RE: Power drawn after 100% charge.
On my last two charges one over-ran by 3/4 hour after 100% charge, the other didn't. My latest 16.5Kwh charge finished just within the 7 hour offpeak period working out at 2.3Kwh/hour. I didn't think to step outside and see if the fan was running, maybe it's merely bring the battery back down to cool?
Incidentally I now do two charges, a "dummy" 5 minute one before I go to bed to check the circuit is live, another at off-peak start time. These normally generate two "end of charge" notifications but last time I only got one, the final one. So where did the other go, I saw it charging?
I think we have to accept that these cars are nominally "work in progress", except I don't suppose it is. At least we have something unique! And if they get any cheaper perhaps we can have a spare, just in case......
