Its alot quicker on a type 2 charge but still half the speed it could be if we could utilise the full 7.2kw's supplied by most type 2 wall boxes.
The new 18kw battery will take 4-5 hours to charge if its still only fitted with a 3.6kw on-board charger and much longer using the 13a domestic plug charging cable.

Thanks for the additional info, it does seem an oversight to increase the battery capacity but not the charging. I guess it could be due to supply and this is something that may change in the MY23 models. Fitting charging of the battery into a four hour window seems to be the sweet spot and certainly advantageous if on the Octopus Go tariff (4 hours overnight at 5p /kWh)
