Abstract: A battery tray assembly (100), a battery pack, and a vehicle (1) are provided. The battery tray assembly (100) includes a tray (110) and an electrically conductive member (130). The tray (110) defines a mounting space (110a) configured to accommodate a battery assembly (200) and the tray (110) is electrically isolated from the battery assembly (200). The electrically conductive member (130) is provided in the tray (110) and at least partially located in the mounting space (110a). One end of the electrically conductive member (130) is configured to be connected to a preset potential point. When no electrically conductive medium is present in the mounting space (110a), the electrically conductive member (130) is configured to provide a first potential signal between the battery assembly (200) and the preset potential point. When the electrically conductive medium is present in the mounting space (110a), the electrically conductive member (130) brings the battery assembly and the preset potential point into conduction by means of the electrically conductive medium, to provide a second potential signal between the battery assembly (200) and the preset potential point. The first potential signal and the second potential signal are used to characterize whether the electrically conductive medium is present in the mounting space (110a).
