Affected by off-peak electricity consumption, Shenzhen new energy vehicle in operation

On May 19th, due to the impact of the peak power consumption, power stations in some areas of the city experienced power outages. The power outage affected more than 500 charging stations in multiple charging stations, industrial parks and bus terminals. Although the affected charging piles have resumed normal power supply since May 20, according to statistics from the Shenzhen Public Transportation Administration, the number of affected taxis is about 2,700, and the number of drivers is about 4,000. Some pure electric taxis are unable to charge properly, some vehicles are therefore out of service.

The power outage of this peak not only affected the economic benefits of the taxi driver, but also caused inconvenience to the citizens. Shenzhen is actively promoting new energy vehicles, but the construction of infrastructure such as charging piles is far behind the phenomenon of vehicle delivery speed.

In 2015, the General Office of the Municipal Government issued the “Notice on the Work Plan for the Development of New Energy Vehicles in Shenzhen”, proposing to increase the number of applications for pure electric buses, increase the scale of application of pure electric taxis, expand the application range of new energy vehicles, and request the improvement of public transportation planning and construction of charging facilities. Since then, the city has successively introduced new energy vehicles to promote the application of financial support policies to support the development of the new energy vehicle industry. On December 27, 2017, the Shenzhen Municipal Transportation Commission held a press conference to announce that Shenzhen has promoted the application of 16,359 pure electric buses. In addition to retaining 634 non-pure electric vehicles as emergency transportation capacity, the city franchised bus vehicles have all been realized purely electric. It is reported that this is also the first city in the country and even the world's mega-cities to achieve comprehensive and pure electrification of public transportation. By 2020, Shenzhen will also realize 100% electrification of taxis. In addition, according to the "Shenzhen Business Daily" reported on May 24, "Shenzhen Network Appointment Taxi Management Service Management Interim Measures" is being revised, since July 31 all new network vehicles are electrified.

The “blackout” incident exposed the biggest shortcomings of new energy vehicle promotion

Wu Song, general manager of a car company, said in an interview that "the charging facility matching rate is one of the key factors affecting the development of new energy vehicles. It must be planned early and moderately advanced." Although Shenzhen's new energy vehicles have shown rapid growth in recent years, the construction of supporting facilities such as charging piles has not kept pace. The 2017 Shenzhen Parking Survey Report released by the Municipal Development and Reform Commission shows that there are 19,686 charging piles in the city's car parking lot, of which there are 5,204 in Nanshan District, and only 250 in the Guangming New District. In addition, there are currently 18,523 charging piles to be built in the city, and the construction of charging infrastructure needs to be accelerated. It can be foreseen that with the further promotion of new energy vehicles, the problem of insufficient charging piles will become increasingly apparent and become an important factor hindering the promotion of new energy vehicles.

The difficulty in charging new energy vehicles is not only due to the small number of charging piles, but also the low utilization rate of charging piles, the inadequate standard system, unreasonable layout, imperfect supporting services, low participation of car companies, untimely new technology iterations, and higher fees. A series of problems. Therefore, the functional departments cannot only pursue the construction of charging facilities, but also need to incorporate supporting infrastructure into the overall urban planning, introduce detailed rules for the construction of charging facilities, increase the amount and rational layout, and solve the problem of electricity consumption for new energy vehicles from the source; Mobilizing car companies, encouraging social capital to participate in the construction of charging stations, is also conducive to the iterative update of technology and data replacement; Third, in view of the relatively high charging costs of new energy vehicles, it is possible to consider appropriate electricity subsidies for new energy vehicles.

In addition, this incident not only reflects the imperfect construction of new energy vehicle supporting facilities in our city, but also reveals that the relevant functional departments lack linkage thinking in their work and lack effective emergency plans in response to emergencies. The Municipal Power Supply Bureau stated in the statement issued on the 21st recent temperature rises and the power consumption increased sharply. Due to the consideration of reducing the load on the power grid, the power supply bureau has implemented temporary emergency power cuts for some lines according to the actual load gap of the day. The electrical range includes the Merlin off P+R charging station. Although the Municipal Power Supply Bureau has informed the relevant users in advance by means of SMS before taking measures, the power outage of the charging station is still the direct cause of restricted taxi operation. If the power supply department evaluates the possible impacts before the power cut and coordinates and docks with the transportation department, the matter may be effectively avoided. Second, as the temperature rises further, the grid load may further increase. How to effectively cope with the upcoming peak period of high-temperature power consumption, avoid complaints and complaints from the public caused by large-scale power outages, effectively reduce the impact of power outages on economic production, and become an urgent problem for functional departments. Finally, with the promotion of new energy vehicles, the era of comprehensive electricization of automobiles will finally come. How to ensure the power supply of electric vehicles is also worth considering.

A power outage of power grids to alleviate the pressure on the grid caused about 2,700 taxis and 4,000 drivers to be affected by this. Except for objective reasons such as insufficient number of charging piles and unreasonable planning, more exposure of government departments in departmental linkage and emergency insufficient handling.
