| Zusammenfassung: | The invention discloses an electric vehicle and a sintering detection method and detection device for a direct current charging contactor of the electric vehicle, and the method comprises the steps: determining a sintering detection result of the direct current charging contactor through detecting the voltage of a direct current charging port of the electric vehicle when the direct current charging of the electric vehicle is finished; when the electric vehicle is powered on, if it is determined that sintering detection of the direct-current charging contactor is not completed according to the sintering detection result of the direct-current charging contactor, sintering detection is conducted on the direct-current charging contactor again by detecting the voltage of the direct-current charging port of the electric vehicle when a direct-current charging port cover of the electric vehicle is in a normal closing state. According to the sintering detection method, the sintering state of the direct current chargin |
