• 29.060.20 Cables

This standard specifies design, dimensions and test requirements for halogen-free cables with extruded insulation and sheath having a voltage rating of up to and including 450/750 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.

Cables, covered by this standard are understood without exception to be the pure cable component, without any kind of accessories or plugs. They may be

1. an integral part of the vehicle (case A of EN 61851-1); or

2. the cable part of a detachable cable assembly with a vehicle connector and AC supply connection to a socket outlet (case B of EN 61851-1); or
