[0002] With the development of new energy technologies, more and more electric vehicles need to be charged at charging piles. However, to meet the security requirements of charging stations, traditional charging stations usually need to dig the ground to bury cables, and set up drainage facilities, ventilation facilities, rodent-proof facilities, etc. Moreover, in order to avoid abnormal damage during the connection of cables, it is necessary to directly connect each cabinet with a cable from the mains connection point to ensure that the waterproof performance meets the usage requirements. The installation structure of this charging station is relatively complex, and it is difficult to deploy the charging station in a short time. Also, since channels need to be set up for burying cables, traditional charging stations cannot monitor the state of the inside of the cables, and thus cannot monitor abnormal situations such as water immersion, high temperature, and high humidity in the channels in real time.

[0033] It should be further understood that the term " / and / " used in the specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the related listed items, and includes these combinations.

[0034] Please refer to Figure 1 and Figure 2, as shown in the figure, an embodiment of the present invention application provides a method for monitoring the state of an integrated power busbar base of a charging station. The method for monitoring the state of the integrated power busbar base of the charging station is applied to the monitor 61 of the state monitoring device 6. The monitor 61 is communicatively connected to the water immersion detector 62 and the temperature and humidity detector 63 in the state monitoring device 6 to achieve the transmission of data information. The monitor 61 is a terminal device disposed in the base for obtaining monitoring information and generating alarm prompt information, such as a Soc control chip, a PLC (Programmable Logic Controller) circuit board, etc. As Figure 1 shown, the method includes steps S110 to S150.

[0035] S110. Receive the accumulated water depth information detected by the water immersion detector and receive the temperature information and humidity information detected by the temperature and humidity detector.

[0036] Receive the accumulated water depth information detected by the water immersion detector and receive the temperature information and humidity information detected by the temperature and humidity detector. The monitor can receive the accumulated water depth information detected by the water immersion detector. The accumulated water depth information is also the height at which the water overflows the detection cable. If the accumulated water depth information is 0, it indicates that the water does not enter the interior of the rectangular housing at this time. Further, the monitor can also receive the temperature information and humidity information detected by the temperature and humidity detector. The temperature information can be used to reflect the current temperature inside the cabinet, and the humidity information can be used to reflect the current humidity inside the cabinet.

[0037] S120. Determine whether the accumulated water depth information meets the preset accumulated water determination condition.

[0038] Determine whether the accumulated water depth information meets the preset accumulated water determination condition. It can be determined whether the accumulated water depth information meets the accumulated water determination condition. The accumulated water determination condition is also a specific condition for determining whether the accumulated water depth meets the working requirements. If the accumulated water depth information meets the accumulated water determination condition, it indicates that the accumulated water inside the rectangular housing is within the safe range at this time; if the accumulated water depth information does not meet the accumulated water determination condition, it indicates that the accumulated water inside the rectangular housing is serious at this time and drainage treatment is required.

[0039] Further, step S120 specifically includes the following sub-steps: determining whether the accumulated water depth information is greater than the depth threshold in the accumulated water determination condition; if the accumulated water depth information is greater than the depth threshold in the accumulated water determination condition, determining whether the accumulated water duration is greater than the duration threshold corresponding to the accumulated water depth information in the accumulated water determination condition; if the accumulated water duration is greater than the corresponding duration threshold, determining that the accumulated water determination condition is not satisfied; if the accumulated water depth information is not greater than the depth threshold or the accumulated water duration is not greater than the duration threshold, determining that the accumulated water determination condition is satisfied.

[0040] Specifically, it can be determined whether the accumulated water depth information is greater than the depth threshold in the accumulated water determination condition. If it is greater than the accumulated water depth threshold, record the current time as the start time, and further obtain the duration threshold corresponding to the accumulated water depth information from the accumulated water determination condition. The accumulated water determination condition includes multiple accumulated water value intervals, and each accumulated water value interval corresponds to a duration threshold. Then, the duration threshold of the accumulated water value interval matching the accumulated water depth information can be obtained. According to the real-time obtained accumulated water depth information and the above start time, obtain the time when the accumulated water depth information is within the corresponding accumulated water value interval as the accumulated water duration, and determine whether the accumulated water duration is greater than the corresponding duration threshold. If the accumulated water duration is greater than the corresponding duration threshold, it is determined that the accumulated water determination condition is not satisfied.

