An engineer friend recently recieved a request to look into the possibility of designing the installation for EV Charging points located on the top floor of a multi storey car park. The building is PME but begs the question of how can the EV Chargers be TT'd correctly ? IMO I would recommended chargers be installed on the ground floor if not only for ease of access (with the possibility of a disabled EV driver indiscrimanately having to park on the top floor) but also the TT spike installation would prove very difficult to install. My advice to him was to rethink the location but again wondered if anyone else had encountered this and how they approached the problem ?
Agreed, top floor of multi-storey, provided of course the top floor is not at ground level, is really "indoor" - depending on how high we are talking, of course, lightning protection may be a more important consideration - installing charging points may well require a re-evaluation of the LPS on the top storey to ensure the charging equipment, and vehicles on charge, are adequately protected by the air termination and rooftop system.
