Hey @NathanEV 

Welcome to the Forum.

It might be worth reaching out the Charge Anytime team about this as it’s doing it for both vehicles, it sounds more like an app or system issue rather than the car(s). You can contact the team via email at chargeanytime@ovo.com.

We’ve also got a really helpful FAQ about Charge Anytime that may be handy, as well as lot of topics about Charge Anytime here on the Forum.

Let us know if you reach out to the team and what they come back with.

@Abby_OVO funny enough I just got a reply just before your post. If you put a nudge in, Thank you :) 

Hey @NathanEV 

Glad to hear they got back to you!

I wish I could say I was that good, but this time it wasn’t me 

If you’ve ever any other questions, don’t hesitate to post on the Forum again.

Can I ask what the reply was? I charged my Mecedes for the first time overnight. Plugged in after work 5:30pm. It started charging straight away.

My charger app shows it added 20.5 kWh before pausing but my car reported receiving 17.3 kWh. 

It resumed charging at 3am, this time adding 12.2 kWh according to the charger but this time the vehicle reported receiving 8.9 kWh. 

It’s pretty much the same as your experience where the charging values differ by about 3 kWh each time. 

@billyrayuk  I had a really good phone call with the anytime team, I have not got to end of issues yet but was good to hear that they are investigating it and hopefully get some resolution as came up with what could be an issue for one of the cars. 

The OVO software on a basic level works out the percentage difference between when you start and stop charging, compared to your usable battery capacity. Using this and some other allowances gives the charge amount. 

We went through the Tesla data and most the time it was less than 5% out. 

The Mini PHEV though was 30% out. 

If you have access to your car charging data and your charger data compare the two together, I don't have any which give the same figure. This is due to a similar method on the car and charger just doing calculations. 

Realistically the best was to get the best results is to ensure you have the app set right, your car has a good connection to the internet before you start charging. Finally you have the car setup correctly for the Anytime App to control it. 

When I get any further with the Mini PHEV I will share it. 

Thanks for the reply! I’ll keep an eye on the values and make a note in case I need to query it with OVO.