[0041] S130, if the accumulated water depth information does not satisfy the accumulated water determination condition, generate a corresponding alarm prompt message.

[0042] If the accumulated water depth information does not satisfy the accumulated water determination condition, an alarm prompt message can be generated correspondingly. Among them, a communication unit can be configured in the monitor, and the alarm prompt message is sent to a monitoring server set remotely through the communication unit. The monitoring server can send the alarm prompt message to the corresponding management terminal, and then the holder of the management terminal can perform corresponding processing on the current charging station according to the received alarm prompt message. The monitor can also directly send the alarm prompt message to the management terminal of the current charging station through the communication unit, and then the holder of the management terminal can perform corresponding processing on the current charging station according to the received alarm prompt message.

[0043] S140, if the accumulated water depth information satisfies the accumulated water determination condition, determine whether the temperature information and the humidity information satisfy the preset temperature and humidity determination conditions.

[0044] If the accumulated water depth information meets the accumulated water judgment condition, determine whether the temperature information and the humidity information meet the preset temperature and humidity judgment conditions. If the accumulated water depth information meets the accumulated water judgment condition, further determine whether the temperature information and the humidity information meet the preset temperature and humidity judgment conditions; among them, the temperature threshold and the humidity threshold are configured in the temperature and humidity judgment conditions, and it can be determined whether the temperature information is greater than the preset temperature, and at the same time determine whether the humidity information is greater than the humidity threshold. Specifically, if only one temperature and humidity detector is set, the temperature value and humidity value detected by the temperature and humidity detector are obtained for use; if multiple temperature and humidity detectors are set, the temperature values detected by the multiple temperature and humidity detectors can be obtained and the average value is calculated as the temperature information, and the humidity values detected by the multiple temperature and humidity detectors are obtained and the average value is calculated as the humidity information.

[0045] If the temperature information is greater than the temperature threshold, or the humidity information is greater than the humidity threshold, it is determined that the temperature and humidity judgment conditions are not met. If the temperature information is not greater than the temperature threshold and the humidity information is not greater than the humidity threshold, it is determined that the temperature and humidity judgment conditions are met.

[0046] S150. If the temperature information and the humidity information do not meet the temperature and humidity judgment conditions, generate corresponding alarm prompt information.

[0047] If the temperature information and the humidity information do not meet the temperature and humidity judgment conditions, generate corresponding alarm prompt information. If the temperature and humidity judgment conditions are not met, corresponding alarm prompt information can also be generated. The alarm prompt information generated here is different from the alarm prompt information generated when the accumulated water judgment condition is not met in terms of content. If it is determined that the temperature and humidity judgment conditions are met, the process can return to step S110 to realize periodic monitoring of the state inside the power busbar base.

[0048] In a specific embodiment, as Figure 2 shown, the monitor 61 is communicatively connected to the fan 64 in the state monitoring device 6 to realize the transmission of data information. After the temperature information and the humidity information do not meet the temperature and humidity judgment conditions, it further includes: sending a ventilation instruction to the fan to start the fan for ventilation; after starting the fan for a preset duration, determine again whether the temperature information and the humidity information meet the preset temperature and humidity judgment conditions; if the temperature information and the humidity information do not meet the temperature and humidity judgment conditions, generate corresponding alarm prompt information.

[0049] Further, if it is determined that the temperature and humidity judgment conditions are not met, the alarm prompt information may not be generated first. At this time, the monitor sends a ventilation instruction to the fan, and the fan starts to work according to the received ventilation instruction. At this time, the fan can blow the external air flow into the rectangular housing to reduce the temperature and / or humidity inside the rectangular housing and the cabinet. The preset duration for the fan to start can be set. If the temperature information and humidity information are judged again after the fan has worked for the preset duration and still do not meet the preset temperature and humidity judgment conditions, the step of generating the corresponding alarm prompt information can be executed.

