1 Scope
This Standard specifies the basic principles and technical requirements for the electric
vehicle charging/battery swap infrastructure interconnecting to distribution network.
This Standard is applicable to the electric vehicle charging/battery swap infrastructure
interconnecting to the power grid of 110kV and below.

GB 50053 Code for Design of 20kV & Under Electric Substation
5.3.1 The 220V power supply charging equipment shall be connected to the low-
voltage public distribution box; while the 380V power supply charging equipment shall
be connected to the low-voltage power distribution room through dedicated line.
5.3.2 Access to the charging/battery swap infrastructures of 10(20)kV power grid; for
the capacity less than 4000(8000)kVA, they shall be accessed to the public power grid
10kV line or accessed to ring network cabinet, cable branch box, switch station, etc.;
for the capacity greater than 4000(8000)kVA, the charging/battery swap infrastructures
shall be accessed through dedicated line.
5.3.3 The charging/battery swap infrastructures accessing to 35kV, 110(66)kV power
grid can access to the corresponding buses of the substation and switch station, or T-
connect to the public power grid line.
5.3.4 The schematic diagram of the different voltage level accessed charging/ battery
swap infrastructures to the power grid can refer to Appendix A.
5.4 Power supply distance
After the charging/ battery swap infrastructures access to the power grid, the operating
voltage of their point of common coupling and access point of grid shall meet the
requirements of GB/T 12325; the power supply distance shall be determined through
calculating the power supply load of the charging/ battery swap infrastructures, system
operating voltage, and voltage loss.
5.5 Wiring form
5.5.1 For the charging/ battery swap infrastructures with power supply voltage levels
of 35kV and above, their wiring form shall meet the requirements of GB 50059. For the
charging/ battery swap infrastructures as the secondary important user, the high-
voltage side shall adopt the bridge shape, single bus section or line transformer group
wiring, install two or more main transformers; while the low-voltage side shall adopt
singe bus section wiring.
5.5.2 For the charging/ battery swap infrastructures with power supply voltage levels
of 10(20)kV and below, their wiring form shall meet the requirements of GB 50053. For
the charging/ battery swap infrastructures as secondary important user, the incoming
side shall adopt the single bus section wiring.
5.5.3 The low-voltage side for the power supply transformer of the charging/ battery
swap infrastructures shall have 1 to 2 spare outgoing circuits as needed.
5.6 Power source
5.6.1 The power source point of the charging/ battery swap infrastructures shall have
sufficient power supply capability to provide qualified power quality, and ensure the
checked according to the long-term allowable heat and mechanical strength conditions.
6.4 Cable
The cable laying for the charging/ battery swap infrastructures shall meet the
requirements of GB 50217. The power cable shall not be placed in the same trench as
the heat pipe, pipes transporting flammable, explosive and combustible gases, or liquid
pipes.
7 Reactive Power Compensation
7.1 The reactive power compensation for access the charging/ battery swap
infrastructures to the power grid shall be planned and constructed as per the principles
of “synchronous design, synchronous construction, and synchronous commissioning”.
7.2 The reactive power compensation device of the charging/ battery swap
infrastructures shall be configured in the principles of local balance and easy
adjustment of voltage.
7.3 For the charging/ battery swap infrastructures power supply voltage level of 10kV
and above, its power factor during the peak load period shall be no less than 0.95; for
the charging/ battery swap infrastructures with power supply voltage level of 380V and
below, its power factor during the peak load period shall be no less than 0.9; those that
don’t meet the requirements shall be installed local reactive power compensation
device.
7.4 The reactive power compensation device of the charging/ battery swap
infrastructures shall have the ability to automatically adjust with the switching of the
charging device.
8 Protection and Measurement
8.1 Protection
8.1.1 When the charging/ battery swap infrastructures adopt voltage level of 220V,
380V to access to, the low-voltage switchgear and protection of the distribution line
shall meet the relevant requirements of GB 50054.
8.1.2 When the charging/ battery swap infrastructures adopt voltage level of
10kV~110kV to access to, the protection configuration shall meet the relevant technical
requirements of GB/T 14285.
8.2 Measurement
