Perhaps Switching in the inverters of the EV will generate harmonics that are in the 540-1700khz AM range. Pulses of current in a wire between inverter and motor radiate fields which are then picked up by AM radio antenna. Because AM is amplitude modulation it is more susceptible to interference by a signal on the same frequency, whereas an FM station uses a band of frequencies to encode the information instead of the magnitude of a carrier.
