Description

Technical Field

[0001] The utility model relates to the technical field of battery modules, in particular to a novel battery module with a semi-open U-shaped stepped groove. Background Art

[0002] In recent years, the energy storage industry has entered a stage of large-scale development. Battery energy storage systems have been widely used in power systems. The installed capacity of power generation, grid and user sides has gradually increased. As a key link in building a new power system, energy storage is facing unprecedented development opportunities.

[0003] The existing battery energy storage system includes an energy storage container and an energy storage battery cluster arranged inside the container. The energy storage battery cluster is assembled from multiple battery plug-ins, which are assembled from multiple battery modules. For battery modules, liquid cooling technology benefits from the ability to accurately control the temperature of the battery and ensure uniform cooling. Liquid cooling energy storage systems have gradually become the mainstream solution. Since the battery modules of the liquid cooling energy storage system are connected with liquid cooling pipelines, fire protection pipelines, power cables, and sampling communication harnesses, the structure layout of the DC side container of the energy storage system is compact and difficult to integrate. In order to avoid difficulties in on-site assembly and construction, all equipment is generally assembled and transported to the project site as a whole.

[0004] The traditional battery module installation and fixing method is that there is a support beam at the bottom, and the front panel of the battery module (or the front end of the base) has installation and fixing holes, which are fixed by bolting to the battery cluster frame. However, this installation and fixing method has disadvantages. During the whole-pack transportation of the DC side container of the energy storage system, the rear end of the battery module may be greatly bumped due to the lack of limit fixation, so that the installation and fixing bolts may loosen and fall off, which may cause damage to the battery module structure in severe cases, further causing electrical safety accidents. Therefore, a new battery module with a semi-open U-shaped step groove is proposed. Utility Model Content

[0007] As a further preferred embodiment of the technical solution: one end of the locking rod away from the battery cluster frame is fixedly connected to a turning handle.

[0008] As a further preferred embodiment of the present technical solution: a guide strip is fixedly connected to the upper surface of the supporting angle piece, and two guide grooves are symmetrically provided on the lower surface of the base plate, and the inner side walls of the guide grooves are slidably connected to the outer side walls of the guide strip.
