Abstract: A battery cell, a battery module, a battery pack, an energy storage system, and an electric vehicle. The battery cell includes one or more stress sensors. The stress sensors are located on the explosion-proof valve and face outside a housing of the battery cell, or the stress sensors are located on the explosion-proof valve and face inside a housing of the battery cell. Each stress sensor is configured to detect stress that is inside the battery cell and that acts on a corresponding position on the explosion-proof valve, and the one or more stress sensors are configured to transmit all obtained electrical signals to processor. The processor determines a faulty target battery cell based on one or more received electrical signals.

Abstract: A method and device for displaying reference content, and a storage medium thereof are provided. In some embodiments, the method includes displaying a first interface in response to an operation of enabling the first interface; displaying multiple second interfaces on the first interface in a form of floating window in response to an operation of enabling reference content, the multiple second interfaces including different reference content respectively; and displaying, in response to an operation of selecting a second interface from the multiple second interfaces, the selected second interface on the first interface in an overlaying manner. The formation arranging efficiency and communication efficiency between game players and the reference content can be improved by the above technical solution.
