Description

Technical Field

[0001] The present application relates to the technical field of fuel cell hybrid commercial vehicles, and in particular to a method, device, medium and equipment for predicting the driving range of fuel cell commercial vehicles. Background Art

[0002] Fuel cell vehicles have attracted widespread attention as an environmentally friendly and efficient new energy vehicle. Fuel cell vehicles use hydrogen as the main fuel and directly convert chemical energy into electrical energy through fuel cells. They have the advantages of high efficiency, cleanliness, and long driving range. Accurate evaluation of the energy consumption and driving range of fuel cell vehicles has always been a technical problem in the industry. The traditional method of evaluating energy consumption and driving range is to test the vehicle on a chassis dynamometer from full hydrogen and full charge to parking. Filling up with hydrogen is a time-consuming and difficult process. The industry standard for filling up the vehicle to be tested is that the pressure reaches the rated pressure when the internal temperature of the on-board hydrogen bottle is 15°C. However, filling the on-board hydrogen bottle with hydrogen is a heating process, and the internal temperature of the on-board hydrogen bottle will rise rapidly. Although it is added to the rated pressure of the on-board hydrogen bottle, because the internal temperature is higher than 15°C, when the internal temperature of the on-board hydrogen bottle drops to 15°C, the internal pressure of the hydrogen bottle will also drop accordingly, resulting in insufficient hydrogen quality actually stored in the hydrogen bottle. The general practice is to pressurize, wait for the temperature to drop, and then continue to pressurize, and repeat this process. However, the heat dissipation capacity of the on-board hydrogen bottle is currently poor, and it takes a long time to wait for the internal temperature of the on-board hydrogen bottle to drop to room temperature. Therefore, the process of filling up with hydrogen is a very time-consuming and laborious process. In addition, long-term real vehicle testing is required, and the testing process is cumbersome, time-consuming, and costly.

[0003] Therefore, a method is needed to quickly and accurately test the driving range of fuel cell vehicles. Summary of the invention

Specifically, this application fixes the target commercial vehicle on the chassis dynamometer, sets the sliding resistance coefficient of the vehicle to be tested, and adjusts the SOC state of the energy storage battery to meet the pure electric mode test requirements. This application selects the corresponding cycle conditions, runs 3 complete cycle conditions in pure electric mode, and obtains the first power consumption based on the average of the 3 operation results. Among them, the calculation formula for the first power consumption is as follows: ; in, The first power consumption is is the output current of the energy storage battery, is the output voltage of the energy storage battery, and T is the time for the target commercial vehicle to operate in the pure electric mode.
