1. VDA355 Battery Module

The VDA355 module is a standard size introduced by the Federation of the German Automotive Industries (VDA) and originally used as a standard module inside Volkswagen vehicles. The module size is 355*151*108 mm, which is suitable for various new energy passenger car and commercial vehicle battery packs equipped with VDA355 module size. It can also be used in energy storage, ships, mining machinery and other application scenarios. VDA355 module has good versatility and high energy density, which is suitable for high-voltage battery system of new energy electric vehicles. In China’s passenger car market, 355 modules are widely recognised . EV battery pack design are mostly based on 355 modules.

From the VDA355 standard module, prismatic lithium battery cells with different thicknesses have been developed. From The earliest 1 module (12 cells) to start, the size of a single cell: 148mm * 90mm * 26mm, 12pcs cells assembled for 1 battery module; later this size development of 2 times as thick as 148mm * 90mm * 52mm, a single module assembled with 6  battery cells; 3 times as thick as 148mm * 90mm * 78mm cell dimention ,a vda355 lithium battery module assembled of 4pcs prismatic lithium battery cell . Before 2018,  VDA355 module is the mainstream in the market. As far as the single cell is concerned, 148mm*90mm*26mm is the basic standard size. ‌