[0050] In the method for monitoring the state of the integrated power busbar base of a charging station provided by the embodiments of the present invention, the method includes: receiving the accumulated water depth information detected by a water immersion detector and receiving the temperature information and humidity information detected by a temperature and humidity detector; judging whether the accumulated water depth information meets the preset accumulated water judgment conditions; if the accumulated water depth information does not meet the accumulated water judgment conditions, generating the corresponding alarm prompt information; if the accumulated water depth information meets the accumulated water judgment conditions, judging whether the temperature information and humidity information meet the preset temperature and humidity judgment conditions; if the temperature information and humidity information do not meet the temperature and humidity judgment conditions, generating the corresponding alarm prompt information. Through the water immersion detector and temperature and humidity detector arranged inside the integrated power busbar base of the charging station, the above state monitoring method monitors the internal state of the base, so as to be able to monitor in real time whether abnormal situations such as water immersion, high temperature, and high humidity occur, and generate alarm prompt information in time, greatly improving the safety and reliability of the application of the charging station.

[0051] The embodiments of the present invention also provide a state monitoring device for an integrated power busbar base of a charging station. The state monitoring device for the integrated power busbar base of the charging station can be configured in the integrated power busbar base of the charging station, and the state monitoring device for the integrated power busbar base of the charging station is used to execute any embodiment of the foregoing method for monitoring the state of the integrated power busbar base of the charging station. Specifically, please refer to Figure 2 , the state monitoring device further includes a water immersion detector, a temperature and humidity detector, and a fan, and the monitor is communicatively connected to the water immersion detector, the temperature and humidity detector, and the fan to realize the transmission of data information.

[0052] As Figure 3 and Figure 4 shown, the integrated power busbar base includes a rectangular housing 1, a busbar 2, a heat dissipation ventilation wing guide plate 3, and a support 4; a hollow cavity is provided inside the rectangular housing 1. For the specific structure, please refer to Figure 5 and Figure 7, the heat dissipation ventilation wing guide plates 3 are all assembled on the top surface of the hollow cavity; the busbar 2 is composed of multiple wires arranged in parallel, and the wires are all arranged along the long side direction of the rectangular housing 1, and there are gaps between adjacent wires; a plurality of insulating brackets 21 are provided on the bottom surface of the busbar 2, and a fixing bracket 22 is provided between the bottom of the insulating bracket 21 and the bottom surface of the hollow cavity; the support 4 is fixedly arranged on the lower end surface of the rectangular housing 1; at least one hollow through hole is provided on the upper end surface of the rectangular housing 1, and the cabinet 5 is arranged above the rectangular housing 1 and covers the hollow through hole; a plurality of circuit breakers 23 are arranged at intervals above the busbar 2, and each circuit breaker 23 is electrically connected to the busbar 2 through a connection cable 24, and the connection cable 24 passes through the hollow through hole; at least one fan 64 is arranged in the hollow cavity, and the blowing direction of the fan 64 is from bottom to top; the water immersion detector 62 is fixedly arranged on the inner side wall of the cabinet 5, and the detection cable 621 electrically connected to the water immersion detector 62 is led out from the lower end of the water immersion detector 62 and is arranged around the outer edge of the bottom surface of the hollow cavity; the detection cable 621 is fixed to the bottom surface of the hollow cavity through a cable fixing seat 622; at least one temperature and humidity detector 63 is arranged on the top surface of the hollow cavity, and the connection wire 631 electrically connected to the temperature and humidity detector 63 is led out from one side of the temperature and humidity detector 63 and extends into the cabinet 5, and a detection probe is arranged at the end of the connection wire 631.

[0053] The upper end surface of the rectangular housing 1 serves as an equipment bearing surface for installing various cabinets 5; the hollow cavity of the rectangular housing 1 can be used as a housing for installing the busbar 2 and the heat dissipation ventilation wing guide plates 3. Since the busbar 2 is arranged in the rectangular housing 1 as a common wiring point for each circuit breaker 23, while ensuring that the waterproof performance meets the use requirements, the amount of cables is greatly reduced, and it is not necessary for each cabinet 5 to be individually electrically connected to the mains wiring point through cables, saving the cost of cables. The busbar 2 and the heat dissipation ventilation wing guide plates 3 are installed in the hollow cavity, so as to guide the internal air flow through the heat dissipation ventilation wing guide plates 3, thereby improving the heat dissipation performance and realizing the application requirements of heat dissipation and rodent prevention. And because the overall size of the rectangular housing 1 is not large, the integrated power busbar base integrates the functional components into a whole base, which is convenient for the overall migration of the cabinet 5 above it. Therefore, it has the characteristics of safety, environmental protection, small floor area and convenient migration. For convenient transportation, the size of the rectangular housing 1 can be correspondingly set based on the size of the container, that is, the length and width of the rectangular housing 1 can be set to be equal to those of the container.

