  • Patent number: 10989753
    Abstract: The present invention relates to a system for diagnosing an insulation element within a battery management system (BMS), in which an input terminal and an output terminal of an insulation element obtain a battery pack diagnosis signal that is output through a battery monitoring circuit and passes through the insulation element, and then abnormality of the insulation element is diagnosed based on a bit operation value of the obtained battery pack diagnosis signal, or an input terminal and an output terminal of the insulation element obtain a transceived communication signal and then abnormality of the insulation element is diagnosed based on a bit operation value of the obtained transceived communication signal.
    Type: Grant

  • Patent number: 10787094
    Abstract: The present invention relates to a system and a method of remotely managing a battery for a vehicle, in which electromagnetic waves emitted from a vehicle adjacent to a vehicle for management are rectified and are usable as operation power for monitoring a state of the battery of the vehicle for management, and a passive radio frequency identification (RFID) reader module installed in the vehicle adjacent to the vehicle for management obtains the state of the battery of the vehicle for management and then provides a terminal of an owner of the vehicle for management with the obtained state of the battery, thereby enabling the owner of the vehicle for management located at a remote place to recognize a charging/discharging state of the battery of his/her vehicle and the like in real time.
