The invention discloses an automobile external power connection method and device, relates to the technical field of automobile power connection, and mainly aims at opening an automobile back door to carry out automobile external power connection, effectively avoiding the increase of a high-power relay, a diode and a large-power wire and reducing the development cost. According to the main technical scheme, when the whole automobile is fed, a BCM is communicated with external power supply equipment through a connecting wire, arranged outside the automobile, of the BCM so that the BCM can be powered on, the BCM obtains a target signal, and the target signal at least comprises a high-level signal; the BCM controls a back door of the automobile to be opened based on the target signal so that a storage battery can be exposed; and the whole automobile is powered on through the external power supply device communicated with the storage battery. The device is used for external power connection of the automobile.
