EV CHARGING EQUIPMENT

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?

  • Ok Richard, we all have a 13A socket with RCD protection. Extra cost zero. Charging point (OK it may be quicker but I could install another larger socket and the bit of electronics to charge quicker for a few quid) I will stick to £500 extra cost. Type Bs and lost neutral detection and a rod and install and everything costs at least that much at present. We are spending a Billion pounds a year (30 years life) no discount rate, so nearer 2 Billion in accounting terms, per life saved. Now explain the logic for this, as I asked, it is not a few extra quid, it is a huge sum much better spent on other things (perhaps even the NHS) where it would make a much bigger difference to lives saved or extended. Cost benefit is never used in safety discussions, so alleged "safety" is never costed.


    Do not get the idea I am against safe working, or reasonable precautions because that is the opposite of my view. The electricity industry do live working all the time and it is more than adequately "safe". There is the odd incident but rarely any deaths to jointers, who are obviously well trained. The saving to everyone in money terms is huge, because cutting off areas from electricity has many downsides, while work is carried out. The same goes for some overhead line repairs where shutoffs tend to be even larger. Now consider the adequate word, how do you assess that? Clearly one has to decide that some accidents are acceptable, at a low level. Realistically it is never zero, as there is no way to do this except by locking everyone up, which also has a risk level (actually quite high). We should do the same with car charging. Every other country accepts a slight risk level, it appears that ours does not. Why not, that is the question we need to answer?
