The present application discloses a high-voltage input under-voltage fault detection method for an electric vehicle, a device and a computer storage medium. The method includes obtaining an internal voltage of a target component of the electric vehicle after detecting that a battery pack of the electric vehicle is powered on with the high voltage and before the target component is powered on with the high voltage, and determining whether the internal voltage is less than or equal to a preset voltage value. If yes, the method determines that the target component has the undervoltage fault for high voltage input. In this way, after the battery pack of the electric vehicle is powered on with the high voltage and before the target component is powered on with the high voltage, it can accurately detect whether the target component has an undervoltage fault for high voltage input, which solves the problem in the prior art that the undervoltage fault can only be detected when the target component is in the working state, improves the convenience of management and maintenance of the electric vehicle, and improves the user experience.
