Description

Technical Field

[0001] The utility model relates to a charging pile charging information collection device, belonging to the field of charging piles. Background Art

[0002] With the popularization of new energy vehicles, the number of new energy vehicles has greatly increased. However, especially in big cities, parking spaces are very tight. New energy vehicles need to be charged while parking. However, on the one hand, many owners of fuel vehicles often occupy charging pile parking spaces for convenience. On the other hand, many new energy vehicles do not charge after parking. Thirdly, many new energy vehicles do not drive for a long time after charging. The above situations have aggravated the shortage of charging parking spaces for new energy vehicles. However, there is currently no effective way to manage charging parking spaces. To manage, the first thing to solve is to collect information on whether the cars occupying the charging parking spaces are charged. However, there is currently no special device that can collect information on whether the cars are charged, so in-depth management is impossible.

[0003] The Chinese utility model patent with application number CN202222930334.1 provides a charging pile charging information collection device. A current transformer is installed on the wire used to charge the car. The current transformer detects the current of the wire used to charge the car. The wire used to charge the car is charged by the current transformer, and the working current information of the wire used to charge the car is fed back, so that subsequent parking management can be carried out.

[0004] However, current transformers have the following problems:

[0005] 1. Low accuracy: The measurement accuracy of the current transformer is easily affected by some factors, such as the resistance, frequency, temperature, etc. of the secondary circuit. Therefore, under special circumstances, the accuracy may be reduced, affecting the accuracy of the measurement results.

[0006] 2. Installation posture: The installation position and posture of the current transformer is one of the main factors affecting the measurement accuracy. If the installation position of the current transformer 3 deviates from the center line of the cable, or the cable is not placed horizontally, the distance between the core inside the transformer and the cable is uneven, errors will occur.

[0007] Therefore, it is necessary to improve the installation method of the current transformer and the problems caused by the secondary circuit. Utility Model Content

[0011] Furthermore: the number of the fixing rods is three, and the circumferences thereof are evenly distributed on the cable tie ring.

[0012] Furthermore: the cable tie ring is divided into an upper half ring and a lower half ring, the lower half ring is composed of two symmetrical opening and closing rings, and the opening and closing rings are rotatably arranged on the upper half ring; a mounting plate is arranged at the lower end of the opening and closing ring, and a mounting hole is arranged in the middle of the mounting plate.

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0027] See also Figure 1-3 This is an embodiment of the charging pile charging information collection device of the utility model.

[0028] It includes a charging pile 1, a charging line 2 arranged on the charging pile 1, and a current transformer 3 installed on the charging line 2; the current transformer 3 is installed on the charging line 2 through a posture adjustment device 4; the posture adjustment device 4 includes two symmetrically arranged wire tie rings 5, and a fixing rod 6 is fixed between the wire tie rings 5; the current transformer 3 is fixed between the wire tie rings 5.

[0029] The posture adjustment device 4 of the device can be used to straighten the bent charging cable 2, and then the current transformer 3 can be set on the straightened part of the charging cable 2; such a setting allows the installation position of the current transformer to be on the center line of the cable; when the current transformer 3 is fixed on the charging pile 1, the section of the charging cable 2 is in a horizontal state, so that the distance between the internal core of the current transformer 3 and the charging cable 2 is uniform, reducing the error.

[0030] The function of the cable tie ring 5 of the device is to constrain the charging cable 2 and straighten the charging cable 2. At the same time, the fixing rod 6 is to limit the positional relationship between the two cable tie rings 5 ​​to ensure that the center line of the charging cable 2 coincides with the center line of the current transformer.

[0031] There are three fixing rods 6 , which are evenly distributed on the cable tie ring 5 .

[0032] The three fixing rods 6 can make the positional relationship of the two cable tie rings 5 ​​more stable.

[0033] The cable tie ring 5 is divided into an upper half ring 51 and a lower half ring 52. The lower half ring 52 is composed of two symmetrical opening and closing rings 521, and the opening and closing rings 521 are rotatably arranged on the upper half ring 51. A mounting plate 522 is arranged at the lower end of the opening and closing ring 521, and a mounting hole is arranged in the middle of the mounting plate 522. An upper hinge plate 53 is arranged on the upper half ring 51, and a lower hinge plate 54 is arranged on the opening and closing ring 521. Both the upper hinge plate 53 and the lower hinge plate 54 are provided with hinge holes.

[0034] The cable tie ring 5 of the device is configured in this way mainly to facilitate installation on the charging cable 2; the charging cable 2 can be clamped by utilizing the rotation of the two opening and closing rings 521, and then the opening and closing rings 521 can be completely closed by utilizing the mounting plate 522 and the fastening bolts provided on the mounting holes.

[0035] The fixing rod 6 is in the shape of an elongated strip. A fixing block is welded to the upper end of the current transformer 3 , and the fixing block is fixed on the fixing rod 6 .

[0036] The long strip design makes it easy to install the current transformer 3 on the fixing rod 6 using a fixing block.

[0037] A compensating reactor 7 is also installed on one side of the current transformer 3. For larger load changes, a compensating reactor 7 is installed to perform dynamic compensation to offset the impact of power supply fluctuations.

[0038] The current transformer 3 is electrically connected to a transmission module, and the transmission module is wirelessly connected to the parking management cloud platform.

[0039] The current transformer 3 is arranged on / outside the charging pile 1 .

[0040] When the current transformer 3 is arranged in the charging pile 1, it is connected using a terminal block, and a terminal block is added at the connection point of the secondary line. This can increase the contact area between the secondary wires and reduce the resistance, thereby avoiding the voltage drop problem caused by the wire being too long.

[0041] When the current transformer 3 is fixed outside the charging pile 1 , the connection terminal can also be used.

[0042] However, when the current transformer 3 moves with the cable, the connection terminals are no longer used.

[0043] At the same time, the charging line 2 of this device is relatively short. When charging a car, it is necessary to park the car at a suitable position according to the location of its charging port. This setting is to shorten the length of the access wire and minimize the length of the secondary wiring, thereby reducing the impact of resistance and temperature on current detection.

[0044] For domestic charging piles, if possible, you can consider replacing thicker wires or cables to increase the current carrying capacity, which can directly meet the needs of normal operation of the measurement and protection circuits.

[0045] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
