[0002] A fuel cell engine is a device that converts the chemical energy of fuel into electrical energy based on a redox reaction. Its fuels are primarily hydrogen and oxygen. The hydrogen mainly comes from high-pressure cylinders containing purified hydrogen. The oxygen primarily comes from the air.
[0003] A fuel cell engine contains multiple pipelines and structural cavities, which originate from the water, air, and hydrogen circuits within the engine. These pipelines and cavities are used to transport hydrogen, water, and other gases. During operation, static electricity can accumulate on the surfaces of some pipelines and cavities due to high-speed gas flow and friction. When this static electricity accumulates to a certain level, it can damage or even puncture other electronic components within the fuel cell engine. Furthermore, in the event of a hydrogen leak, hydrogen combustion or even an explosion may occur.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0058] Considering that excessive static electricity accumulation on a fuel cell engine can easily damage or even break down other electronic components within the engine, and that excessive static electricity accumulation during a hydrogen leak could potentially lead to hydrogen combustion or even an explosion, this application provides a method, apparatus, electronic device, and medium for eliminating static electricity in a fuel cell engine. This eliminates accumulated static electricity on the fuel cell engine, thereby preventing damage or breakdown of other electronic components, or the occurrence of hydrogen combustion or explosion. The following embodiments illustrate this approach.
[0059] Example 1:
[0060] To facilitate understanding of this embodiment, a detailed description of a static electricity elimination method for a fuel cell engine disclosed in this application embodiment will be provided first. The fuel cell engine includes multiple target components, which are components that generate static electricity during the operation of the fuel cell engine. The fuel cell engine is divided into multiple coverage areas. For each coverage area, the same conductive mesh is attached to the outer surface of the target component located in that coverage area. For each conductive mesh, one end of an electrostatic detector and one end of a switch are connected to each other. The other end of the switch is connected to one end of a resistor corresponding to the switch, and the other end of the resistor is grounded. Different conductive meshes are connected to different electrostatic detectors and switches. Figure 1 A flowchart illustrating a method for eliminating static electricity in a fuel cell engine according to an embodiment of this application is shown, as follows: Figure 1 As shown, it includes the following steps:
[0061] S101: Receive the voltage value accumulated on the conductive wire connected to each electrostatic detector, and determine whether the voltage value accumulated on each conductive wire is greater than the first preset threshold.
[0062] S102: When the voltage value accumulated on the target conductive network is greater than the first preset threshold, the insulation value of the fuel cell engine is detected. If the insulation value is greater than the second preset threshold, the switch connected to the target conductive network is closed to release the static electricity accumulated on the target conductive network.
[0063] In this embodiment, the fuel cell engine includes multiple pipelines and structural cavities. These pipelines and cavities originate from the water, air, and hydrogen circuits within the fuel cell engine, respectively, and are used to transport hydrogen, air, and water. During operation, due to high-speed airflow and air friction, static electricity may accumulate on the surfaces of some pipelines and structural cavities. The target components in this embodiment refer to the pipelines and structural cavities within the fuel cell engine that generate static electricity.
[0064] In this embodiment, the fuel cell engine is pre-divided into multiple coverage areas. The number of coverage areas is determined by the size of the fuel cell engine; specifically, the size of the fuel cell engine is positively correlated with the number of coverage areas. A larger fuel cell engine requires more coverage areas, and vice versa. There is no overlap between any two coverage areas, and all coverage areas completely cover a designated side of the fuel cell engine. When the fuel cell engine resembles a cuboid device, the designated side can be the side with the largest area of the fuel cell engine.
[0065] Each coverage area typically contains at least one target component, and for each coverage area, the same conductive mesh is attached to the outer surface of the target component located in that coverage area.
[0066] In this embodiment, the conductive mesh is specifically a conductive metal mesh, which can be a woven mesh with horizontal and vertical interlacing, or a mesh formed by spirally winding conductive metal wires around the target component.
