As the fuel storage and supply mechanism for on-board fuel cell engines, hydrogen storage and supply systems are an integral and crucial component of the development of hydrogen-powered vehicles.

[0049] Research has found that after hydrogen fuel cell vehicles are started for hydrogen refueling, if the hydrogen refueling station forgets to unplug the hydrogen refueling gun after refueling or leaves the hydrogen refueling gun and hydrogen refueling pipeline connected to the hydrogen storage equipment for a long time, and is in a pressurized state for a long time, there will be a risk of leakage and hidden dangers to hydrogen refueling safety.

[0050] Based on the above research, the present disclosure provides a vehicle hydrogenation method, device, electronic device and storage medium, which are applied to the vehicle hydrogen system controller. By obtaining the hydrogenation enable signal indicating that the hydrogenation pipeline in the hydrogenation equipment is successfully connected to the vehicle, a preset timer is started to start timing; the infrared transmitter provided in the vehicle hydrogenation system controller is controlled to start, establish a communication connection with the infrared receiver provided on the hydrogenation gun and send a hydrogenation instruction; determine whether the hydrogen storage bottle in the hydrogenation equipment is in normal working condition and the vehicle is not full of hydrogen; if so, determine whether the timing time of the timer is greater than the preset time threshold. If so, turn off the infrared transmitter; if not, control the infrared transmitter to send a pause hydrogenation instruction to the infrared receiver. This can improve the safety of vehicle hydrogenation, avoid hydrogenation components such as hydrogen pipelines and hydrogenation guns being in a pressurized state for a long time, avoid affecting the life of hydrogenation components, and reduce the possibility of leakage.

[0051] To facilitate understanding of this embodiment, a vehicle hydrogenation method disclosed in an embodiment of the present disclosure is first introduced in detail. The vehicle hydrogenation method provided in the embodiment of the present disclosure is generally executed by a computer device with certain computing capabilities. The computer device includes, for example, a terminal device or a server or other processing device. The terminal device can be a user equipment (UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (PDA), a handheld device, a computing device, an in-vehicle device, a wearable device, etc. In some possible implementations, the vehicle hydrogenation method can be implemented by a processor calling computer-readable instructions stored in a memory.

[0052] See also Figure 1 FIG. 1 is a flow chart of a vehicle hydrogen refueling method provided by an embodiment of the present disclosure, wherein the method includes steps S101 to S105, wherein:

[0053] S101: Obtain a hydrogenation enable signal indicating that the hydrogenation pipeline in the hydrogenation equipment is successfully connected to the vehicle, and start a preset timer to begin timing.

[0054] In a specific implementation, the embodiment of the present application can be applied to a vehicle hydrogen system controller in a vehicle hydrogen system. For ease of understanding of this embodiment, please refer to Figure 2 As shown in FIG, a schematic diagram of a vehicle hydrogen system provided in an embodiment of the present application is provided. Figure 2 As shown in , the vehicle hydrogen system consists of an on-board storage device and a hydrogen supply device.

[0055] Specifically, the vehicle storage device includes a vehicle hydrogen system controller, which is located at the vehicle's hydrogen refueling port. The hydrogen supply device consists of a hydrogen refueling device with a hydrogen storage bottle, a hydrogen refueling line, and a hydrogen refueling gun. The hydrogen refueling device can be connected to the vehicle's hydrogen refueling port via the hydrogen refueling line and the hydrogen refueling gun at the end of the hydrogen refueling line to provide hydrogen to the vehicle.

[0056] For further information, see Figure 3 As shown in FIG, a schematic diagram of a vehicle hydrogen system controller provided by an embodiment of the present application is shown. Figure 3 As shown in , the vehicle hydrogen system controller is provided with a timing module, a hydrogenation signal detection module, a controller drive signal detection module, a temperature signal detection module, a pressure signal detection module, a bottle valve drive module, an infrared emitter and a CPU, etc. Among them, the timing module, controller drive signal detection, hydrogenation signal detection, temperature and pressure signal detection are set in a normally powered mode. Even if the vehicle hydrogen system controller is in a closed sleep mode, real-time detection is required. When the controller drive signal or the hydrogenation enable signal is turned on, the controller is in a driving working state. Only after the hydrogen system controller is in the driving working mode will it drive the infrared emitter to send infrared signals and drive the bottle valve to open and close, etc.

[0057] In a specific implementation, when hydrogen is refueled in a vehicle using hydrogen refueling equipment, the hydrogen refueling gun is connected to the hydrogen refueling port to successfully connect the hydrogen refueling line to the vehicle. When the hydrogen refueling line is successfully connected to the vehicle, the vehicle generates a hydrogen refueling enable signal and sends the hydrogen refueling enable signal to the vehicle hydrogen system controller. When the vehicle hydrogen system controller detects the hydrogen refueling enable signal, it starts the timing module (i.e., a preset timer) to start timing.

[0058] As a possible implementation, after the vehicle hydrogen system controller starts a preset timer, the following steps 1 to 3 may be performed:

[0059] Step 1: Determine whether a short circuit or open circuit fault occurs in the pressure signal detection path for detecting the pressure signal corresponding to the hydrogen storage bottle and the temperature signal detection path for detecting the temperature signal corresponding to the hydrogen storage bottle in the vehicle hydrogen system controller.

