Abstract

The invention provides a bidirectional charging pile. The bidirectional charging pile comprises a first-stage power conversion circuit, a second-stage power conversion circuit, a third-stage power conversion circuit and a control device, through the above structure, the control device can control the third-stage power conversion circuit to be equivalent to the rectifier when a charging instruction is obtained; controlling the second-stage power conversion circuit to perform isolation conversion on the direct current signal obtained by rectification, and controlling the first-stage power conversion circuit to be equivalent to a Buck circuit; and the control device can also control the first-stage power conversion circuit to be equivalent to a Boost circuit, control the second-stage power conversion circuit to perform isolation conversion on the boosted direct current signal and control the third-stage power conversion circuit to be equivalent to an inverter when a discharging instruction is obtained, so that the bidirectional charging and discharging function of the charging pile is realized, and the charging pile is more convenient to use. The charging and discharging requirements of energy storage devices in different voltage ranges are met, and effective utilization of electric energy in the energy storage devices is ensured.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a bidirectional charging pile. Background technique [0002] In recent years, my country has been advocating low-carbon life, and the carbon emissions of automobiles are relatively large. Therefore, my country's automobile industry is also facing the problem of transitioning to low-carbon and environmental protection. With the introduction of the concept of green energy, more and more electric vehicles appear. In the process of trial promotion of electric vehicles, the supporting electric vehicle charging pile is also a necessary equipment. [0003] The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. In case of emergencies such as grid power shortage and power outage, the existing charging piles will not be able to be used. As a kind of distributed power supply equ...
