Recently sat the 18th Edition Course and of the understanding EV Charging points shall be fed from a TT Supply. PME is acceptable only when feeding any other equipment ie Lamp posts Ticket Machines for example and providing Type A or Type B RCD is fitted and the Charger point is then to be separately spiked. Just looking on the attached and a company called Pod Point suggest TN-S is acceptable with no need for an earth spike. Wondered if anyone else has come across this diagram and can confirm TN-S is acceptable without the spike (see - page 2)
Andy is correct, in practical terms, the IET Code of Practice for EV Charging Equipment Installation recommends all TN-C-S, systems and TN-S systems connected by the DNO (i.e. not private generator or transformer), are considered to be TN-C-S (i.e. PME rules apply) for the purpose of EV charging equipment installation - because either the are already, or might at a future point, become at least partly TN-C-S at some point in the distribution.
