Codeofchina.com is in charge of this English translation. In case of any doubt about the English translation, the Chinese original shall be considered authoritative. This standard is developed in accordance with the rules given in GB/T 1.1-2009. This standard is modified in relation to International Electrotechnical Commission IEC 62752 In-cable Control and Protection Device for Mode 2 Charging of Electric Road Vehicles (IC-CPD) (Edition 1). The following technical changes have been made with respect to IEC 62752: ——Types and dimensions of plugs and socket-outlets shall meet the requirements of GB 2099.1 and GB 1002. ——Types and dimensions of vehicle connectors meet the requirements of national standards GB/T 20234.1 and GB/T 20234.2. ——Terms, types of residual current devices (RCD) adopted and the plugs for industrial use is consistent with those in GB/T 18487.1. ——Notes and types, e.g. classification, requirements and test methods of LLSE, which are applicable to other countries other than China, are deleted. ——Three-phase product type of IC-CPD, e.g. classification, requirements and test methods of LLLNSE, are deleted. This standard was proposed by China Electrical Equipment Industry Association. This standard is under the jurisdiction of National Technical Committee on Low-voltage Apparatus of Standardization Administration of China (SAC/TC 189). This standard is released for the first time. Introduction For mode 2 charging including the situation where it cannot be guaranteed that the installation is equipped with RCDs, for example charging the electric vehicle at an unknown installation, a dedicated protection is used for the connected electric vehicle. This standard describes the relevant requirements for an in-cable control and protection device (IC-CPD) to be used for mode 2 charging, aiming at safely and reliably connecting the electric vehicle to the power supply system. Mode 2 charging for electric vehicle is defined as follows: when the electric vehicle is connected to a.c. network (power supply), plugs and socket-outlets complying with GB 2099.1 and GB 1002 are used on the power supply side; lines, neutrals and earthing protection conductors are used on the power supply side; in-cable control and protection device (IC-CPD) is used for charging connection. For all charging modes, protection against electric shock in case of failure of basic protection and/or fault protection is provided, at least by a type A RCD (see IEC 60364-7-722 and GB/T 18487.1). The IC-CPD is not a protection device for use in fixed installations. In-cable Control and Protective Device for Mode 2 Charging of Electric Road Vehicles (IC-CPD) 1 Scope This standard applies to in-cable control and protection devices 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 shall: ——has a control pilot function controller in accordance with GB/T 18487.1-2015; ——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 GB/T 18487.1-2015 for mode 2 charging of electric vehicles. This standard is applicable to IC-CPDs with single-phase circuits not exceeding 250V and maximum rated current not exceeding 16A. This standard is applicable to IC-CPDs to be used in a.c. circuits only, with preferred values of rated frequency 50Hz, 60Hz or 50/60Hz. 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 30mA and is 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 IΔn≤30mA. 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. GB 2099.1-2008 is applicable to plugs for household and similar use. Power supply plugs, vehicle 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 standards. 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 line(s) and/or neutral current path. 2 Normative References The following documents are indispensable for the application of this document.
