Abstract

The invention belongs to the technical field of fuel cell engines, and particularly relates to a method and a device for controlling activation of a fuel cell engine. The method for controlling the activation of the fuel cell engine comprises the following steps of: obtaining a first output voltage when the fuel cell engine works firstly at a preset power, obtaining a second output voltage when the fuel cell engine runs at the preset power when a vehicle runs, calculating an output voltage difference value according to the first output voltage and the second output voltage, and controlling thefuel cell engine to be activated when the difference value of the output voltages is larger than a first preset threshold value. The invention discloses a method for controlling activation of a fuelcell engine. The two output voltages are obtained, whether the fuel cell engine needs to be activated or not is determined by comparing the difference value of the voltages with the first preset threshold value, and therefore the fuel cell engine can be activated in time in the whole vehicle running process, and the working reliability of the fuel cell engine is improved.

Description

technical field [0001] The invention belongs to the technical field of fuel cell engines, and in particular relates to a method and device for controlling the activation of fuel cell engines. Background technique [0002] During the use of the fuel cell engine, due to the requirements of the working conditions, the actual running fuel cell engine may run in a low-to-medium power state for a long time; , the fuel cell engine may not be able to respond to high power, so that when the vehicle needs a large power in summer and winter, the fuel cell engine cannot reach the maximum power and cannot meet the needs of the vehicle. In addition, the existing technology cannot When the vehicle is running, it is determined whether the fuel cell engine needs to be activated. If the control strategy is adjusted so that the fuel cell engine is always in a high-power state, on the one hand, the efficiency of the fuel cell engine will decrease, and the user's cost will increase. On the othe...
