[0024] Please see Figure 1 , Figure 1 The system architecture diagram of an electrochemical production system provided in this application embodiment includes a processing module (not shown in the figure), an energy storage module 110, a first power supply module 120, a first power supply ring network, a second power supply module 130, a second power supply ring network, a first load module 140, and a second load module 150.

[0025] The processing module may include an energy management system, and can communicate with the energy storage module 110, the first power supply module 120, the first power supply ring network, the second power supply module 130, the second power supply ring network, the first load module 140, and the second load module 150 to realize scheduling and control functions.

[0026] The energy storage module 110 is connected to the first power supply module 120 and the second power supply module 130 respectively. The first power supply module 120 is connected to the first power supply ring network, and the second power supply module 130 is connected to the second power supply ring network. The first power supply ring network is connected to the first load module 140, and the second power supply ring network is connected to the second load module 150. The first power supply ring network and the second power supply ring network are electrically isolated from each other.

[0027] The energy storage module 110 can be in the megawatt range, with a high voltage platform of up to 1500V. The energy storage module 110 can be connected to the first power supply module 120 and the second power supply module 130 via a 1500V DC bus. The energy storage module 110 can serve as an energy source for the electrochemical production system.

[0028] The first load module 140 includes a self-consuming power module and an auxiliary production module of the energy storage module 110, and the second load module 150 includes a main production module and a rectifier module. The main production module and the auxiliary production module constitute an electrochemical production module. The self-consuming power module of the energy storage module 110 may include loads such as liquid cooling units, battery management systems, air conditioners, and fire protection systems. Although these loads do not directly participate in power supply, they are critical loads required for the normal operation of the energy storage module 110. The auxiliary production module can be equipment not directly related to electrochemical production. For example, in a hydrogen production system, water pumps, compressors, circulating pumps, and instruments are all auxiliary production modules. The main production module can be equipment directly related to electrochemical production. For example, in a hydrogen production system, the electrolyzer is a main production module. The rectifier module can convert AC power into DC power required by the main production module. The rectifier module can be an AC / DC converter.

[0029] The first power supply module 120 may include an isolation module and an inverter module. The isolation module converts the high-voltage DC power from the energy storage module 110 into intermediate-voltage DC power, thereby achieving electrical isolation between the first power supply ring network and the second power supply ring network. The inverter module converts the intermediate-voltage DC power into AC power required by the first load module 140. For example, the isolation module may be a DC / DC converter, and the inverter module may be a DC / AC converter; further details are omitted here.

[0030] The second power supply module 130 may include an energy storage converter, which can be used to convert the high-voltage DC power from the energy storage module 110 into lower-voltage AC power, so that the rectifier module can convert the AC power into the DC power required by the main production module.

[0031] As can be seen, the above system architecture enables the energy storage module to be independently powered without the need for an external power grid or external power source. At the same time, it eliminates the need for a power frequency transformer, reducing hardware costs and first-stage conversion losses, thereby improving the overall system efficiency and making it suitable for deployment.

[0032] To facilitate understanding, the following will be combined with Figure 2 Another electrochemical production system provided in the embodiments of this application will be described, taking hydrogen production as an example. Figure 2 The system architecture diagram of another electrochemical production system provided in the embodiments of this application includes an energy storage module 110, a first power supply module consisting of a series DC / DC and DC / AC converters, a power conversion system (PCS) as a second power supply module, an AC / DC converter as a rectifier module, a first load module consisting of an auxiliary production module of the hydrogen production system and a self-consuming power module of the energy storage module, and an electrolyzer as a second load module.

[0033] The energy storage module 110 is connected to the DC / DC converter and the PCS via a 1500V DC bus. The DC / AC converter outputs 380V AC power to supply the auxiliary equipment of the hydrogen production system and the self-consuming power module of the energy storage equipment through the first power supply ring network. The PCS outputs 690V AC power to the AC / DC converter, allowing the AC / DC converter to convert AC power to DC power according to the needs of the electrolyzer and output it to the second power supply ring network to power the electrolyzer. Further details are omitted here.

