iNRCORE’s BMS transformers resolve the key customer pain point of open failure at wire termination by using spot welding and adding post soldering processes. Once coil wound, wires are spot welded to terminals, which melts enamel wires to leads. Post soldering then prevents oxidation. Together these processes deliver a robust connection to increase reliability by avoiding open failure.

The new BMS transformers provide safety isolation and EMI noise suppression. They support serial daisy chain, isoSPI, SPI, and other applications. The transformers have an operating temperature of -40° to more than +125° Celsius and functional, basic and reinforced insulation are available.

To ensure quality, iNRCORE operates full automation for coil winding, spot welding, soldering, testing and packing processes.
