EV CHARGING EQUIPMENT

John Peckham
I am hearing from my network of contractors, that have actually read the new 722, that they have been asking charging equipment manufactures for documentary proof to comply with Note 5 of 722.411.4.


They are getting knocked back for asking or in one case a Declaration that says the particular device complies with BS 7671. I think that is wrong to declare that as BS 7671 is an installation safety standard and not a product standard. I believe that as a minimum the equipment must comply with the Low Voltage Directive and be CE marked. I also believe that manufacturers have to issue a Declaration of Conformity. 


BS 7671 722 has numerous references to the various standards required such as BS EN 61851 that the equipment must comply with. I am thinking it may be illegal to offer the sale of equipment that does not comply with the Low Voltage Directive and is not CE marked?


I am hoping the countries top man of equipment safety standards, Paul Skyrme , sees this post and will come on and give us his expert view?


Has any forum member asked for a Declaration of Conformity from EV charging equipment manufacturers and received one?

    If you consider that we have plug-in petrol hybrids, which also have to meet the standard, then, just like with aircraft (even though aviation kerosene is normally only explosive in vapour form) avoidance of static is seen as important, through earthing the fixed electrical ground power, and also providing static discharge for a tending bowser. Earthing is even required for the topologies of Mode 4 rapid chargers that include electrical separation (see Annex K of the 4th Ed of the IET CoP for EV Charging Equipment Installation).


    In addition, there is a requirement to install EV charging in the curtilage of petrol filling stations. Avoidance of static is important there too.



    So not connecting the charge point's c.p.c. to true Earth might not be a good idea?


    Then connecting it to a separated live conductor, floating from Earth - as per Fig A722 in AMD1:2020 - might not be exactly reassuring,
