My wife tried public charge point charging yesterday in Southampton [West Quay].
I spent half an hour trying to work out whether the Ecotricity AC/DC Fast charger would work with an i3. [Using the AC charger]

The i3 isn't on the list of compatible cars & the very helpful man on the advice line said no..... When my wife looked at the unit, it clearly has a mennekes plug - so what's the problem?
Well the ecotricity map's a problem for a start - it has no search facility & describes the unit as 2 sockets 50/43 kW 7 & 10 pin

If you search on http://openchargemap.org/ it describes the 2 connections as "Level 3" 43kW three phase AC Mennekes type 2 and 50kW DC Chademo [which is not the BMW standard].
Whereas NCR http://nationalchargepointregistry.com describes the connections as 43kW three phase AC 500V 120amp IEC 62196-2 type 2 and Chademo.
I trust the engineers not to create a system with a plug/ voltage combination that will damage the car if you plug it in, so I was happy to tell my wife go to IKEA & see if it works..... But she was swayed by the helpline advice & having downloaded the app went to https://www.polarinstant.com/map.php which are the BMW partners & went off to a nearby NCP car park with a "Type 2 socket 7kW" connected up - to the excitement of the attendant who hadn't seen an electric car before.... and it was fine [if expensive].
I am unimpressed. They can't even make it clear what the sockets are, everyone is using different nomenclature and the maps include & exclude various points. I was late for work - but you have to admit it's an original excuse, "I'm sorry guys I was looking for a charge point in Southampton for my wife".