[0060] Step 2: If it appears, then stop starting the infrared transmitter.

[0061] Step 3: If not, determine whether the vehicle hydrogen system controller receives a controller drive signal; if not, start the vehicle hydrogen system controller.

[0062] In a specific implementation, after the vehicle hydrogen system controller starts the preset timer, it is determined whether there is a short circuit or open circuit fault in the pressure signal detection path where the pressure signal detection module is located for detecting the pressure signal corresponding to the hydrogen storage bottle, and in the temperature signal detection path where the temperature signal detection module is located for detecting the temperature signal corresponding to the hydrogen storage bottle.

[0063] Specifically, if there is a short circuit or open circuit fault in any of the pressure signal detection path and the temperature signal detection path, the subsequent action of starting the infrared emitter is stopped; if there is no short circuit or open circuit fault, the controller drive signal detection module is further detected to see whether it detects the controller drive signal that controls the start of the vehicle hydrogen system controller.

[0064] Here, if the controller driving signal is not detected, the vehicle hydrogen system controller is started first. If the controller driving signal is detected, it means that the vehicle hydrogen system controller is working, and the subsequent step of starting the infrared transmitter is directly performed.

[0065] It should be noted that the pressure signal detection path and the temperature signal detection path are in a normally energized state, and even when the vehicle is stationary or not performing other work, it is still possible to detect whether there are abnormal signals based on the detected pressure and temperature.

[0066] S102 , controlling the infrared transmitter provided in the vehicle hydrogen system controller to start, establish a communication connection with the infrared receiver provided on the hydrogen filling gun, and send a hydrogen filling instruction.

[0067] In a specific implementation, the infrared transmitter in the vehicle hydrogen system controller is started, and a communication connection channel is established with the infrared receiver on the hydrogen filling gun. The infrared transmitter in the vehicle hydrogen system controller sends a hydrogen filling instruction to the infrared receiver on the hydrogen filling gun.

[0068] Here, when the infrared receiver on the hydrogen filling gun receives the hydrogen filling instruction, the bottle valve drive module set in the vehicle hydrogen system controller controls the pipeline switch corresponding to the hydrogen filling pipeline and the hydrogen filling gun switch corresponding to the hydrogen filling gun to close; the hydrogen filling pipeline is adjusted to the preset hydrogen filling pressure value, and hydrogen is filled into the vehicle from the hydrogen storage bottle through the hydrogen filling gun and the hydrogen filling pipeline.

[0069] The preset hydrogenation pressure value can be selected according to actual needs and is not specifically limited here.

[0070] S103: Determine whether the hydrogen storage bottle in the hydrogen refueling equipment is in normal working condition and whether the vehicle is not fully filled with hydrogen.

[0071] In a specific implementation, after the infrared transmitter in the vehicle hydrogen system controller sends a hydrogen refueling instruction to the infrared receiver on the hydrogen refueling gun, it determines whether the hydrogen storage bottle in the hydrogen refueling equipment has an abnormal working state or whether the current vehicle hydrogen refueling volume is full.

[0072] Here, it can be determined whether the hydrogen storage bottle in the hydrogenation equipment is in an abnormal working state based on the following steps 1 to 4:

[0073] Step 1: Collect the pressure signal corresponding to the hydrogen storage bottle through the pressure signal detection path.

[0074] Step 2: Collect the temperature signal corresponding to the hydrogen storage bottle through the temperature signal detection path.

[0075] Step 3 determines whether the pressure signal is between a preset low pressure threshold and a preset high pressure threshold, and whether the temperature signal is between a preset low temperature threshold and a preset high temperature threshold.

[0076] If yes in step 4, it is determined that the hydrogen storage bottle is in normal working condition.

[0077] In a specific implementation, if the vehicle hydrogen system controller detects through the pressure signal detection path that the pressure of the hydrogen storage bottle is lower than the preset low pressure threshold, it means that the pressure of the hydrogen storage bottle is too low at this time and is in a low pressure abnormal state; if the vehicle hydrogen system controller detects through the pressure signal detection path that the pressure of the hydrogen storage bottle is higher than the preset high pressure threshold, it means that the pressure of the hydrogen storage bottle is too high at this time and is in an overpressure abnormal state.

[0078] Furthermore, if the vehicle hydrogen system controller detects through the temperature signal detection path that the temperature of the hydrogen storage bottle is lower than the preset low temperature threshold, it means that the temperature of the hydrogen storage bottle is too low at this time and is in an abnormal state of too low bottle temperature; if the vehicle hydrogen system controller detects through the temperature signal detection path that the temperature of the hydrogen storage bottle is higher than the preset high temperature threshold, it means that the temperature of the hydrogen storage bottle is too high at this time and is in an abnormal state of over-temperature.

[0079] It should be noted that the preset low pressure threshold and the preset high pressure threshold, the preset low temperature threshold and the preset high temperature threshold can be selected according to actual needs and are not specifically limited here.

