Recently, Hainan Provincial Department of housing and urban rural development (hereinafter referred to as "the Provincial Department of housing and urban rural development") and the provincial fire rescue Corps jointly issued the "technical standard for the construction of electric vehicle charging facilities in Hainan Province" (hereinafter referred to as "the standard"). The standard has been officially implemented since October 1, which is an important guarantee for our province to promote clean energy vehicles, build new energy vehicle pilot areas, and promote the development of electric vehicles. Yesterday, Chen Xiaojing, deputy director of the Provincial Department of housing and urban rural development, interpreted the background, significance, purpose and other aspects of the policy at the policy interpretation conference of the standard

recently, Hainan Provincial Department of housing and urban rural development (hereinafter referred to as "the Provincial Department of housing and urban rural development") and the provincial fire rescue Corps jointly issued the "Hainan provincial technical standard for the construction of electric vehicle charging facilities" (hereinafter referred to as "the standard"). The standard has been officially implemented since October 1, which is an important guarantee for our province to promote clean energy vehicles, build new energy vehicle test areas, and promote the development of electric vehicles compared with other spraying methods. Yesterday, Chen Xiaojing, deputy director of the Provincial Department of housing and urban rural development, interpreted the background, significance, purpose and other aspects of the policy at the policy interpretation conference of the standard

[a goal] by 2030, a total of 940000 charging piles will be built.

it is understood that as early as 2016, the Provincial Department of housing and urban rural development organized relevant units to formulate the "standard for the construction of charging facilities for parking spaces in buildings (Trial)" DBJ, which was issued and implemented on January 1, 2017. On April 29 this year, the general office of the provincial government issued the "Hainan electric vehicle charging infrastructure plan (), which requires a total of 940000 charging piles by 2030, including 166000 public charging piles. In order to adapt to the new situation and development, the Provincial Department of housing and urban rural development, together with the provincial fire rescue corps, launched the revision work. After repeated discussion, modification and enrichment, and the approval of experts, the standard was issued on August 27, 2019 and will be implemented from October 1

Chen Xiaojing introduced that the introduction of the standard will promote the construction of electric vehicle charging infrastructure in our province, improve the quality and safety of electric vehicle charging infrastructure construction projects in our province, and provide a strong guarantee for the development of clean energy vehicles in our province

[b highlights] ensure the reliability of the power load of charging facilities from the design source

compared with the original standard for the construction of charging facilities for parking spaces in buildings (Trial), the revised new standard mainly has three highlights

according to the climate characteristics of high temperature, high humidity, high salt, high radiation, multiple rainstorms and multiple typhoons in Hainan, we should avoid the potential safety hazard locations where charging facilities are prone to failures and accidents at the site selection stage, put forward the requirements for the protection grade and corrosion resistance of equipment enclosures, and refine and expand the requirements for power supply and distribution systems. The value of power load calculation coefficient is adjusted and optimized to ensure the reliability of power load of charging facilities from the design source

moreover, the original completion acceptance chapter is adjusted to "construction and commissioning" and "completion acceptance", and the content of "commissioning" is added to ensure the quality and reliability of the charging facilities put into use

it is clear to minimize the occurrence of power accidents and fires

the new standard expands the fire protection chapter of the original standard, defines the division mode of fire prevention units and parking units and the requirements of corresponding evacuation exits, puts forward the amplification factor of smoke exhaust volume of smoke exhaust fans of fire prevention units, and puts forward corresponding setting requirements for existing buildings with difficult implementation conditions and charging equipment with power greater than 7KW, It not only coordinates with the national standards, but also takes into account the local use characteristics and design habits in Hainan, which is more operational

at the same time, the new standard defines the bottom line requirements for the construction of charging facilities, such as "when the investment scope of underground, semi underground and high-rise vehicles can be equipped with charging facilities in the warehouse, automatic fire alarm system, electrical fire monitoring system, smoke control and smoke exhaust system, fire water supply system, automatic sprinkler system, fire emergency lighting and evacuation indication system should be set up", If these fire prevention measures cannot be taken to accelerate the layout of lithium battery related businesses, there are nearly 40 companies and management measures, so it is not recommended to build charging facilities to minimize the hidden dangers of power accidents and fires

the charging monitoring system is required to control and adjust equipment parameters

in terms of standardized operation, considering the needs of safety and maintenance management, the new standard requires that the charging monitoring system has the ability to control and adjust parameters necessary for charging equipment, driving traditional and high-tech enterprises to fly together, Yangcheng paitangbo (). The specific requirements of data acquisition, monitoring, data processing and storage, event recording, alarm processing, equipment operation management and other functions of the charging monitoring system are detailed one by one. Chen Xiaojing said that the revised new standard is connected with the national standard, and combines the economic development level and regional characteristics of Hainan. It is more suitable for Hainan and can basically meet the needs of technically guiding the construction of charging facilities at this stage
