  • Patent number: 12603349
    Abstract: A battery module including: a battery cell stack including a plurality of battery cells; a housing for the battery cell stack; and a heat conductive resin layer formed on the bottom part of the housing. The heat conductive resin layer includes a first heat conductive resin layer and a second heat conductive resin layer. The first heat conductive resin layer is formed adjacent to the front surface of the battery cell stack, and the second heat conductive resin layer is formed adjacent to the rear surface of the battery cell stack, and at least a part of the first heat conductive resin layer and at least a part of the second heat conductive resin layer are spaced apart from each other.

  • Publication number: 20250327866
    Abstract: A battery diagnosis apparatus located within a battery system may include at least one processor; and a memory configured to store at least one instruction executed by the at least one processor. The at least one instruction may include diagnosing whether a battery is abnormal based on at least one battery state value during a process of charging and discharging the battery; generating a first diagnosis result when an abnormality occurs in the battery; verifying validity of the first diagnosis result based on whether a door provided on a container accommodating the battery is opened or closed; and outputting the first diagnosis result as a final diagnosis result when the first diagnosis result is determined to be valid.
