Abstract

The application discloses a hydrogen energy motorcycle sliding energy self-starting type control method, device and system. The method comprises the following steps: when an auxiliary battery is in a power shortage state and a current vehicle is in a sliding state, a sliding energy regeneration unit is controlled to start a rectification process, so that the counter electromotive force of the vehicle motor is rectified into direct current, the direct current is adjusted to the rated voltage of an electromagnetic valve, and the direct current is output to the electromagnetic valve to open the electromagnetic valve, so as to restore fuel cell power generation. The embodiment breaks through the technical bottleneck that the existing hydrogen energy motorcycle relies on an auxiliary battery to realize valve power supply and vehicle starting, and can obtain energy on site only by relying on the motor counter electromotive force generated by vehicle sliding. The electromagnetic valve is directly driven to be opened through rectification and voltage regulation, without external charging and battery replacement, so that the starting failure problem caused by low-temperature storage, long-term parking and battery aging is effectively solved.

Description

Technical Field

[0001] This invention relates to the field of hydrogen fuel cell vehicle control technology, specifically to a method, device, and system for self-starting control of gliding energy in hydrogen-powered motorcycles. Background Technology

[0002] Currently, hydrogen fuel cell motorcycles, as zero-emission transportation tools, have seen initial applications in high-frequency, short-distance scenarios such as ride-sharing and express delivery in recent years. However, existing hydrogen fuel cell motorcycles generally face the following technical challenges during the startup phase: Starting the hydrogen fuel cell motorcycle is rigidly dependent on the auxiliary battery. The current hydrogen fuel cell motorcycle's exhaust system (hydrogen storage tank solenoid valve, vent valve, and proportional valve) requires power from the auxiliary battery to operate, making vehicle starting entirely dependent on it. If the auxiliary battery becomes depleted due to low temperatures, aging, or prolonged storage, the solenoid valve cannot open, hydrogen cannot be supplied to the fuel cell stack, and the vehicle cannot start. This positive feedback loop is particularly pronounced in low-power hydrogen fuel cell motorcycles (300W-1000W), where the auxiliary battery capacity is smaller, the vent depth is greater, and the probability of depletion is much higher than in larger vehicles.

[0003] Coasting energy recovery is independent of the exhaust and power supply systems. Coasting energy recovery is an energy-saving technology for hydrogen-powered motorcycles, but in current technologies, the recovered energy can usually only be used to charge auxiliary batteries or supercapacitors. It can only be used by other loads after two conversions: battery charging and battery discharging. The energy utilization rate is low, and coasting energy recovery has never been used to directly power the exhaust and power supply valves. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention discloses a method, device, and system for self-starting control of gliding energy in hydrogen-powered motorcycles. This system utilizes gliding energy to directly power valves, thereby enabling the vehicle to start automatically.

[0005] The first aspect of this invention discloses a self-starting control method for the coasting energy of a hydrogen-powered motorcycle, comprising: In response to the user's start command, and by detecting the power supply status of the solenoid valve, when the power supply status of the solenoid valve is detected to be disconnected, it is determined whether the auxiliary battery is in a low-power state. When the auxiliary battery is low on power, the vehicle speed is collected to determine whether the current vehicle speed is greater than the set speed threshold. If the vehicle speed is greater than the set speed threshold, the vehicle is determined to be in a coasting state. The control coasting energy regeneration unit initiates the rectification process to rectify the back electromotive force of the vehicle's electric motor into direct current, and adjusts the direct current to the rated voltage of the solenoid valve. The output of the solenoid valve opens the solenoid valve to restore fuel cell power generation.

[0010] As an optional implementation, in a second aspect of the present invention, determining whether the auxiliary battery is in a depleted state includes: Read the current voltage of the auxiliary battery, and determine whether the current voltage is lower than a set voltage threshold based on the current voltage.

