Abstract

The invention discloses a soft package power lithium ion battery module. The soft package power lithium ion battery module comprises a module frame, a plurality of bar lithium ion battery cells, a plurality of silica gel bars, a panel and a busbar group, wherein the silica gel bars are arranged among the lithium ion battery cells in a clamped manner; the lithium ion battery cells are arranged inside the module frame along the length direction and the width direction of the module frame side by side respectively; lugs of the lithium ion battery cells are linearly arranged into a lug string andare connected into positive and negative electrodes of the soft package power lithium ion battery module through the busbar group; the panel is installed at one end of the module frame; and the busbargroup is arranged on the panel. Compared with the prior art, the soft package power lithium ion battery module provided by the invention is relatively high in specific strength and relatively small in overall volume, and has the characteristics of high heat resistance, high corrosion resistance, high shock resistance, convenient and simple processing, convenient installation, low production cost,economy and environmental protection and the like.

Description

technical field [0001] The invention relates to the field of battery technology, in particular to a soft-pack power lithium-ion battery module for an electric vehicle and an assembly method thereof. Background technique [0002] Due to the advantages of high energy density, good safety, light weight, and long cycle life, lithium-ion power batteries have been widely used in energy storage systems. Especially in the field of electric vehicle energy storage, lithium-ion power batteries have become the preferred battery type. Due to the low voltage and small capacity of most lithium-ion power battery cells at present, they cannot meet the power demand of the whole vehicle. Therefore, it is necessary to connect multiple single cells in series and parallel to form a battery module that can meet the power demand of the whole vehicle. However, the existing soft-pack power lithium-ion battery modules are designed for vehicle models and are targeted. Limited by fixed molds, only a fi...
