Why is EMI control more critical in BMS than in many other automotive subsystems?

BMS electronics operate in close proximity to high-voltage battery cells, high-current busbars, and sensitive voltage-sense lines. Magnetic flux leakage and switching noise from DC-DC inductors can couple into these sensing paths, producing false readings, communication errors, or even triggering protection mechanisms. In addition, battery packs are often enclosed metal structures that can amplify certain resonances. Shielded or molded inductors with controlled magnetic flux paths significantly reduce radiated and conducted EMI, helping the entire battery system meet automotive EMC requirements while maintaining measurement accuracy and system stability.
