The invention discloses a vehicle energy flow control method and device and a vehicle. The method comprises the steps: acquiring and recording the current actual power, the current remaining availablepower and the current request power of the vehicle; determining a current energy state of the vehicle according to the current residual available power and the current request power; acquiring the limit power of the vehicle at the last moment, and determining the current energy flow control mode of the vehicle according to the limit power at the last moment and the current residual available power; according to the current energy state, the current energy flow control mode, the current actual power and the current remaining available power, determining the current limit power variation of thevehicle; obtaining and recording the current limit power of the vehicle according to the current limit power variation and the limit power at the last moment; and controlling the energy flow of the vehicle according to the cu
