2 Basic requirement
2.1 Construction
2.1.1 The organizations engaged in the construction of electric vehicle
charging/swap facilities shall have the corresponding qualifications for the
construction of electric power facilities; the construction personnel shall have
corresponding qualifications. The construction and quality management of
charging/swap facilities shall have corresponding technical levels.
2.1.2 The construction organization shall establish and improve the
management system of construction technology, quality, safety production;
formulate various construction management regulations; implement them.
2.1.3 The construction organization shall, according to the contract documents,
design documents and relevant standards and norms, based on the
underground pipelines and other structures (construction) and construction
materials and engineering and hydrogeological data provided by the
construction organization, organize the relevant construction technology
management personnel to make a fact-finding trip to the site to grasp the actual
site conditions, thereby doing well in construction preparation work.
2.1.4 The construction organization shall familiarize with and review the
construction drawings; master the design intent and requirements; implement
self-audit, joint review (disclosure) and sign-off system; propose opinions and
recommendations when finding doubt or error of the construction drawing; if
design change is required, follow the corresponding procedure to apply for
review and sign-for-approval before implementation.
2.1.5 The construction organization shall prepare the construction program
before starting construction. The construction program must be implemented
after approval according to the prescribed procedures. If there is any change,
the change approval shall be handled.
2.1.6 Temporary facilities for construction shall be reasonably arranged
according to the characteristics of the project and have a general layout plan.
For projects that are not suitable for intermittent construction, there shall be
backup power and equipment.
2.1.7 Pipes, cables, members (fittings) and equipment used in the project must
be inspected and properly kept when they are mobilized into the construction
site. During mobilization acceptance, it shall check the order contract, quality
certificate, performance inspection report, instruction manual, commodity
inspection report and certificate of imported products. Follow relevant national
2.2 Completion acceptance
2.2.1 Completion acceptance of charging/swap facilities must comply with the
relevant requirements of electric power construction, acceptance and quality
inspection and evaluation standards and specifications, to ensure stable, safe
and reliable operation of the charging/swap facilities after commissioning.
2.2.2 The model, configuration, quantity, function, performance indicators of all
equipment and other related facilities such as AC charging pile, DC charger,
battery swap equipment, cable, etc. shall meet the requirements of technical
documents such as project contract and liaison meeting minutes, meanwhile
comply with the requirements of the relevant national standards and technical
specifications.
2.2.3 Completion acceptance of charging/swap facilities includes three aspects:
construction quality acceptance, non-energized equipment quality acceptance,
energized equipment operation acceptance.
2.2.4 Before the energized equipment is energized and accepted, the insulation
inspection of each circuit shall be carried out and recorded. The insulation
resistance value shall comply with the design requirements and relevant
standard specifications. When measuring insulation resistance, it shall take
measures to prevent damage to weak electrical equipment and electronic
components. When measuring the electrical insulation resistance value, the
voltage level of the insulation resistance meter used for measurement shall
comply with the relevant provisions of the current national standard GB 50150
Electric equipment installation engineering-standard for hand-over test of
electric equipment.
2.2.5 Before the energized equipment is energized and accepted, the reliability
of the grounding protection line connection of the equipment shall be checked.
The circuit with the residual current protection device shall be tested for
simulated action and recorded.
2.2.6 The items that cannot be tested at the time of completion acceptance may
be inspected via the inspection report as issued by the inspection and testing
institute as approved by the national authority as provided by the manufacturer
or the type test report.
2.2.7 The completion acceptance of electric vehicle charging/swap facilities
shall be carried out on the basis of the self-inspection by the construction
organization and shall meet the following requirements:
1 The construction quality of the project shall comply with the requirements of
this standard and relevant professional acceptance specifications;
3 Power-supply system
3.1 Construction
3.1.1 The power-supply system shall be installed and constructed in
accordance with the design drawings.
3.1.2 The installation of power-supply equipment shall be firm and reliable, with
clear identification and clean inside and outside.
3.1.3 The installation height of similar electrical equipment shall be consistent
when not specified by design.
3.1.4 The laying of cables shall be neatly arranged, firmly bundled, clearly
marked. The length of the terminations shall be left with a suitable margin, there
shall be no such phenomena as twisting, flattening and breakage of the
protective layer. When the cable is connected into the power-supply and the
electrical equipment cabinet, it shall be bundled and fixed; they shall not
generate additional stress to terminal or connector in the cabinet.
