I did a fairly long trip yesterday afternoon/evening/this morning. I burned through 99% of battery capacity in just over 24 hours, but thanks to a type 2 charger in the car park where I was parked to go to the theatre in the evening, I had an extra 25% to play with.
I was basically pootling. At first an injured shoulder prevented me going as fast as I usually do on my way to Glasgow, and I arrived there with 75% charge after 50 miles. That's where I got my top-up, the type 2 filled the battery to 100% (and didn't charge me, thanks to a fault on the charger!) Late evening I was driving a road I haven't driven much in recent years in the dark, and most of it was cross country.
This morning a ferry crossing to Cumbrae where it's seldom possible to go over about 50, anywhere. I did a bit of scenery-taking-in pootling at pretty low speeds. Back to the mainland in the afternoon, and again slow, because the motorway section of the drive was badly snarled with traffic for some reason. Once in sight of home I wasn't in a hurry and took a detour along some more country roads to pick something up about 12 miles away. I ended with 26% on the battery.
So, a couple of hundred miles of pootling around, lots of slow driving, although I did manage to open it up once or twice. And I had the heating on a bit in the late evening, and then the aircon on most of today.
My car has just finished recharging to 100% and it informs me that its range is 220 miles. So that's what I seem to have to do to get the advertised range on the SR. Probably not going to happen very often, TBH.
