Abstract

The embodiments of the invention disclose a vehicle energy control method and device of a vehicle, the vehicle and a storage medium. The vehicle energy control method comprises the steps: the surpluselectric quantity of a power cell at the current moment is obtained, and according to the surplus electric quantity and the surplus electric quantity threshold, a first output power standby value of afuel cell engine is determined; based on a heat management power threshold value, the unit time output power and the minimum output power of the fuel cell engine, a second output power standby valueof the fuel cell engine is determined; according to the vehicle required power, the maximum discharge power of the power cell, the first output power standby value and the second output power standbyvalue, the target output power of the fuel cell engine at the current moment is determined; and based on the working state of the power cell, the vehicle required power, the target output power and the maximum working power of the power cell at the current moment, the target working power of the power cell at the current moment is determined. The vehicle energy utilization rate is increased, and the vehicle energy consumption rate is decreased.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of electric vehicle power, and in particular, to a vehicle energy control method, device, vehicle, and storage medium of a vehicle. Background technique [0002] Fuel Cell Electric Vehicle (FCEV) has the advantages of zero emission and high efficiency. However, if the fuel cell system is installed alone, there are some shortcomings, such as slow dynamic power response, and cannot meet the needs of the entire vehicle under 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, and cannot store energy. [0003] In order to learn from each other's strengths, make full use of the advantages of fuel cell systems, and make up for shortcomings, fuel cell electric vehicles can be equipped with another energy sour...
