Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

Abstract

The invention relates to the field of a battery, and specifically discloses a battery module. The battery module comprises a battery pack and an external fixed body, wherein the battery pack is formed by a plurality of cylindrical single batteries arranged in parallel; the external fixed body is fixed outside the battery pack; the external fixed body comprises a first side surface and a second side surface; the first side surface is provided with a first concave-convex structure; and the second side surface is provided with a second concave-convex structure which can be jogged with the first concave-convex structure of the adjacent battery module. According to the battery module provided by the invention, by setting the concave-convex structures on the first and second side surfaces, the concave-convex structures of the adjacent battery modules can be jogged mutually, so that all battery modules in the battery assembly can be formed into a whole body; when the whole body suffers from shaking or vibration, the battery modules are not displaced easily, so that the battery modules are firm and reliable in fixation; and in addition, by virtue of the concave-convex structures, the dead-angle positions of the cylindrical single batteries can be fully utilized, so that the space in the battery module is fully utilized, and the space utilization rate is improved. The invention also provides a battery assembly comprising the battery module.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery module, a preparation method thereof, and a battery assembly. Background technique [0002] At present, the demand for battery modules in the new energy and energy storage industries is increasing. Generally, the battery modules are square, and the battery modules are basically fixed on the bottom plate alone, and the battery modules are only electrically connected through conductive strips. In this way, the battery modules cannot be effectively formed as a whole, and the battery modules may not be firmly fixed when shaken or vibrated by the outside. The inside of the battery module generally contains a number of cylindrical single cells. The battery module is square, and the space of the battery module cannot be fully utilized, and the effective utilization rate of the space is low. Contents of the invention [0003] Based on this, it is necessary to provide a battery modu...
