[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] This application discloses a centralized liquid-cooled charging control method, the flowchart of which is shown below. Figure 1 As shown, it includes:

[0051] Step S11: Obtain the current charging configuration information and charging current, wherein the charging configuration information includes at least: the number and identification information of the liquid-cooled charging devices currently charging the powered device;

[0052] Step S12: Determine whether the centralized liquid-cooled charging control system has malfunctioned based on the judgment results of the charging configuration information and whether the charging current is matched.

[0053] Step S13: If no fault is found, control the water pump speed and fan speed in the liquid cooling central station to match the charging current, and control the speed of the secondary pressurization pump and the opening of the flow control valve on different heat dissipation lines based on the charging configuration information; wherein, each heat dissipation line dissipates heat for one liquid cooling charging device, and different heat dissipation lines dissipate heat for different liquid cooling charging devices, and the liquid cooling central station can simultaneously cool the high-temperature liquid at the liquid cooling charging device that is fed back through multiple heat dissipation lines.

[0054] Currently, the market typically only offers liquid cooling systems capable of cooling a single charging device. These systems operate continuously, resulting in high energy consumption and maintenance costs. This solution, however, allows for simultaneous liquid cooling of multiple charging devices within a single system, reducing energy consumption and maintenance costs. Furthermore, the centralized liquid cooling charging control system disclosed in this solution can simultaneously cool multiple devices, requiring only pre-installed quick-connect fittings for external piping. This simplifies external wiring connections as the devices can be directly connected to the main system piping during installation.

[0055] In addition, in highly polluted areas such as mines, beaches, and chemical plants, the IP54 protection level of the charger is insufficient to protect it, requiring regular maintenance and upkeep. However, with a large number of charging stations, operators cannot perform timely and effective cleaning and maintenance. As a result, the lifespan of the charger is shorter in this environment. This solution can upgrade the protection level of the liquid-cooled charging equipment to IP65, solving the protection problem of liquid-cooled charging equipment, extending its service life and reducing the product's operation and maintenance costs.

[0056] Secondly, in the scheme disclosed in this embodiment, the internal and external environments of the liquid-cooled charging equipment are isolated, and the heat is carried away by the liquid. The liquid-cooled charging equipment itself no longer has heat dissipation devices such as fans, which can eliminate the noise generated when the liquid-cooled charging equipment itself dissipates heat. The liquid-cooled centralized station can use larger heat sinks and cooling fans to make the heat dissipation area large enough, thereby reducing the speed of the cooling fan and reducing the noise of the system to below 50 decibels.

[0057] The centralized liquid-cooled charging control method disclosed in this embodiment is based on a centralized liquid-cooled charging control system that includes both a charging system and a liquid-cooling heat dissipation system. The charging system includes liquid-cooled charging equipment, while the liquid-cooling heat dissipation system includes a liquid-cooled centralized station, line control equipment, and an electronic flow meter. The liquid-cooled central controller is used to control the liquid-cooling heat dissipation system to cool the charging system based on the current feedback from the charging system.

[0058] Liquid cooling stations are typically equipped with multi-stage variable frequency speed-regulating water pumps, radiators, speed-regulating cooling fans, water / oil tanks, electronic flow meters, pressure transmitters, temperature sensors, etc., to centrally cool the high-temperature liquid circulating back from the liquid-cooled charging equipment.

[0059] The liquid-cooled charging equipment may include: a liquid-cooled charging host, liquid-cooled engineering cables, and liquid-cooled charging terminals. The liquid-cooled charging host is a liquid-cooled module with a fully enclosed shell design and a protection rating of up to IP65. During operation, heat is dissipated through internal and external liquid circulation and then flows through pipelines to a centralized liquid-cooling station for further cooling. The liquid-cooled charging terminal is used to connect to and provide DC power to the receiving device, which can be a vehicle to be charged. The terminal uses a liquid-cooled charging gun with internal liquid piping. During operation, heat is dissipated from the charging gun through internal and external liquid circulation. The terminal itself does not have a built-in heat dissipation device and can be designed with a fully enclosed structure, achieving a protection rating of up to IP65. Typically, one liquid-cooled charging host is equipped with 10 liquid-cooled charging guns. The liquid-cooled engineering cable, or liquid-cooled engineering wiring, has internal heat dissipation piping. During operation, heat is dissipated from the liquid-cooled engineering cable through internal and external liquid circulation.

