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 looking at it as more of a design exercise, if you write down the list of requirements the “EV charging station” with its single pole RCBO with type AC doesn’t tick as many boxes as the new version of the RCD sockets.


    If someone had actually sat down and aligned the various requirements of British Standards and actually considered what uses various electrical equipment is likely to be used for and how things would be used we would not now be trying to establish if and what is suitable for use.


    There is quite a selection of dedicated EV chargers and a multitude of sockets that may be used, but apparently not many of them are suitable for their intended purpose without additional protective measures being taken to ensure they are safe to use.


    Joe Public with a granny lead and a car to charge will just see a socket and use it, whether it be in a house, flat, work place, caravan and camping site or whatever, without seeing any potential risk, particularly in using a socket in an “EV charging station” that is actually labelled as being suitable for electric vehicle charging.


    Something needs to change, starting from the top down.
