本文提出了一种应用于充电桩现场测试的基于电动汽车的便携式充电桩检测装置。该装置针对现有的充电桩现场测试系统，通过将负载、控制单元、显示屏和计量等融于一体，采用差动保护原理、限流原理等实现对充电桩性能、功能、稳定性、互联互通和计量计费准确性的测试，并直观输出测试结果给测试人员。本装置体积小、重量轻，涵盖了现有充电桩的所有测试项目，可直接替代电动车对充电桩进行全面检测。
This paper presents a portable charging pile detection device based on electric vehicle for field test of charging pile. The device, based on the existing charging pile field test system, combining the load, control unit, display and measurement all together, uses differential protection principle, current limiting principle to achieve the performance of charging pile, stability, interoperability and measurement of billing accuracy of the test, and visual test output to the test results. The device is small, light weight, covering the existing charging pile of all test items, and can directly replace the electric car charging pile to conduct a comprehensive test.