[0060] In this embodiment, the liquid-cooled charging device cools down by liquid cooling, so the liquid-cooled charging host is actually a liquid-cooled host. If the liquid-cooled charging terminal is a charging gun, then the charging gun is actually a liquid-cooled charging gun, or it can be represented as a liquid-cooled gun.

[0061] The liquid in the heat dissipation pipes can be antifreeze, silicone oil, etc., and the antifreeze can be water or ethylene glycol.

[0062] Specifically, the centralized liquid-cooled charging control method disclosed in this embodiment is based on a liquid-cooled central controller. The liquid-cooled central controller is connected to the liquid-cooled centralized station, the liquid-cooled charging equipment, and the line control equipment in each heat dissipation line. It can also be connected to the electronic flow meter in each heat dissipation line. It can obtain data fed back from the liquid-cooled centralized station and the liquid-cooled charging equipment, and control the liquid-cooled centralized station and the line control equipment based on the data fed back from the liquid-cooled centralized station and the liquid-cooled charging equipment, and adjust the liquid flow rate to achieve heat dissipation for each liquid-cooled charging equipment.

[0063] Each heat dissipation line includes at least an electronic flow meter, line control equipment, and liquid-cooled charging equipment. The liquid-cooled charging equipment includes a liquid-cooled charging host, a liquid-cooled engineering cable, and a liquid-cooled charging terminal. The electronic flow meter can count the liquid flow inside the liquid-cooled engineering cable on the current heat dissipation line. The line control equipment includes at least a secondary pressurizing pump and a flow control valve. The liquid flow inside the liquid-cooled engineering cable on the current heat dissipation line is adjusted by adjusting the speed of the secondary pressurizing pump and / or adjusting the opening of the flow control valve.

[0064] It should be noted that the secondary booster pump does not necessarily correspond one-to-one with the heat dissipation circuit. It can be that there is a secondary booster pump on each heat dissipation circuit, or several heat dissipation circuits can share a single secondary booster pump.

[0065] The system architecture diagram of the liquid cooling system and charging system in the centralized liquid-cooled charging control system can be as follows: Figure 2 As shown, it includes: a liquid cooling central station, multiple secondary pressurization pumps, and flow control valves and electronic flow meters included in the heat dissipation circuit.

[0066] In this embodiment, different parts of the liquid-cooled charging device are cooled by different secondary pressurizing pumps. For example, secondary pressurizing pump A controls the heat dissipation of the liquid-cooled charging host, secondary pressurizing pump B controls the heat dissipation of the liquid-cooled engineering cables on different heat dissipation lines, and secondary pressurizing pump C controls the heat dissipation of the liquid-cooled charging terminals on different heat dissipation lines. The heat dissipation line corresponding to the liquid-cooled charging host includes flow control valve A, electronic flow meter A1, and liquid-cooled charging host n. The heat dissipation line corresponding to the liquid-cooled engineering cable includes flow control valve Bn, electronic flow meter Bn, and liquid-cooled engineering cable 10n. The heat dissipation line corresponding to the liquid-cooled charging terminal includes flow control valve Cn, electronic flow meter Cn, and liquid-cooled charging terminal 10n.

[0067] It should be noted that, Figure 2 In the diagram, thin arrows represent cryogenic liquids, while thick arrows represent high-temperature liquids, and the direction of the arrows indicates the flow direction of the liquids. Specifically, the cooling liquid's temperature rises at the liquid-cooled charging equipment, becoming a high-temperature liquid. It then flows to the centralized liquid cooling station, where it undergoes centralized cooling, lowering its temperature to become a cryogenic liquid. This cryogenic liquid then travels through various cooling lines to the liquid-cooled charging equipment, continuing to provide liquid cooling for the equipment.

