Developed for 1P12S 58Ah NMC battery modules, with a structure matched to the VDA355 module platform.
Busbars, FPC sensing circuits, insulation components, and connection interfaces are integrated into one compact assembly.
The integrated FPC supports individual cell-voltage sensing and NTC temperature monitoring for connection to the BMS.
FPC routing, busbar arrangement, output terminals, connectors, and mounting details can be customized for the module design.