[0011] The third aspect of this invention discloses a self-starting control system for the coasting energy of a hydrogen-powered motorcycle, comprising an electric motor, a coasting energy regeneration unit, a valve direct supply unit, a solenoid valve, a power supply status detection unit, and a central controller. The input terminal of the coasting energy regeneration unit is connected to the stator winding of the electric motor, used to convert the back electromotive force of the electric motor into DC power during coasting. The input terminal of the valve direct supply circuit is connected to the power supply terminal of the solenoid valve through a voltage regulation circuit, so that the solenoid valve is directly driven to open when the coasting energy regeneration unit has power output. The power supply status detection unit is connected to the valve direct supply circuit, used to monitor the voltage status of the solenoid valve power supply terminal in real time, and outputs a self-starting trigger signal to the central controller when the power supply to the solenoid valve is detected to be interrupted. The central controller is connected to the power supply status detection unit and the coasting energy regeneration unit respectively, used to control the coasting energy regeneration unit to start the rectification process when the auxiliary battery is in a depleted state, to rectify the back electromotive force of the vehicle electric motor into DC power, and adjust the DC power to the rated voltage of the solenoid valve to open the solenoid valve, thereby restoring fuel cell power generation.

[0012] As an optional implementation, in a third aspect of the present invention, the coasting capacity regeneration unit includes a three-phase full-bridge rectifier circuit, a synchronous rectifier controller, and a voltage adapter circuit. The input terminal of the three-phase full-bridge rectifier circuit is connected to the stator winding of the motor. The synchronous rectifier controller is connected to the three-phase full-bridge rectifier circuit and is used to control the three-phase full-bridge rectifier circuit to be in a synchronous rectification state. The voltage adapter circuit is connected to the output terminal of the three-phase full-bridge rectifier circuit and is used to stabilize the DC power output by the three-phase rectifier circuit to the rated voltage of the solenoid valve after Buck-Boost conversion.

[0013] As an optional implementation, in the first aspect of the present invention, the power supply status detection unit includes a voltage sampling circuit and a comparator circuit. The voltage sampling circuit is connected to the power supply terminal of the solenoid valve through a valve direct supply circuit to monitor the voltage signal at the power supply terminal of the solenoid valve in real time and send it to the central controller and the comparator circuit. The comparator circuit is used to compare the voltage signal with a set voltage threshold.

[0014] As an optional implementation, in the first aspect of the present invention, a gas supply proportional valve driving unit and a gas supply proportional valve are further included. The input end of the gas supply proportional valve driving unit is connected to the output end of the sliding energy regeneration unit, and is used to drive the gas supply proportional valve to open so that hydrogen enters the fuel cell.

[0015] A fourth aspect of the present invention discloses an electronic device, comprising: a memory storing executable program code; a processor coupled to the memory; the processor calling the executable program code stored in the memory to execute the self-starting control method for gliding energy of a hydrogen-powered motorcycle disclosed in the first aspect of the present invention.

[0016] The fifth aspect of this invention discloses a computer-readable storage medium storing a computer program, wherein the computer program causes a computer to execute the self-starting control method for gliding energy of a hydrogen-powered motorcycle disclosed in the first aspect of this invention.

