Battery modules

Block type Li-ion battery modules

The block type Li-ion battery module is designed to uniform the battery module size and simplify the assembly process. Pouch cells are well held and protected in an anti-frame plastic frame block with necessary foams for vibration absorption. Here are two of metal sheet bars on above the cells and fixed to the top of frame block, cell tabs go through the metal bars and lay down for the laser welding to firmly attached to the metal bars as a parallel configuration, metal bars have screw holes for further connection among blocks. Here are extra top lids for blocks, after blocks are assembled with bus bars and wires, the plastic lid can be installed for isolation and protection but will not disturb the current connections and wires.

Cassette sheets Li-ion battery modules

The Cassette sheets frame structure hold the cells as sandwich way. We made plastic sheets which shape can exactly hold the cells and be pressed together and use the steel strips go through plastic sheets with two ends pressed by the screwed nuts. On the top area here are two of metal sheet bars for laser welding of cell tabs, bars have screws for further connection. If necessary here will be extra aluminum sheets with right shape to hold cells attach to plastic sheets, aluminum sheets can help cells improve the heat passion and enhance the strength of whole structure. Those kinds of structures are mainly used as quantity volume for big energy storage systems or big electric vehicles. READ MORE

Shrink film packaged battery modules

The shrink film package method is an easy and convenient way for building small size battery modules or battery packs. Pouch cells will be arranged together with cell tabs go through PCB converting board(s), here will be extra foams among them for necessary buffering and isolation. After cells and converting boards are firmly fixed the cell tabs will be lay down for tin welding as parallel and series configuration. If for building battery pack it will2 have BMS located and installed on the cell pack with necessary isolation foams. After that we will use PVC sheets all around the pack for protection and heat shrink film wrapped, then use heat blower to finish the whole package. READ MORE
