NB/T 42077-2016In-cable Control and Protective Device for Mode 2 Charging of Electric Road Vehicles (IC-CPD) (English PDF)

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 Ideltan<=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.
