Charging history for non-Tesla chargers

[Shadar]

Hi guys, this is probably a stupid question but I cannot find an answer..

Is there a way to see Tesla's charging history or at least stats on the last charge? I noticed today during charging that PodPoint station was claiming 38kWh added to the battery while Tesla was claiming 32kWh. Want to re-check the stats but it seems to be impossible to do so. Is there a secret menu option?

Charging isn’t always 100% efficient, especially when the battery is cold.
It is possible you used 38kW but were only able to add 32kW to the battery.

I personally use TeslaFi.com Tesla Model S 3 X Y Data Logger for keeping track of all charges, I rarely see 100% efficiency unless using SuperChargers - the car pre-heats the battery on the way for optimum charging.

I think there is an "overhead" being shown here. It is reported on other threads. There may be a slightly smaller amount getting into the battery because of heat/conversion loss etc.

Podpoint app should show you what you put in. Apps like Teslamate and Teslafi will log all of this for you.

Edit: How cold was the temperature today? Was the battery cold too? Were you in car with the heating on? All of these will contribute to the 'overhead'

So there is no way to see charging stats via the car interface?

Only when it is charging.

Thank you

Have a read of the many winter range posts and you'll see there are tips for charging in colder weather to minimise the overhead.

yep, I was charging from cold without preconditioning.

Surprising tho that charging stats are not available without third party apps

Did any of your previous cars have this functionality?

LOL It is unlikely there were any discrepancies in the liters of petrol passing between the pump and the tank ))

 

[Shadar]

these discrepancies open up a gateway for cheating. If one cannot check the result one can never be sure in it. With petrol you can use a bucket

 

[init6]

How many of your previous cars came with a bucket? Got to supply your own? Exactly the same as the Tesla then

There are testers out there if you really don't trust the chargers, but as I said earlier, there are plenty of threads that explain where the 'discrepancy' is. Warm battery = happy charging.

The car reports what is actually added to the battery, it doesn't include shore based power used in battery heating or cabin heating. So, we get a benefit when supercharging as Tesla only charge for kWh added to the battery and don't charge us for battery heating whilst connected. Other networks just charge for the number of kWh delivered to the car in total. In your example, 6kWh probably went in battery & cabin heating and some in other losses from transfer inefficiency.

I would agree that this is a benefit, however in London Tesla charges 40-44p/kWh which, in my humble opinion, is excessive when there are other options available for 25p/kWh (50W ones so they are not slow). Even with overheads the difference is more than 1.5x. They choose premium locations I guess and it does not matter on a grander scale but no one will go to a petrol station charging £2.10 for petrol when there is £1.4-charging one around the corner