[0068] At the start of charging, the user first unplugs the charging gun from the liquid-cooled charging device and activates it to charge the receiving device. After activation, the liquid-cooling central station starts up, activating the liquid-cooling structure for the charging device, as well as all components in the charging and heat dissipation circuits containing the charging gun. Additionally, after activation, the charging gun establishes a communication handshake with the receiving device and begins insulation testing.

[0069] After all devices are started, the liquid-cooled central controller obtains the charging current and charging configuration information. The charging current is the current when the liquid-cooled charging device charges the receiving device. The charging configuration information is which liquid-cooled charging devices are currently charging the receiving device. The charging configuration information includes the number and identification information of these liquid-cooled charging devices. For example, if there are currently two liquid-cooled charging devices charging the receiving device, they are the second liquid-cooled charging device and the fourth liquid-cooled charging device.

[0070] After the liquid-cooled central controller obtains the above charging configuration information and charging current, it determines whether the charging current is abnormal based on the charging configuration information. That is, the liquid-cooled central controller has pre-stored different numbers of liquid-cooled charging devices that are charging and corresponding to different charging currents. If the charging configuration information and charging current do not correspond to the pre-stored information, it indicates that there is an abnormality, that is, the centralized liquid-cooled charging control system has malfunctioned.

[0071] For example, if there are three pre-stored liquid-cooled charging devices charging the receiving device, the charging current obtained by the liquid-cooled central controller should be the first current. However, based on the current charging configuration information, it can be determined that there are three liquid-cooled charging devices charging the receiving device, but the charging current obtained is the second current. Since the second current is different from the first current, it indicates that the current charging configuration information and the charging current do not match, and there is a fault in the system.

[0072] If it is determined that there is no fault in the current centralized liquid cooling charging control system, the subsequent charging and liquid cooling process will continue. That is, the speed of the water pump and the speed of the fan in the centralized liquid cooling station will be matched with the charging current, and the speed of the secondary pressurization pump and the opening of the flow control valve on different heat dissipation lines will be controlled based on the charging configuration information.

[0073] The total charging current varies across all lines, resulting in different pump and fan speeds in the liquid-cooled central station. A higher total charging current indicates more liquid-cooled charging devices charging the equipment, requiring more liquid for cooling, thus necessitating higher pump and fan speeds in the liquid-cooled central station. Conversely, a lower total charging current indicates fewer liquid-cooled charging devices charging the equipment, requiring less liquid for cooling, thus necessitating lower pump and fan speeds in the liquid-cooled central station.

[0074] Therefore, it is necessary to control the pump speed and fan speed in the liquid cooling central station based on the charging current so that the pump speed and fan speed match the charging current.

[0075] Furthermore, based on the charging configuration information, it can be determined which liquid-cooled charging device is currently charging the receiving device. Therefore, it is necessary to control the speed of the secondary pressurization pumps and the opening of the flow control valves on different heat dissipation lines based on the charging configuration information. For example, if the liquid-cooled charging device on the first heat dissipation line is charging the receiving device, then the flow control valve on the first heat dissipation line needs to be opened, and at the same time, the speed of the secondary pressurization pump on the first heat dissipation line needs to be matched with the charging current of the liquid-cooled charging device on that line. If the liquid-cooled charging device on the second heat dissipation line is not charging the receiving device, then the flow control valve on the second heat dissipation line needs to be closed, and the speed of the secondary pressurization pump on the second heat dissipation line needs to be reduced, or the secondary pressurization pump on the second heat dissipation line can be directly shut down to ensure precise heat dissipation for the operating liquid-cooled charging device.