[0080] S104: If yes, determine whether the timing time of the timer is greater than a preset time threshold; if so, turn off the infrared transmitter.

[0081] In specific implementation, if the hydrogen storage bottle in the hydrogen refueling equipment is not in normal working condition and the vehicle is not fully filled with hydrogen, it is necessary to continue to determine whether the timing of the timer exceeds the preset time threshold. If the timing of the timer is greater than the preset time threshold, it means that the refueling personnel temporarily forgot to pull out the hydrogen refueling gun, and the hydrogen refueling signal was closed when the hydrogen refueling gun was connected to the vehicle's hydrogen refueling port, or the hydrogen refueling switch failed and the hydrogen refueling signal has been closed for a long time and has timed out. At this time, the infrared transmitter needs to be turned off to avoid the hydrogen refueling equipment being in a suspended and unstable standby state.

[0082] Here, after turning off the infrared transmitter, the vehicle hydrogen system controller controls the hydrogen filling gun switch corresponding to the hydrogen filling gun to be disconnected by controlling the bottle valve drive module; and controls the pipeline switch corresponding to the hydrogen filling pipeline to be disconnected by controlling the bottle valve drive module.

[0083] Optionally, after turning off the infrared transmitter, it is also possible to detect whether the vehicle hydrogen system controller has a controller drive signal. If so, the vehicle hydrogen system controller continues to perform other operations except infrared communication; otherwise, the vehicle hydrogen system controller is turned off and put into sleep mode.

[0084] It should be noted that the preset time threshold can be selected according to actual needs and is not specifically limited here. Preferably, the preset time threshold can be 60 minutes.

[0085] S105: If not, control the infrared transmitter to send a hydrogenation suspension instruction to the infrared receiver.

[0086] In specific implementation, if the hydrogen storage bottle in the hydrogen refueling equipment is not in normal working condition, or the vehicle is not fully filled with hydrogen, the vehicle hydrogen system controller controls the infrared transmitter to send a pause hydrogen refueling instruction to the infrared receiver on the hydrogen refueling gun.

[0087] Here, if a pause command is detected, the hydrogen filling gun switch is controlled to be disconnected, pausing hydrogen filling. Otherwise, after no hydrogen filling command or pause command is detected, the infrared signal from the vehicle is detected. If no infrared signal is detected within the specified time, the detection is continued to avoid misjudgment.

[0088] A vehicle hydrogenation method provided by an embodiment of the present disclosure is applied to a vehicle hydrogen system controller. By obtaining a hydrogenation enable signal indicating that the hydrogenation pipeline in the hydrogenation equipment is successfully connected to the vehicle, a preset timer is started to start timing; an infrared transmitter provided in the vehicle hydrogenation system controller is controlled to start, establish a communication connection with an infrared receiver provided on the hydrogenation gun, and send a hydrogenation instruction; determine whether the hydrogen storage bottle in the hydrogenation equipment is in normal working condition and the vehicle is not fully hydrogenated; if so, determine whether the timing time of the timer is greater than a preset time threshold. If so, turn off the infrared transmitter; if not, control the infrared transmitter to send a hydrogenation pause instruction to the infrared receiver. This can improve the safety of vehicle hydrogenation, avoid hydrogenation components such as hydrogen pipelines and hydrogenation guns being in a pressurized state for a long time, avoid affecting the life of hydrogenation components, and reduce the possibility of leakage.

[0089] Those skilled in the art will understand that in the above-mentioned method of the specific implementation method, the writing order of each step does not mean a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.

[0090] Based on the same inventive concept, a vehicle hydrogenation device corresponding to the vehicle hydrogenation method is also provided in the embodiment of the present disclosure.

[0092] The enabling timing module 410 is used to obtain a hydrogenation enabling signal indicating that the hydrogenation pipeline in the hydrogenation equipment is successfully connected to the vehicle, and start a preset timer to start timing.

[0093] The infrared communication module 420 is used to control the infrared transmitter provided in the vehicle hydrogen system controller to start, establish a communication connection with the infrared receiver provided on the hydrogen filling gun and send a hydrogen filling instruction.

[0094] The hydrogen storage bottle status detection module 430 is used to determine whether the hydrogen storage bottle in the hydrogen refueling equipment is in a normal working state and the vehicle is not fully refueled with hydrogen.

[0095] The first hydrogenation control module 440 is configured to determine whether the timing time of the timer is greater than a preset time threshold, and if so, turn off the infrared emitter.

[0096] The second hydrogenation control module 450 is configured to control the infrared transmitter to send a hydrogenation suspension instruction to the infrared receiver if no.

[0098] A vehicle hydrogenation device provided by an embodiment of the present disclosure is applied to a vehicle hydrogen system controller.

If so, the infrared transmitter is turned off; if not, the infrared transmitter is controlled to send a hydrogenation pause instruction to the infrared receiver. This can improve the safety of vehicle hydrogenation, avoid hydrogenation components such as hydrogen pipelines and hydrogenation guns being in a pressurized state for a long time, avoid affecting the life of hydrogenation components, and reduce the possibility of leakage.
