Guangzhou, January 28 (Reporter Guo Jun) On January 28, the first "photovoltaic + carport" power generation project built at Guangzhou Baiyun International Airport was officially put into operation in the P6 parking lot. It can serve 158 vehicles charging at the same time, and is the largest public fast charging station in Guangzhou.

As the first "photovoltaic + carport" power generation demonstration base of Baiyun International Airport, P6 charging station installs photovoltaic panels above the shading carport, which can not only ensure the shading and rainproof effect of the vehicle, but also achieve the best power generation effect. According to the relevant person in charge, the charging station can not only charge the car, but also technically realize the interaction of the car network, and the new energy vehicles that come here to charge can be charged through the V2G charging pile, charging and storing energy when the power grid load is low, and when the power grid load is high, the power battery on the car can be sent to the power grid in reverse, reducing the charging cost. The entire charging station has formed an intelligent charging network, which can realize real-time monitoring of voltage, current, temperature and other operating data, and create a new power system with new energy as the main body.

P6 charging station to achieve new energy vehicle charging new energy, the project adopts the photovoltaic power generation strategy of spontaneous self-use, surplus electricity on the Internet, from the direct current emitted by photovoltaic to alternating current, transmitted to the box change of the charging pile, from the box to the charging pile to supply stable power, support the fast charging mode with a maximum power of 180kw, and give priority to the use of zero carbon emission photovoltaic systems to charge the vehicle. The total installed capacity of the photovoltaic carport is 289kW, laying 636 pieces of the current mainstream 450 Wp photovoltaic modules in the industry, the power generation of the photovoltaic carport is directly used as a supplementary electricity for the charging pile, it is expected to serve 350,000 vehicle charges per year, the charging capacity is expected to be 8.4 million kWh, of which the theoretical power generation capacity of photovoltaic power generation is 340,000 kWh / year, which is equivalent to saving about 118.56 tons of standard coal per year, and it is expected to reduce carbon dioxide emissions by about 308.33 tons and sulfur dioxide by about 2.85 tons per year. Nitrogen oxides are about 0.83 tons, in addition, dust and soot, cinder can be reduced by about 30.83 tons.

The charging equipment of the P6 charging station adds two layers of "equipment + data" safety protection technology, covering the vehicle side and charging side in an all-round way, which can diagnose and detect 12 potential battery safety hazards in real time, comprehensively review the battery height, temperature difference, temperature rise, voltage difference, internal resistance, capacity, consistency, leakage current, etc., accurately warn of battery failure, and deeply detect the "health status" of the vehicle. The scene is also equipped with a camera with firework detection function, and the entire charging process can be monitored, warned, controlled and traced to the safety hazards of the car.

The owner scans the two-dimensional code on the charging terminal to realize one-click charging and one-key payment, which is convenient and fast. When the owner leaves the vehicle for check-in and picks up relatives and friends to take the plane, he can still remotely understand the current power, mileage, time and charging situation of the car in real time.

In order to facilitate passenger operation, Baiyun Airport has added supporting signage, charging process guidelines, lounges and restrooms and other infrastructure at the site. Car owners can search for the destination Baiyun Airport through the special call mobile app and quickly locate to the P6 parking lot charging station. Through the special caller mobile app, you can understand the use of real-time charging pile terminals, and support a variety of charging methods such as intelligent charging, scheduled charging, scheduled charging, APP charging, and car charge recognition.