[0076] The centralized liquid-cooled charging control method disclosed in this embodiment obtains the current charging configuration information and charging current. The charging configuration information includes at least: the number and identification information of the liquid-cooled charging devices currently charging the powered equipment; it determines whether the centralized liquid-cooled charging control system has malfunctioned based on the judgment result of whether the charging configuration information and the charging current match; if it is determined that no malfunction has occurred, it controls the water pump speed and fan speed in the centralized liquid-cooling station to match the charging current, and controls the speed of the secondary pressurization pumps and the opening of the flow control valves on different heat dissipation lines based on the charging configuration information; each heat dissipation line dissipates heat for one liquid-cooled charging device, and different heat dissipation lines dissipate heat for different liquid-cooled charging devices, and the centralized liquid-cooling station can simultaneously centrally cool the high-temperature liquid at the liquid-cooled charging devices that are fed back through multiple heat dissipation lines. This embodiment uses a centralized liquid cooling station to simultaneously cool different liquid-cooled charging devices on different lines. It can also control the liquid flow rate on different cooling lines based on charging configuration information. This enables a centralized liquid-cooled charging control system to simultaneously cool different liquid-cooled charging devices, and different lines can be controlled differently based on different needs. This improves work efficiency, reduces power consumption and maintenance costs, and also reduces the complexity of the system and piping for cooling liquid-cooled charging devices when multiple liquid-cooled charging devices are working.

[0077] This embodiment discloses a centralized liquid-cooled charging control method, the flowchart of which is shown below. Figure 3 As shown, it includes:

[0078] Step S31: Obtain the current charging configuration information and charging current, wherein the charging configuration information includes at least: the number and identification information of the liquid-cooled charging devices currently charging the powered device;

[0079] Step S32: Determine whether the centralized liquid-cooled charging control system has malfunctioned based on the charging configuration information and the judgment result of whether the charging current matches.

[0080] Step S33: If it is determined that no fault has occurred, control the water pump speed and fan speed in the liquid cooling central station to match the charging current, and control the speed of the secondary pressurization pump and the opening of the flow control valve on different heat dissipation lines based on the charging configuration information; wherein, each heat dissipation line dissipates heat for one liquid cooling charging device, and different heat dissipation lines dissipate heat for different liquid cooling charging devices, and the liquid cooling central station can simultaneously cool the high-temperature liquid at the liquid cooling charging device that is fed back through multiple heat dissipation lines.

[0081] Step S34: Obtain liquid cooling parameter information in the liquid cooling central station and obtain heat dissipation demand information of the liquid cooling charging equipment. The liquid cooling parameter information is related to the water pump speed and fan speed in the liquid cooling central station.

[0082] Step S35: Adjust the pump speed and fan speed in the liquid cooling station based on the heat dissipation demand information and liquid cooling parameter information, so that the liquid cooling parameter information obtained after adjusting the pump speed and fan speed matches the heat dissipation demand information.

[0083] At the start of charging, the speed of the water pump and the speed of the fan in the liquid cooling station are controlled by the charging current. During the charging process, it is necessary to continuously monitor the liquid cooling parameters and the heat dissipation requirements of the liquid cooling charging equipment in the liquid cooling station so as to adjust the speed of the water pump and the speed of the fan in the liquid cooling station based on the liquid cooling parameters and heat dissipation requirements.

[0084] Liquid cooling parameters include at least the following data: liquid flow rate, pressure, and temperature within the liquid cooling station. The rotation of the water pumps and fans within the liquid cooling station causes the cooling liquid to cool, resulting in changes in pressure and temperature. Therefore, adjusting the pump and fan speeds will correspondingly alter the liquid cooling parameters. Additionally, the liquid flow rate is related to the speed of the secondary booster pump and the opening of the flow control valve.

[0085] The heat dissipation requirements of liquid-cooled charging equipment can be measured in terms of heat dissipation, such as temperature. During charging, the liquid-cooled charging equipment continuously supplies power to the receiving device, thus requiring continuous heat dissipation. The centralized liquid cooling station cools the high-temperature liquid returning from the liquid-cooled charging equipment and transfers it back to the liquid-cooled charging equipment. Therefore, the temperature at the liquid-cooled charging equipment will also continuously change, necessitating continuous temperature monitoring.

[0086] During the charging process, after obtaining the liquid cooling parameter information and the heat dissipation requirement information of the liquid cooling charging equipment in the liquid cooling central station, the water pump speed and fan speed in the liquid cooling central station are adjusted based on the heat dissipation requirement information and the liquid cooling parameter information, so that the liquid cooling parameter information obtained after adjusting the water pump speed and fan speed matches the heat dissipation requirement information.

