We can put pouch cells into battery module frame, then do laser welding on the cell tabs to the metal sheets on battery modules, by that way we can make sure connection is firmly and good for big current pass. Then we build customized soft-link busbars to connect modules with screws. We can put the battery modules inside metal case, then we build the cell volt wires and temperature sensor wires to the multi-pins connector built on the metal case, so you can use them to connect to your BMS system.
All the cells we used in our battery pack are grade A Electric Vehicle Level Cells, which fully ensures the performance and safety of the battery pack.
Over the past 10 years, we have rich experience in customization services. Our senior engineers will give you the best solution for your confirmation according to your detailed requirements!
