Abstract

The invention discloses a high and low voltage separated type aluminum laminated battery module. The high and low voltage separated type aluminum laminated battery module is composed of multiple battery assembly units. Each battery assembly unit comprises a battery fixing frame (3) and a battery cell (1), wherein an insertion piece installation port (31) is formed in the side face of the battery fixing frame (3), and an insertion pin (2) is installed in the insertion piece installation port (31) and welded to a battery tab. Fixing and clamping grooves (32) open in the same direction are formed in the side edges of the battery fixing frames (3), and connection of the multiple battery assembly units is achieved by clamping module fixing bars (5) in the fixing and clamping grooves (32). The battery module is standardized in structure, high in reliability, convenient to assembly and high in structural strength, and production efficiency can be improved greatly.

Description

technical field [0001] The invention belongs to the technical field of battery packs, and more specifically relates to a soft pack battery module with high and low voltage separation. Background technique [0002] Pure electric vehicles are an important direction for the development of new energy vehicles. In order to ensure sufficient cruising range, pure electric vehicles require higher and higher energy density of battery packs. Soft pack batteries have become an important direction for the development of next-generation battery modules due to their advantages such as small size, high specific energy, good safety, and flexible design. [0003] In the prior art, the pouch battery is installed in the battery fixing frame, and multiple batteries are fixed with long bolts after close contact with the battery fixing frame. Due to the length and fixing method of the fixing bolts, the efficiency of module assembly is low and wastes space. ; There are many connection points bet...
