[0032] Controlling sleep mode: The device is in a low-power state and does not output drive functions, so as not to cause battery depletion.

[0033] like Figure 1 As shown, this embodiment discloses a fuel cell control system, including: a fuel cell controller, a fuel cell system, and a data acquisition controller;

[0034] The fuel cell controller is electrically connected to the fuel cell system, and the data acquisition controller is electrically connected to the fuel cell controller.

[0036] The first enabling circuit, the level driving circuit, and the first communication circuit are all electrically connected to the first control circuit.

[0037] Optionally, the fuel cell controller includes a second enabling activation circuit, a load drive circuit, a second communication circuit, and a second control circuit, wherein the second enabling activation circuit, the load drive circuit, and the second communication circuit are all electrically connected to the second control circuit.

[0038] Optionally, the fuel cell system includes a hydrogen circuit, an air circuit, and a water circuit, all of which are electrically connected to a load drive circuit.

[0039] Optionally, the second enabling activation circuit is electrically connected to the key switch.

[0040] Optionally, the fuel cell control system is electrically connected to the battery, and the battery provides power to the fuel cell control system.

[0041] Optionally, the first enabling circuit is communicatively connected to the user terminal.

[0042] Optional, such as Figure 2 As shown, the fuel cell controller also includes a 6.25V voltage circuit, a 5V voltage circuit, transistor T1, and transistor T2;

[0043] The input terminal of the second control circuit is connected in series with diodes D1 and D2, with the cathodes of diodes D1 and D2 connected together. The output terminal of the second control circuit is connected to the input terminal of a 6.25V voltage circuit, and the output terminal of the 6.25V voltage circuit is connected to the anode of diode D3. The output terminal of the load drive circuit is connected to the base of transistor T1, the collector of transistor T1 is connected to the input terminal of a 5V voltage circuit, the emitter of transistor T1 is connected to the output terminal of the 5V voltage circuit, the gate of transistor T2 is connected to the output terminal of the load drive circuit, the source of transistor T2 is connected to the output terminal of the 5V voltage circuit, and the drain of transistor T2 is connected to an external device.

[0044] Optionally, the anode of the diode D1 is connected to the power indicator light BATT1.

[0045] Optionally, a power indicator light BATT2 is connected between the cathode of the diode D1 and the input terminal of the 6.25V voltage circuit.

[0046] Optionally, the anode of the diode D2 is connected to the relay.

[0047] Optionally, the user terminal sends information to the first control circuit, and the first control circuit outputs a high-level signal through the level drive circuit to wake up the fuel cell controller. The load drive circuit of the fuel cell controller drives the fuel cell system to start.

[0048] When the fuel cell controller is woken up, the user sends an update program to the data acquisition controller, and the data acquisition controller sends the update program to the fuel cell controller to update the program of the fuel cell controller.

[0049] After the operation is completed, a sleep signal is sent to the data acquisition controller through the user terminal. The data acquisition controller is in sleep mode and does not output an activation command to the fuel cell controller. At this time, the fuel cell controller is in sleep mode.

[0050] When the fuel cell system needs to activate and wake up the fuel cell controller to start functions such as winter purging, or when the fuel cell controller program has a problem and needs to be updated, it can activate and wake up the fuel cell controller at any time (unaffected by whether the vehicle is started on site) and anytime (unaffected by distance) to complete the functions required by the system, such as winter parking purging, or update the fuel cell controller program. This facilitates real-time program updates, early detection of problems, and prevention of malfunctions.

[0051] The specific working principle is as follows:

[0052] In specific examples, the user end is a cloud platform APP or a mobile phone, etc.

[0053] 1. Activate the fuel cell controller to complete system function output: When the fuel cell system needs to activate the fuel cell controller to complete functions such as winter parking cleaning, and when there are no maintenance personnel present or no vehicle key available temporarily, the fuel cell controller can be activated by sending information via the cloud platform APP or mobile phone to wake up the data acquisition controller. The data acquisition controller then outputs a high voltage through the level drive module to wake up the fuel cell controller, thereby starting the fuel cell system and realizing functions such as winter parking cleaning.

[0054] 2. Wake up and activate the fuel cell controller to complete the program update: When the fuel cell controller program needs to be updated, when there are no maintenance personnel present in the vehicle or when there is no available vehicle key, and the fuel cell controller is not woken up by operating the key or by a simpler and smarter method, the data acquisition controller can also be woken up by sending a message through the cloud platform APP or mobile phone. The data acquisition controller then wakes up the fuel cell controller by outputting a high voltage through the level drive module, and then sends the update program to the data acquisition controller through the cloud platform APP or mobile phone. The data acquisition controller then updates the program and sends it to the fuel cell controller, thereby realizing the fuel cell controller program update.

[0055] 3. If, after the operation is completed, the data acquisition controller is put into sleep mode through the cloud platform, and the data acquisition controller is in sleep mode and does not activate the fuel cell controller, the fuel cell controller will then return to sleep mode.

[0056] This embodiment enables the fuel cell controller to be woken up anytime, anywhere, either remotely or wirelessly, regardless of whether on-site maintenance personnel are present or whether a key is available. Furthermore, this solution also enables a sleep / standby function, allowing the controller to be put into sleep mode at any time when not in use, thus saving energy.
