Embodiments of this application provide a testing apparatus, configured to test a battery and including a test body and a first door body. The test body may include an accommodating cavity for accommodating the battery, and an opening. The opening may communicate with the accommodating cavity, and the first door body may be connected to the opening and capable of moving relative to the opening. The first door body may have a first state and a second state; in the first state, the first door body may block a part of the opening; and in the second state, the first door body may seal the opening.

Testing apparatus

This application relates to a battery tray, a battery testing module, a battery testing system and a battery production system. During the testing process, the battery is placed on a tray body and electrically connected to a connection terminal, so that the test end of the battery can be transferred to a test connection bar. When being connected to the charge and discharge device, only the connection terminal of the test connection bar needs to be connected in a contact manner to achieve electrical connection between the battery and the charge and discharge device.

Battery tray, battery testing module, battery testing system and battery production system

The present application discloses a method, apparatus, device, and system for monitoring battery pack safety. The method includes: obtaining, based on obtained stress data of a battery pack in an electric vehicle, stress energy information of the battery pack; determining a target-level alarm condition based on the stress energy information and sending corresponding alarm information, where the target-level alarm condition is a level of alarm condition in preset N levels of alarm conditions that the stress energy information satisfies, an ilevel of alarm condition indicates that there are moccurrences of impact energy represented by the stress energy information that is within an ienergy threshold range, and a lower limit of the ienergy threshold range of the ilevel of alarm condition is greater than an upper limit of an (i−1)energy threshold range of an (i−1)level of alarm condition, and m<m.

Method, apparatus, device, and system for monitoring battery pack safety and storage medium

A gap inspection apparatus and a gap inspection method are disclosed. The gap inspection apparatus is configured for a wound battery cell, where in a height direction of the wound battery cell. The gap inspection apparatus includes: an X-ray source and an X-ray detector and a bearing mechanism located between the X-ray source and the X-ray detector. The bearing mechanism includes at least one accommodating groove, the accommodating groove is configured to accommodate the wound battery cell, and the height direction of the wound battery cell crosses a first direction in which the X-ray source points to the X-ray detector. The X-ray source is configured to irradiate an arc-shaped area of the wound body portion, and the X-ray detector is configured to obtain an imaging image of the irradiated arc-shaped area, so as to obtain a gap value between two electrode plates within the arc-shaped area.