[0017] Compared with the prior art, the embodiments of the present invention have the following beneficial effects: This invention utilizes the control logic of directly supplying the solenoid valve with the rectified back EMF of the coasting motor. It fundamentally overcomes the technical bottleneck of existing hydrogen fuel cell motorcycles that rely on auxiliary batteries for valve power supply and vehicle starting. When the solenoid valve is de-energized or the battery is depleted, energy can be extracted locally solely from the back EMF generated by the vehicle's coasting motion. This energy is directly driven to open the solenoid valve through rectification and voltage regulation, eliminating the need for external charging or battery replacement. The vehicle can be automatically started simply by pushing or coasting downhill, significantly improving its environmental adaptability and effectively solving starting failure problems caused by low-temperature storage, long-term parking, and battery aging. By directly regulating the voltage of the rectified DC power and supplying it to the solenoid valve, the intermediate battery charging and discharging steps are eliminated, avoiding energy losses associated with electrochemical energy storage. Compared to traditional solutions, this reduces energy consumption by 10%–20%. The energy loss is significantly reduced, and the utilization rate of limited coasting electric energy in low-power vehicles is greatly improved. The embodiment uses the power supply status of the solenoid valve as a prerequisite for starting judgment. It first checks the power supply, then judges the power depletion, and finally judges the coasting condition, with a clear control hierarchy. Coasting electric energy directly drives the solenoid valve, eliminating the need for the software and hardware control logic of the solenoid valve's controlled switch. The solenoid valve does not require the controller to issue additional drive commands when it is energized, reducing the controller's computational load and component failure points. It also reduces the risk of gas supply failure caused by control system software failure and switch device damage. Coasting energy harvesting is only activated when the battery is depleted or the valve loses power. Under normal operating conditions, the original vehicle battery power supply logic is used, which takes into account the stability of normal driving. At the same time, it can rely on the power priority allocation rule to prioritize the power supply of the solenoid valve when the power is insufficient, so as to maximize the uninterrupted hydrogen supply link. It is especially suitable for the use scenarios of express delivery and short-distance shared hydrogen motorcycles with high frequency of start-stop and easy power depletion, reducing vehicle operation and maintenance costs.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that the terms "first," "second," "third," "fourth," etc., in the specification and claims of this invention are used to distinguish different objects, not to describe a specific order. The terms "comprising" and "having," and any variations thereof, in the embodiments of this invention are intended to cover non-exclusive inclusion. Exemplarily, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or devices.

[0022] This invention discloses a method, device, electronic equipment, and storage medium for self-starting control of gliding energy in hydrogen-powered motorcycles. The embodiment relies on the control logic of directly supplying the back electromotive force of the gliding motor to the solenoid valve through rectification. This fundamentally overcomes the technical bottleneck of existing hydrogen-powered motorcycles that rely on auxiliary batteries for valve power supply and vehicle starting. When the solenoid valve is de-energized or the battery is depleted, energy can be extracted locally solely from the back electromotive force generated by the motor during vehicle gliding. This energy is directly driven to open the solenoid valve through rectification and voltage regulation, eliminating the need for external charging or battery replacement. The vehicle can be self-started simply by pushing or gliding downhill, significantly improving its environmental adaptability and effectively solving starting failure problems caused by low-temperature storage, long-term parking, and battery aging. By directly regulating the voltage of the rectified DC power and supplying it to the solenoid valve, the intermediate battery charging and discharging steps are eliminated, avoiding energy loss from electrochemical energy storage. Compared to traditional solutions, this can reduce energy consumption by 10%–20%. The energy loss is significantly reduced, and the utilization rate of limited coasting electric energy in low-power vehicles is greatly improved. The embodiment uses the power supply status of the solenoid valve as a prerequisite for starting judgment. It first checks the power supply, then judges the power depletion, and finally judges the coasting condition, with a clear control hierarchy. Coasting electric energy directly drives the solenoid valve, eliminating the need for the software and hardware control logic of the solenoid valve's controlled switch. The solenoid valve does not require the controller to issue additional drive commands when it is energized, reducing the controller's computational load and component failure points. It also reduces the risk of gas supply failure caused by control system software failure and switch device damage. Coasting energy harvesting is only activated when the battery is depleted or the valve loses power. Under normal operating conditions, the original vehicle battery power supply logic is used, which takes into account the stability of normal driving. At the same time, it can rely on the power priority allocation rule to prioritize the power supply of the solenoid valve when the power is insufficient, so as to maximize the uninterrupted hydrogen supply link. It is especially suitable for the use scenarios of express delivery and short-distance shared hydrogen motorcycles with high frequency of start-stop and easy power depletion, reducing vehicle operation and maintenance costs.

[0023] Example 1 Please see Figure 1 , Figure 1 This is a flowchart illustrating a self-starting control method for the gliding energy of a hydrogen-powered motorcycle, as disclosed in an embodiment of the present invention. The execution entity of the method described in this embodiment is an execution entity composed of software and / or hardware. This execution entity can receive relevant information via wired or / or wireless means and can send certain instructions. It may also have certain processing and storage functions. This execution entity can control multiple devices, such as remote physical servers or cloud servers and related software, or local hosts or servers and related software that perform related operations on devices located in a certain location. In some scenarios, it can also control multiple storage devices, which may be placed in the same location as the device or in different locations. Figure 1 As shown, the self-starting control method for the coasting energy of this hydrogen-powered motorcycle includes the following steps: 101. Responding to the user's start command and detecting the power supply status of the solenoid valve, when the power supply status of the solenoid valve is detected to be disconnected, determine whether the auxiliary battery is in a low-power state. Determining whether the auxiliary battery is in a low-charge state includes: reading the current voltage of the auxiliary battery, and determining whether the current voltage is lower than a set voltage threshold based on the current voltage.

