Description

Technical Field

[0001] This utility model belongs to the field of charging pile testing, specifically relating to a portable charging pile tester. Background Technology

[0002] With increasing global emphasis on air pollution control, new energy vehicles have become a trend. The number of electric vehicles in my country is growing rapidly, leading to a corresponding increase in the scale and number of charging piles / machines. This has also increased the demand for metering and testing related to charging piles / machines. A charging pile tester is an instrument used for on-site testing of the electrical energy error of electric vehicle charging piles / machines. It typically consists of a charging pile interface module, an electrical testing module, and a load interface module. A typical application scenario is as follows: the charging pile interface module connects to the charging gun, and the load interface module connects to the load (such as an electric vehicle). During charging, the electrical testing module of the charging pile tester collects the output electrical energy value of the charging gun in real time and compares it with the data from the electrical energy metering device inside the charging pile to calculate the electrical energy error.

[0003] Conventional charging pile testers typically adopt a box-type structure. In order to facilitate the movement of the instrument box, the box usually needs to be equipped with components such as pull rods and rollers, and a separate dual-head charging cable must be provided to electrically connect the charging pile tester to the load. This makes the overall cost of conventional charging pile testers relatively high.

[0004] Therefore, the industry urgently needs a lighter and more portable charging pile tester. The ideal is that the load interface module of the charging pile tester can be directly connected to the charging socket of the load without the need for an additional dual-head charging cable. This would save costs and reduce the risk of error accumulation and double accidental disconnection caused by connecting both ends of the dual-head charging cable to the socket.

[0008] Furthermore, the clamping device includes a movable locking rod hinged to the housing. One end of the movable locking rod is provided with a pressing part, and the other end is provided with a limiting part for engaging with a slot on the charging socket of the load. The clamping device also includes a spring-loaded component for driving the movable locking rod to position the limiting part in a limited position.

[0009] Furthermore, the outer side of the housing is provided with a pressing part opening, and the end of the housing located at the load interface module is provided with a limiting part opening; the main body of the movable locking rod of the clamping device is disposed inside the housing, and the pressing part extends out of the housing from the pressing part opening, and the limiting part extends out of the housing from the limiting part opening.

[0010] Furthermore, the spring-loaded component is a torsion spring mounted on the hinge shaft of the movable locking rod; or, the spring-loaded component is a spring with one end mounted on the housing, and the other end of the spring abutting against the pressing part.

[0011] Furthermore, it also includes a pressure-controlled switch electrically connected to the electrical test module; the pressure-controlled switch is triggered after the pressing part is pressed.

[0012] Furthermore, the charging pile interface module includes a charging gun socket, a fixing plate I, and a copper rod I arranged sequentially along the direction from the charging pile interface module to the load interface module; the load interface module includes a plug connector, a fixing plate II, and a copper rod II arranged sequentially along the direction from the load interface module to the charging pile interface module.

[0028] As attached Figure 1 -Appendix Figure 4 As shown, this utility model provides a portable charging pile tester, including a charging pile interface module 1, a housing 5, and a load interface module 2 arranged sequentially. Both the charging pile interface module 1 and the load interface module 2 are fixed to the housing 5, forming a compact, integrated structure that ensures the portable charging pile tester is small and easy to carry. The load interface module 2 is configured as the head of a charging gun for a charging pile, while the charging pile interface module 1 is configured as a charging socket for the load.

[0029] The charging pile interface module 1 is used to connect to the charging gun on the charging pile, and the load interface module 2 is used to connect to the charging socket of the load. That is, during the test, the connection between the load interface module 2 and the charging socket of the load fixes the entire portable charging pile tester to the load, ensuring that the portable charging pile tester remains stationary throughout the test and will not be affected by the shaking of the charging gun cable, thus ensuring stability during the test and reducing the possibility of loss of the portable charging pile tester. The load is the device that needs to be charged. For example, the load can be an electric vehicle or a load simulating an electric vehicle. Of course, the load is not limited to this. Any device that can be connected to the charging gun for charging is within the scope of the technical solution protected by this utility model embodiment.

