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.