[0034] The following is combined Figure 3 This application describes a self-powered method for an electrochemical production system provided in its embodiments. Figure 3 This application provides a schematic flowchart of a self-powered method for an electrochemical production system, applied to the processing module of the electrochemical production system. The electrochemical production system further includes an energy storage module, a first power supply module, a first power supply ring network, a second power supply module, a second power supply ring network, a first load module, and a second load module. Specifically, it includes the following steps: Step 301: Obtain the current of the first voltage from the energy storage module through the first power supply module, and convert it into the current of the second voltage and input it into the first power supply ring network to supply power to the first load module through the first power supply ring network.

[0035] Wherein, the second voltage is less than the first voltage.

[0036] The energy storage module is connected to both the first power supply module and the second power supply module. The first power supply module is connected to the first power supply ring network, and the second power supply module is connected to the second power supply ring network. The first power supply ring network is connected to the first load module, and the second power supply ring network is connected to the second load module. The first power supply ring network and the second power supply ring network are electrically isolated from each other. The first load module includes a self-consuming power module and an auxiliary production module of the energy storage module. The second load module includes a main production module and a rectifier module. The main production module and the auxiliary production module constitute an electrochemical production module.

[0037] The first power supply module includes an isolation module and an inverter module; the step of obtaining a current with a first voltage from the energy storage module through the first power supply module, converting it into a current with a second voltage, and inputting it into the first power supply ring network to supply power to the first load module through the first power supply ring network includes: The isolation module converts the DC current of the first voltage obtained into the DC current of the fourth voltage, wherein the fourth voltage is less than the first voltage and greater than the second voltage. The inverter module converts the DC current of the fourth voltage into the AC current of the second voltage and inputs it into the first power supply ring network. The self-consuming power module is powered through the first power supply ring network; The auxiliary production module is powered through the first power supply ring network.

[0038] Specifically, the first power supply module draws power from the energy storage module via a DC bus. Since the energy storage module is megawatt-level, its platform voltage is relatively high and needs to be stepped down before it can supply power to the first load module. For example, the first voltage can be 1500V, the fourth voltage can be an intermediate voltage less than 1500V, and the second voltage can be 380V. The first load module requires AC power, so the first power supply module can ultimately output 380V AC power to the first power supply ring network. After the first power supply ring network is energized, the self-consuming power modules of the energy storage module, such as the liquid cooling system, battery management system, temperature control system, and fire monitoring system, can be started first, and then the auxiliary production modules, such as water pumps, compressors, circulating pumps, and instruments, can be started to prepare for electrochemical production.

[0039] As can be seen, by obtaining the current of the first voltage from the energy storage module through the first power supply module and converting it into the current of the second voltage, the first power supply ring network is input to supply power to the first load module through the first power supply ring network. This enables the energy storage module to be self-powered, without the need for an external power grid, and can operate in isolation for a long time. It also eliminates the need for a power frequency transformer and directly realizes the inversion of high voltage DC to low voltage AC, saving hardware costs and reducing power loss.

[0040] Step 302: Obtain the current of the first voltage from the energy storage module through the second power supply module, and convert it into the current of the third voltage and input it into the second power supply ring network to supply power to the second load module through the second power supply ring network.

[0041] The third voltage is greater than the second voltage and less than the first voltage.

[0042] The second power supply module includes an energy storage converter; the step of obtaining current at the first voltage from the energy storage module through the second power supply module, converting it into current at the third voltage, and inputting it into the second power supply ring network to supply power to the second load module through the second power supply ring network includes: The energy storage converter converts the DC current of the first voltage into the AC current of the third voltage and inputs it into the second power supply ring network. The rectifier module converts the AC current of the third voltage into DC current to power the main production module.

