Mechanical Support: Modules are housed in sturdy frames to provide structural integrity and protect cells from physical damage. A battery pack consists of multiple battery modules integrated to form a complete energy storage solution. Packs are engineered to deliver the required power and energy for specific applications.
This is where battery modules come into play. Cells are initially connected and housed within frames to form these modules. Various battery assembly equipment are used to form packs from cells and provide an additional layer of protection, shielding cells from external factors such as heat and vibration.
