This International Standard applies to in-cable control and protection devices (IC-CPDs) for mode 2 charging of electric road vehicles, hereafter referred to as IC-CPD including control and safety functions.
This standard applies to portable devices performing simultaneously the functions of detection of the residual current, of comparison of the value of this current with the residual operating value and of opening of the protected circuit when the residual current exceeds this value.
The IC-CPD according to this standard
has a control pilot function controller in accordance with IEC TS 62763;
checks supply conditions and prevents charging in case of supply faults under specified conditions;
may have a switched protective conductor.
These IC-CPDs are intended for use in TN-, and TT-systems.
The use of IC-CPDs in IT systems may be limited.
Residual currents with frequencies different from the rated frequency, d.c. residual currents and specific environmental situation are considered.
This standard is applicable to IC-CPDs performing the safety and control functions as required in IEC 61851-1 for mode 2 charging of electric vehicles.
This standard is applicable to IC-CPDs for single-phase circuits not exceeding 250 V or multi-phase circuits not exceeding 480 V, their maximum rated current being 32 A.
NOTE 1 In Denmark, the following additional requirement applies: for IC-CPDs supplied with a plug for household and similar use the maximum charging current is 8 A, if the charging cycle can exceed 2 h.
NOTE 2 In Finland, the following additional requirement applies: for IC-CPDs supplied with a plug for household and similar use the maximum charging current is 8 A for long lasting charging.
This standard is applicable to IC-CPDs to be used in a.c. circuits only, with preferred values of rated frequency 50 Hz, 60 Hz or 50/60 Hz. IC-CPDs according to this standard are not intended to be used to supply electric energy towards the connected grid.
This standard is applicable to IC-CPDs having a rated residual operating current not exceeding 30 mA and are intended to provide additional protection for the circuit downstream of the IC-CPD in situations where it cannot be guaranteed that the installation is equipped with an RCD with I∆n ≤ 30 mA.
The IC-CPD consists of:
a plug for connection to a socket-outlet in the fixed installation;
one or more subassemblies containing the control and protection features;
a cable between the plug and the subassemblies (optional)
a cable between the subassemblies and the vehicle connector (optional);
a vehicle connector for connection to the electric vehicle.
For plugs for household and similar use the respective requirements of the national standard and specific requirements defined by the national committee of the country where the product is placed on the market apply. If no national requirements exist, IEC 60884-1 may be used. For industrial plugs IEC 60309-2 applies. For specific applications and areas non interchangeable industrial plugs may be used. In this case IEC 60309-1 applies
NOTE 3 In Denmark: the requirements in this standard cannot replace or change any part of the Danish National requirements for plugs for household and similar use according to DS 60884-2-D1.
Plugs, connectors and cables which are part of the IC-CPD are not tested according to this standard. These parts are tested separately according to their specific product standard.
NOTE 4 In the following countries, requirements for EV (mode 2) Cord Sets are covered by NMX-J 677-ANCE-2013/ CSA C22.2 No. 280-13/ UL 2594: Standard for Electric Vehicle Supply Equipment: US, CA, MX.
The switching contacts of the IC-CPD are not required to provide isolation, as isolation can be ensured by disconnecting the plug.
The IC-CPD may have a non-replaceable integral fuse in the phase(s) and/or neutral current path.
