Claim:
1. A carrier communication method based on charging-discharging of an electric vehicle, comprising: S1: determining whether a carrier signal from a peripheral apparatus is detected at an interface harness and if yes, determining whether the carrier signal is correct, after the electric vehicle is powered on; S2: receiving the carrier signal via the interface harness, when the electric vehicle detects the carrier signal and the carrier signal is correct; S3: performing a coupling and a filtering on the carrier signal by the electric vehicle to convert the carrier signal into a standard carrier signal and demodulating the standard carrier signal into a digital signal to obtain information about the peripheral apparatus, wherein the method further comprises: setting a Serial Communication Interface (SCI) of the electric vehicle in an interrupt state when receiving the carrier signal via the interface harness; and wherein at step S1, when the carrier signal is not detected at the interface harness within a predetermined initial time, it is further determined whether the carrier signal is detected at the SCI of the electric vehicle; and if yes, execute step S2.
