Abstract

The invention discloses a lithium ion battery module structure including a top cover, a bottom shell, a cell module, a BMS management module and a PCB transition board. The cell module is positioned and connected to the bottom shell. Cell units inside the cell module are electrically connected among each other through the PCB transition board. Electrode lugs on the cell units are provided with copper lining pieces. Copper foil welding pads, which are corresponding to the cell units one-to-one, are arranged on the PCB transition board. Cell unit connecting clamps are welded onto the copper foil welding pads in a manner of being tightly-clampingly matched with the copper lining pieces. A module supporting plate is bond to a side surface of the cell module and is provided with the BMS management module. The top cover covers the PCB transition board and is integrated with the bottom shell in a manner of buckling connection. The lithium ion battery module structure is optimized, can reduce assembling process, can reduce labor intensity, can improve production efficiency, and can achieve automatic production in batches.

Description

technical field [0001] The invention relates to the technical field of lithium ion batteries, in particular to a lithium ion battery module structure. Background technique [0002] The existing lithium-ion battery market has become increasingly mature, and the scale of various manufacturers is also increasing. The grouping process of soft-packed cells is complicated, and the safety and stability of the grouped batteries cannot be guaranteed, resulting in a generally high return rate of batteries. At the same time, complex processes cannot be produced automatically, requiring a large number of employees to operate, and the production cost is too high, so that the market price of lithium batteries is too high, and the market cannot be expanded. [0003] The announcement number is CN202585590U, and the announcement date is December 5, 2012. The Chinese patent document discloses a power supply module structure for electric vehicles, including two pressure plates and seve...
