1. Differences between lithium battery module and PACK

　　In short, the lithium battery module is a relatively complete system, while PACK is a single component.

　　Lithium battery module:

　　Lithium battery modules are multiple lithium battery packs composed of several to hundreds of battery cells in parallel and in series. In addition to the mechanism design, a more complete lithium battery pack system can be formed by adding the battery management system and thermal management system.

　　PACK：

　　PACK means packaging, packaging and assembly. Its processes are divided into three parts: processing, assembly and packaging. PACK production line generally only needs to undertake two functions: transmission and detection. At present, semi-automatic PACK assembly lines are widely used by manufacturers, mainly for online, offline, detection, in plant transmission and packaging of PACK. The automatic integration business of power battery generally includes full automatic/semi-automatic assembly line of modules and PACK, automatic equipment integration, information acquisition and transmission (MES), and software and hardware management system of unmanned workshop.

　　2. Power lithium battery module and PACK market analysis

　　With the continuous improvement of the automatic assembly process of power battery and the popularity of high-end equipment, power battery enterprises have become increasingly aware of it. Last year, many domestic enterprises have configured fully automatic module production lines, and the production capacity and product quality have been significantly expanded and improved.

　　As far as the market demand is concerned, the battery modules and PACK production equipment form will change from the current small batch and multiple varieties to the future large batch standardization. The formulation of solutions will be the focus of battery manufacturers. At the same time, battery enterprises choose automatic modules and PACK production lines, not only for investment and return, but also for the strategic layout of long-term development of enterprises.

　　People in the industry believe that in the future, if PACK enterprises want to stand out in the future market competition, they must eliminate the traditional assembly process and production methods. At the same time, PACK manufacturers of lithium battery packs need to constantly enhance their research and development strength, improve product quality, and achieve production automation. The automatic and intelligent production mode may become an important indicator to consider the PACK lithium battery.
