Description

Technical Field

[0001] The invention patent relates to the technical field of charging piles, in particular to a charging pile with automatic wire-retracting function and a charging pile management system. Background Art

[0002] Electric vehicles need to be charged through charging piles. Due to the size of the vehicle, the long end of the vehicle body, and the location of the charging interface, public charging piles usually have 3-7 meters of gun wire reserved, and the height of the gun port of the charging pile from the ground is about 1.2-1.4 meters, and the gun wire is mostly wound and hung on the wire take-up device. However, in actual use, most car owners do not extract the gun wires according to the required length on demand, but take them all at once, leaving the gun wires piled up on the ground, posing a safety hazard to other personnel at the charging station; at the same time, due to the implementation of staggered electricity prices, the gun wires piled up on the ground at night are less recognizable and are easily damaged by wheels, shortening their service life; and charging often takes a certain amount of time, and car owners do not pick up their cars on time, or most car owners cannot professionally wind and hang them for storage after picking up their cars. They mostly rely on on-site managers to plug and unplug the charging gun and manually wind the gun wires to the wire take-up device, increasing the workload of on-site managers.

[0003] In response to the above problems, many charging piles use cable reel storage or chute storage, hoping to achieve the functions of pick-up and use and automatic winding, and reduce the workload of on-site management personnel. However, the cable reel storage has the following disadvantages: the gun wire itself is in a heating state when powered on, and the cable reel storage greatly reduces the self-heating efficiency of the gun wire. After the gun wire is curled and wound, the outer insulation skin or the inner core is prone to be damaged, affecting the normal use of the gun wire. After the cable reel is installed, it is inconvenient to inspect and replace the gun wire, which is not conducive to the later management of the operation and maintenance personnel. The chute storage mostly sets the chute on the plane. To meet the needs of the 3-7 meter gun wire, the required installation space is large, the charging station site planning is limited, and the adaptability is low. Summary of the invention

After the authentication is passed, the three-dimensional wire pile authentication module sends a data collection request to the charging pile system. The charging pile system returns the charging pile mark and charging gun status data to the three-dimensional wire pile authentication module based on the request. When the three-dimensional wire pile authentication module receives and identifies the data returned by the charging pile system as a working mark + storage state, it sends a stretching signal to the controller, and the power device drives the slide to slide, increasing the relative height difference with the gun insertion port.

During use, the car owner takes off the charging gun 11, uses the physical authentication card in the sensing area 251, activates the card reader 25, and the card reader 25 sends a signal to the controller through the wireless communication module. The slide 232 is driven by the power device to drive the guide wheel 233 to slide, thereby reducing the relative height difference with the gun insertion port 13. The gun line 12 is in a relaxed state that can be pulled out with the pulling force. After charging is completed, the car owner puts back the charging gun 11.

8. The charging pile with automatic wire collection function according to claim 1, characterized in that: The outer surface of the three-dimensional wire pile is also provided with an LED light for illuminating and guiding the card reader, and the card reader also includes a display screen and an input panel.

9. A charging pile management system, applicable to a charging pile with an automatic wire collection function as claimed in any one of claims 1 to 8, characterized in that: Including communication interconnected charging pile system, three-dimensional line pile system and management cloud platform; The charging pile system includes a charging pile authentication module and a charging gun acquisition module. The charging pile authentication module pre-stores the local charging pile number and assigns a working / fault mark to the charging pile by collecting the real-time working data of the charging pile. The charging gun acquisition module is used to collect the real-time power-on / power-off / storage status of the charging gun, and generates charging gun status data with a timestamp based on the collection results. The three-dimensional charging pile system includes a physical authentication card, a three-dimensional charging pile binding module, and a three-dimensional charging pile authentication module. The three-dimensional charging pile binding module and the three-dimensional charging pile authentication module are fixedly installed in the card reader. The physical authentication card is pre-written with the local charging pile number. The three-dimensional charging pile binding module reads the pre-written charging pile number through the card reader, binds the reading result with the pre-stored local three-dimensional charging pile number, and overwrites the matching result into the physical authentication card to complete the binding operation of the three-dimensional charging pile and the charging pile. The three-dimensional charging pile authentication module also pre-stores the three-dimensional charging pile number of the machine, which is used to identify the read and write data in the physical authentication card, make data requests to the charging pile system, receive and identify the data returned by the charging pile system, and send stretching / reset signals to the controller; The management cloud platform is used to store and manage the local charging pile number set, local stereoscopic line pile number set, matching result set, charging gun status data, and charging pile tag data uploaded to the cloud; The method of using the charging pile management system includes the following steps: The car owner receives the physical authentication card with the binding operation completed from the on-site manager, removes the charging gun from the gun insertion port, and aligns the physical authentication card with the sensing area for identification; The three-dimensional line pile authentication module identifies whether the read and write data in the physical authentication card is consistent with the pre-stored three-dimensional line pile number. After the authentication is passed, the three-dimensional line pile authentication module sends a data collection request to the charging pile system. The charging pile system returns the charging pile mark and charging gun status data to the three-dimensional line pile authentication module according to the request. When the three-dimensional line pile authentication module receives and identifies the data returned by the charging pile system as a working mark + power-off state, it sends a reset signal to the controller, and the power device drives the slide to slide to reduce the relative height difference with the gun insertion port; After charging is completed, pull out the charging gun and identify the physical authentication card again. The three-dimensional wire pile authentication module identifies whether the read and write data in the physical authentication card is consistent with the pre-stored three-dimensional wire pile number. After the authentication is passed, the three-dimensional wire pile authentication module sends a data collection request to the charging pile system. The charging pile system returns the charging pile mark and charging gun status data to the three-dimensional wire pile authentication module based on the request. When the three-dimensional wire pile authentication module receives and identifies the data returned by the charging pile system as a working mark + storage state, it sends a stretching signal to the controller, and the power device drives the slide to slide, increasing the relative height difference with the gun insertion port.

10. A charging pile management system according to claim 9, characterized in that: The charging pile system also includes a charging pile monitoring and alarm module, which is used to send a fault repair signal to the local manager and remote assistance personnel through the management cloud platform when a fault mark appears on the charging pile; when the power-off state of the charging gun exceeds the preset warning value, an assistance return signal is sent to the local manager through the management cloud platform.
