Car Charging Point Maintenance

Hello,  I am looking for some guidance please surrounding Installation and Maintenance of Car charging points,  Both legislative and best practice.
  • Do you mean something like the IET's Code of Practice for Electric Vehicle Charging Equipment Installation – 3rd Edition ?

  • Thank You for the fast response Alasdair,  I will review this now. ?

    If there's anything else you might like to know about EVCE, let me know and I'll see what I can help with
  • Note that the DNOs also have their own conditions, which are  similar to each other but do vary a bit between locations, depending on the make up of the local infrastructure,  and as they can refuse to connect, it is as well to check what rules apply  in each area in advance.
    western power's for example  has a 3.6m spacing requirement from underground metal connected to other earthed systems,for single phase chargers, but not 3 phase ones.

    The customers buried TT earthing system shall be segregated from the WPD buried earthing system (including buried LV metalwork and traditional Paper Insulated Lead Covered cables) by the required distance

    Single Phase or Unbalanced 3 Phase Connection 3.6m

    Balanced Three Phase Connection 0.3m


    6.5 The Electric Vehicle Charging Point (whole installation) shall be segregated (above ground) from metalwork connected to PME or SNE earthing systems by at least 2.5m e.g. metallic street lights and steel frame buildings.





    and does not recommend being adjacent to other supplies.Quite how you achieve all this as well as the recommendations of the COP can become a sore point in crowded town centres.
  • Thanks Mike,


    Excellent information,  you seem to have a grip on this topic.  What I am also interested in is the Maintenance requirements,  withstanding that they will need to form part of any EICR tests carried out is there any outstanding requirements.


    Many thanks in advance

    Don't forget that high charging systems will need fire suppression systems incorporated and components of which also require maintenance

  • Domestic ones however  are little more than an RCD and a microcontroller on a PCB driving a contactor to apply the mains to the care when the it has negotiated a suitable rate of charge, all in a weather proof box.

    I suspect the EICR aspects will be to confirm that the RCD operates OK, and then then much the same as you would for a external air con or any other piece of kit that is out in the rain and vulnerable to mechanical damage.

    To electrically test the EVSE part one may wish to have a lead that plugs in where the car would go to verify the earthing, and the declared current rating to the car are both correct. I'm sure someone makes an expensive adapter to do this already, but as its not my specialty I have yet to see one in the flesh. (though I have seen unofficial designs for a trick circuit that allows you to pretend to be a proper charger of arbitrary capacity.)
