Description

technical field [0001] The invention relates to the technical field of open-source control of charging piles, in particular to a scientific research and testing platform for a V2G charging pile open-source control system. Background technique [0002] Compared with traditional fuel vehicles, electric vehicles have the advantages of saving fossil energy and being relatively friendly to the environment, and the conversion efficiency of electric motors is higher than that of engines; and as battery technology is increasingly optimized, its short capacity can also be reduced. It is gradually being compensated, which makes the batteries on electric vehicles gradually have the characteristics of high capacity. At the same time, the rapid development of power electronic power converters has enabled fast charging and discharging technology to be gradually applied to electric vehicle charging piles, thus enabling battery vehicles to be used as mobile energy storage devices that can b...

Problems solved by technology

[0003] There are several types of existing experimental platforms: 1. In terms of power supply and load, most of the existing platforms use real batteries and connect to the local distribution network. These methods are not conducive to the investigation of environmental factors and the rapid replacement of different batteries for researchers. , and has security risks at the same time; 2. In terms of power converters, most platforms use mature DCAC and DCDC equipment, which firstly requires mature equipment to have bidirectional functions, and secondly, researchers cannot understand its underlying control mechanism, which is very important for upper-level research. The language also has certain limitations, and most of the equipment using open source power converters have the defect of messy wiring harness, which has certain potential safety hazards; 3. On the controller, basically adopt a programming method and experiment based on DSP / FPGA method, which takes a lot of time for researchers to program, and it is often difficult to intuitively find possible problems in the control process, which has the defects of slow development process and unintuitive research, which also makes it difficult for researchers who are just getting started. It is extremely unfavorable for the iteration of scientific research results
