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?

I was recently asked to install an external 3-pin socket for a Misubishi PHEV car. The lead that comes with the car, made by Yazaki, is CE marked and has "residual current limit I(delta)n 20mA" on the data plate. I asked Yazaki for details of the device and they replied they were under contract with Mitsubishi not to divulge details of the lead. I asked Mitsubishi UK for details of it and they confirmed there was an RCD in it but did not know any more details, such as type. In the maufacture's handbook for the car (if I downloaded the right one) there is no DOC for the lead, there are some for radio, tyres etc

The property presents as TNS, but as it is in London, and UKPN cannot confirm that the supply cable is not PME (as the majority in London are), it must be treated as PME. The curtilage is not huge around the property and where the car will be parked there is an electric gate within 2 metres.

This would be my first EV charging point and I am a bit stuck as to what to suggest.

It would be good to have a lead that complies with the new 722

Mitsubishi must specify the RCD type required, if they do not, then one has to take worst case scenario and install a B type, you can't even rely on an A type being suitable without data from the vehicle OEM.

Another case of a manufacturer not complying with their responsibilities.

I have lost count of the number of automotive clients I have spoken to that do not know the IEC definition of High Voltage!

They seem to believe that 48 or so volts & above is high voltage!

The automotive industry have created this problem to keep the initial costs of the vehicle to the minimum and pass on the associated costs to the buyer.

With the buying power of that industry, they could easily have designed the vehicles such that the cost increase would have been minimal and the increase in vehicle mass the same, and this would have done away with all of the installation issues we are seeing, but no, profit for them first and foremost.
