Embodiment 1
[0028] refer to figure 1 , a portable easy-to-assemble high-power load module, the load module is used to form charging pile test equipment, the load module includes an integrated box 1, two terminal posts 2 and a resistance module 3;
[0029] In this application, the charging pile testing equipment body is combined with the expanded load module to form the charging pile testing equipment, so as to meet the requirements of the charging pile testing power. The load module adopts miniaturization, light weight, box-type design, integrates components such as high-power resistance module 3 and terminal post 2, and has a reasonable structure. This module has outstanding advantages such as large load current, flexible power adjustment, portability, and wide application. It can meet the diversified detection and test requirements of various charging facilities.
[0030] refer to Figure 2(a) , 2(b) and 2(c), the terminal 2 includes a power line interface board 21, a solid cylinder ...
Embodiment 2
[0040] Embodiment two, the difference with embodiment one is only:
[0041] Further, a handle 11 is provided on the upper end surface of the integrated box body 1 . Since charging piles are distributed in different locations, portability is a very important factor for charging pile test equipment. The integrated box body 1 described in the embodiment of the present application is provided with a handle 11, which is reasonable in structure and convenient for technicians to carry, and enables technicians to carry out testing and testing of charging facilities in different environments and places.
[0042] Further, the front panel, the rear side panel, the left side panel, the right side panel and the bottom panel of the integrated box 1 are all provided with cooling holes 12 . The cooling holes 12 can dissipate heat naturally when working at the rated power or below, so as to prevent the load module from running at an overheated temperature and premature aging.

Abstract
The invention discloses portable high-power load modules easy to assemble. The load modules are used for forming charging pile test equipment. Each of the load modules comprises an integrated box body, two binding posts and a resistance module. The binding posts comprise power line interface plates, solid column bodies and hollow cavity bodies, two metal spring compression sheets are arranged in each of the hollow cavity bodies. The power line interface plates are arranged at the upper ends of the solid column bodies, and the hollow cavity bodies are arranged at the lower ends of the solid column bodies. Screw holes are formed in the power line interface plate. The solid column bodies comprise first solid column body parts and second solid column body parts, and the resistance module is arranged between the two second solid column parts. According to the portable high-power load module easy to assemble, an integrated box design is adopted in the load modules, and the load modules can be connected in series or in parallel to provide test current and power in different gears, so that the charging pile test equipment is convenient to carry and meets the test requirements of differentcharging piles.
Description
technical field [0001] This application relates to charging pile testing, in particular to a portable and easy-to-assemble high-power load module. Background technique [0002] With the vigorous advocacy of the country and the support of relevant policies, the electric vehicle industry has entered a stage of continuous, stable and rapid development, and more and more charging piles have been built and put into use. In order to meet the increasing testing requirements of various charging piles, the mobile charging pile test equipment is developing in the direction of miniaturization, light weight, easy portability, and adapting to diversified testing requirements. Correspondingly, the load module of the test equipment is Higher requirements are put forward in terms of volume, structure and power. At present, the output voltage range of common DC charging piles is generally 200V-750V, and the rated charging power is generally 40kW-120kW. According to the "Code for Inspection...
