The present application relates to a battery module treatment method and system, and a computer device, a medium and a program product. The battery module treatment method provided in the embodiments of the present application is characterized by comprising: in response to determining that there is a heated battery module on a conveying line, generating an instruction for grabbing the battery module from the conveying line; determining the type of the battery module; and in response to determining that the type of the battery module is a first type, generating an instruction for placing the battery module into a standing repository for standing, wherein the first type indicates that standing needs to be performed on the battery module after heating.

Disclosed in the present application are a downward-pressing mechanism, a pressure application apparatus and a battery production device. The downward-pressing mechanism comprises a variable-distance unit and a plurality of downward-pressing members, wherein the variable-distance unit comprises a substrate and a plurality of variable-distance members sequentially arranged on the substrate in a first direction, and at least one variable-distance member can move in the first direction; and each downward-pressing member is connected to a corresponding variable-distance member, and the downward-pressing member is used for pressing a product.

The present application is applicable to the technical field of battery manufacturing apparatuses and provides a battery support mechanism (30) and a battery heating device (1). The battery support mechanism (30) includes a base (100), a drive structure (200), and two end plate support structures (300). The two end plate support structures (300) are spaced apart along a first direction on the base (100), and at least one of the two end plate support structures (300) is in transmission connection to the drive structure (200) to move along the first direction under the drive of the drive structure (200). The battery support mechanism (30) provided by the present application is configured to support a battery (50). A distance between the two end plate support structures (300) can be adjusted through the drive structure (200) according to the size of the battery (50), so as to support batteries (50) of different sizes with higher compatibility.

An energy storage apparatus (10) and an energy storage system (100) are provided. The energy storage apparatus (10) is configured to be electrically connected to a power conversion system (20), where the power conversion system (20) is capable of cooperating with M energy storage apparatuses (10), a rated output power of the power conversion system (20) is P, an energy of the energy storage apparatus (10) is Q, a duration for the energy storage apparatus (10) to discharge from a fully charged state to a fully discharged state is A, satisfying: 0.7 ≤ P/(M * Q/A) ≤ 0.99. With P/(M * Q/A) ≤ 0.99, it is ensured that the power of all energy storage apparatuses (10) cooperating with the power conversion system (20) maintains sufficient margin relative to the power of the power conversion system (20), eliminating the need for capacity supplementation of the energy storage apparatus (10) over a long period, achieving long-term reliability of the energy storage apparatus (10). With P/(M * Q/A) 2: 0.7, it is ensured that the margin of the power of the energy storage apparatus (10) relative to the power of the power conversion system (20) is not excessive, reducing power waste and improving the economic efficiency of the energy storage apparatus (10). Thus, power matching between the energy storage apparatus (10) and the power conversion system (20) is improved.

Embodiments of this application provide a battery cell, a battery, an electric apparatus, and an energy storage apparatus. The battery cell includes a housing and an electrode assembly, where the electrode assembly is accommodated within the housing, the housing is cylindrical, a height of the housing is H<1>, and a radius of the housing is R<1>. The housing includes a first end wall, a second end wall, and a side wall, where the first end wall and the second end wall are oppositely disposed along a height direction of the housing, and the side wall connects the first end wall and the second end wall. A sum of thicknesses of the first end wall and the second end wall is a, and a thickness of the side wall is b, satisfying: (R<1>-b)<2>*(H<1>-a)/(R<1>2 *H<1>)≥96%. Thus, the volumetric energy density of the battery cell is increased under a same chemical material system.

This application discloses a heating structure for heating a side plate of a battery. The heating structure includes a heating element and a heat-conducting element, where the heat-conducting element is fitted to the heating element and configured to conduct heat to the side plate of the battery. The heat-conducting element is provided with a first clearance hole capable of avoiding a protruding structure on the side plate. This application further discloses a heating bank and a battery production device.

A positioning apparatus, a battery cell manufacturing device, and an insulator positioning method. The positioning apparatus includes a positioning platform and a positioning mechanism, where the positioning platform is configured to support the insulator, and the positioning mechanism is configured to abut against at least one edge of the insulator to position the insulator. The insulator is positioned by abutting the positioning mechanism against at least one edge of the insulator, improving the positioning accuracy. This improves the relative positional relationship between the insulator and other components in cooperation when the insulator is transferred to a next station, helping improve the quality of connection between the other components and the insulator.
