Embodiment 1

[0037] Embodiment 1: A fuel cell engineering vehicle energy control method based on driving conditions, such as figure 2 As shown, its fuel cell engineering vehicle includes vehicle control system 1, motor drive system 2, bodywork fog cannon system 3, lithium battery system 4 and hydrogen fuel cell system 5, vehicle control system 1 is connected with motor drive system 2, bodywork The fog cannon system 3, the lithium battery system 4 and the hydrogen fuel cell system 5 are electrically connected, the output end of the hydrogen fuel cell system 5 is electrically connected to the input end of the lithium battery system 4, and the output end of the lithium battery system 4 is respectively connected to the motor drive The system 2 is electrically connected to the bodywork fog cannon system 3; the vehicle control system 1 monitors the current working status of the bodywork fog cannon system 3 and the motor drive system 2 respectively, and selectively turns on the hydrogen fuel cell...

Embodiment 2

[0055] Embodiment 2: The difference between this embodiment and Embodiment 1 is that this embodiment divides the power of the lithium battery system 4 from the minimum value to the maximum value into six adjacent power intervals according to the requirements; that is, in Confirming the SOC of the remaining power of the lithium battery system 4 in step S5 is to divide the power of the lithium battery system 4 into six adjacent power ranges from the minimum value to the maximum value. Two power thresholds are set between the maximum values, the first power threshold is located at the endpoints of the two adjacent minimum power intervals of the lithium battery system 4, and the first power threshold is 40% of the maximum power of the lithium battery system 4; the second power threshold is set In order that the lithium battery system 4 can independently drive the power of the motor drive system 2 and the top-mounted fog cannon system 3, the second power threshold is selected to be ...

Abstract

The invention provides a fuel cell engineering vehicle energy control method based on driving conditions, and the fuel cell engineering vehicle comprises a whole vehicle control system, a motor driving system, an upper fog gun system, a lithium battery system and a hydrogen fuel cell system. The whole vehicle control system observes the current working states of the upper fog gun system, the motor driving system and the motor driving system, and whether the hydrogen fuel cell system is allowed to be started or not is judged in advance; aiming at the situation that the fuel cell engineering vehicle runs under different working conditions, the trend of power change required by the fog gun system and the motor driving system installed on the fuel cell engineering vehicle is pre-judged, timely response of power of the hydrogen fuel cell system and a lithium battery system of the fuel cell engineering vehicle is controlled in advance, and the situation that energy cannot be supplemented in time is avoided, and the endurance and the output capability of the fuel cell engineering vehicle are influenced.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle control, in particular to an energy control method for a fuel cell engineering vehicle based on driving conditions. Background technique [0002] Automobile is a commonly used means of transportation, and its use in transportation and travel has been widely accepted. Traditional automobiles use automobile engines as power sources and use fossil fuels. The exhaust gas generated by the combustion of fossil fuels has caused huge damage to human health and the ecological environment. harm. As the world's growing energy demand continues to expand, and environmental issues are getting more and more attention, new energy vehicles, as a way of using clean energy, have developed rapidly. Among them, the fuel cell engineering vehicle has the advantages of high efficiency, zero pollution, low noise, and fast start-up. Its hydrogen fuel cell is one of the main development directions for the next g...
