Does the equalization circuit on the BMS control board generate radiated interference in a specific frequency band when it is working?

When equalization circuits, especially active equalization circuits, operate at high frequencies, their high-frequency switching generates radiated interference in specific frequency bands, concentrated at the switching frequency and its harmonics. The main sources of this interference are the equalization inductor or transformer and the loop formed by the high-speed switching MOSFET. Suppression measures include connecting a small resistor in series with the MOSFET gate to mitigate the switching edge. Shielded magnetic cores or copper foil shielding should be used for the equalization inductor. The equalization circuit should be centrally located and kept away from sensitive circuits, with partial shielding used if necessary. Ferrite beads should be used for filtering the equalization power input line. By controlling the switching speed, shielding the radiation sources, and providing spatial isolation, the radiated interference from the equalization circuit can be effectively suppressed.
