Over 5 charges the figures have varied from 7hrs. 7 mins. to 7hrs. 39mins. while the miles being "replenished" have varied from 64 down to 55.

The latest (sixth) charge has been a surprise. Using the car in a daytime temperature of around +6 the car only achieved 46 miles on a three quarter charge with an estimated 18 miles remaining, giving a low total of just 64 miles. The surprise came with the charge (at a night-time temperature of +4) which completed in a mere 6h 38 mins., an hour less than expected.

My only explanation is that the charge rate is more influenced by mileage gone than by percentage of battery used or by ambient temperature. Does this make sense?
Not sure if it makes sense, but I have been logging my mileage against charge time since I got connected to ZE services. The majority of the time I use the 15A charge. the time is the point at which I get the end of charge notification. Details below if you want to analyse the data

Sorry Paul just noticed you were only looking at charge time to 100%. I have included that info now so you can factor out partial charges
