3 Definitions
Clause 3 of part 1 applies. Additional definitions relating to this part of the standard are under consideration.
4 General requirements
The connection of electric vehicles can be made by one or more of the methods described in part 1. The a.c. electric vehicle charging station may have one or more socket-outlets/vehicle connectors.
The ac, electric vehicle charging station shall be connected to the electric vehicle so that in normal conditions ot use the equipment operates to reduce the risk of fire, electric shock or injury to persons, either indoors or outdoors.
In general, this Is achieved by fulfilling the relevant requirements specified in this standard and compliance is checked by carrying out all relevant tests. General requirements for the a.c. electric vehicle charging station can also be found in IEC 60439-1 –
5 Standard conditions for operation in service and for Installation
The rated value of the ac. supply voltage is up to 690 V. The equipment shall operate correctly wIthin ±10 % of the standard nominal voltage (see IEC 60038) The rated value of the frequency is 50 Hz ± 1 % or 60 Hz ± 1 %.
The ambient temperature range during charging may be between —30 °C and +50 C and at a relative humidity of between 5 % and 95 %.
NOTE Nat.onal codes and regulahona may require difleent oVeatlng temperature ranges.
6 RatIng of the ac. Input and output
The input voltage and current rating is according to IEC 60038.
The output voltage and current rating shall not exceed the values given in table 1. Lower current values may be used.
7 General test requirements
7.1 All tests in this standard are type tests.
7.2 Unless otherwise specified, type tests shall be carried out on a Single specimen as delivered and configured in accordance with the manufacturer’s instructions.
7.3 The tests in 11.3 may be conducted on separate samples at the discretion of the manufacturer. Unless otherwise specified, all other tests shall be carried out in the order of the clauses and subclauses in this part.
7.4 The tests shall be carried out with the specimen, or any movable part of It. placed in the most unfavourable position which may occur In normal use.
7.5 Unless otherwise specified, the tests shall be carried out In a draught-free location and at an ambient temperature of 20 °C ± 5 C.
7.6 The characteristics of the test voltages in 10.1 shall comply with IEC 611 80-1.
8 FunctIonal and constructional requirements
8.1 Control functions
For mode 3 charging. the a.c. electric vehicle charging station provides part of the control functions listed in 8.4 of part 1 of this standard.
8.2 Emergency service
If required by national rules, an emergency disconnection device shall be Installed to isolate the ac. supply network (mainst from the a.c. electric vehicle charging station in case of risk of electric shock, fire or explosion. The disconnection device shall be provided with a means to prevent accidental operation.
8.3 Permissible surface temperature
The maximum permissible surface temperature of parts of the a.c. electric vehicle charging station which are hand grasped, at the maximum rated current and at an ambient temperature of 40 °C. shall be
— 50 C for metal parts;
— 60 C for non-metallic parts.
For parts which may be touched but not grasped, maximum permissible surface temperature
under the same conditions shall be
一60。C for metal parts;
85。C ftor non-metalic parts.
NOTE National codes may alow other temperatures.
8.4
Charging station protection degree (IP)
The a.c. electric vehicle charging station, when energized or not, and with the socket-outlet
access trap door, if any, closed, shall provide a minimum degree of protection of IP44.
Compliance is checked by test in accordance with IEC 60529.
8.5
Storage means for the cable assembly
For case C connections, a storage means shall be provided for the cable assembly and vehicle
connector when not in use. The a.c. electric vehicle charging station should be provided with a
means to indicate whether or not the cable assembly/vehicle connector has been stored as
intended after disconnection from the vehicle.
