IEC 62752 Ed. 2.0 b:2024 PDF

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 document 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 document
• provides a control pilot function in accordance with IEC 61851-1:2017, Annex A;
• checks supply conditions and prevents charging in the event of supply faults under specified conditions;
• can have a switched protective conductor.

Residual currents with frequencies different from the rated frequency, DC residual currents and specific environmental situations are considered.

This document 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 document 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.

This document is applicable to IC-CPDs to be used in AC circuits only, with preferred values of rated frequency 50 Hz, 60 Hz or 50/60 Hz. IC-CPDs according to this document are not intended to be used for bidirectional or reverse power transfer, feeding back energy to the system for distribution of electricity.

This document is applicable to IC-CPDs having a rated residual operating current not exceeding 30 mA and which are intended to provide additional protection for the circuit downstream of the IC-CPD as it cannot be guaranteed that the upstream installation is equipped with an RCD rated IΔn ≤ 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 applies. For industrial plugs IEC 60309-2 applies. For specific applications and areas non-interchangeable industrial plugs can be used. In this case IEC 60309-1 applies.

Plugs, connectors and cables which are part of the IC-CPD are tested according to relevant product standards.

The switching contacts of the IC-CPD are not intended to provide an isolation function, as isolation can be ensured by disconnecting the plug.

The IC-CPD is not considered to be a protective device for use in fixed installations.
