Abstract: In order to effectively overcome the problems of low tracing efficiency and large tracing error in the traditional DC charging traceability system for charging piles, this paper designs a new DC traceability traceability system for charging piles considering the internet of things and fuzzy clustering. The network is established through ZigBee wireless communication technology. The hardware part of the system mainly includes a wireless communication module, a radio frequency matching module and a communication interface module to solve the problem of low transmission rate of measurement information. The software part uses the fuzzy clustering algorithm to perform real-time frequency division detection on the specified integer harmonics and fundamental current to realise the DC metering source of the charging pile. Simulation experiment results show that the designed system has higher traceability efficiency and lower traceability error, and the highest traceability efficiency can reach 98%.

Keywords: internet of things; fuzzy clustering; DC charging pile; measurement traceability; system design; ZigBee wireless communication technology.