[0043] Specifically, the second power supply module draws power from the energy storage module via a DC bus. Since the energy storage module is megawatt-level, its platform voltage is relatively high and needs to be stepped down before it can supply power to the second load module. For example, the first voltage can be 1500V and the third voltage can be 690V. The second load module requires DC power, so the rectifier module also needs to convert the 690V AC power into DC power and output it to the second power supply ring network. After the second power supply ring network is energized, the main production module, such as the electrolyzer, can be started to begin hydrogen production.

[0044] In one possible embodiment, a fifth voltage can be determined based on the power demand of the main production module; the DC current of the first voltage obtained is converted into AC current of the fifth voltage by the energy storage converter and input into the second power supply ring network; the AC current of the fifth voltage is converted into DC current by the rectifier module to power the main production module. Specifically, the power demand of the main production module is dynamically changing, so the output power can be adjusted in real time by the energy storage converter. The specific value of the fifth voltage is not specifically limited here, which ensures that power is not wasted and meets production needs.

[0045] As can be seen, the self-powered method of the above-described electrochemical production system, applied to the processing module of the electrochemical production system, which also includes an energy storage module, a first power supply module, a first power supply ring network, a second power supply module, a second power supply ring network, a first load module, and a second load module, comprises the following steps: obtaining a current at a first voltage from the energy storage module through the first power supply module, converting it into a current at a second voltage, and inputting it into the first power supply ring network to power the first load module through the first power supply ring network, wherein the second voltage is less than the first voltage; obtaining a current at the first voltage from the energy storage module through the second power supply module, converting it into a current at a third voltage, and inputting it into the second power supply ring network to power the second load module through the second power supply ring network, wherein the third voltage is greater than the second voltage and less than the first voltage. Implementing this application allows for self-powered electrochemical production systems by setting up dual power supply ring networks, eliminating the need for equipment such as power frequency transformers, and enabling systems to operate independently of the power grid, thereby reducing hardware costs and significantly improving power supply efficiency.

[0046] The following is combined with Figure 4 Another self-powered method for an electrochemical production system provided in the embodiments of this application will be described. Figure 4 This is a schematic flowchart of another self-powered method for an electrochemical production system provided in an embodiment of this application. The method is applied to the processing module of the electrochemical production system, which further includes an energy storage module, a first power supply module, a first power supply ring network, a second power supply module, a second power supply ring network, a first load module, and a second load module. Specifically, it includes the following steps: Step 401: Obtain the current of the first voltage from the energy storage module through the first power supply module, and convert it into the current of the second voltage and input it into the first power supply ring network to supply power to the first load module through the first power supply ring network.

[0047] Step 402: Obtain the current of the first voltage from the energy storage module through the second power supply module, and convert it into the current of the third voltage and input it into the second power supply ring network to supply power to the second load module through the second power supply ring network.

[0048] Step 403: If the first power supply module fails, control the second power supply module to stop supplying power to the second power supply ring network.

[0049] Since the first power supply module is the power source for the first load module, the first load module cannot continue to operate normally when the first power supply module fails. Since the auxiliary production module and the main production module together constitute the electrochemical production module, and the self-consuming power module of the energy storage module is also a necessary load to maintain the normal operation of the energy storage module, the electrochemical production cannot continue to maintain production. The second load module powered by the second power supply network can achieve orderly shutdown without electrical interference, thus improving safety.

[0050] Step 404: If the second power supply module fails, control the first power supply module to continue supplying power to the first power supply ring network.

[0051] Since the second power supply module is the power source for the second load module, the second load module cannot continue to operate normally when the second power supply module fails. Since the main production module stops operating, it will not affect the auxiliary production module. Therefore, the first power supply module can operate independently to maintain the liquid cooling and safety system of the energy storage module, prevent battery thermal runaway, and maintain the operation of the auxiliary production module, making it easy to restart production at any time.

