Abstract

The invention provides a charging method and system of an AC/DC universal charging pile, the charging pile comprises an AC/DC universal charging socket, an auxiliary power supply module, a detection module, a charging pile management module, an execution module and a charging settlement module, and the charging method comprises the following steps: ST1, enabling the charging pile and charging equipment to be subjected to connection confirmation; ST2, identifying a charging interface and selecting and confirming a charging circuit; ST3, judging whether the state information of the charging equipment is normal or not; ST4, executing the charging program, and monitoring and managing the running state and environment of the charging pile in real time in the charging process; and ST5, after charging is completed, completing charging settlement. According to the charging method of the AC/DC universal charging pile, potential safety hazards caused by misplug are avoided, and the purpose that charging of the charging pile is efficient, stable and safe is greatly achieved through a set detection confirmation program before charging and the step of monitoring the running state and the environment of the charging pile in real time in the charging process.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a charging method and system for an AC and DC universal charging pile. Background technique [0002] At present, there are two charging modes for electric vehicles, one is AC charging mode and the other is DC charging mode. [0003] AC charging has the problems of long charging time and low usage rate of charging equipment. DC charging can greatly improve charging efficiency, but high current charging has a certain impact on battery life. [0004] In response to the above problems, many car companies at home and abroad have proposed to design DC and AC charging interfaces on electric vehicles at the same time, using DC charging to speed up the charging speed, shorten the charging time, and improve the efficiency of charging facilities; use AC charging to meet users' long-term parking and slow charging. demand. Considering that if the AC and DC interfaces are installed on...
