I hope this works as a picture.


I have no idea why that post would not post

Are you changing to Intelligent Octopus to take advantage of the 7.5p off peak tariff? That would clearly make a huge difference to your running costs. If you apply while you are still using the granny charger, you'll probably get more than just the standard off peak hours at 7.5p - I have a mate who regularly gets over 12 hours @ 7.5p whenever he plugs his tesla in.

I'm unlikely to have a 60mpg diesel so I use the 38mpg I achieved from my 435d for comparison. Over the course of a year my fuel costs are reduced by £2000.

Very odd that I am having this difficulty  posting.
It only seems to be this thread.

I can only guess it might be all the equals and percentage symbols triggering some crude antixss filter.

Not sure if I have understood the above post correctly. Are you saying the car showed 4.89 mpk and 371kWh consumed (that’s very good efficiency btw) but your calculation from the plug suggests 516.25 kWh and 3.52 mpk? So the total non driving losses are 28%? Do you use sentry mode a lot?  

At 29.42 p/kWh your 1815 miles have cost 8.4p/mile. That’s still around a third cheaper than diesel or petrol. If as Nick suggests you get IO then your cost would be 2.1p/mile. 

Thanks for sharing your figures.

Yes.
The car (app) also gives an amount for how much was charged into the car, so it means that charging losses and other non-driving losses were able to be separated.

I do not use sentry mode.

I did a comparison upthread on electricity costs versus fuel costs.  EV seemed similar to a diesel but more expensive to have a petrol:

I used IO for a month, charging the car on the granny charger and was getting those long periods of 7.5p use.  Sometimes 12 hours like your friend.

Then a couple of apps (Octopus Compare and Octo-Aid) both showed Tracker would have been cheaper so I switched to that.

The month on IO averaged out at around 21p per unit for everything (house and car) even with the long off peak periods.  Tracker has averaged around 18p so far.  Not a huge saving, maybe saved £20-£30 or so in the last month, but a lot simpler with Tracker not having to worry about scheduling car/washing machine/dishwasher to run over night.

I’ll stick with Tracker for now until the prices rise and then switch back to IO.  Will hopefully have solar fitted in a few months so won’t need to go back to Tracker in the future.

IO works for me because I have 19.2kWh of battery storage which brings the overall cost of import to around 8p/kWh. Those 6 hours of off peak IO is just enough to fill the battery (90% DOD) from empty in winter.

Nick, with those batteries, if you haven’t done so already it would pay you to move off deemed export and get paid 15p for export. You could even fill your batteries in summer and export at a profit.