[0067] In one possible implementation, when the conductive mesh is a woven mesh with interlaced horizontal and vertical strands, each conductive mesh is either a complete conductive mesh or a conductive mesh composed of at least two sub-mesh panels. When the conductive mesh is composed of at least two sub-mesh panels, the contact area between two adjacent sub-mesh panels is not less than a preset area. Specifically, each sub-mesh is a conductive sub-mesh, which is a woven mesh with interlaced horizontal and vertical strands.
[0068] In this embodiment, by ensuring that the contact area between two adjacent subnets is not less than a preset area, it is beneficial to ensure that static electricity in the same coverage area is released.
[0069] Figure 2 This illustration shows a schematic diagram of the connection relationships between the conductive grid, electrostatic discharge detector, switch, resistor, fuel cell controller, and insulation detector provided in an embodiment of this application. Figure 2 As shown, when there are 4 coverage areas (e.g.) Figure 2 When considering regions one, two, three, and four, the system comprises a total of four conductive meshes, four resistors, four switches, and four electrostatic detectors. For example... Figure 2 As shown, for each conductive mesh, the conductive mesh is connected to one end of an electrostatic detector and a switch, the other end of the switch is connected to one end of the resistor corresponding to the switch, and the other end of the resistor is grounded; different conductive meshes are connected to different electrostatic detectors and switches.
[0070] Specifically, for each conductive mesh, when the conductive mesh is connected to one end of an electrostatic detector and one end of a switch, the electrostatic detector can be connected to any point on the conductive mesh, and the switch can be connected to any point on the conductive mesh.
[0071] In one possible implementation, such as Figure 2 As shown, for each switch, the communication terminal of the switch is communicatively connected to the fuel cell controller; for each electrostatic discharge (ESD) detector, the ESD detector is communicatively connected to the fuel cell controller; the fuel cell controller is also communicatively connected to an insulation detector; this method is applied to the fuel cell controller. The communication connection can be wireless communication via a wireless signal or wired communication via a network cable.
[0072] In step S101, the fuel cell controller receives in real time the voltage value of accumulated static electricity on the conductive network connected to each electrostatic detector. For each voltage value detected by the electrostatic detector, the fuel cell controller determines whether the accumulated voltage value on each conductive network is greater than a first preset threshold. When the accumulated voltage value on the conductive network is greater than the first preset threshold, it indicates that there is a large amount of accumulated static electricity on the conductive network, which needs to be eliminated (static discharge). When the accumulated voltage value on the conductive network is not greater than (less than or equal to) the first preset threshold, it indicates that there is a small amount of accumulated static electricity on the conductive network, which does not need to be eliminated (static discharge).
[0073] It should be noted that the static electricity accumulated on the conductive wire is actually generated by the target component to which it is attached.
[0074] In step S102, the target conductive network is a conductive network whose accumulated voltage value is greater than a first preset threshold, that is, a conductive network that needs to be electrostatic discharge. When the target conductive network exists, the insulation value of the fuel cell engine is detected. If the insulation value is greater than a second preset threshold, the switch connected to the target conductive network is controlled to close. After the switch is closed, the static electricity accumulated on the target component is released to ground through the conductive network, the switch, and the resistor, thereby eliminating the static electricity accumulated on the target component, that is, releasing the static electricity accumulated on the target conductive network.
[0075] In this embodiment, considering that if the insulation value of the fuel cell engine is too low, it could easily lead to the risk of electric shock, it is necessary to ensure that the insulation value of the fuel cell engine is greater than a second preset threshold before electrostatic discharge is performed to avoid the risk of electric shock. If the switch is closed for electrostatic discharge when the insulation value is not greater than the second preset threshold, the insulation value of the fuel cell engine will continue to decrease. Therefore, in this embodiment, when the insulation value of the fuel cell engine is not greater than the second preset threshold, the switch connected to the target conductive network is opened to prevent the insulation value of the fuel cell engine from decreasing further.
