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 outgo......
