Yup, the 22kw requires 3 phase electrics and in reality is pretty much a waste of your £500. Wouldn’t say no to it, but wouldn’t pay for it…Its an EU thing, more countries in the EU offer 3 phase as standard at home and France in particular installed a lot of 22kw charging posts due to Renaults obsession with 3 phase charging for their Zoe’s.
The standard car comes with single phase 7.4kw and 11kw on 3 phase (3x 3.6kw).
In life, it's not who you know that's important, it's how your wife found out.