[0030] The charging pile interface module 1 and the load interface module 2 are directly electrically connected inside the housing 5. After the charging pile interface module 1 is connected to the charging gun on the charging pile and the load interface module 2 is connected to the charging socket of the load, the power transmission from the charging gun to the load is realized.

[0031] This portable charging pile tester also includes an electrical test module 3 disposed within the housing 5 and electrically connected to the charging pile interface module 1 and / or the load interface module 2. Exemplarily, the electrical test module 3 can be configured to collect the electrical energy value on the charging pile interface module 1 and / or the load interface module 2 in real time, and then compare it with the data from the power metering device within the charging gun and / or load to calculate the power error. The electrical test module 3 can also be used to monitor current, voltage, and other signals on the charging pile interface module 1 and / or the load interface module 2, and analyze and process the signals to achieve accurate and reliable test data related to the charging pile performance. The specific test items of the electrical test module 3 can be selected by those skilled in the art according to actual needs, and this embodiment of the invention does not limit this. The electrical test module 3 can be structured as a circuit board or integrated circuit. Preferably, the electrical test module 3 is electrically connected to both the charging pile interface module 1 and the load interface module 2.

[0032] The portable charging pile tester provided by this utility model has a simple and compact structure, and can directly connect the load interface module of the charging pile tester to the charging socket of the load without the need for an additional dual-head charging cable for conversion. This makes disassembly, assembly and testing convenient and quick, and can greatly improve the testing efficiency of charging piles.

[0033] In one embodiment, a locking device 4 is provided on the housing 5; the locking device 4 is used to ensure a tight connection between the load interface module 2 and the load's charging socket after the load interface module 2 is plugged into it. The locking device 4 ensures a secure connection between the load interface module 2 of the portable charging pile tester and the load's charging socket, avoiding the risk of accidental disconnection, thereby enabling accurate and reliable testing of the charging pile's performance. It also avoids many problems associated with the additional dual-head charging cable required in existing technologies.

[0034] In one preferred embodiment, the locking device 4 includes a movable locking rod 41 hinged to the housing 5. The movable locking rod 41 and the housing 5 are hinged to form a rocker structure, which can rotate about the hinge axis 45. One end of the movable locking rod 41 is provided with a pressing part 42, and the other end is provided with a limiting part 43 for engaging with a slot on the charging socket of the load. Preferably, the pressing part 42 is an upwardly protruding protrusion for hand-pressing, while the limiting part 43 is a limiting protrusion extending towards the axis of the load interface module 2. When the pressing part 42 moves downward, the limiting part 43 moves away from the axis of the load interface module 2 to release the limiting position; when the pressing part 42 moves upward, the limiting part 43 moves towards the axis of the load interface module 2 to limit the movement.

[0035] The locking device 4 also includes a spring-loaded member 44 for driving the movable locking rod 41 to position the limiting part 43 in the limited position. Therefore, after the load interface module 2 is engaged with the load's charging socket, the limiting part 43 remains locked to the slot on the load's charging socket without external force pressing the pressing part 42. When the load interface module 2 is not engaged with the load's charging socket, the movable locking rod 41 remains fixed in position, preventing it from wobbling. The locking device 4 provided in this embodiment can engage with the slot on the load's charging socket and utilizes the existing structure of the load's charging socket.

[0036] In one embodiment, a pressing opening 51 is provided on the outer side of the housing 5, and a limiting opening 52 is provided at the end of the housing 5 located at the load interface module 2. The main body of the movable locking rod 41 of the clamping device 4 is disposed inside the housing 5, and the pressing part 42 extends out of the housing 5 from the pressing opening 51, while the limiting part 43 extends out of the housing 5 from the limiting opening 52. This arrangement can hide the movable locking rod 41 and the hinge shaft 45, ensuring the aesthetic appearance of the entire portable charging pile tester. At the same time, the housing 5 can also provide physical protection for the movable locking rod 41, the hinge shaft 45, and the spring-loaded part 44, improving their service life and reliability.

[0037] In one embodiment, the spring return element 44 is a torsion spring disposed on the hinge shaft 45 of the movable locking rod 41; in this case, the spring return element 44 does not need to occupy other space, making the internal structure of the housing 5 compact.

