Problems solved by technology

At present, in the field of new energy vehicles, the method used to increase energy density and reduce costs is demodularization (CTP technology), but this technology cannot be copied and applied to the field of energy storage. Most of the energy storage field still uses traditional battery-battery modules. -Composite design of battery pack-battery cluster

Abstract

The invention discloses an energy storage battery cluster with a simplified structure, which comprises a battery rack, the inner surfaces of the two sides of the battery rack are provided with battery modules and battery module occlusion grooves, a battery module layer support is arranged between the inner surfaces of the two sides of the battery rack, and the outer surface of the upper end of the battery module layer support is provided with a battery cluster body. According to the energy storage battery cluster with the simplified structure, after the lithium batteries form the module, the module is directly installed on the battery rack of the battery cluster, the weight of the module is directly borne by the reinforcing beams of the battery rack, and a bottom shell in a traditional method is omitted. Occlusion structures are arranged between the modules as well as between the modules and the battery rack, so that the structure is stable, and easy dislocation caused by shaking or external impact is avoided. Due to the fact that no closed pack shell is arranged outside the module, the heat dissipation area of the module is increased, and the heat dissipation efficiency is higher. A large module structure is adopted, the structure is simplified, meanwhile, the material cost and the manufacturing cost are reduced, and meanwhile installation and maintenance are convenient.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a structurally simplified energy storage battery cluster. Background technique [0002] At present, in the field of large-scale energy storage of lithium-ion batteries, lithium battery cells are basically combined into modules in series and parallel, and then the modules are assembled into battery packs in series or in parallel, and the battery packs are then assembled into battery packs through The battery clusters are formed in series and parallel, and then multiple battery clusters are fixed in the container to form a large-scale energy storage system. Since battery modules and battery packs require a large amount of structural materials, the weight of the entire energy storage system is increased. The production cycle of battery modules and battery packs is long and the process is complex, which also reduces the production efficiency of the entire energy storage system, in...
