Abstract

The embodiment of the present invention discloses a vehicle energy control method, device, vehicle and storage medium. The method includes: acquiring the remaining power of the power battery at the current moment, and determining the fuel cell engine's first fuel cell engine according to the remaining power and the threshold of the remaining power A candidate output power value; based on the thermal management power threshold of the fuel cell engine, the output power per unit time and the minimum output power, determine the second output power candidate value of the fuel cell engine; according to the required power of the vehicle and the maximum discharge of the power battery power, the first output power alternative value and the second output power alternative value to determine the target output power of the fuel cell engine at the current moment; The maximum working power determines the target working power of the power battery at the current moment. The embodiment of the invention improves the energy utilization rate of the whole vehicle and reduces the energy consumption rate of the whole vehicle.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electric vehicle power, and in particular to a vehicle energy control method and device, a vehicle and a storage medium. Background technique [0002] Fuel Cell Electric Vehicle (FCEV) has the advantages of zero emission and high efficiency. However, if the fuel cell system is set alone, there are some shortcomings, such as slow dynamic power response, which cannot meet the needs of the whole vehicle in extreme conditions such as starting, climbing and rapid acceleration; frequent start and stop of the fuel cell system will shorten the life of the fuel cell system , affecting durability; the fuel cell system itself can only generate energy, but cannot store energy, etc. [0003] In order to learn from each other, give full play to the advantages of the fuel cell system, and make up for the shortcomings, fuel cell electric vehicles can be equipped with another energy source, and the ...