[0076] In one possible implementation, when the accumulated voltage value on at least two target conductive wires exceeds a first preset threshold, simultaneously grounding these target conductive wires for electrostatic discharge could easily cause the insulation value of the fuel cell engine to decrease more rapidly, thereby posing a risk of electric shock to personnel. Therefore, to avoid the above problem, in this embodiment, step S102 can be performed according to the following steps:
[0077] S1021: When the accumulated voltage value on at least two target conductive wires is greater than the first preset threshold, the electrostatic discharge cycle of each target conductive wire is determined in descending order of voltage value.
[0078] S1022: Detect the insulation value of the current fuel cell engine for the target conductive network in the current electrostatic discharge cycle;
[0079] If the insulation value is greater than the second preset threshold, the switch connected to the target conductive network is closed to release the static electricity accumulated on the target conductive network.
[0080] If the insulation value is not greater than the second preset threshold, the switch connected to the target conductive network is disconnected, and the insulation value of the fuel cell engine is detected in real time. When the insulation value of the fuel cell engine is greater than the second preset threshold, the switch connected to the target conductive network is closed to release the static electricity accumulated on the target conductive network.
[0081] In step S1021, if there are three target conductive meshes, namely target conductive mesh A, B and C, and the corresponding voltage values of these three target conductive meshes are 90V, 50V and 70V respectively, then according to the order of voltage value from large to small, the electrostatic discharge rounds of each target conductive mesh are as follows: the first round is to perform electrostatic discharge on target conductive mesh A, the second round is to perform electrostatic discharge on target conductive mesh C, and the third round is to perform electrostatic discharge on target conductive mesh B.
[0082] In step S1022, the insulation value of the fuel cell engine is detected for the target conductive network A in the first round of electrostatic discharge. If the current insulation value is greater than a second preset threshold, the switch connected to the target conductive network A is closed to release the static electricity accumulated on the target conductive network A; in other words, the static electricity accumulated on the target component attached to the target conductive network A is released. If the current insulation value is not greater than the second preset threshold, continuing to release static electricity from the target conductive network A would result in an even lower insulation value, increasing the risk of electric shock. Therefore, when the current insulation value is not greater than the second preset threshold, the switch connected to the target conductive network A is opened, and the insulation value of the fuel cell engine is monitored in real time during the waiting period. When the insulation value of the fuel cell engine rises to a level greater than the second preset threshold, the switch connected to the target conductive network A is closed, and the static electricity accumulated on the target conductive network A is released again.
[0083] Next, after the electrostatic discharge accumulated on target conductive network A is completed, the insulation value of the fuel cell engine is detected for the second round of electrostatic discharge on target conductive network C. If the current insulation value is greater than a second preset threshold, the switch connected to target conductive network C is closed, thereby releasing the electrostatic discharge accumulated on target conductive network C. In other words, the electrostatic discharge accumulated on the target component attached to target conductive network C is released. If the current insulation value is not greater than the second preset threshold, continuing to discharge electrostatic discharge on target conductive network C would lead to an even lower insulation value, thus increasing the risk of electric shock. Therefore, when the current insulation value is not greater than the second preset threshold, the switch connected to target conductive network C is opened, and the insulation value of the fuel cell engine is monitored in real time during the waiting period. When the insulation value of the fuel cell engine rises to greater than the second preset threshold, the switch connected to target conductive network C is closed, and the electrostatic discharge accumulated on target conductive network C is released again.
