| 摘要: |
| 针对现有V2G直流充电桩现场检测装置功能不全面、检测方案单一、控制及管理困难等问题，依据国家相关标准，设计了V2G直流充电桩检测方案和检测系统。首先，根据需要设计了3种检测方案：现场检测方案、实验室检测方案以及动力电池检测方案。不同的检测方案对应V2G充电桩不同检测环境和检测项目。然后，依据3种检测方案给出了检测系统的硬件设计和软件设计，能够实现对V2G直流充电桩充放电功能、直流输出性能、并网性能及保护功能等进行检测。同时还可以对电动汽车动力电池状态进行评估，从而判断电池潜在风险。最后，通过对V2G直流充电桩和车辆动力电池进行不同项目检测。测试结果表明所设计的检测方案和检测系统能够准确实现对V2G直流充电桩的功能和性能检测。 |

| Abstract: |
| There are problems of incomplete function, just a single detection scheme and difficult control and management with the existing V2G DC charging pile field detection device. Thus a detection scheme and system for a V2G DC charging pile are designed in line with relevant national standards. First, given the needs, three detection schemes, i.e. field, laboratory and power battery schemes, are designed. Different detection schemes correspond to different environments and items of V2G charging piles. Then, for the three detection schemes, the hardware and software of the detection system are designed. These can detect the charging and discharging function, DC output and grid-connected performance and protection function of the pile. The detection system can also evaluate the state of the power battery of the electric vehicle, and in this way judge the potential risk to the battery. Finally, by testing the V2G DC charging pile and vehicle power battery in different circumstances, the results show that the designed scheme and system can accurately detect the function and performance of a V2G DC charging pile. |