[0087] The above process is continuously and dynamically adjusted during charging to ensure that the cooling efficiency of the water pump speed and fan speed in the liquid cooling station can meet the heat dissipation requirements of the liquid-cooled charging equipment, thus avoiding the problem of excessive temperature of the liquid-cooled charging equipment.

[0088] Furthermore, it may also include:

[0089] Obtain flow data in the heat dissipation circuit, and adjust the speed of the secondary booster pump and the opening of the flow control valve on the heat dissipation circuit based on the heat dissipation demand information of the liquid-cooled charging equipment on the heat dissipation circuit, so that the flow data on the heat dissipation circuit after adjusting the speed of the secondary booster pump and the opening of the flow control valve matches the heat dissipation demand information of the liquid-cooled charging equipment on the heat dissipation circuit.

[0090] Each heat dissipation line is equipped with an electronic flow meter to detect the liquid flow rate in the liquid-cooled engineering cable on that line. The liquid flow rate on the heat dissipation line can be adjusted by controlling the opening of the flow control valve and the speed of the secondary booster pump.

[0091] Therefore, during the charging process, it is necessary to detect the liquid flow rate data of each heat dissipation line where the liquid-cooled charging equipment is performing the charging task, and adjust the liquid flow rate on the line based on the flow rate data and the heat dissipation requirements of the corresponding liquid-cooled charging equipment. This involves adjusting the opening of the flow control valve and / or the speed of the secondary booster pump to ensure that the current liquid flow rate on the line matches the heat dissipation requirements of the liquid-cooled charging equipment on that line, thereby ensuring the normal operation of the liquid-cooled charging equipment. At the same time, it also avoids wasting the power consumed by the water pumps and fans in the liquid-cooled centralized station when the flow rate is too high.

[0092] In addition, it is necessary to monitor the charging current of the liquid-cooled charging equipment on each heat dissipation line so as to determine whether the flow control valve on each heat dissipation line is closed and whether the secondary pressurization pump on each heat dissipation line is stopped based on the charging current of the liquid-cooled charging equipment on each heat dissipation line.

[0093] The charging current is monitored to determine whether the liquid-cooled charging device has started or stopped charging the device. When the liquid-cooled charging device starts charging the device, the flow control valve on the heat dissipation circuit of the device and the corresponding secondary pressurization pump need to be opened. When the liquid-cooled charging device stops charging the device, the flow control valve on the heat dissipation circuit of the device needs to be closed, and the speed of the corresponding secondary pressurization pump needs to be adjusted by either opening the secondary pressurization pump or increasing its speed.

[0094] Specifically, if the number of liquid cooling units in the liquid cooling central station is n, and one liquid cooling unit is matched with 10 liquid cooling guns, then the total number of liquid cooling guns in the system is 10n. Since the number of liquid cooling engineering cables corresponds one-to-one with the number of liquid cooling guns, the total number of liquid cooling engineering cables in the system is 10n.

[0095] The liquid cooling unit contains liquid cooling modules, each with a power of 30kW and a liquid flow rate of 12L / min when operating at full power. Since each liquid cooling unit contains m liquid cooling modules, and the modules are installed in a consistent manner, the flow balance within the unit can be ensured through piping design. It is not necessary to use flow control valves for individual modules; only the total liquid flow rate of each unit within the centralized liquid cooling station needs to meet design requirements.

[0096] The liquid cooling gun has a rated current of 600A and a normal operating liquid flow rate of 4L / min. The liquid cooling cable also has a rated current of 600A and a normal operating liquid flow rate of 4L / min. Due to the different diameters and lengths of the liquid cooling cable and the liquid cooling gun, the central controller automatically adjusts the flow rate of the secondary booster pump and the opening degree of the flow control valve during actual operation to ensure that the flow rate of each liquid cooling gun and liquid cooling cable meets the design requirements. The rated current that the liquid cooling gun and liquid cooling cable can withstand when liquid cooling is not activated is 125A.