[0054] The busbar 2 is fixed by combining a fixed bracket 22 and an insulating bracket 21, so that the busbar 2 is more stable, preventing the copper busbar from short - circuiting when there is a circuit break, and ensuring that the dynamic and thermal stability of the busbar 2 meets the short - circuit current requirements. Between conventional electrical equipment, there is a cable connection. In this solution, the cable connection is changed to a busbar 2 connection, reducing the laying difficulty, improving the reliability of electrical connection, and enhancing the safety level of equipment operation.

[0055] To improve the heat dissipation and moisture removal performance, a fan 64 can be arranged in the hollow cavity. One or more fans 64 can be set, and each fan 64 is communicatively connected to the monitor 61. The blowing direction of the fan 64 is from bottom to top. Then, the fan 64 blows air upward and cooperates with the heat dissipation ventilation wing guide plate 3 to achieve heat dissipation and moisture removal inside the rectangular housing 1 and inside the cabinet 5.

[0056] One or more temperature and humidity detectors 63 can be arranged in the hollow cavity, and each temperature and humidity detector 63 is communicatively connected to the monitor 61. A water immersion detector 62 can be arranged in the hollow cavity. The lower end of the water immersion detector 62 leads out a detection cable 621 and winds around the outer edge of the bottom surface of the hollow cavity. Then, the detection cable 621 winds around the bottom surface of the hollow cavity at least once to ensure that water immersion detection can be carried out in all directions of the hollow cavity. The specific setting structure is as Figure 5 shown.

[0057] In a more specific embodiment, the busbar 2 is a flexible copper busbar 2. Specifically, each wire in the busbar 2 is composed of a copper wire row conductor, a wrapping layer, an insulating layer, a metal armor layer, and a sheath layer; the wrapping layer is wrapped around the outer wall of the copper wire row conductor, the insulating layer is wrapped around the outer wall of the wrapping layer, and the metal armor layer is wrapped around the outer wall of the insulating layer; the sheath layer is wrapped around the outer wall of the metal armor layer.

[0058] Specifically, as Figure 7 shown, the busbar 2 can be set as a flexible copper busbar 2, and each wire in the busbar 2 relies on a flexible copper wire as a conductor to conduct electricity. Each wire is composed of a copper wire row conductor, a wrapping layer, an insulating layer, a metal armor layer, and a sheath layer, so that each wire meets the insulation and safety usage requirements. The connecting wire row 24 led out by the circuit breaker 23 forms a "T" - shaped connection with the wire in the busbar 2, and the joint of the "T" - shaped connection is strengthened for insulation treatment to prevent the influence on the circuit connection performance when heavy rain or rainstorm backflows. There is a certain gap between the parallel wires in the busbar 2 to improve the safety of using the busbar 2.

[0059] In a more specific embodiment, the cross-sections of the heat dissipation ventilation wing guide plates 3 are all L-shaped, and the heat dissipation ventilation wing guide plates 3 are arranged in a radial pattern with the midpoint of the rectangular housing 1 as the center. Among them, a plurality of installation through holes communicating with the hollow cavity are provided on the lower end surface of the rectangular housing 1, and each installation through hole is equipped with a ventilation and heat dissipation plate 11. A plurality of heat dissipation through holes 111 arranged in a matrix are provided on the ventilation and heat dissipation plate 11; a plurality of ventilation columns 12 communicating with the hollow cavity are provided on the upper end surface of the rectangular housing 1; one end of the ventilation column 12 not connected to the rectangular housing 1 is open towards one side of the rectangular housing 1. Further, a filter plate is provided at the open end of the ventilation column 12 not connected to the rectangular housing 1; filter holes are provided on the filter plate.

[0060] Specifically, it can be set that the cross-sections of the heat dissipation ventilation wing guide plates 3 are all L-shaped. After the heat dissipation ventilation wing guide plates 3 are fixed to the bottom surface of the hollow cavity, a long strip-shaped baffle extends downward. The heat dissipation ventilation wing guide plates 3 are arranged in a radial pattern with the midpoint of the rectangular housing 1 as the center. The specific structure is as Figure 5 shown. The long strip-shaped baffles extending downward from each heat dissipation ventilation wing guide plate 3 are used to guide the airflow so that the heat concentrated in the central area diffuses to the surroundings.

