At the same time, the province will guide local cities to formulate plans based on districts and counties to further optimize the layout of charging infrastructure to meet the requirements of various types of charging.

(2) Accelerate and improve the construction of the province's charging network layout

As of the end of May 2022, the province has built more than 185,000 public charging piles, and 449 service areas on expressways have built charging stations (DC fast charging stations), effectively meeting the province's demand for electric vehicles to charge and supplement energy in public areas. . The coverage rate of fast charging stations in the expressway service area is 96.2%. Except for some involving the reconstruction and expansion of expressways and objective conditions, the goal of full coverage of charging facilities in expressway service areas in the province is basically achieved. According to statistics, in the past year, the utilization rate of charging facilities in expressway service areas in our province has ranged from 1% to 33%, and the average utilization rate is about 8%, which basically meets the daily charging needs of new energy vehicles on expressways. At the same time, before the holidays, organize the owners of expressway charging piles to conduct a comprehensive physical examination of the charging infrastructure in the service area to ensure that all the piles are in a usable state, and prepare mobile charging vehicles on key expressway sections on major holidays and provide emergency charging services. Explore orderly charging, make the charging piles on the highway more reasonable, and improve the overall charging efficiency of vehicle owners.

2. Improve the technical specifications and standards of charging piles, and strengthen the operation safety and service quality management of charging infrastructure

The country and the province have successively formulated charging technical specifications. At present, the country has issued the "Guidelines for the Safety of Charging Electrical Systems and Equipment" (GB/T 33587-2017), "General Requirements for Electric Vehicle Charging Stations" (GB/T 29781-2013), There are 39 national standards such as "Conductive On-board Charger for Electric Vehicles" (GB/T 40432-2021), and our province has approved the publication of "Design Specifications for Electric Vehicle Energy Storage Charging Stations" (DB44/T 1766-2015), "Electric Vehicles" General Requirements for Site Selection of Charging Stations" (DB44/T 1770-2015), "Code for Marking and Coding of Chargers (Piles)" (DB44/T 1762-2015), "Code for Design, Construction and Acceptance of Electric Vehicle Stereoscopic Charging Stations" (DB44 /T 1754-2015), "Safety Requirements for Electric Vehicle Charging Stations" (DB44/T 1188-2013), "Technical Regulations for Electric Vehicle Charging Infrastructure" (DBJ-T15-150-2018) and other 23 items related to electric vehicle charging facilities local standard. Various types of enterprises are unifying the charging interface. At present, the charging interface has basically realized the common use of all electric vehicles. On the basis of national standards and provincial standards, the power grid company has compiled 13 technical standards including "China Southern Power Grid Co., Ltd. Standardized Design Specification for Electric Vehicle DC Charging Equipment (Trial)". Project equipment is purchased according to unified standards, and projects are purchased according to unified Standard construction, acceptance according to unified standards before operation, to ensure the basic quality of charging stations, and a professional electric vehicle service company has been established to be responsible for the operation, maintenance and operation of charging stations constructed by power grid companies, providing users with safe and stable charging services Guarantee, play an exemplary and leading role for other operators to optimize operation and maintenance work, and actively provide suggestions for improving national standards.

3. Further consolidate the functions of the "Guangdong Easy Charge" platform, and build and improve the big data interconnection platform between charging piles and new energy vehicles

Our commission (provincial energy bureau) entrusted the power grid company to take advantage of its own expertise, customer resources, big data resources, and full network services to build a unified electric vehicle intelligent charging service platform in the province - the "Guangdong Easy Charge" platform.
