  • Patent number: 11862816
    Abstract: A battery pack includes battery cells and an interconnect board assembly (ICBA) having a dielectric ICB and parallel busbars. A cell tab protrudes from an edge of the cells and joined to the busbars. A dielectric ICB is connected to the busbars at one distal end of the busbars. The dielectric material of the ICB is overmolded onto another distal end such that the ICB wraps around the busbars to form overmolded ends. The overmolded ends are received within a pocket of a bracket to form direct parallel cooling paths to a heat sink. A method of manufacturing the battery pack includes arranging the busbars in parallel, overmolding dielectric material onto ends of the busbars to form overmolded ends, and attaching the busbars to a plastic ICB formed from the dielectric material. The ICBA is then attached to the bracket and cells.

    Abstract: A system includes a user equipment (UE) traveling at least at a predetermined velocity. The UE is in RRC_INACTIVE state since time T. The system further includes at least a first base station and a second base station. The first base station receives an RRC_INACTIVE state message from the UE. The RRC_INACTIVE state message includes a location and a velocity of the UE, and a time-lapse, which is an elapsed duration since T. In response to a paging message from a core network, the first base station predicts a location of the UE. In response to the UE being within range of the first base station, the first base station sends the paging message to the UE. In response to the UE being within range of the second base station, the first base station sends a request to the second base station to send the paging message to the UE.

  • Patent number: 11858354
    Abstract: An emergency disconnect circuit for use with a high-voltage (HV) bus of a battery electric system, e.g., aboard a mobile system, includes a pyrotechnic switch and a manual switch. The pyrotechnic switch configured irreversibly opens in response to an electronic triggering signal to disconnect an HV battery pack from the HV bus in a first manner. The manual switch is arranged on a low-voltage (LV) bus in series with and between the pyrotechnic switch and an LV power supply. Transition of the manual switch from an open position to a closed position connects the LV power supply to the pyrotechnic switch. This causes the LV power supply to discharge the triggering signal to the pyrotechnic switch. When used aboard a mobile system, an electronic monitoring unit generates the triggering signal in a second manner in response to a threshold impact event.
