  • Publication number: 20240363943
    Abstract: An edge beam for a battery tray, a battery tray, a battery pack, and a vehicle are provided. The edge beam includes an edge beam body. The edge beam body defines a cavity. The edge beam body has a partition portion. The partition portion is located in the cavity. The partition portion is connected between a top wall and a bottom wall of the cavity to partition the cavity into multiple sub-cavities. The multiple sub-cavities are arranged in sequence in a width direction of the edge beam. In a direction from an upper end to a lower end of the edge beam, the partition portion inclines away from the placement groove.

  • Publication number: 20240356185
    Abstract: A battery tray assembly includes a tray and an electrically conductive member disposed in the tray. The tray includes a mounting space configured to accommodate a battery assembly, and is electrically isolated from the battery assembly. At least a portion of the electrically conductive member is located in the mounting space. One end of the electrically conductive member is connected to a potential point. When no electrically conductive medium is disposed in the mounting space, the electrically conductive member is configured to provide a first potential signal between the battery assembly and the potential point. When the electrically conductive medium is disposed in the mounting space, the electrically conductive member connects the battery assembly to the potential point through the electrically conductive medium, to provide a second potential signal between the battery assembly and the potential point.
