Any problems arising from development must be solved with a development perspective and innovative practice. By innovating the operation mode of "mixed ownership", Shenzhen has solved the problem of "one kilometer after Z" in the promotion of new energy public transport, and the measures to realize the pure electrification of exclusive public transport are worthy of reference for the industry. "The charging pile has a large capital investment and rapid technology update. Without the intervention of companies with technical reserves and market power, it would be difficult for enterprises to survive." As one of the top three bus companies in Shenzhen, Yu Gang, the chairman of Shenzhen Bus Group, has a deep understanding of the "charging pile problem" encountered in the promotion of pure electric bus. Yu Gang introduced that the public transport group in a city in China had invested more than 200 million yuan to build 200 charging piles, each charging pile cost about 1 million yuan, 2-3 times the market price. Z could not recover the cost at last, and because it could not keep up with the technology update, many equipment was currently idle.

Miao Wei, minister of the Ministry of Industry and Information Technology, said at the China Electric Vehicle Hundred Talents Forum (2018) that the current vehicle to pile ratio of 3.5:1 across the country still cannot meet consumers' demand for charging. With the continuous growth of the number of new energy vehicles, the problem of insufficient structural supply of charging infrastructure has become increasingly prominent, and the overall scale is still lagging behind. In 2020, China plans to build about 500000 public charging piles. However, compared with the annual production and sales of 2 million vehicles and 5 million vehicles in the 2020 plan, the number of charging piles still does not match, and the vehicle pile ratio even tends to deteriorate. In addition, the layout of charging facilities in China is also not reasonable. The utilization rate of public charging piles is less than 15%. A sustainable business development model has not yet been formed. There is still a two-way contradiction between operating enterprises' profitability difficulties and consumers' high charging prices.

Integrated overview: the fast charging pile (plug) equipment adopts the AC/DC integrated structure. It can realize both DC charging and AC charging. When there are many charging services in the daytime, DC mode is used for fast charging. When there are few users in the charging station at night, AC charging can be used for slow charging. Appearance features: 1. Ergonomic design, taking full account of Chinese characteristics, after installation, the height of the whole machine, the height of the screen, the height of the keyboard, and the height of the charging connector slot are suitable for operation; 2. The form of upper outlet saves half of the operator's physical strength; 3. In consideration of people's usage habits and durability, touch and keyboard are mutually backed up. Touch screen and keyboard are designed to be rain proof and dust-proof; 4. Emergency stop switch with emergency stop; The charging connector placement slot is waterproof; 5m long flexible cable.

In order to popularize the application in any industry, it is essential to continuously reduce the cost. This is especially true for photovoltaic enterprises that are still in the cold winter. Photovoltaic power generation was once very expensive, but driven by economies of scale, the cost of photovoltaic power generation has been declining in recent years, and now it is very close to parity. All this depends on the continuous innovation of photovoltaic technology. Theoretically, a 1 square meter sunlight exposure surface can generate 1000 watts of energy at most. If you want to increase the total reception of existing solar panels, you must focus the light, which will cause the panel to burn out due to excessive temperature.