[0097] The heat dissipation requirements of liquid-cooled charging equipment can also be expressed by the liquid supply flow rate. Therefore, the total liquid supply flow rate for all liquid-cooled charging equipment in the system is:

[0098] Z = A + B + C

[0099] Where Z is the total liquid supply flow rate, A is the liquid supply flow rate for cooling the liquid cooling module in the liquid cooling host, B is the liquid supply flow rate for cooling the liquid cooling gun, and C is the liquid supply flow rate for cooling the liquid cooling engineering cable.

[0100] Where A = n*m*12L / min, B = 10n*4L / min, C = 10n*4L / min.

[0101] Since B and C are identical and have a one-to-one correspondence, Z = A + 2C = n*m*12 + 2*10n*4. Since 10n is the maximum flow rate when all liquid cooling guns connected to the liquid cooling unit are working, only some of the liquid cooling guns are actually charging. Therefore, assuming X liquid cooling guns are charging and the current is >125A, the actual liquid cooling gun flow rate is C1 = 2*Xn*4.

[0102] In summary, the actual total liquid supply flow rate can be obtained as follows:

[0103] Z1=A+2C1=n*m*12+2*Xn*4=12*n*m+8Xn

[0104] Adjust the pump speed and fan speed based on the actual total liquid supply flow rate Z1 to match the liquid cooling parameters obtained after adjusting the pump speed and fan speed with the heat dissipation requirements.

[0105] The centralized liquid-cooled charging control method disclosed in this embodiment obtains the current charging configuration information and charging current. The charging configuration information includes at least: the number and identification information of the liquid-cooled charging devices currently charging the powered equipment; it determines whether the centralized liquid-cooled charging control system has malfunctioned based on the judgment result of whether the charging configuration information and the charging current match; if it is determined that no malfunction has occurred, it controls the water pump speed and fan speed in the centralized liquid-cooling station to match the charging current, and controls the speed of the secondary pressurization pumps and the opening of the flow control valves on different heat dissipation lines based on the charging configuration information; each heat dissipation line dissipates heat for one liquid-cooled charging device, and different heat dissipation lines dissipate heat for different liquid-cooled charging devices, and the centralized liquid-cooling station can simultaneously centrally cool the high-temperature liquid at the liquid-cooled charging devices that are fed back through multiple heat dissipation lines. This embodiment uses a centralized liquid cooling station to simultaneously cool different liquid-cooled charging devices on different lines. It can also control the liquid flow rate on different cooling lines based on charging configuration information. This enables a centralized liquid-cooled charging control system to simultaneously cool different liquid-cooled charging devices, and different lines can be controlled differently based on different needs. This improves work efficiency, reduces power consumption and maintenance costs, and also reduces the complexity of the system and piping for cooling liquid-cooled charging devices when multiple liquid-cooled charging devices are working.

[0106] This embodiment discloses a centralized liquid-cooled charging control method, the flowchart of which is shown below. Figure 4 As shown, it includes:

[0107] Step S41: Obtain the current charging configuration information and charging current, wherein the charging configuration information includes at least: the number and identification information of the liquid-cooled charging devices currently charging the powered device;

[0108] Step S42: Determine whether the centralized liquid-cooled charging control system has malfunctioned based on the judgment results of the charging configuration information and whether the charging current is matched.

[0109] Step S43: If it is determined that no fault has occurred, control the water pump speed and fan speed in the liquid cooling central station to match the charging current, and control the speed of the secondary pressurization pump and the opening of the flow control valve on different heat dissipation lines based on the charging configuration information; wherein, each heat dissipation line dissipates heat for one liquid cooling charging device, and different heat dissipation lines dissipate heat for different liquid cooling charging devices, and the liquid cooling central station can simultaneously cool the high-temperature liquid at the liquid cooling charging device that is fed back through multiple heat dissipation lines.

[0110] Step S44: If a fault is determined, identify the faulty heat dissipation circuit based on the judgment result; control the speed of the secondary booster pump on the faulty heat dissipation circuit to decrease, and control the flow control valve on the faulty heat dissipation circuit to close.

