in response to the control command. The master controller selects the N-th battery module as the target module first, and selects the first battery module as the target module last.

Abstract: A transmission/reception method and device for isolated communication is proposed. The transmission/reception method includes performing transmission, wherein bit streams are extracted from data and two or more predetermined number of bits are modulated into one DC balanced symbol so as to generate a signal in which a plurality of symbols are listed, thereby transmitting the signal through an isolated communication circuit, and performing reception, wherein the signal is received through the isolated communication circuit and the plurality of symbols included in the signal are demodulated into the two or more predetermined number of bits so as to generate the bit streams and organize the bit streams into the data. The transmission/reception method and device may reduce power consumption at the same communication speed because a plurality of bits is represented by the one DC balanced symbol.

Abstract: A battery management system includes a microcontroller unit which transmits and receives communications information through a communications input/output terminal, a fault generator unit which generates fault information and transmits the fault information through a fault information output terminal, and a battery cell monitoring unit which is coupled to the communications input/output terminal and the fault information output terminal and diagnoses an operation of internal function based on the fault information transmitted from the fault generator unit and outputs an internal diagnosis result value to the microcontroller unit.

Abstract: The present disclosure relates to a battery cell monitoring unit having a fault injection terminal and a battery management system using the same. The battery management system includes: a microcontroller unit transmitting and receiving communications information through a communications input/output terminal; a fault generator unit generating fault information and transmitting the fault information through a fault information output terminal; and a battery cell monitoring unit coupled to the communications input/output terminal and the fault information output terminal, and configured to diagnose an operation of internal function based on the fault information transmitted from the fault generator unit and to output an internal diagnosis result value to the microcontroller unit.
