Description

Technical Field

[0001] The invention relates to the application field of photovoltaic power generation technology, and in particular to a photovoltaic sunshade structure providing a charging function. Background Art

[0002] On the one hand, with the development of society and the advancement of science and technology, new energy electric vehicles have been popularized in thousands of households and have become one of the main means of transportation for people's daily travel. However, new energy electric vehicle owners generally have charging anxiety, the main reason for which is the difficulty of charging, slow charging and the inconvenience of charging facilities. At present, the charging time of common ordinary fast charging equipment in China is about 40 minutes, while the slow charging takes about 8 hours, which is far from the experience of traditional fuel vehicles that can be refueled in just 5 minutes. This causes users to feel inconvenient when using new energy vehicles, especially when they need to replenish energy quickly. Charging facilities are mainly concentrated in the central areas of districts (counties and cities), while there are fewer in rural and remote areas. This uneven distribution makes it difficult for users to find charging facilities in some areas, especially during the peak charging period on holidays or weekdays. The peak of fast charging overlaps with the peak of electricity consumption, further exacerbating the problem of charging difficulties. In addition, there are problems with inadequate operation and maintenance of charging facilities, such as "charging parking spaces are occupied", "charging facilities are damaged", "interface standards are not unified", and nearly 50% of respondents often encounter charging piles that are damaged or malfunctioning. Although the charging infrastructure network is being built at an accelerated pace, the construction speed of charging facilities cannot keep up with the popularization speed of new energy vehicles, and the structural contradictions of unreasonable layout and uneven distribution of charging facilities remain prominent.

[0003] On the other hand, solar energy is ubiquitous, inexhaustible, clean and pollution-free, and is the most ideal and sustainable renewable energy. Solar cells directly convert light energy into electrical energy, which is an important way to utilize solar energy. Although some technologies have proposed photovoltaic awning products with charging functions, they generally have the problems of large occupied area, complex installation structure and inflexible and inconvenient charging function.
