Help needed-Charging socket type

You need to be absolutely sure that's a car charging port for starters as there are some industrial sockets that are very similar - your instruction manual advises the use of the supplied charger as much as possible rather than a charging station (which might be what your socket effectively is & appears to need an additional cable the manual calls Mode 3)

 

I can quote your owners manual with comfort but I am uncomfortable speculating on a cable that the manual implies your dealer should have details of for a half million dollar car with a fussy electrical system !

What you may find on Amazon is a converter/transformer to reduce the building socket power to the correct UK style 3 pin socket for your supplied charger - your building's electricians may even have a suggestion - try asking what do they do to be able to use a non-rechargeable 240VAC drill or similar in your garage ?

 

Looking into it further it may be that the electricians use a special cable something like this so check with them https://www.desertcart.com.kw/products/512229136-hdiuk-phase-1-400-v-3-phase-cee-plug-to-240-v-l-1-fly-lead-converter-red-32-a-400-v-plug-to-heavy-duty-twin-13-a-sockets

 

Be sure to also check with the your building's people if its the sort of thing they use too to get a type G socket
