BS EN 50620:2017 pdf free.ELECTRIC CABLES – CHARGING CABLES FOR ELECTRIC VEHICLES (BT(DE/NOT)259).
BS EN 50620 specifies design, dimensions and test requirements for halogen-free cables with extruded insulation and sheath having a voltage rating of up to and including 4501750 V for flexible applications under severe condition for the power supply between the electricity supply point or the charging station and the electric vehicle (EV).
The EV charging cable is intended to supply power and if needed communication (details see EN 61851-1 and the EN 62196 series) to an electric vehicle. The charging cables are applicable for charging modes 1-3 of EN 61851-1. The cables in this standard with rated voltage 300/500 V are only permitted for charging mode 1 of EN 61851-1.
The maximum conductor operating temperatures for the cables in this standard is 90 °C. The cables may be:
a) an integral part of the vehicle (case A of EN 61851-1); or
b) a detachable cable assembly with a vehicle connector and AC supply connection to a socket outlet (case B of EN 6185 1-1); or
c) permanently attached to a fixed charging point (case C of EN 61851-1).
BS EN 50620 describes cables whose safeti and reliability is ensured when they are installed and/or used in accordance to the guide to use EN 50565-1 and Annex B.
5 Marking
5.1 Indication of origin
Cables shall be provided with an identification of origin consisting of:
a) either the manufacturers identification thread;
b) or the continuous marking of the manufacturers name or his trademark, or (if legally protected) his identification number, by one of the three following methods:
1) printed tape within the cable:
2) printing, indenting or embossing on the insulation of at least one core. Any core may be chosen;
3) printing, indenting or embossing on the sheath.
5.5 Additional voluntary marking
Additional markings, for example the year of manufacture, are permitted, but are not requirements of this standard. If an additional marking is applied it shall neither conflict nor interfere with the required markings in 5.1 and 5.4. Any additional voluntary marking shall be throughout the length of the cable, and shall be on the external surface of the cable.
Such markings, which are permitted to be applied on the same line as the obligatory marking, or on an additional line, shall be repeated at intervals not exceeding 1100 mm.
