13A EV chargers

vantech

Hi, 

I started another post regarding portable EV chargers and it raises the question of 13A portable EV chargers and earthing arrangements. 

These devices are readily available on Amazon and from EV dealerships. The user can plug-in and charge at around 2.3kW from a 13A socket. 

These do not take into account the earthing arrangements, nor do they appear to have PEN fault detection in them (unless this isn’t publicised). 

Are they exempt from the regulations because they are “temporary“ and covered by a product standard? 

Appreciate there is guidance on EV charging and outlets destine for this use, however this doesn’t take into account the vast majority of users of these plug them in anywhere they like, for instance when they go on holiday. 

Thoughts?

     The same as touching a metal outdoor tap connected to a PME system, outdoor lighting, heaters, hot tubs on PME. There is risk associated with it all. 

    The difference is, the ESQCR specifically mentions a prohibition for caravans and boats being connected to PME earthing arrangement, and the DTI guidance on the ESQCR says this is because of the safety issue (see Page 20). The issue is perhaps whether you want to stick your neck out and try to differentiate a mobile & transportable unit (717) and a caravan (721 and 708) and an EV on charge (722).