[0024] The user issues a vehicle start command via the vehicle key switch or start button. Upon receiving the start signal, the central controller immediately triggers the power supply status detection unit. This unit uses an onboard resistor voltage divider sampling circuit to collect the power supply voltage across the solenoid valve of the hydrogen storage tank in real time. The sampled voltage is sent to the central controller via an ADC channel, and a comparator circuit compares the real-time sampled voltage with the minimum operating voltage threshold of the solenoid valve. In actual implementation, to avoid misjudgments caused by voltage drops during driving, a short filtering time window of 200–500 ms is configured. Only when the solenoid valve voltage continuously falls below the threshold and exceeds the time window is it determined that the power supply to the solenoid valve is physically disconnected.

[0025] After determining that the solenoid valve is de-energized, the central controller retrieves the sampled voltage data from the low-voltage auxiliary battery terminal and compares the measured battery voltage with the preset start-up voltage threshold: the threshold for the 12V system is set to 10.5V, and the threshold for the 24V system is increased proportionally. If the measured voltage is lower than the threshold, it is determined that the auxiliary battery is depleted and proceeds to the next control step; if the solenoid valve is powered normally or the battery voltage is up to standard, the system directly enters the original vehicle's normal start-up process, and the coasting self-start logic is not involved.

[0026] 102. When the auxiliary battery is in a low-power state, the vehicle speed is collected to determine whether the current vehicle speed is greater than the set speed threshold. If the vehicle speed is greater than the set speed threshold, it is determined that the current vehicle is in a coasting state.

[0027] After the central controller confirms that the auxiliary battery is low on power, it retrieves the pulse signal from the vehicle speed sensor and calculates the real-time vehicle speed using the pulse frequency. The system has a pre-stored fixed low-speed threshold (standard calibration 5 km / h). The controller compares the measured vehicle speed with the calibrated threshold: if the measured speed is less than or equal to the threshold, the vehicle is considered stationary or moving at low speed. The motor's back EMF output power is insufficient to support the solenoid valve, and the automatic start-up process is paused, waiting for the user to push the vehicle. If the measured speed is greater than the set threshold, it indicates that the wheels are driving the motor to rotate passively, entering a coasting state. The motor can continuously generate induced back EMF, and the controller locks in the valid coasting state, issuing a command to start the coasting energy regeneration unit's rectification operation, and proceeds to step 103. This step filters out invalid stationary conditions by vehicle speed, avoiding wasted power consumption caused by no-load start-up rectification.

[0028] 103. Control the coasting energy regeneration unit to start the rectification process, so as to rectify the back electromotive force of the vehicle motor into DC power, and adjust the DC power to the rated voltage of the solenoid valve. Output the DC power to the solenoid valve to open the solenoid valve to restore fuel cell power generation.

[0029] The central controller outputs a control signal to start the coasting energy regeneration unit. The three-phase full-bridge rectifier circuit composed of six MOSFETs inside the unit switches to synchronous rectification mode. The alternating back electromotive force output by the three-phase windings of the motor (U / V / W) is connected to the AC input terminal of the rectifier bridge. After synchronous rectification, it outputs pulsating DC power. The pulsating DC power is sent to the Buck-Boost voltage adapter circuit. The converter relies on closed-loop voltage regulation control to automatically step up and down the voltage and regulate it to the rated operating voltage of the solenoid valve.

