Embodiment Construction

[0043] Such as Figure 1 to Figure 19 As shown, an embodiment of a battery grouping module, the battery grouping module in this embodiment includes a battery unit 1, a cover plate 2, a binding baffle 3, a binding band 4, a conductive bar 5, an insulating grid assembly 6, a wiring Terminal 7 and insulating end cap 8.

[0044] A plurality of battery units 1 are arranged in sequence along the left and right directions. Each battery unit 1 includes a heat dissipation protection plate 9 and a battery 10 fixed in the heat dissipation protection plate 9 . Each battery 10 has a positive tab and a negative tab respectively. According to the number of batteries contained in the battery unit, the battery unit can be divided into a single battery unit and a multi-battery unit. The heat dissipation protection plate of the single battery unit accommodates a single battery, and the heat dissipation protection plate of the multi-battery unit in this embodiment Contains two batteries. In thi...

Abstract

The invention relates to a battery grouping module, which includes a plurality of battery units arranged in sequence along the left and right directions and bound and fixed together by binding straps, each battery unit includes a heat dissipation protection plate and a battery, and the battery grouping module also includes a The conductive bar above the battery unit and corresponding to the tab on the battery is conductively connected. An insulating grid assembly is interposed between the conductive bar and the battery unit. The insulating grid assembly is fixedly assembled with the conductive row and the heat dissipation protection plate through the tab hole electrically connected with the conductive row. When the insulating grid assembly is fixedly assembled with the conductive row and the battery unit, the tab perforation on the insulating grid assembly is used to position the tab to ensure the welding posture and position of the tab and the conductive bar during welding, improving the battery life. Overall assembly quality of grouped modules.

Description

technical field [0001] The invention relates to a battery group module. Background technique [0002] With the increasing demand for environmental protection and energy pressure, for the automotive industry, the use of high-power battery packs as a power system to replace or partially replace fuel engines has become a solution and development direction. Lithium-ion battery is a new generation of battery with high technological content and wide application, and is called "the most promising chemical power source". Soft-pack lithium-ion battery is a high-performance battery composed of positive and negative electrodes, electrolyte, aluminum-plastic film casing, etc. It can be charged and discharged at a large rate, and has a long cycle life. Made of aluminum-plastic composite film wrapped and bundled, the production process is relatively simple, the cost is low, and the market potential is huge. [0003] In the Chinese invention patent application publication number CN104319...
