Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of hydrogen refueling, and particularly relates to a hydrogen refueling control method and device, a storage medium and computer equipment. BACKGROUND

[0002] The refueling capacity and energy consumption of a hydrogen refueling station are greatly affected by the refueling rate. The greater the refueling rate, the stronger the refueling capacity of the hydrogen refueling station. However, due to the material performance limitation of the on-board hydrogen storage cylinder, the hydrogen temperature in the on-board hydrogen storage system during the refueling process cannot exceed 85 DEG C. Therefore, different refueling rates need to be used under different ambient temperatures, that is, the higher the ambient temperature and the initial temperature of the on-board hydrogen storage system, the lower the refueling rate.

[0003] At present, the vehicle needs to send the initial temperature of the on-board hydrogen storage system to the hydrogen refueling station through a communication tool between the vehicle and the hydrogen refueling station. However, in practice, the same vehicle will be refueled at different types of hydrogen refueling stations, and the same hydrogen refueling station will provide refueling services to different types of vehicles, and different types of vehicles or hydrogen refueling stations often have different communication standards, so that the communication between the vehicle and the hydrogen refueling station is difficult to achieve.

[0004] However, the initial temperature in the on-board hydrogen storage cylinder may be in a hot soak or cold soak state due to the effect of environmental conditions. For example, the on-board hydrogen storage cylinder is directly irradiated by the sun for a long time, which will cause the initial temperature in the cylinder to be higher than the ambient temperature (hot soak). In this case, the hydrogen refueling station control system cannot obtain the real hydrogen temperature in the on-board hydrogen storage cylinder under the condition of no communication. Therefore, in order to ensure the safety of refueling, the refueling rate needs to be determined according to the hot soak temperature of the on-board hydrogen storage cylinder, that is, the hydrogen refueling station process control module selects the refueling rate (the same ambient temperature corresponds to a fixed hot soak temperature) according to the hot soak temperature obtained by adding the heat soak allowance to the ambient temperature measured by the temperature sensor. This will result in a low refueling rate of the on-board hydrogen storage cylinder under no hot soak condition.

[0005] Therefore, there is an urgent need for a hydrogen refueling control method and device, a storage medium and computer equipment. SUMMARY

[0042] To solve the above technical problems in the prior art, the present application provides a hydrogenation control method, wherein, in the present embodiment, the state of the vehicle-mounted hydrogen storage cylinder includes a hot soaking state and a non-hot soaking state.

[0050] In the embodiment, the hydrogen temperature in the vehicle-mounted hydrogen storage device is controlled below 85 DEG C in the hydrogen filling process according to the requirements of international standards. In order to meet the requirements of international standards, the hydrogen temperature in the hydrogen filling process needs to be in a preset safety range. In this way, the temperature rise of the vehicle-mounted hydrogen storage device in the hydrogen filling process is controlled to prevent the hydrogen from exploding due to the rapid temperature rise.

[0051] In the embodiment, the hydrogen filling rate is calculated by a pre-trained hydrogen filling rate calculation model.

[0058] The hydrogen to be filled is cooled according to the cooling temperature of the hydrogen to be filled to fill the cooled hydrogen into the vehicle-mounted hydrogen storage cylinder.

[0059] Example Two

[0060] To solve the above technical problems in the prior art, the embodiment of the present application provides a hydrogenation control method based on the first embodiment, wherein in the present embodiment, the weather information includes weather conditions, sunshine intensity, temperature, humidity, wind power and wind direction, and the environmental state includes an initial state, a hot soaking state and a cold soaking state.

[0065] S232, when the hydrogen storage cylinder is in the cold soaking state, the initial temperature in the vehicle-mounted hydrogen storage cylinder is the difference between the environmental temperature and a second preset fixed temperature;

[0066] S233, when the hydrogen storage cylinder is in the initial state, the initial temperature in the vehicle-mounted hydrogen storage cylinder is the environmental temperature;

[0067] S24, calculation of the hydrogenation rate according to the initial temperature in the vehicle-mounted hydrogen storage cylinder, the pre-acquired initial pressure in the vehicle-mounted hydrogen storage cylinder and the volume of the vehicle-mounted hydrogen storage cylinder, and filling of hydrogen into the vehicle-mounted hydrogen storage cylinder at the hydrogenation rate.

[0068] In the present embodiment, the method further comprises:

[0069] When the hydrogen storage cylinder is in the hot soaking state, the hot soaking state is graded according to the numerical values of the weather conditions, sunshine intensity, temperature, humidity, wind power and wind direction, so as to determine the first preset fixed temperature according to the grade of the hot soaking state;

[0070] When the hydrogen storage cylinder is in the cold soaking state, the cold soaking state is graded according to the numerical values of the weather conditions, sunshine intensity, temperature, humidity, wind power and wind direction, so as to determine the second preset fixed temperature according to the grade of the cold soaking state.

[0071] In the present embodiment, before the filling of hydrogen into the vehicle-mounted hydrogen storage cylinder at the hydrogenation rate in step S24, the method further comprises:

[0072] determination of the to-be-filled hydrogen cooling temperature according to the initial temperature in the vehicle-mounted hydrogen storage cylinder;

[0073] The hydrogen to be filled is cooled according to a cooling temperature of the hydrogen to be filled, so as to fill the cooled hydrogen into the vehicle-mounted hydrogen storage cylinder.

