Problems solved by technology

[0003] In addition, the existing testing equipment for charging facilities has relatively simple functions, can only be manually tested on the spot, the reporting process is complicated, and the work efficiency is low. Performance or communication conformance test function, unable to perform full performance test
[0004] Most of the testing devices or systems in the prior art are mainly based on laboratory testing and are suitable for type testing and testing tasks, but the construction investment is huge, and generally only professional third-party testing agencies choose this solution and undertake testing services externally; There are also more on-site portable testing devices emerging in the world, but they all need to carry power analyzers, oscilloscopes and other instruments at the same time to realize the collection of test data, but the workload of repeated wiring is heavy, and the burden of on-site testing personnel is still heavy. The purpose of light and fast detection work
