Thanks yes live on edge of West London not that far from Heathrow.
Travel to Birmingham a bit as my son lives there, cannot get to Brum on a single charge. Have used the new bp Giga chargers at the NEC and still only get 38kwh charging speed on Chademo. Cannot try the other port which is Type 2 as faster rapid chargers either have Chademo, CCS or Tesla chargers. Think the type 2 is limited to 42kw anyways. So on face of it 2022 UX 300e will never charge at 50kw. Pointless paying for faster rapid charging when you cannot get it! Better to use a home charger or the mid rapid charger (50kw). Otherwise you are paying over the odds for charging as faster rapid chargers cost more per unit. You probably know that anyway.
On another note have heard many manufacturers now adopting CCS and Tesla as main inputs. Japanese manufacturers generally not doing that. But hopefully Lexus will at least adopt CCS.