[0061] Further, installation through holes can also be provided on the lower end surface of the rectangular housing 1, and the ventilation and heat dissipation plates 11 are fixedly assembled on the installation through holes. The external shape structure of the ventilation and heat dissipation plates 11 is as Figure 8 shown. A plurality of heat dissipation through holes 111 arranged in a matrix are provided on the ventilation and heat dissipation plates 11. Then, the cold air at the bottom of the rectangular housing 1 can pass through the ventilation and heat dissipation plates 11 and enter the hollow cavity. Driven by the rising of the hot air in the cabinet 5, the airflow moves upward to achieve heat dissipation. Part of the airflow is guided by the heat dissipation ventilation wing guide plates 3 in the hollow cavity and moves outward while moving upward. The specific gas flow direction is as Figure 6 shown. To prevent animals such as mice and cockroaches from climbing into the hollow cavity, the diameter of the heat dissipation through holes 111 can be set to 0.2 - 2 mm; preferably, the diameter of the heat dissipation through holes 111 is set to 0.2 - 1 mm.

[0062] Further, as Figure 6 shown, ventilation columns 12 can be provided on the upper end surface of the rectangular housing 1. The ventilation columns 12 can be arranged on the outside of the cabinet 5. Then, part of the airflow guided by the heat dissipation ventilation wing guide plates 3 and moving outward can be discharged outward through the ventilation columns 12. To enable the ventilation columns 12 to have a waterproof function, the end opening of the ventilation column 12 can be set to face one side of the rectangular housing 1. Further, to prevent animals such as mice and cockroaches from climbing into the hollow cavity, a filter plate can be provided at the end opening of the ventilation column 12, and filter holes are provided on the filter plate. Then, the diameter of the filter holes can be correspondingly set to 0.2 - 2 mm; preferably, the diameter of the filter holes is set to 0.2 - 1 mm.

[0063] In a more specific embodiment, the support 4 includes a vertex support 41 and a transverse support 42; each of the vertex supports 41 is disposed at the vertex of the rectangular housing 1; the transverse support 42 is disposed in the middle of the rectangular housing 1 and is perpendicular to the long side direction of the rectangular housing 1.

[0064] To improve the support effect of the support 4 on the rectangular housing, the support 4 can be configured to be composed of a vertex support 41 and a transverse support 42. As Figure 4 shown, four vertex supports 41 can be respectively fixedly assembled at the four vertices of the rectangular housing 1; at the same time, the transverse support 42 is disposed in the middle of the rectangular housing 1 and is perpendicular to the long side direction of the rectangular housing 1.

[0065] Assembling a cabinet on the integrated power busbar base in the above embodiment constitutes a charging station. The charging station includes a charging gun, a cabinet 5, and an integrated power busbar base; the cabinet 5 is disposed above the rectangular housing 1 and covers the hollow through hole; the electrical components in the cabinet 5 are electrically connected to the circuit breaker 23; the cabinet 5 includes a communication cabinet 5, an energy storage cabinet, a power distribution cabinet, an AC / DC conversion cabinet, and a power stack cabinet; the charging gun is electrically connected to the power distribution cabinet. Among them, heat dissipation holes are provided on the side plate of the cabinet 5; the heat dissipation holes are arranged in a matrix on the side plate of the cabinet 5; an arc-shaped baffle 51 is provided above each of the heat dissipation holes, and the outer edge of the arc-shaped baffle 51 slopes downward.

[0066] A charging station can be constructed based on the above integrated power busbar base. By assembling the cabinet 5 on the integrated power busbar base and assembling the charging gun in the power distribution cabinet and making electrical connections, a charging station with a complete structure can be obtained. Transporting the above charging station to a designated location and connecting it to the mains power can quickly complete the deployment work of the charging station. As Figure 9 shown, to further improve the heat dissipation performance of the charging station, heat dissipation holes can be provided on the side plate of the cabinet 5, and an arc-shaped baffle 51 is provided above each heat dissipation hole, so as to prevent rainwater from entering the interior of the cabinet 5 and improve the waterproof performance.

[0067] The skid-mounted type refers to an integrated structure in which functional components are integrated on a whole base and can be installed and moved as a whole. The production, assembly, and commissioning of the above skid-mounted charging station are all completed in the factory. The cabinet 5 can be installed in the factory, and after electrical connection and commissioning, it can be directly deployed on the charging station site.
