BS EN 61851-1-2011 pdf download.Electric vehicle conductive charging system Part 1 : General requirements.
6.3.3 Adaptors
Adaptors shall not be used to connect a vehicle connector to a vehicle inlet.
A conversion adaptor from the socket outlet of the EVSE shall only be used if specifically designated and approved by the vehicle manufacturer or by the EVSE manufacturer. Such adaptors shall be comply with the requirements of this standard, IEC 60884-2-5 and the other relevant Standards governing either the plug or socket-outlet portions of the adaptor. The manufacturer shall clearly indicate the obligation to use adaptors with such a specific designation. Such adaptors shall be marked to Indicate their specific conditions of use, Such adaptors shall not allow transitions from one mode to another. They shall meet the requirements of this standard and IEC 62196-1.
NOTE I Specific mechanical connecting systems can be utilized Instead of cables and plug.
NOTE 2 In some countries the connection between the in-cable control box and the socket outlet may be made by means of a removable adaptor cord of less than 30 cm in length • using non rewireable accessories: JP. FR,
NOTE 3 The use of adaptors from mode I socket oufISts to mode 3 vehicle cable assembly, that maintain the overall safety requirements of this standard Is allowed in the following countries: IT, SE, BE. FR. CH.
NOTE 4 Short cord extension sets, with no mode change, of less than 30 cm In length may be used on the EVSE in the following countries: SE.
6.4 Functions provided in each mode of charging for modes 2, 3, and 4
6.4.1 Modes 2. 3 and 4 functions
These functions shall be provided by the EVSE or the EVSE and vehicle system as given
below:
• verification that the vehicle is properly connected;
• continuous protective earth conductor continuity checking;
• energizatiori of the system;
• de-energization of the system.
NOTE I The pilot functions can be achieved using PWM pilot control as described in Annex A or any other non PWM system that provides the same results. An example is provided In Annex C.
NOTE 2 Specific communication and functions for mode 4 is described in IEC 61851-23.
NOTE 3 Some of these functions may also exist for mode 1 chargng.
6.4.2 OptIonal functions for modes 2, 3 and 4
The following functions should be provided by the EVSE or the EVSE and vehicle system as given below:
The EVSE shall be able to determine that the connector is properly inserted in the vehicle inlet and properly connected to the EVSE.
Vehicle movement by its own propulsion system shall be impossible as long as the vehicle is physically connected to the EVSE as required in ISO 6469-2.
6.4.3.2 Continuous protective earth continuity checking
Equipment earth continuity between the EVSE and the vehicle shall be continuously verified.
6.4.3.3 Energization of the system
Energization of the system shall not be performed until the pilot function between EVSE and EV has been established correctly.
Energization may also be subject to other conditions being fulfilled.
6.4.3.4 De-energization of the system
If the pilot function is interrupted, the power supply to the cable assembly shall be interrupted but the control circuit may remain energized.
6.4.4 DetaIls of optional functions
6.4.4.1 Determination of ventilation requirements during charging
If additional ventilation is required during charging, charging shall only be allowed if such ventilation is provided.
6.4.4.2 Detection/adjustment of the real time available load current of EVSE
Means shall be provided to ensure that the charging rate shall not exceed the real time available load current of the EVSE and its power supply.
NOTE The function of 6,4.4.2 may be required under certain national codes.
6.4.4.3 RetainIng/releasing of the coupler
A mechanical means shall be provided to retain/release the coupler.
6.4.4.4 Selection of charging rate
A manual or automatic means shall be provided to ensure that the charging rate does not exceed the rated capacity of the a.c. supply network (mains), vehicle or battery capabilities.BS EN 61851-1-2011 pdf download.
