The invention provides a vehicle energy flow analysis method, device and system and a vehicle, and relates to the technical field of pure electric commercial vehicles. The vehicle energy flow analysis method comprises the following steps: acquiring operation data of a plurality of systems on a target vehicle under various working conditions; processing the operation data of the plurality of systems on the target vehicle under the plurality of working conditions by using an energy flow calculation model corresponding to the target vehicle so as to obtain energy flow distribution data under the plurality of working conditions; determining an optimization feasibility index value of each system in the plurality of systems according to the energy flow distribution data under the plurality of working conditions; and determining a system to be optimized from the plurality of systems according to the optimization feasibility index value of each system in the plurality of systems so as to optimize the system to be optimized. Through the method, the energy consumption of the whole vehicle can be efficiently and accurately optimized, so that the optimized vehicle is more energy-saving and consumption-reducing.