[0111] When it is determined that there is a liquid-cooled charging device in the centralized liquid-cooled charging control system that is charging the powered equipment, it is necessary to first determine whether the centralized liquid-cooled charging control system is faulty based on the charging configuration information fed back by the liquid-cooled charging device and the judgment result of whether the charging current is matched.

[0112] Only when the judgment result confirms that the centralized liquid-cooled charging control system has not malfunctioned can the power receiving equipment be charged according to the normal procedure, and the liquid-cooled charging equipment be cooled by liquid cooling at the same time.

[0113] If the judgment result indicates that the centralized liquid-cooled charging control system is faulty, it means that the charging configuration information and the charging current are mismatched. At this time, it is necessary to determine which part of the centralized liquid-cooled charging control system is faulty in order to eliminate the fault and continue charging the powered equipment.

[0114] Specifically, if it is determined that each liquid-cooled charging gun in the centralized liquid-cooled charging control system is unable to charge the powered equipment before charging begins, then the liquid-cooled centralized station in the system is faulty; if it is determined that a liquid-cooled charging gun connected to a certain liquid-cooled host in the centralized liquid-cooled charging control system is unable to charge before charging begins, then the liquid-cooled host in the current system is faulty; if it is detected that the charging current of a certain liquid-cooled charging gun is ≤125A before charging begins, while the charging current of the liquid-cooled charging guns in other liquid-cooled lines is not abnormal, then the single-path liquid-cooled engineering cable and / or liquid-cooled charging gun in the current system is faulty.

[0115] If, during the charging process, it is determined that every liquid-cooled charging gun in the centralized liquid-cooled charging control system stops charging the powered equipment, then a fault has been identified in the centralized liquid-cooled station of the system. If, during the charging process, it is determined that a liquid-cooled charging gun connected to a liquid-cooled host in the centralized liquid-cooled charging control system stops charging, then a fault has been identified in the liquid-cooled host of the current system. If, during the charging process, the charging current of a liquid-cooled charging gun is detected to drop to ≤125A, while the charging current of the liquid-cooled charging guns in other liquid-cooled lines does not show any abnormality, then a fault has been identified in the single-path liquid-cooled engineering cable and / or liquid-cooled charging gun in the current system.

[0116] In addition, during the charging process, if the temperature of a single liquid-cooled charging gun or liquid-cooled engineering cable is determined to be greater than or equal to 90°C and lasts for 2 minutes, the charging current of the liquid-cooled charging gun can be reduced to ≤125A to ensure that the liquid-cooled charging equipment can operate within the standard temperature range and avoid overheating. During the charging process, if the temperature of a single liquid-cooled charging gun or liquid-cooled engineering cable is determined to be greater than or equal to 95°C and lasts for 2 seconds, the liquid-cooled charging gun can be stopped to ensure the safe use of the liquid-cooled charging equipment.

[0117] If a fault is identified in the centralized liquid-cooled charging control system at the start of charging, the first step is to determine whether the fault lies with the centralized liquid-cooling station, the liquid-cooling main unit, the liquid-cooling engineering cable, or the liquid-cooling gun. If the fault is with the centralized liquid-cooling station, the charging current of the liquid-cooling charging equipment is set to zero, meaning charging ceases, and the centralized liquid-cooling station is inspected. If the fault is with the liquid-cooling main unit, the liquid-cooling charging equipment on the corresponding heat dissipation line of that main unit is stopped from charging the receiving device. The receiving device can then be charged using another liquid-cooling main unit to facilitate the inspection of the main unit. If the fault is with the liquid-cooling engineering cable or the liquid-cooling gun, the heat dissipation line containing the faulty cable or gun needs to be identified. The flow control valve on that heat dissipation line is closed, and the speed of the secondary booster pump on that line is reduced to facilitate the inspection of the liquid-cooling engineering cable and / or the liquid-cooling gun.

[0118] Similarly, if during the charging process, it is determined that an abnormality has occurred in the heat dissipation circuit based on the heat dissipation demand information and liquid cooling parameter information, the charging current of the liquid cooling charging equipment on the abnormal heat dissipation circuit for charging the powered equipment is adjusted; based on the adjusted charging current of the liquid cooling charging equipment on the abnormal heat dissipation circuit, the speed of the water pump and the speed of the fan in the liquid cooling centralized station, as well as the speed of the secondary booster pump and the opening of the flow control valve on the abnormal heat dissipation circuit are adjusted.