[0030] The regulated DC power is directly supplied to the solenoid valve power supply terminal of the hydrogen storage tank through a switchless, normally open valve direct supply circuit. The solenoid valve is energized and opens, allowing hydrogen from the storage tank to be supplied to the proportional gas supply valve via pipeline. The central controller synchronously outputs a PWM signal to drive the proportional gas supply valve to gradually open, allowing hydrogen to enter the fuel cell stack anode. The fuel cell then undergoes an electrochemical reaction and begins to output electrical energy. The fuel cell output energy is boosted by the onboard DC-DC converter and continuously replenishes the depleted auxiliary battery. Once the auxiliary battery voltage recovers to the normal recovery threshold, the system exits the coasting self-start control logic, and the vehicle switches to the fuel cell's conventional power supply mode.

[0031] Then, the system charges the auxiliary battery and shuts down the auto-start process when it detects that the current voltage of the auxiliary battery meets the normal driving voltage.

[0032] The following example, a 300W hydrogen-powered motorcycle, illustrates the coasting self-starting process: The auxiliary battery uses a low-voltage battery (such as a lead-acid or lithium battery), and the hydrogen storage tank solenoid valve has a typical low-voltage operating voltage (e.g., 12V), with a minimum operating voltage of approximately 75% of the rated value. When the vehicle is parked for an extended period, causing the auxiliary battery voltage to drop below the minimum operating voltage, the system detects a user start signal. The central controller reads the auxiliary battery voltage to determine a low-charge state; it also reads the vehicle speed from the speed sensor to obtain the current vehicle speed (above the low-speed threshold), determining that coasting is possible. The central controller sends a start command to the three-phase full-bridge rectifier circuit. The motor rotates during coasting, generating an AC back electromotive force proportional to the vehicle speed. The three-phase full-bridge operates in synchronous rectification mode, rectifying the AC back electromotive force into DC. The Buck-Boost converter boosts the rectified output to the solenoid valve's rated voltage for stable output. The valve direct supply circuit is normally open, and the voltage at the solenoid valve's power supply terminal rises from zero to the rated value. When the voltage reaches the minimum operating voltage, the solenoid valve automatically opens, and hydrogen from the storage tank enters the fuel cell stack anode via the proportional valve. After the solenoid valve opens, the proportional valve drive module receives a PWM signal from the central controller and gradually opens the proportional valve. Once hydrogen enters the fuel cell stack, the stack begins to generate electricity. When the fuel cell stack output voltage reaches the input threshold of the DC-DC converter, the DC-DC converter initiates boost conversion to charge the auxiliary battery. During charging, the central controller continuously monitors the auxiliary battery voltage. Once the auxiliary battery voltage recovers above the normal operating voltage, the central controller exits the self-starting mode, and the system switches to normal operating mode, meaning the solenoid valve power supply switches to auxiliary battery power supply.

[0033] Example 2 Please see Figure 2 , Figure 2 This is a schematic diagram of a self-starting control device for the gliding energy of a hydrogen-powered motorcycle, as disclosed in an embodiment of the present invention. Figure 2 As shown, the self-starting control device for the coasting energy of the hydrogen-powered motorcycle may include: a start-up response module 201, a low-power judgment module 202, and a coasting power generation module 203. The start-up response module 201 responds to the user's start command and detects the power supply status of the solenoid valve. When the power supply status of the solenoid valve is detected as disconnected, it determines whether the auxiliary battery is in a low-power state. The low-power judgment module 202, when the auxiliary battery is in a low-power state, collects the vehicle's speed and determines whether the current vehicle speed exceeds a set speed threshold. When the vehicle speed exceeds the set speed threshold, it determines that the vehicle is in a coasting state. The coasting power generation module 203 controls the coasting energy regeneration unit to start the rectification process, rectifying the back electromotive force of the vehicle's electric motor into direct current, and adjusting the direct current to the rated voltage of the solenoid valve to open the solenoid valve, thereby restoring fuel cell power generation.

[0034] The embodiment also includes a battery charging module: used to control the charging of the auxiliary battery, and to shut down the automatic start process when the current voltage of the auxiliary battery is detected to meet the normal driving voltage. The low-power determination module 202 determines whether the auxiliary battery is in a low-power state by: reading the current voltage of the auxiliary battery, and determining whether the current voltage is lower than a set voltage threshold based on the current voltage.

