In-cable control and protection device for mode 2 charging
of electric road vehicles (IC-CPD)
1 Scope
This document 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 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
- has a control pilot function controller in accordance with GB/T 18487.1-2015,
Annex A;
- 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 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 document is applicable to IC-CPDs performing the safety and control functions as
required in GB/T 18487.1 for mode 2 charging of electric vehicles.
This document is applicable to IC-CPDs for single-phase circuits not exceeding 250 V,
their maximum rated current not exceeding 16 A.
This document 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
document are not intended to be used to supply electric energy towards the connected
grid.
This document 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 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 GB/T 2099.1-2021 apply. Types, basic
parameters and dimensions are in accordance with GB/T 1002.
Plugs, connectors and cables which are part of the IC-CPD are not tested according to
this document. These parts are tested separately according to their specific product
standard.
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.
The IC-CPD is not considered to be a protective device for use in fixed installations.
