The invention discloses a vehicle power over-limit fault detection method and device, a vehicle and a storage medium. The method comprises the following steps: reading the actual power and limiting power of a to-be-detected part of the vehicle at a current moment T, and obtaining first actual power and first limiting power; when the difference value obtained by subtracting the first limiting powerfrom the first actual power is larger than a first threshold value, determining whether the actual power of the to-be-detected part at the current moment T responds to the limiting power or not according to the actual power reduction rate and the limiting power change rate of the to-be-detected part at the current moment T; and when the actual power of the to-be-detected part at the current moment T does not respond to the limiting power and the actual power of the to-be-detected part at each moment in a time interval [T-t, T] before the current moment T does not respond to the limiting power, determining that the to
