Abstract: The present disclosure provides a battery module. The battery module includes a plurality of batteries that are stacked and two end plates disposed at two ends of the plurality of batteries in a stacking direction of the batteries. The battery module further includes a fixing strap, which includes a strap-shaped body and an elastic fixing part. The strap-shaped body surrounds the plurality of batteries and the end plates and defines a gap. The elastic fixing part is disposed in the gap and connected to the strap-shaped body. The elastic fixing part, together with the strap-shaped body, can provide an expansion space for the battery module with a certain restraint. In this way, the deformation of the battery module can be suppressed, and the battery module is protected from being damaged by a shear force of the strap-shaped body, thereby improving reliability of the battery performance.

Abstract: This application provides a battery module and a device, and relates to the technical field of batteries. The battery module includes a battery cell, a circuit board, a temperature sensor, and a fixing component. The circuit board is disposed at a top of the battery cell and electrically connected to the battery cell. The temperature sensor is disposed at the top of the battery cell and configured to measure a temperature of the battery cell. The temperature sensor is electrically connected to the circuit board. The fixing component includes a fixing portion and a rotation portion. The fixing portion is fixed to the top of the battery cell. The rotation portion is screwed into the fixing portion so that the temperature sensor is pressed against the battery cell tightly. This application can improve accuracy of temperature collection of the battery cell.

Abstract: Embodiments relate to the technical field of batteries, and provide a battery module, a battery pack, and a vehicle to optimize a structure of the battery module. The battery module includes a battery, a harness plate, a circuit board, a compression element, and a temperature collection assembly. The battery includes a top cover. The harness plate is disposed on a top outer side of the top cover. The compression element is connected above the harness plate. The temperature collection assembly includes a thermistor. The thermistor is electrically connected to the circuit board, and the thermistor is disposed between the top cover and the compression element. The compression element presses the thermistor so that the thermistor is pressed against the top cover. The battery module provided in the foregoing solution shortens a temperature collection path and makes measurement accurate.

Abstract: The present disclosure provides a battery module and a battery pack. The battery module includes: a battery unit array structure including a plurality of battery units stacked along a length direction and having two opposite end portions along the length direction and two opposite side portions along a width direction; and at least two connecting components spaced apart from each other, each of them having a first holding portion and a second holding portion. In each connecting component, the first holding portion is located at one end portion and connected to a part of the end portions, and the second holding portion is located at one side portion and connected to a part of the side portion. The holding portions have the smaller volume and weight, which can improve the energy density and space utilization of the battery module and the battery pack.
