Description

Standardized battery module of heap

Technical Field

The invention belongs to the technical field of battery modules, and particularly relates to a stacked standardized battery module.

Background

The above-mentioned stacked standardized battery module may also be called a modular standardized battery energy storage module, and the battery is mainly referred to as a lithium ion battery. In a household or commercial energy storage system, a plurality of battery modules are combined with an inverter (also called "system control module"), and the plurality of battery modules are generally arranged in a stacked state from bottom to top to save space.

Technical information related to battery modules, such as CN104064716B (an output structure of a lithium battery pack), CN106784481A (a horizontal-slot stacked energy storage battery bank), and CN211150699U (an AGV lithium ion battery pack), etc., is found in published chinese patent documents. As described above, in order to save space and to achieve a modular (i.e., "building block") effect, a plurality of battery modules are stacked from bottom to top, and thus, the battery modules adjacent to each other must be restrained from each other, or may fall down.

CN210429902U recommends "a sliding stacking structure of energy storage battery module", which designs a pair of grooves for the sliding strips to fit into (called as "sliding rails") at the top of the battery module, and fixes a pair of sliding strips at the bottom of the battery module, when stacking, the two adjacent battery modules are mutually matched by the pair of sliding strips and the pair of grooves to achieve the purpose of restraining each other. However, the mutual restraining ability of the battery modules is fragile, and if the battery modules are arranged in a situation with a lack of levelness or are accidentally slightly bumped, the battery modules on the upper part may slide and fall, and even accidents are caused.

CN211320187U provides "a stacked battery energy storage system", in which two adjacent battery modules (referred to as "battery modules") are fixed by fastening screws, and the problem of relative displacement between the two adjacent battery modules does not occur compared with the aforementioned CN 210429902U. However, CN211320187U has the following disadvantages: firstly, because the base is in a tray-shaped structure, the matching reliability of the battery module supported on the base, namely the battery module positioned at the lowest part, and the base is difficult to meet the expected requirement, namely the potential safety hazard of slippage exists; secondly, because the base can only bear the load and cannot accommodate the battery module positioned at the lowest part in one group of battery modules, the overall height can be increased to a certain extent, and the higher the height is, the higher the center of gravity is, so that the stability is not favorable; thirdly, since it is necessary to fix the upper and lower adjacent battery modules using fasteners such as fastening screws (paragraph 0024 of the specification), it is troublesome to stack and disassemble during maintenance. In view of the foregoing, there is a need for improvement, and for the applicant to make a useful search and design, the technical solutions described below have been made in this context.
