A connection structure for assembled batteries, including a battery pack casing and four single cells, the four single cells are placed in the battery pack casing in two rows and two columns, and the four single cells are connected in series through conductors to form a In the battery pack, the conductor is made of a spring, and the spring is arranged between the single battery and the battery pack case, and between two adjacent single batteries. The present invention uses springs as conductors to connect four single cells in series. At the same time, the elastic force of the springs and the weight of the single cells are used to form a stable and reliable mechanical connection, thereby eliminating the need for welding methods, reducing energy consumption, saving precious metals, and improving energy efficiency. Improve production efficiency, eliminate environmental pollution in the production process, and achieve the purpose of energy saving and environmental protection. The technical indicators of the battery pack have reached or exceeded the performance of the original technology products, and the test data in the test of storage and transportation in the special harsh climate environment have exceeded the performance of the original connection technology products, and the effect is obvious.
Description
[0001] Technical field: [0002] The invention relates to the field of electricity, in particular to battery technology, in particular to a connection structure of an assembled battery. [0003] Background technique: [0004] 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. [0005] Invention co...