[0038] Alternatively, refer to the appendix. Figure 4 The spring-loaded component 44 is a spring with one end set on the electrical test module 3, and the other end of the spring abuts against the pressing part 42; this facilitates the installation of the spring-loaded component 44 and simplifies the assembly difficulty.

[0039] Of course, the structure of the spring-loaded component 44 is not limited to this. Any structure that can achieve the spring-loaded movement of the movable locking rod 41 is within the scope of the technical solution protected by this utility model embodiment.

[0040] In one embodiment, the portable charging pile tester further includes a pressure-controlled switch 6 electrically connected to the electrical testing module 3. The pressure-controlled switch 6 is connected to the electrical testing module 3 and can be configured to control the power supply to and from the electrical testing module 3. The pressure-controlled switch 6 is positioned on the pressing path of the pressing part 42; after the pressing part 42 is pressed, the pressure-controlled switch 6 is triggered. This configuration ensures that when the operator presses the pressing part 42, the outer edge of the pressing part 42 can touch the pressure-controlled switch 6 controlling the electrical testing module 3, thereby avoiding the operational risk of the electrical testing module 3 being prematurely powered on during the insertion of the load interface module 2 of the portable charging pile tester into the charging socket of the load.

[0041] In one embodiment, the charging pile interface module 1 includes a charging gun socket 11, a fixing plate I 12, and a copper rod I 13 arranged sequentially along the direction from the charging pile interface module 1 to the load interface module 2. The charging gun socket 11 is used to cooperate with the head of the charging gun, and the fixing plate I 12 is used to fix the copper rod I 13 in a set position within the charging gun socket 11. The load interface module 2 includes a plug connector 21, a fixing plate II 22, and a copper rod II 23 arranged sequentially along the direction from the load interface module 2 to the charging pile interface module 1. The plug connector 21 is used to cooperate with the charging socket of the load, and the fixing plate II 22 is used to fix the copper rod II 23 in a set position within the plug connector 21. The copper rod I 13 and the copper rod II 23 are fixedly connected to each other to realize the electrical connection between the charging gun socket 11 and the plug connector 21. This configuration allows for high-current transmission, while copper rods I 13 and II 23 also serve as interconnecting components between the charging pile interface module 1 and the load interface module 2, improving the tightness of their connection and significantly enhancing the overall structural stability of the portable charging pile tester. Preferably, multiple sets of copper rods I 13 and II 23 are spaced apart to ensure both electrical transmission stability and structural stability.

[0042] In one embodiment, a protective cover 7 is provided on the outside of the charging gun socket 11. This design prevents dust or moisture from seeping into the charging gun socket 11 and affecting the sensitivity of the interface.

[0043] In one embodiment, copper rod I 13 and copper rod II 23 are fastened together by fasteners, thereby improving the stability of the connection between copper rod I 13 and copper rod II 23. Preferably, each copper rod I 13 and copper rod II 23 is provided with at least two sets of fastening holes. By using bolts and fasteners to fit into each set of fastening holes, the fastening connection between copper rod I 13 and copper rod II 23 is achieved, thereby simplifying the connection while ensuring the stability of the connection.

[0044] In one embodiment, the housing 5 includes a detachably connected upper shell and a lower shell, which are fastened together by fasteners. The upper shell can be further configured as a segmented structure connected by snap-fit ​​or fasteners. This allows the housing 5 to be protectively positioned at the outer end between the charging pile interface module 1 and the load interface module 2 after they are assembled, and includes components such as a clamping device 4, thereby providing a reasonable assembly sequence.

[0045] The specific working principle of this utility model is as follows: When testing a charging pile, the portable charging pile tester can be connected to the charging socket of the load according to the connection method between the charging gun and the socket during the actual charging process. After the clamping device 4 of the portable charging pile tester clamps the load interface module 2 and the charging socket of the load into place, the charging pile to be tested is connected to the portable charging pile tester. After the portable charging pile tester is powered on and passes the communication handshake protocol, the charging pile tester begins to collect voltage, current and other signals during the charging process of the charging pile under test, and analyzes and processes the signals, thereby realizing accurate and reliable testing of the charging pile performance.

[0046] The above description is merely a preferred embodiment of this invention and does not constitute any limitation on the present invention. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solution of the present invention using the disclosed technical content, without departing from the scope of the present invention.
