Abstract
Description
Technical Field
[0001] This utility model relates to a line connector for collecting charging current and voltage data of new energy vehicles, belonging to the field of electric vehicle testing technology. Background Technology
[0002] Measuring the charging capacity of new energy vehicles is an important part of new energy vehicle testing.
[0003] National standard GB / T18386.1-2021, clause 6.3.4.1, requires that "when charging via AC, the power measuring device should be installed between the vehicle plug and the power supply equipment"; GB / T18386.2-2022, clause 5.6.2, requires that "if the vehicle is equipped with an on-board charger, the power measuring device should be installed between the on-board charger and the power supply equipment," meaning that current and voltage probes need to be installed on the charging cable. The traditional method involves stripping the outer protective material and shielding layer of the charging cable to extract the individual wires for probe installation. However, this poses safety hazards, is susceptible to electromagnetic interference, is unsuitable for laboratory testing, and is extremely time-consuming and labor-intensive in practice. Utility Model Content
[0004] The technical problem this invention aims to solve is: how to conveniently, safely, and accurately collect data on the current and voltage of the charging line when charging a new energy electric vehicle at a charging station.
[0005] To address the above problems, the technical solution proposed by this utility model is as follows:
[0006] A line connector for collecting charging current and voltage data of new energy vehicles includes a base body, on which a power inlet for plugging in a charging gun is provided, a power output cable and its charging gun, copper busbars for current sensing detection corresponding to each neutral and phase wire, and connectors for voltage detection corresponding to each neutral and phase wire. The power inlet, copper busbars and connectors are located on the front of the base body.
[0007] The copper busbar includes an N copper busbar corresponding to the neutral wire, and L1, L2, and L3 copper busbars corresponding to the three phase wires. The connector includes an N connector corresponding to the neutral wire, and L1, L2, and L3 connectors corresponding to the three phase wires.
[0008] The copper busbar includes an N copper busbar corresponding to the neutral wire and an L1 copper busbar corresponding to a phase wire. The connector includes an N connector corresponding to the neutral wire and an L1 connector corresponding to the phase wire.
[0009] All the connectors are located in a recessed socket on the front of the base, and are equipped with a protective cover that can be closed and opened.
[0010] The power output cable is located on the side of the base.
[0011] The power inlet is also equipped with a protective cover that can be closed and opened.
[0012] The front of the seat is also equipped with an air switch and a protective cover that can be closed and opened.
[0013] The top of the seat is also equipped with a handle.
[0014] The bottom of the base is also provided with a hook for hanging the charging gun and its cable.
[0015] A main protective door is provided on one side of the seat to cover the front of the seat. Beneficial effects
[0016] Unlike traditional methods that require breaking the charging cable to collect current and voltage data, this method simply requires plugging one charging gun into the connector and the other into the electric vehicle to collect data directly from the line connector. It is safe, convenient, and the data obtained is more accurate. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments and accompanying drawings: Example 1
[0022] like Figure 1As shown, a line connector for collecting charging current and voltage data of new energy vehicles includes a connector body 1. The connector body 1 is provided with a power inlet 2 for inserting a charging gun 9, a power output cable 8 and its charging gun 10, copper busbars 3 for current sensing detection corresponding to each neutral and phase wire, and connectors 4 for voltage detection corresponding to each neutral and phase wire. The power inlet 2, copper busbars 3 and connectors 4 are located on the front of the connector body 1. The charging gun 9 is connected to the power supply of the charging pile or household power supply via a cable. Originally, it was directly plugged into the charging inlet of the electric vehicle to be charged. In this application, the charging gun 9 is plugged into the power inlet 2 of the connector, and then the power output cable 8 on the connector body 1 transmits the current to the charging gun 10. The charging gun 10 is plugged into the charging inlet of the electric vehicle to be charged. This radial charging of the electric vehicle forces the charging current to flow through the line connector, thereby realizing the collection of current and voltage data at the line connector. The copper busbar 3 is used to detect the current intensity of the charging current by induction, and the connector 4 is directly plugged into a voltmeter to detect the voltage of the charging current. This eliminates the need to break the insulation of the charging cable and connect the neutral and phase wires to collect current and voltage data, making data acquisition both safe and convenient. Furthermore, because it is virtually unaffected by complex electromagnetic interference, the inductive detection of the current is more accurate.
[0023] The copper busbar 3 includes an N copper busbar 300 corresponding to the neutral wire, and L1 copper busbars 301, L2 copper busbars 302, and L3 copper busbars 303 corresponding to the three phase wires. The connector 4 includes an N connector 400 corresponding to the neutral wire, and L1 connectors 401, L2 connectors 402, and L3 connectors 403 corresponding to the three phase wires, thereby enabling power supply voltage detection for the three-phase charging cable. Of course, current and voltage detection can also be performed on a single-phase cable by discarding the already installed L2 copper busbars 302 and L3 copper busbars 303, and L2 and L3 connectors 402 and 403.
[0024] All the connectors 4 are located in a socket cavity 6 on the front of the base body 1, and are provided with a protective cover 601 that can be closed and opened.
[0025] The power output cable 8 is located on the side of the base 1 to avoid interference from the power output cable 8 when current sensing is performed and when the voltage plug is plugged in.
[0026] The power inlet 2 is also equipped with a protective cover 201 that can be closed and opened.
[0027] The front of the base 1 is also provided with an air switch 5 as a protective device, and a protective cover 3 501 that can be closed and opened.
[0028] A handle 7 for moving is also provided on the top of the base 1.
[0029] At the bottom of the base 1, there is also a hook for hanging the charging gun 9 and its cable. Example 2
[0030] like Figure 2 As shown, the difference between this embodiment and the first embodiment is that a main protective door 101 is provided on one side of the seat body 1, which can cover the front of the seat body. Example 3
[0031] like Figure 3 As shown, the difference between this embodiment and the first embodiment is that the copper busbar 3 includes an N copper busbar 300 corresponding to the neutral wire and an L1 copper busbar 301 corresponding to a phase wire, and the plug interface 4 includes an N plug interface 400 corresponding to the neutral wire and an L1 plug interface 401 corresponding to the phase wire, which are specifically used to perform power supply voltage detection on the single-phase charging cable.
[0032] The above embodiments are only used to describe the present invention more clearly, and should not be regarded as limiting the scope of protection covered by the present invention. Any equivalent modifications should be regarded as falling within the scope of protection covered by the present invention.
