EV Charging using 13amp external socket outlet

Former Community Member

For an external socket outlet to be used as a dedicated EV charging point, what are the earthing arrangements ? Given it will be RCD protected. I assuming this socket outlet will be considered as an EV Charging point under the regs.


Is mode 1 not allowed in the UK anymore? I read this in an article done by IET Wiring matter "According to a note in IEC 61851 Mode 1 charging is not permitted in the UK". If so why is it still in the regs?


Thanks.

    Do not think so, as I understand it (second hand though, as no, I'm not paying that much for a copy with only a couple of new paragraphs either) at least for now the current test and the temp rise tests are the same as normal 13A sockets.

     


    I don't agree with this assessment. From the last TWO versions of the standard (BS 1363-2:2016 and BS 1363-2:2016+A1:2018)


    1. The making and breaking tests for "/EV" socket-outlets according to Clauses 17.1.2 (socket-outlet contacts) and 17.1.3 (switches) are performed at a power factor of 0.6 +0, -0.05 lagging (see Clause 17.2). Normally, the loads for the making and breaking tests are non-inductive.


    2. The insertion/extraction under load (15,000 of each) and switch on and off under load (15000 of each) tests of Clause 18, normally carried out with non-inductive load at the socket-outlet rated current, is again performed for "/EV" at a power factor of 0.6 +0, -0.05 lagging.


    3. There is an additional cyclic loading test (Clause 26) for "/EV" socket-outlets, at which the socket-outlet is loaded up to between 13 and 13.4 A, for 28 no. cycles of '8h on'-'1h off'-'8h on'-'7h off'.


    There were no requirements for BS 1363/EV socket-outlets in earlier versions of the standard (BS 1363-2:1995+A4:2012).
