Abstract

An assembled battery connection structure comprises a battery pack shell and four single cells. The four single cells are placed inside the battery pack shell in an arrangement mode of two rows and two columns. The four single cells are connected in series through conductors to form a battery pack. The conductors are composed of springs, and the springs are arranged between a single cell and the battery pack shell and between two adjacent single cells. According to the invention, the springs are used as the conductors to be connected in series so as to connect the four single cells. Meanwhile, stable and reliable mechanical joint is formed by elastic force of the springs and weight of the single cells. Thus, a welding method is not required, energy consumption is reduced, precious metal is saved, production efficiency is raised, environmental pollution is eliminated during the production process, and the purpose of energy conservation and environmental protection is achieved. Each technical index of the battery pack reaches even exceeds performance of a product produced by an original technology; each detection data during storage and transportation in a special harsh weather environment exceeds performance of a product produced by an original connection technology; and effects are obvious.

Description

Technical field: [0001] The invention relates to the field of electricity, in particular to battery technology, in particular to a connection structure of an assembled battery. Background technique: [0002] In order to store more electric energy, commonly used 4R25 single cells need to be combined into battery packs. In the prior art, the connection process of 4R25 type combined battery is as follows: a single battery is welded with wire (copper wire) and tin to form a combined battery pack in series. Specifically, each battery cell is welded on the side of the negative electrode with tin A wire, and then weld the other end of the wire to the positive electrode of another single battery, so that four single batteries are processed in series to form a combined battery. The above method consumes a lot of energy and precious metals, has low production efficiency, and produces a lot of environmental pollution during the production process. Invention content: [0003] The pu...
