As I understand it, Intelligent Octopus Go can talk directly to certain cars, AND to certain chargers (eg if you have a 7kW wall-box fitted).
So if you have a charger it recognises, the car doesn't matter, but the flip-side is that if you have a car which it recognises, my understanding is the charger doesn't matter. That said I've never used it myself so don't know how well this works out in practice,
There's an eligibility checker here and I believe you can enter the charger type as 3 pin plug or some such.

If you're not on Octopus and wanted to try it, I imagine
@nch45167 will have a referral code which benefits both of you by few quid.
