Embodiment Construction

[0023] like Figure 1 to Figure 5 shown. A double-layer module of a square aluminum shell battery in the present invention includes an upper module, a lower module and first and second module adapter brackets 19 and 23 . The first and second module transfer brackets 19 and 23 are strip-shaped, and are provided with long bolt passing holes, fixing holes and mounting holes. The two ends of the upper module and the lower module are respectively provided with module long bolt passing holes, module fixing holes and module mounting holes correspondingly matched with the first and second module adapter brackets 19 and 23 . The upper module, the lower module and the first and second module adapter brackets 19, 23 between them are fixed as a whole through fixing holes, module fixing holes and screws 20 . The upper die set, the lower die set and the first and second die set transfer brackets 19, 23 between them are fixedly connected with the battery box through the long bolt passing h...

Abstract

The invention is a square aluminum shell battery double-layer module, belonging to the field of square aluminum battery PACK technology. The problems of poor versatility, low degree of modularity, limited application range and high product cost of an existing two-layer module are mainly solved. The square aluminum shell battery double-layer module is characterized in that the module comprises an upper module, a lower module and first and second module adapter brackets, the module adapter brackets are provided with long bolt through holes and fixed holes, two ends of the upper module and the lower module are provided with module long bolt through holes and module fixed holes, the upper module, the lower module and the module adapter brackets between the upper module and the lower module arefixed by screws to form a whole body, and the upper module, the lower module and the module adapter brackets between the upper module and the lower module are fixedly connected to a battery box through long bolts. The square aluminum shell battery double-layer module has the characteristics of small size, light weight and the great improvement of the superiority of a square aluminum shell batterycompared with an industrial module frame and is mainly used for a double-layer aluminum shell battery module of a new energy automobile.

Description

technical field [0001] The invention belongs to the technical field of square aluminum case battery PACK, in particular to a structure of a novel square aluminum case battery double-layer module, which is used for various double-layer aluminum case battery modules. Background technique [0002] A typical square aluminum lithium battery, the main components include: top cover, casing, positive plate, negative plate, laminated or wound diaphragm, insulators, safety components, etc. Among them, there are two safety structures, NSD acupuncture safety device; OSD overcharge protection device. [0003] The packaging reliability of the prismatic battery is high; the energy efficiency of the system is high; the relative weight is light and the energy density is high; the structure is relatively simple and the expansion is relatively convenient. The system structure is relatively simple, which makes it possible to monitor the monomers one by one; another benefit brought by the simpl...
