Abstract

The invention provides a battery module with high safety, a battery pack and a battery cluster. The battery module comprises a base, an upper cover and a plurality of battery cell groups, wherein allthe battery cell groups are arranged between the base and the upper cover, an acquisition plate is arranged on the upper cover, and the acquisition plate is electrically connected with all the batterycell groups. According to the battery module with high safety, the battery pack and the battery cluster provided by the invention, the risk of safety accidents caused by short circuit of the cable isavoided, the length of a cable between the battery module and the battery management unit is reduced, the space utilization rate is improved, the box body material of the battery pack is arranged tobe the metal plate, reinforcing ribs are arranged, so that the battery packs can be directly stacked, a mounting frame in the prior art is saved, and the purposes of saving materials, reducing the cost, simplifying the structure, reducing the engineering quantity of mounting construction and reducing the weight of the whole energy storage system are achieved.

Description

Technical field [0001] The invention relates to the technical field of batteries, in particular to a battery module, battery pack, and battery cluster with high safety. Background technique [0002] When batteries are used in the field of energy storage, a large number of batteries need to be connected in series or in parallel to form a battery module. The battery modules are then assembled into battery packs, and then the battery packs are assembled into battery clusters. Finally, the battery clusters form a complete The energy storage unit provides external DC bus to meet the voltage requirements and power storage requirements of the user. [0003] Taking a 1MW lithium titanate energy storage container as an example, the number of batteries used can reach tens of thousands, and the number of battery modules involved has reached thousands, and there are hundreds of battery packs. In the entire energy storage container, the real-time conditions of each battery cell, such as temper...
