Appendix P – Guidance for installation and location of electrical vehicle socket-outlets and charging stations (informative)

This Appendix has been included to provide guidance for: (a) circuits intended to supply energy to electric vehicles; and (b) circuits intended for feeding electricity from electric vehicles back into the supply system. This applies to off-board equipment including the vehicle connector for charging electric road vehicles, with a rated supply voltage up to 1000 V a.c. or up to 1500 V d.c. and a rated output voltage up to 1000 V a.c. or up to 1500 V d.c. It refers to IEC 61439 ‘Low-voltage switchgear and control gear assemblies’, IEC 62752 ‘In-cable control and protection device for mode 2 charging of electric road vehicles’, and IEC 62196 ‘Plugs, socket-outlets, vehicle connectors and vehicle inlets – conductive charging of electric vehicles’.
