When I bought my MG5 2 years ago I was new to EV ownership. I started to keep a charging record out of curiosity mainly and so that I could monitor roughly how much I was paying in comparison to my previous diesel car. Since then I have kept up with the records and have actually found the exercise quite useful.
I divided the year into 2 halves, October to March and April to September, roughly Winter and Summer. As expected there is a diffence in consumption between the winter and summer months, but not as much as I might have thought. I extrapolate from the charging data to calculate an estimate of range for a total charge, and there is a difference of about 30 miles per charge between the colder and warmer months. My average estimates of total range have been 237(Aug 21 to Mar 22), 246 (Apr 22 to Sept 22), 219 (Oct 22 to Mar23) and 261 (yes 261!!) for Apr 23 to date. I think the latest figure owes much to the good weather we have experienced recently. All these are noticeably more than the WLTP figure of 214 (I have a pre-facelift 5 Excite with the 51kwh battery), and this I attribute to the relatively mild climate we have on the Isle of Wight and that nearly all my driving is done at a fairly leisurely pace around the Island.
I started keeping records in order to get some idea of running cost, and here I think I have done quite well. When I started with the car my previous diesel car was costing about 17p per mile (I was doing about 10 miles to a litre which then cost £1.70. My electric cost for my new car at the time was about 6p per mile. (I don't have solar, or cheap overnight tariffs and I was on a fixed rate 2 year tariff at about 25p per kwh if I remember correctly). Recent comparison would be about 14.5p per mile for my previous diesel (it is now about £1.45 a litre locally) and about 8p per mile for electric, charges here having risen in April (However they have just fallen again). The saving in running an electric car has been substantial over the past 2 years. Taking into account the changes up and down of diesel and electricity prices, I estimate that over the 11000 miles that I have driven I have saved well over £1200 on fuel costs in the 2 years of ownership. I am very satisfied with that!
I know that there are many drivers for whom this record keeping is not appealing, but I have found it quite an interesting exercise.
Happy Motoring to one and all.