[0052] As can be seen, the self-powered method of the above-described electrochemical production system, applied to the processing module of the electrochemical production system, which also includes an energy storage module, a first power supply module, a first power supply ring network, a second power supply module, a second power supply ring network, a first load module, and a second load module, comprises the following steps: obtaining a current at a first voltage from the energy storage module through the first power supply module, converting it into a current at a second voltage, and inputting it into the first power supply ring network to power the first load module through the first power supply ring network, wherein the second voltage is less than the first voltage; obtaining a current at the first voltage from the energy storage module through the second power supply module, converting it into a current at a third voltage, and inputting it into the second power supply ring network to power the second load module through the second power supply ring network, wherein the third voltage is greater than the second voltage and less than the first voltage. Implementing this application allows for self-powered electrochemical production systems by setting up dual power supply ring networks, eliminating the need for equipment such as power frequency transformers, and enabling systems to operate independently of the power grid, thus reducing hardware costs and significantly improving power supply efficiency. It also enhances the safety of the energy storage module.

[0053] For steps not described in detail above, please refer to Figure 3 The explanations provided are omitted here.

[0054] For example, please refer to Figure 5 , Figure 5 A flowchart illustrating another self-powered method for an electrochemical production system provided in this application embodiment specifically includes the following steps: Step S1: System initialization, energy management system power-on self-test.

[0055] Step S2: Check if the 1500V DC bus is normal.

[0056] If the 1500V DC bus is not normal, proceed to step S3; if the 1500V DC bus is normal, proceed to step S4.

[0057] Step S3: Initialization failed, shutdown and display of warning message.

[0058] Step S4: The first power supply module is started, which energizes the first power supply ring network and enables the energy storage module to supply its own power.

[0059] The first power supply module draws power from the 1500V DC bus and outputs 380V AC power, which energizes the first power supply ring network and sequentially starts the liquid cooling system, battery management system, fire protection system, etc. of the energy storage module. It can be understood that the auxiliary production modules of the hydrogen production system are also ready to start at this time.

[0060] Step S5: Check if the energy storage module is in normal condition.

[0061] If the energy storage module is not in a normal state, proceed to step S6; if the energy storage module is in a normal state, proceed to step S7.

[0062] Step S6: Energy storage module malfunctions, shutdown occurs and warning message is displayed.

[0063] Step S7: The second power supply module starts up in black mode and enters the voltage / frequency control mode, energizing the second power supply ring network.

[0064] The second power supply module draws power from the 1500V DC bus and outputs 690V AC power. The rectifier module converts the 690V AC power into DC power, thus energizing the second power supply ring network.

[0065] Step S8: Hydrogen production starts, and the energy management system sequentially starts the auxiliary production module and the main production module.

[0066] The system can start the water pump, circulation system, compressor, electrolytic cell, etc. in a preset order.

[0067] Step S9: Stable offline operation.

[0068] The energy management system is used to control voltage, frequency, power and provide overload protection in real time. The first power supply module is used to provide continuous power to ensure the safety of the energy storage module. The second power supply module is used to adjust the output power in real time according to the hydrogen production demand.

[0069] Step S10, fault detection.

[0070] If there is no fault, return to S9.

[0071] Step S11: If the first power supply module fails, the entire electrochemical production system will shut down.

[0072] Step S12: If the second power supply module fails, the first power supply module operates independently.

[0073] As can be seen, the self-powered method of the above-described electrochemical production system, applied to the processing module of the electrochemical production system, which also includes an energy storage module, a first power supply module, a first power supply ring network, a second power supply module, a second power supply ring network, a first load module, and a second load module, comprises the following steps: obtaining a current at a first voltage from the energy storage module through the first power supply module, converting it into a current at a second voltage, and inputting it into the first power supply ring network to power the first load module through the first power supply ring network, wherein the second voltage is less than the first voltage; obtaining a current at the first voltage from the energy storage module through the second power supply module, converting it into a current at a third voltage, and inputting it into the second power supply ring network to power the second load module through the second power supply ring network, wherein the third voltage is greater than the second voltage and less than the first voltage. Implementing this application allows for self-powered electrochemical production systems by setting up dual power supply ring networks, eliminating the need for equipment such as power frequency transformers, and enabling systems to operate independently of the power grid, thus reducing hardware costs and significantly improving power supply efficiency. It also enhances the safety of the energy storage module.
