The charging device includes a first charging interface and a second charging interface. The first charging interface includes a first auxiliary power supply contact and a first direct current power supply contact. The second charging interface includes a second auxiliary power supply contact and a second direct current power supply contact. The charging device is configured to detect a first voltage signal of the first auxiliary power supply contact and a second voltage signal of the second auxiliary power supply contact; and enable the first direct current power supply contact and the second direct current power supply contact based on the first voltage signal and the second voltage signal to simultaneously charge the electric vehicle.",
