Good to know. It shouldn't be an issue for much longer - Octopus finally woke up and gave us an appointment to have the smart meter changed next Friday, so as soon as that's done, we can go about getting the electrics changed over to install a charger, etc.
We're going to go and top Sleipnir up at Desford on the rapid charger on Saturday, partly so that we know how to use one (!), and partly because we're going out on Sunday and need rather more charge.
He's down to 24% and 49 miles remaining right now, and will be down to around 10% by the time I get home tomorrow, so we'll take him up to 80% on the rapid charger.
I would have liked to do a slow charge and take him up to 100%, in order to do a balance, but we haven't time for that. Since he's 4 months old, we don't know if the previous owner ever did a balancing charge, so it's on my list to do at the earliest opportunity.
