The invention provides an electric vehicle high-voltage control method and device and an electric vehicle, and relates to the technical field of electric vehicle control. The high-voltage control method for the electric automobile comprises the steps that under the condition that the electric automobile is in a high-voltage connection state or a high-voltage starting state, if one of the following items is obtained, the electric automobile is controlled to be powered off at a high voltage; the gear of the electric automobile is in a parking gear and the speed of the electric automobile is smaller than a preset speed within a preset duration. According to the scheme, emergency high-voltage cutoff of non-inductive starting inside or outside the vehicle can be achieved.