[0035] Example 3 like Figure 3 As shown in the embodiment, a self-starting control system for the coasting energy of a hydrogen-powered motorcycle is disclosed. It includes an electric motor, a coasting energy regeneration unit, a valve direct supply unit, a solenoid valve, a power supply status detection unit, and a central controller. The input terminal of the coasting energy regeneration unit is connected to the stator winding of the electric motor, used to convert the back electromotive force of the electric motor into direct current (DC) energy during coasting. The input terminal of the valve direct supply circuit is connected to the output terminal of the coasting energy regeneration unit via a voltage regulation circuit, so that the solenoid valve is directly driven to open when the coasting energy regeneration unit has power output. The power supply status detection unit is connected to the valve direct supply circuit, used to monitor the voltage status of the solenoid valve's power supply terminal in real time, and outputs a self-starting trigger signal to the central controller when a power supply interruption is detected. The central controller is connected to both the power supply status detection unit and the coasting energy regeneration unit, used to control the coasting energy regeneration unit to start a rectification process when the auxiliary battery is in a depleted state, to rectify the back electromotive force of the vehicle's electric motor into DC power, and adjust the DC power to the rated voltage of the solenoid valve to open the solenoid valve, thereby restoring fuel cell power generation.

[0036] The input terminal of the coasting energy regeneration unit is connected to the stator winding of the motor. In the coasting state, the back electromotive force of the motor is converted into DC power through three-phase rectification to provide starting power for the exhaust system. The valve direct supply circuit: the input terminal and the output terminal of the coasting energy regeneration unit do not pass through an auxiliary battery or other energy storage components. It is directly connected to the power supply terminal of the hydrogen storage tank solenoid valve through a voltage regulation circuit. When the coasting energy regeneration unit has an output, the solenoid valve is directly driven to open. The power supply status detection unit: connected to the valve direct supply circuit, monitors the voltage and current status of the solenoid valve power supply terminal in real time. When the power supply to the solenoid valve is interrupted, it triggers an automatic start signal. Gas supply proportional valve drive module: The input end is connected to the output end of the coasting energy regeneration unit, used to drive the gas supply proportional valve to allow hydrogen to enter the fuel cell stack during self-starting; Central controller: Connected to the power supply status detection unit and the coasting energy regeneration unit, when the auxiliary battery voltage is lower than the start-up threshold, the central controller responds to the self-starting signal and controls the coasting energy regeneration unit to perform three-phase rectification start-up; The electrical energy output by the coasting energy regeneration unit directly energizes the solenoid valve to open through the valve direct supply circuit, and hydrogen enters the fuel cell stack through the gas supply proportional valve, and the fuel cell stack begins to generate electricity. Voltage Furthermore, the coasting capability regeneration unit includes a three-phase full-bridge rectifier circuit, a synchronous rectifier controller, and a voltage adapter circuit. The input terminal of the three-phase full-bridge rectifier circuit is connected to the stator winding of the motor. The synchronous rectifier controller is connected to the three-phase full-bridge rectifier circuit and is used to control the three-phase full-bridge rectifier circuit to be in synchronous rectification mode. The voltage adapter circuit is connected to the output terminal of the three-phase full-bridge rectifier circuit and is used to stabilize the DC power output by the three-phase rectifier circuit to the rated voltage of the solenoid valve after Buck-Boost conversion. The three-phase full-bridge rectifier circuit consists of six power MOSFETs, with three AC input terminals connected to the U, V, and W phase stator windings of the motor, respectively. The synchronous rectifier controller is connected to the gate of the MOSFETs in the three-phase full-bridge rectifier circuit, enabling the MOSFETs to operate in synchronous rectification mode during coasting self-starting to reduce rectification losses. The voltage regulation circuit adopts a Buck-Boost topology. The input is connected to the three-phase rectifier output, and the output is connected in parallel to the power supply terminals of the solenoid valve and the proportional gas supply valve. The target voltage closed-loop control of the Buck-Boost converter is set to the rated operating voltage of the solenoid valve, and the output voltage can be established automatically without the intervention of the central controller.

