purpose. This Standard is not applicable to the charging equipment used for the
battery charging system of wheel chairs, indoor electric vehicles, railroad cars, trolley
buses, rail vehicles, industrial trucks (for example. fork lift truck) and vehicles
designed primarily for use off-road. Class II vehicles are not excluded in this Standard.
This Standard specifies basic structure requirements of charging equipment, that is to
say, the aspects covered include characteristics and operating conditions of the
supply device and the connection to the vehicle; technical requirements of charging
equipment and the characteristics to be complied with by the vehicle with these
requirements; requirements on the voltage and current of power supply; functional
requirements for charging mode; requirements for connection and interface of electric
vehicles; and requirements for specific inlet, connector, plug and socket-outlets and
charging cables. This Standard specifies safety requirements for electric shock
protection. This Standard does not cover all safety aspects related to maintenance.

Part 1. Definitions, Test and Procedure Requirements
3 Definitions
This Standard adopts the following definitions.
3.1 Electric vehicle (EV)
Any vehicle propelled by an electric motor drawing current from a rechargeable
storage battery or from other portable energy storage devices, which is manufactured
primarily for use on public streets, roads or highways.
3.1.1 Class I EV
An EV of which the protection against electric shocks, when connected to an a.c.
supply network, does not rely only on the functional insulation, but includes
supplementary safety measures. This shall consist of connecting all exposed
conductive parts to the EV earth terminal.
3.1.2 Class II EV
An EV of which the protection against electric shock does not rely on basic insulation
only; but has additional safety measures such as double insulation. However, it does
not provide protective earthing; or it can be said that the existence of these measures
relies on the specific installation conditions of power station facilities.
3.2 Earth terminal
3.17 Power indicator
Resistor value identifying supply rating recognition by the vehicle.
4 General Rules
The EV shall be connected to the EVSE so that in normal conditions of use the
conductive energy transfer function operates safely. Even if there is some negligence
in normal use, there will be no danger to the person and ambient environment
(especially operating personnel of charging).
In general, this principle is achieved by fulfilling the relevant requirements specified in
this Standard, and compliance is checked by carrying out all relevant tests.
5 Requirements for the Supply Voltage and Current
5.1 Requirements for the supply voltage
The rated value of the vehicle a.c. supply voltage is up to 660 V (see GB 156). The
equipment shall operate correctly within ±10 % of the standard nominal voltage. The
rated value of the frequency is 50 Hz ± 1 %.
5.2 Nominal value of outlet or connector of plug and socket
5.2.1 A.C. nominal voltage is single-phase 250 V, three-phase 415V.
5.2.2 A.C. nominal current is 16 A, 32 A, 60 A, 100, 150 A and 250 A.
6 Charging Mode Functional Requirements
6.1 Four charging modes
6.1.1 Charging mode 1. Connect the EV to the a.c. supply network utilizing
standardized socket-outlets, rated up to 16 A, at the supply side, single-phase or
three-phase. And utilize the phase(s), neutral and protective earth conductors. The
use of charging mode 1 depends on the presence of a residual current device (RCD)
on the supply side. If the presence of an RCD on the supply side is prohibited by
national regulations, charging mode 1 is not permissible.
Note. A standardized socket-outlet is one which meets the requirements of any IEC and/or
national standard.
6.1.2 Charging mode 2. Connect the EV to the a.c. supply network utilizing
standardized socket-outlets, single-phase or three-phase. And utilize the phase(s),
neutral, and protective earth conductors. There is a control pilot conductor between
current. Equipment earth continuity between the EVSE and the vehicle shall be
continuously verified by measuring the current flow on the pilot line.
6.2.1.3 Energization of the system
If the control pilot circuit is established correctly, it shall allow energization of the
system. Energization may also be subject to other conditions being fulfilled.
6.2.1.4 De-energization of the system
If the control pilot circuit is interrupted, the power supply to the cable assembly shall
be interrupted but the control circuit may remain energized.
6.2.1.5 Selection of charging rate
A manual or automatic means shall be provided to ensure that the charging rate shall
not exceed the rated capacity of the a.c. supply network.
6.2.2 Optional functions
6.2.2.1 Determination of ventilation requirements during charging
If additional ventilation is required during charging, charging shall only be allowed if
such ventilation is provided.
6.2.2.2 Detection/adjustment of the real time available load current of the supply
equipment
Means shall be provided to ensure that the charging rate shall not exceed the real
time available load current of the supply equipment.
6.2.2.3 Retaining/releasing of the coupler
A mechanical means shall be provided to retain/release the coupler.
6.2.3 Control pilot circuit
For modes 2, 3 and 4, a control pilot circuit is mandatory. This circuit consists of the
control pilot conductor, the protective earth conductor, EVSE control electronics, and
further electronics on board the EV.
The control pilot circuit shall be capable of performing at least the mandatory
functions described above in 6.2.1.1 to 6.2.1.5. It may also be capable of performing ...
