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?

    I note that Graham K pointed out that changing the design of electric car chargers in the future to class 2 is essentially impossible.




    In the early days of modern electric mobility (around 2009) car manufacturers refused to limit themself to topologies that prevent DC-faults and now we have to deal with those shortsighted decisions.

    So the infrastructure had to cure that by stipulating a type B RCD or equivalent aproaches.

    But please keep in mind that in those days the automotive industrie was still considered a spearhead of technology.