[0084] Similarly, after the static electricity accumulated on the target conductive network C is discharged, the insulation value of the fuel cell engine is detected for the target conductive network B in the third round of static electricity discharge. If the current insulation value is greater than the second preset threshold, the switch connected to the target conductive network B is closed, thereby releasing the static electricity accumulated on the target conductive network B. In other words, the static electricity accumulated on the target component attached to the target conductive network B is released. If the current insulation value is not greater than the second preset threshold, continuing to discharge static electricity on the target conductive network B would lead to an even lower insulation value, thus increasing the risk of electric shock. Therefore, when the current insulation value is not greater than the second preset threshold, the switch connected to the target conductive network B is opened, and the insulation value of the fuel cell engine is monitored in real time during the waiting process. When the insulation value of the fuel cell engine rises to greater than the second preset threshold, the switch connected to the target conductive network B is closed, and the static electricity accumulated on the target conductive network B is released again.
[0085] In one possible implementation, when the accumulated voltage value on the target conductive network exceeds a first preset threshold, step S102 can be executed according to the following steps:
[0086] When the accumulated voltage value on a target conductive network exceeds a first preset threshold, the insulation value of the fuel cell engine is detected.
[0087] If the insulation value is greater than the second preset threshold, the switch connected to the target conductive network is closed to release the static electricity accumulated on the target conductive network.
[0088] If the insulation value is not greater than the second preset threshold, the switch connected to the target conductive network is disconnected.
[0089] In one possible implementation, such as Figure 2As shown, the fuel cell controller is also communicatively connected to an insulation detector. When the fuel cell controller performs step S102 to detect the insulation value of the fuel cell engine, it can specifically perform the following steps:
[0090] It receives the insulation value of the fuel cell engine detected by the insulation detector in real time;
[0091] or,
[0092] Send an insulation test command to the insulation tester to receive the insulation value of the fuel cell engine returned by the insulation tester.
[0093] In this embodiment, the insulation detector can detect the insulation value of the fuel cell engine in real time and send the detected insulation value to the fuel cell controller. Alternatively, when the insulation value of the fuel cell engine needs to be obtained, an insulation detection command can be sent to the insulation detector to receive the insulation value of the fuel cell engine returned by the insulation detector.
[0094] In one possible implementation, after performing step S102 to release the static electricity accumulated on the target conductive network, the following steps may also be performed:
[0095] S1031: For a target conductive network undergoing electrostatic discharge, receive the current voltage value on the target conductive network detected by an electrostatic detector connected to the target conductive network;
[0096] S1032: If the current voltage value on the target conductive network is less than the third preset threshold, the switch connected to the target conductive network is disconnected to stop releasing static electricity on the target conductive network; the third preset threshold is less than the first preset threshold.
[0097] In step S1031, during the process of releasing the static electricity accumulated on the target conductive network, the current voltage value of the target conductive network, detected by an electrostatic detector connected to the target conductive network, is received in real time. During the process of releasing the static electricity accumulated on the target conductive network, the received voltage value should gradually decrease.
[0098] In step S1032, after the static electricity accumulated on the target conductive network is released, if the voltage value of the remaining static electricity on the target conductive network is less than a third preset threshold, the switch connected to the target conductive network is disconnected to stop releasing the static electricity on the target conductive network.

[0100] Based on the same technical concept, this application also provides an electrostatic elimination device for a fuel cell engine. The fuel cell engine includes multiple target components, which are components that generate static electricity during the operation of the fuel cell engine. The fuel cell engine is divided into multiple coverage areas. For each coverage area, the same conductive mesh is attached to the outer surface of the target component in that coverage area. For each conductive mesh, the conductive mesh is connected to one end of an electrostatic detector and a switch. The other end of the switch is connected to one end of a resistor corresponding to the switch, and the other end of the resistor is grounded. Different conductive meshes are connected to different electrostatic detectors and switches. Figure 3 A schematic diagram of the structure of an electrostatic eliminator for a fuel cell engine provided in an embodiment of this application is shown, as follows: Figure 3 As shown, it includes:
[0101] The first receiving module 301 is used to receive the voltage value accumulated on the conductive wire connected to each of the electrostatic detectors, so as to determine whether the voltage value accumulated on each of the conductive wires is greater than a first preset threshold.
