Latest update:

Three charges so far this month so we're doing pretty much a week per charge. I've finally stopped worrying about the range. When the battery reaches about 20%-30% pop it on charge overnight and it's at 80% or so in the morning. Each charge has been a remarkably consistent £3.10.

One issue. Van is boarded out to a very, very high spec with 3/4" ply everywhere. It's affected the payload enough that we can't go out with the full 600 litres (the weighbridge doesn't lie). So we're giving some thought as to whether to suffer tank anxiety or reduce the lining. Not run low enough in water yet to worry but it's an unexpected embuggerance.

Scared the boy the other day when I pulled into a gap in a line of 30mph traffic with a touch of vigour the other day. Great fun to drive.

Is that a 13a charger you're using? 50% charge overnight seems low otherwise?

We remove all unnecessary weight from all our vans, regardless of drivetrain.
With most EV's charging to 80% is best for battery life. If you need more range occasionally then charge to 100%.
If the electricity is only £3.10 assuming about 30p a unit that's only 10Kwh so a 13Amp charger could do that in a bit over 3 hrs. A single phase mains wired charger can do 7.2Kw so in theory it could be charged in about 90mins if the onboard charger will allow that.

It's a 7.4kW charger, so over the five hour cheap rate window (12:30 - 5:30 at 8.5p/kWh on Octopus Go) we're bunging in about 37kWh. Van is 75kWh so almost exactly 50%

It dwarfs all our other energy use...

I think our posts crossed. Five hours at 8.5p per kWh is the charge time.

The routine is now that at roughly 40ish miles range or just above (20% or just above) we bung in 5 hours at 7kW. Takes us to 70 - 80% depending on how close we were to 20 or 30%.
