I can partly answer some of your questions.

- Would someone share their experiences of installing and using a decent 6.6 kW on board charger- Maybe Elcon HK-J series or similar? (If no experience, then a decent opinion will do!)
I don't know if I'd class the newer ultra high frequency, ultra compact Elcon chargers as "decent". One user had a lot of trouble with them, I thought it was @Paulvk
but I can't find the post now. @jonescg
used one in the Prelude conversion, and it seems to work OK, as long as the power source is capable of about 30 A.
- What do I need to know about connecting to the big wide world of Public Chargers? (Do I need to 'talk' with them? Or does it just 'plug in'? )
There is a small amount of "talking" required; you can't "just plug in". There is a small module, the AVC2
, which is designed for doing this "talking" for DIY conversions, but there seem to be problems. See Chris Jones' posts on the Prelude conversion, starting about here
. You might be able to read earlier posts and find the post where he selected the Elcon; I could not quickly find it.
There is little hope of connecting a conversion to a fast (50 kW+) DC charger. The handshaking is very complex, though Damien McGuire was attempting it using used BMW parts. Note that many DC fast chargers won't charge a battery under 200 V, though I believe that the fairly common (at least in Australia at present) Tritium RT 50 kW will charge from 50 V upwards. A 27 kWh battery probably doesn't need DC fast charging, even a higher-end vintage conversion. But the ability to charge at public type 2 "chargers" would be good in a higher-end conversion.
