Abstract

The invention relates to a control method and device for a fuel cell vehicle. The control method includes: calculating the average required power of the current time period; and outputting the calculated average required power of the current time period after the fuel cell is started. In the present invention, under normal operating conditions of the vehicle, the output is performed according to the calculated average demand information in the current time period. At this time, the power demand of the whole vehicle matches the output power of the fuel cell, which minimizes the charging and discharging of the energy storage components. The process improves the efficiency of the fuel cell vehicle power system, improves the adaptability of the fuel cell system to working conditions, and avoids frequent load changes and start-up and shutdown of the fuel cell.

Description

technical field [0001] The invention relates to a control method and device for a fuel cell vehicle, belonging to the technical field of fuel cell vehicles. Background technique [0002] With the continuous consumption of energy, new energy vehicles have gradually become a development trend. Among them, hydrogen fuel cell vehicles, as one of the new energy vehicles, have been highly valued by governments, major companies and research departments of various countries because of their high efficiency, low pollution, and energy security, and have broad application scenarios. [0003] However, as far as the current development status of hydrogen fuel cell vehicles is concerned, the hydrogen fuel cell system also faces various problems such as short life, high cost, poor environmental applicability, high failure rate, and complex system structure, so it needs to be done in the vehicle part. Many protection mechanisms have been developed, which restricts the promotion and applica...