[0037] As a preferred solution, the power supply status detection unit includes a voltage sampling circuit and a comparator circuit. The voltage sampling circuit is connected to the power supply terminal of the solenoid valve through the valve direct supply circuit to monitor the voltage signal at the solenoid valve's power supply terminal in real time and send it to the central controller and comparator circuit. The comparator circuit compares the voltage signal with a set voltage threshold. The voltage at the solenoid valve's power supply terminal is divided by resistors and connected to the ADC input pin of the MCU. Simultaneously, the midpoint of the voltage divider is connected to the non-inverting input of the comparator, and the inverting input is connected to the reference voltage (corresponding to the minimum operating voltage of the solenoid valve). When the power supply voltage is lower than the minimum operating voltage for a continuous period exceeding a set time window (to filter out instantaneous fluctuations), the comparator output flips, triggering an MCU interrupt. The MCU determines that the solenoid valve power supply is interrupted based on the interrupt signal and initiates the self-starting protection process.

[0038] In addition, the embodiment also includes a gas supply proportional valve drive unit and a gas supply proportional valve. The input end of the gas supply proportional valve drive unit is connected to the output end of the sliding energy regeneration unit and is used to drive the gas supply proportional valve to open so that hydrogen can enter the fuel cell.

[0039] The implementation is divided into four priorities, and energy scheduling is performed according to the four priorities: the first priority is the valve direct supply circuit, and the solenoid valve maintains power supply; the second priority is the standby and regulation power supply of the gas supply proportional valve; the third priority is the charging of the low-voltage auxiliary battery; and the fourth priority is the feedback to the DC bus to power the motor controller.

[0040] When the self-start mode is executed, the central controller receives an interrupt signal from the power supply status detection unit, determines whether the auxiliary battery voltage is lower than the start-up threshold, and controls the coasting energy regeneration unit to output DC power, which is adjusted to the rated voltage of the solenoid valve through the voltage adapter circuit, directly driving the solenoid valve to open. After the solenoid valve opens, the gas supply proportional valve drive module receives the PWM signal from the central controller and gradually opens the gas supply proportional valve, allowing hydrogen to enter the fuel cell stack, enabling the fuel cell stack to start generating electricity. The output voltage is boosted by DC-DC to charge the auxiliary battery and power the vehicle. After the auxiliary battery voltage recovers to above the normal start-up threshold, the central controller exits the self-start mode, and the system switches to normal operation mode.

[0041] This invention utilizes coasting energy to directly power the solenoid valve without passing through the auxiliary battery. When the auxiliary battery is completely depleted, the user can push the vehicle or coast downhill to open the solenoid valve, activate the gas supply proportioning valve, and restore fuel cell power generation, completely breaking the fault chain of "battery depletion, solenoid valve power failure, inability to supply hydrogen, and inability to generate electricity." It is particularly important to note that the solenoid valve is a critical valve in the fuel cell hydrogen supply system; its power interruption directly causes the fuel cell to shut down. This is fundamentally different from the power interruption of conventional loads such as headlights and horns, which do not affect the vehicle's basic driving ability, while the former renders the entire vehicle completely unable to start. This invention proposes a solution to this system-level start-up deadlock problem. Coasting energy recovery bypasses the dual conversion of "battery charging and discharging," directly driving the solenoid valve to open via the valve's direct power supply circuit, reducing energy conversion losses. Theoretical calculations and prototype testing show that compared to the traditional method of charging the battery before supplying power, this invention can reduce energy conversion losses by approximately 10-20%, a significant improvement particularly noticeable in low-power systems. The valve direct power supply circuit uses a normally-connected hardware connection. Once the coasting energy is established, the solenoid valve is immediately energized and opens, achieving self-starting without additional instructions from the central controller. This reduces software complexity and improves system reliability. It is particularly suitable for 300W-1000W hydrogen fuel cell motorcycles, where the auxiliary battery capacity is small and the probability of depletion is high, making the need for coasting self-starting functionality most urgent. The priority scheduling strategy of this invention ensures that the limited coasting regenerative power prioritizes power supply to the solenoid valve, guaranteeing that self-starting is always given priority.
