Description

Technical Field

[0001] This utility model relates to the field of charging pile testing equipment, and in particular to a tooling for a non-vehicle-mounted charger virtual load verification device. Background Technology

[0002] Currently, charging pile manufacturers generally use the actual load verification mode for the metrological verification of off-board chargers. Actual load verification mainly consists of an actual load calibrator and a load. As the specifications and power of charging piles continue to increase, manufacturers need to continuously expand the power testing capabilities of off-board chargers, adding corresponding load equipment. Furthermore, actual load verification consumes a large amount of electrical energy; both the equipment investment and electricity consumption represent a significant expense for manufacturers.

[0003] Currently, in addition to the actual load verification mode, there is also a virtual load verification mode. Virtual load verification mainly uses a virtual load verification device to perform metrological verification of off-board chargers. The virtual load verification device mainly consists of a voltage amplifier, a current amplifier, and a standard. Its working principle is to use electronic components to output voltage and current; the voltage and current can be set according to the power specifications of the off-board charger to meet its maximum power requirements. The voltage and current output by the virtual load device pass through the internal metering circuit of the off-board charger to perform metrological verification.

[0004] Therefore, since virtual load testing consumes very little actual electrical energy and the equipment is cheaper than actual load testing, it is the preferred equipment for charging pile manufacturers. However, virtual load testing also has a drawback: it requires corresponding modifications to the charging pile to facilitate the input of voltage and current from the virtual load device. Furthermore, due to the different appearances and internal wiring of off-board chargers, it further leads to connection matching issues between the virtual load testing device and different charging piles. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling for a non-vehicle-mounted charger virtual load verification device that can connect the virtual load verification device and the charging pile without changing the structure of the charging pile, thereby improving the detection efficiency and effect of the charging pile.

[0006] To solve the above-mentioned technical problems, this utility model provides a tooling for a non-vehicle-mounted charger dummy load verification device, including a wiring adapter connected between the dummy load verification device and the charging pile to be tested. One side of the wiring adapter has an input current gun holder and an input voltage holder connected to the dummy load verification device, and the other side has a test charging pile gun port connected to the charging pile to be tested. The side of the wiring adapter with the test charging pile gun port is also provided with a current DC+ port and a current DC- port, so that the dummy load verification device and the charging pile to be tested form a circuit loop through the input current gun holder, the current DC+ port, and the current DC- port.

[0007] Furthermore, the charging station gun port under test includes a first charging station gun port and a second charging station gun port under test, the current DC+ port includes a first current DC+ port and a second current DC+ port, and the current DC- port includes a first current DC- port and a second current DC- port, so that the first charging station gun port, the first current DC+ port, and the first current DC- port are used to connect to the first charging station under test, and the second charging station gun port, the second current DC+ port, and the second current DC- port are used to connect to the second charging station under test.

[0008] Furthermore, the wiring adapter has a test cable header on one side and a first test cable socket and a second test cable socket on the other side, so that the first test cable socket and the second test cable socket are used to connect the first charging pile to be tested and the second charging pile to be tested, respectively, and are connected to the virtual load verification device by the test cable header.

[0009] Furthermore, the wiring adapter is provided with a charging pile working power input socket and a charging pile working power output socket on both sides respectively. The charging pile working power input socket is used to provide working power to the wiring adapter, and the charging pile working power output socket is used to provide working power to the charging pile to be tested.

[0010] Furthermore, the bottom of the wiring adapter is rotatably connected to several rollers.

[0011] Furthermore, the wiring adapter has a handle on its side.

[0012] The beneficial effects of this utility model are as follows: The virtual load verification device inputs voltage and current to the charging pile under test through the wiring adapter. The current at the charging pile under test circulates to the virtual load verification device through the wiring adapter. In this process, the wiring adapter adapts the wiring connection between the virtual load verification device and the charging pile under test, so that there is no need to make adaptation improvements to the charging pile or adjust the wiring of the virtual load verification device for the charging pile under test. The connection between the two can be completed without the need to make adaptation improvements to the charging pile under test. It has the advantages of existing virtual load verification devices and avoids the cost of improving the charging pile under test. Attached Figure Description
