Example Embodiment

[0034] Example: such as Figure 1 to Figure 6 and Figure 8 As shown, a battery pack is a battery pack composed of four layers of batteries in series and parallel. The batteries on the same layer are in parallel, and the four layers are in series, such as figure 1 , From top to bottom are the busbar fixing nut 7, the positive busbar 4, the positive fixing frame 5, the first layer of single battery 1, and the network 3, the battery fixing frame 2, and the second layer of battery, the second The bottom of the three-layer battery and the fourth-layer battery are the negative electrode fixing frame 5, the negative electrode busbar 4 and the fixing screw 6.

[0035] See figure 2 The single storage battery 1 of the present invention has a cylindrical structure, and the electrodes are located at opposite ends. One end of the negative electrode is an internal threaded hole 8, and the positive electrode has a bolt 9 structure. The internal thread 8 and the bolt 9 are mutually matched, and...

Abstract

The invention discloses a storage battery which comprises monomer batteries provided with internal threads and bolts, a battery fixing frame, a parallel connection net, confluence pieces and a battery positive and negative pole fixing frame, wherein the series connection of the batteries is realized in a threaded connection manner, the parallel connection of the batteries is realized through the parallel connection net, and the battery fixing frame, the parallel connection net and the confluence pieces are provided with heat dissipation holes; and gaps are formed among the monomer batteries, and heat dissipation is directly carried out on the batteries through the gaps and the heat dissipation holes. The storage battery realizes a battery pack with high voltage and high capacity through a series-parallel connection combination of minitype column batteries, is beneficial to installation, the maintenance and disassembly of the battery pack and is good in the heat dissipation property; and the whole operation reliability of the battery pack is improved, and the storage battery is suitable for the application of large-scale power systems such as electric vehicles and stored energy.

Description

technical field [0001] The invention discloses a storage battery pack, which belongs to the technical field of storage battery manufacturing according to the International Patent Classification (IPC), and in particular relates to a battery pack in which a plurality of single cylindrical batteries are combined in series and parallel. Background technique [0002] In the prior art, when multiple batteries are used in combination, especially when multiple single cylindrical batteries are combined in series and parallel to form a large-capacity, high-voltage battery pack, welding connections are generally used, but the reliability of the connection, the connection direction and the The output current etc. is limited. Especially when forming a large battery pack, its connection direction, connection reliability, etc. are more restricted, and maintenance, disassembly, etc. will destroy the entire battery pack. The method of the patent document CN200810168497.2 adopts the shrapnel...
