The invention discloses a high-voltage power-on fault judgment method for a pure electric vehicle, a terminal and a storage medium, belongs to the technical field of new energy, and proposes that the state of a relay, the state of a power battery, the state of a high-voltage loop and the state of part of high-voltage components need to be monitored in the high-voltage power-on process of the electric vehicle. Detailed judgment is made for possible faults, the sequence of the relays is clearly explained, and message communication among the controllers in the power-on process is stipulated. Relay states, power battery states, high-voltage loop states and part of high-voltage component states need to be monitored in the high-voltage power-on process of the electric vehicle, detailed judgment is made for possible faults, and the sequence of the relays is clearly explained. And message communication among the controllers in the power-on process is regulated.
