Embodiment Construction
[0024] 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.
[0025] Such as Figure 1 to Figure 3 The battery module shown includes a bottom plate 1, on which a plurality of card slots 11 are arranged, and there is a distance between two adjacent card slots 11, and a battery 2 is arranged in each of the card slots 11 , and two or more adjacent batteries 2 are connected by aluminum plate 3, and the space between the slots 11 is used to form a cooling air duct and an expansion space between the batteries 2, thereby increasing the number of batteries 2 and battery modules. The reliability of the group, and use the aluminum plate 3 to choose to connect adjacent...

The invention provides a high-reliability battery module and a battery pack; the battery module comprises a bottom plate, and a plurality of clamping grooves are formed in the bottom plate. Accordingto the battery module with high reliability and the battery pack provided by the invention, a space with heat dissipation and expansion functions is formed between batteries; the aluminum plates on the same battery module are positioned and mounted in a welding manner; therefore, the structural complexity of the battery module is reduced, the grouping efficiency is improved, the single module weight is reduced, the fixed connection between the battery module and the box body is realized, and the battery module is convenient to mount and dismount. A flame-retardant plastic box is employed, so the overall quality of the battery pack box is reduced while the installability and the overall strength are ensured; meanwhile, a wiring terminal is arranged at one end of the box body, and a coolingfan is mounted in the space of a mounting terminal, so the space utilization rate is increased, the cooling efficiency of the box body is improved, the reliability of the battery pack in an application scene with high heat productivity is improved, and the pack can be used for frequency modulation and peak regulation.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a highly reliable battery module and battery pack. Background technique [0002] When assembling the existing battery packs, the batteries are directly attached to each other and put side by side into the box to complete the assembly. The aluminum plates between adjacent batteries are fixed on the batteries by bolting or welding. For large battery packs, overall welding and bolted connections are prone to weak connections, complex processes and low grouping efficiency, and the existing battery pack boxes are all made of sheet metal structures, which are heavy and inconvenient transport. Contents of the invention [0003] In order to solve the technical problem of low battery heat dissipation efficiency in the battery pack in the prior art, a highly reliable battery module and battery pack are provided that reduce the number of bolt connections and reduce the structural compl...
