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 was not disputing the present situation Paul, I was suggesting that we could change if we wanted. As we are under no obligation to implement EU directives in future, that should be open to consideration. Considering some of the proposed ideas we have had put forward (the <1kW kettle and the extra low power toaster) a considerable degree of caution is required as to the usefulness of existing standards in the EU, and remember as US trade will probably increase those standards we do use may move more towards the US ones. We are not tied to Europe in any realistic way soon, and need to make the most of this.


    I see no reason at all Graham why a BS1363 plug on an appliance should cost between £2 and £10 extra over a euro one. It is a slight difference but then so is making a product for other international markets as well as Europe. To any reasonably flexible manufacturer the cost should be essentially zero. We are not making one offs here, imagine cars where slight differences exist between every one off the line (trim, colour, engine size, entertainment etc), how to they manage? £10 to a car manufacturer is a fortune to loose to keep a particular market.