[0119] If the liquid cooling parameters do not match the heat dissipation requirements, it can be determined that there is an abnormality in the heat dissipation circuit. At this time, first identify the abnormal heat dissipation circuit and control it to stop charging, that is, adjust its charging current to 0, control the flow control valve on the heat dissipation circuit to close, and control the speed of the corresponding secondary booster pump to reduce.

[0120] Furthermore, if it is determined that no fault has occurred at the start of charging, an output current adjustment command is sent to the liquid-cooled charging equipment so that the liquid-cooled charging equipment charges the powered equipment based on the actual required current; the pump speed and fan speed in the liquid-cooled centralized station are controlled to match the actual required current.

[0121] At the start of charging, when the user establishes a connection between the liquid-cooled charging gun and the powered device, since it is uncertain whether there is a fault in the centralized liquid-cooled charging control system, an initial charging current can be set, which is the charging current in this embodiment. The powered device is charged with a small power using a small initial charging current, while the liquid-cooled central controller determines whether there is a fault in the system.

[0122] If a system malfunction is detected at this point, the initial charging current is reduced to 0, and charging is stopped. If no system malfunction is detected at this point, the liquid-cooled central controller can increase the initial charging current to the actual required current to meet the charging needs of the powered equipment. Then, the pump speed and fan speed in the liquid-cooled central station are controlled to match the actual required current, thereby ensuring the heat dissipation needs of the liquid-cooled charging equipment.

[0123] Furthermore, after charging is complete, the liquid cooling central controller, based on the communication connection between the liquid cooling charging gun and the receiving device, determines that the receiving device has finished charging. It then controls the liquid cooling charging device charging that device to stop charging, and the user disconnects the liquid cooling charging gun from the receiving device. Simultaneously, the flow control valve on the heat dissipation line containing the liquid cooling charging gun and the liquid cooling engineering cable closes, and the speed of the corresponding secondary pressurization pump on that heat dissipation line decreases, thereby reducing the liquid flow rate within the liquid cooling central station. If no other receiving devices are being charged through the system at this time, the secondary pressurization pump can be stopped, and the liquid cooling central station can be shut down.

[0124] The centralized liquid-cooled charging control method disclosed in this embodiment obtains the current charging configuration information and charging current. The charging configuration information includes at least: the number and identification information of the liquid-cooled charging devices currently charging the powered equipment; it determines whether the centralized liquid-cooled charging control system has malfunctioned based on the judgment result of whether the charging configuration information and the charging current match; if it is determined that no malfunction has occurred, it controls the water pump speed and fan speed in the centralized liquid-cooling station to match the charging current, and controls the speed of the secondary pressurization pumps and the opening of the flow control valves on different heat dissipation lines based on the charging configuration information; each heat dissipation line dissipates heat for one liquid-cooled charging device, and different heat dissipation lines dissipate heat for different liquid-cooled charging devices, and the centralized liquid-cooling station can simultaneously centrally cool the high-temperature liquid at the liquid-cooled charging devices that are fed back through multiple heat dissipation lines. This embodiment uses a centralized liquid cooling station to simultaneously cool different liquid-cooled charging devices on different lines. It can also control the liquid flow rate on different cooling lines based on charging configuration information. This enables a centralized liquid-cooled charging control system to simultaneously cool different liquid-cooled charging devices, and different lines can be controlled differently based on different needs. This improves work efficiency, reduces power consumption and maintenance costs, and also reduces the complexity of the system and piping for cooling liquid-cooled charging devices when multiple liquid-cooled charging devices are working.

[0136] Furthermore, the liquid-cooled central controller is used for:

[0137] If no fault is found, the output current adjustment command is sent to the liquid-cooled charging equipment so that the liquid-cooled charging equipment charges the powered equipment based on the actual demand current; the speed of the water pump and fan in the liquid-cooled centralized station is controlled to match the actual demand current.