[0074] With reference to Figure 3 The embodiment is applied to a hydrogen filling control method of a vehicle, and comprises the following steps:

[0075] The vehicle is filled with hydrogen;

[0076] Hydrogen filling preparation: obtaining weather information, ambient temperature, initial pressure in the vehicle-mounted hydrogen storage cylinder and volume of the vehicle-mounted hydrogen storage cylinder;

[0077] The hydrogen filling rate is calculated according to the initial temperature in the vehicle-mounted hydrogen storage cylinder, the initial pressure in the vehicle-mounted hydrogen storage cylinder and the volume of the vehicle-mounted hydrogen storage cylinder, wherein the initial temperature in the vehicle-mounted hydrogen storage cylinder is determined by the weather information and the ambient temperature;

[0078] The filling is performed according to the hydrogen filling rate.

[0079] In the embodiment, on the one hand, in a high-temperature environment, the weather is cloudy, the ambient temperature is 35℃, for a hydrogen flow vehicle with a hydrogen storage capacity of 10kg, the hydrogen is not pre-cooled, and the initial pressure in the vehicle-mounted hydrogen storage cylinder is 6Mpa. The hydrogen filling rate of the present application is compared with that of the prior art as follows:

[0080] According to the hydrogen storage capacity of 10kg and the hydrogen density of 40g / L, the volume of the vehicle-mounted hydrogen storage cylinder is calculated to be 25L;

[0081] In the present application, the weather is cloudy, and therefore the initial temperature in the vehicle-mounted hydrogen storage cylinder is the ambient temperature, i.e. 35℃. The ambient temperature of 35℃, the volume of the vehicle-mounted hydrogen storage cylinder of 25L and the initial pressure in the vehicle-mounted hydrogen storage cylinder of 6Mpa are used to fill the vehicle-mounted hydrogen storage cylinder. Based on the pre-trained hydrogen filling rate calculation model, the hydrogen filling rate is 0.21MPa / s, and the shortest time required is 6.5min;

[0082] In the prior art, the weather is cloudy, and therefore the initial temperature in the vehicle-mounted hydrogen storage cylinder is the heat soaking temperature, i.e. the sum of the ambient temperature of 35℃ and the preset temperature of 15℃, i.e. 50℃. The heat soaking temperature of 50℃, the volume of the vehicle-mounted hydrogen storage cylinder of 25L and the initial pressure in the vehicle-mounted hydrogen storage cylinder of 6Mpa are used to fill the vehicle-mounted hydrogen storage cylinder. Based on the pre-trained hydrogen filling rate calculation model, the hydrogen filling rate is 0.13MPa / s, and the shortest time required is 10.5min.

[0083] Therefore, the maximum filling rate of the hydrogen filling control method of the present application is increased by about 50% compared with that of the prior art.

[0084] On the other hand, in a high-temperature environment, the weather is cloudy, the ambient temperature is 35℃, for a hydrogen stream vehicle with a hydrogen storage capacity of 10kg, the hydrogen is not pre-cooled, the initial pressure in the vehicle-mounted hydrogen storage cylinder is 6Mpa, and the pre-cooled hydrogen temperature of the present application and the prior art is as follows:

[0085] In the present application, the weather is cloudy, and therefore the initial temperature in the vehicle-mounted hydrogen storage cylinder is the ambient temperature, that is, 35℃. Based on the corresponding relationship between the initial temperature in the vehicle-mounted hydrogen storage cylinder and the pre-cooled hydrogen temperature, the pre-cooled hydrogen temperature is obtained as 35℃ according to the initial temperature of 35℃ in the vehicle-mounted hydrogen storage cylinder.

[0086] In the prior art, the weather is cloudy, and therefore the initial temperature in the vehicle-mounted hydrogen storage cylinder is the heat soaking temperature, that is, the sum of the ambient temperature 35℃ and the preset temperature 15℃, that is, 50℃. Based on the corresponding relationship between the initial temperature in the vehicle-mounted hydrogen storage cylinder and the pre-cooled hydrogen temperature, the pre-cooled hydrogen temperature is obtained as 30℃ according to the initial temperature of 50℃ in the vehicle-mounted hydrogen storage cylinder.

[0087] Therefore, under a higher ambient temperature, in order to improve the filling rate of the hydrogen refueling station, the higher the initial temperature in the vehicle-mounted hydrogen storage cylinder, the lower the pre-cooled hydrogen temperature required, thereby increasing the energy consumption of the hydrogen refrigeration machine and other equipment in the hydrogen refueling station.

[0088] The hydrogen refueling control method of the present embodiment identifies the weather conditions, mainly including sunny days and cloudy days, rainy days, etc., and adopts a more targeted operation strategy in terms of filling according to the obtained weather information, thereby optimizing energy consumption and filling capacity.

[0089] The hydrogen refueling control method of the present embodiment adds a weather identification step, determines the initial temperature in the vehicle-mounted hydrogen storage cylinder according to the provided weather conditions, considers that the initial temperature in the vehicle-mounted hydrogen storage cylinder is equal to the heat soaking temperature when it is sunny and the sunlight is sufficient, and considers that the initial temperature in the vehicle-mounted hydrogen storage cylinder is equal to the ambient temperature when it is cloudy or rainy and there is no direct sunlight, so that a more accurate filling rate can be obtained through the initial temperature in the vehicle-mounted hydrogen storage cylinder which is closer to the actual environmental conditions.
