Battery Management System

Bourns Battery Management Systems (BMS) manage the state of health (SoC) while charging and discharging battery systems. BMS components feature shunt resistors, high-voltage signals, power transformers, and shielded power inductors. Current sense resistors are AEC-Q200 qualified with a continuous current of 1000A and a low 50µΩ resistance. Bourns signal transformers include common-mode chokes for noise rejection for BMS applications. The shielded power inductors and high creepage high clearance (HCT) transformers are suitable for automotive power conversion, DC-DC converters, power supplies, and communication electronics.
