Does the pulse group test (5kHz repetition frequency) on the BMS control board cause relays to mis-trigger?

In pulse burst testing, 5kHz fast transient pulses can easily couple through the relay drive circuit or power supply, leading to false triggering. Suppression methods include adding a series resistor and a small capacitor to ground in parallel to form a low-pass filter in the relay drive circuit. A freewheeling diode or an RC snubber circuit can be added in reverse parallel across the relay coil to suppress transients. Additionally, a ferrite bead and electrolytic capacitor can be added to the coil power input for filtering. Using optocouplers or relay driver ICs for isolated driving can more effectively cut off interference paths and prevent malfunctions caused by noise in the drive signal or power supply.
