Tesla charging with Charge Anytime - does OVO need access to my Tesla account?

Hi - I am thinking of switching to OvO to benefit from the charging of my Tesla, I just wanted to ask, does the OVO charge anytime need access to my Tesla account. If this is the case, then this is a big data flaw/privacy concern.  

 

I ask this as I wonder how the app knows the car is being charged at a given time?

 

Thank you.

Hi @jwc2023 ,

As I understand things, Charge Anytime only talks to the EV itself, it doesn’t have access to the rest of the Tesla account and cannot make changes to it at all. Tesla would have reviewed what OVO/Kaluza wanted to do and worked with them to figure things out safely.

The system basically just asks the EV whether or not it’s charging and if so, where it currently is at that time to see whether it’s at home or not.

If you’d rather not do things that way, you can connect directly to a compatible charger instead which would mean Charge Anytime can’t touch your Tesla account or EV at all.

Hi @jwc2023 

Make sure to disable scheduled charging in your Tesla app so that it does not conflict with the Charge Anytime app.

The “Start Urgent Charge” button will instantly start charging your car at the normal higher rate - it won’t wait until midnight.

If you have 32A charging capability then midnight till 7am should be plenty enough time to top you up.  I also found with the Charge Anytime app that if my car charge level was really low that it would sometimes not wait until midnight to start charging the car.

What charger do you have?

Hi Domino138 - yes I never have the scheduled charging set in the Tesla app.

I know the start urgent charge wont wait, but is there a set time for example 8pm - 7am when energy is greenest, if so, then between those hours you should not get the option of an urgent charge, only smart charge?

I have a project EV charger

Charge Anytime is a type of use tariff, @jwc2023 - the tech behind the add on, Kaluza Flex, does all the hard work of knowing when the grid is green/cheap, so all you have to do is decide when you want your EV ready by and to what charge %. 

 

If you need the EV urgently, you can charge via the ‘Urgent charge’. 

 

Right, I have a new issue, unless I’m doing this wrong. A few times now I start a charge in my Tesla app, the charge starts then shortly afterwards the charge has stopped.  My car is at 77% so i wanted to top it up during the evening to 90% ready for the next day, at 1am this morning i had the same issue, starts charging for a while, then i wake up and the charge hasn't happened!  Any ideas anyone?

 

Hopefully now you’re only using this charge anytime app you’re seeing it correctly charge?

Ok so I proved this issue again last night.

I plugged my car in around 7pm, went into the app and the app said the car was charging, great! all seems good. I then check on the charge via the app around 21:00 and its stopped charging, stating ‘Charging next after 22:00’. 

So, I thought ok, greener energy after this time perhaps? I check back in the app after 10pm and indeed it did start charging. 

However, I then wake up and it has stopped at some point leaving me with still only 45% charge.

At this rate I may need to switch to another supplier as I’m clearly not getting the cheaper rates i singed up for, and I’m being left with an un-charged car each morning! Not impressed up to now.

Sorry to hear this, @jwc2023 - I totally understand you need this sorted. 

 

If you’ve turned off any scheduled charging from your Tesla app, you’re not using it to manage charge and you’re still not able to get to your requested charge % by your ready time on the Charge Anytime app, it does indicate an issue. Please flag this to our OVO Smart Home team and feel free to link them to this topic to save you having to type anything: ovocharge@ovo.com.

Did you get a resolution to your charging issue? I have a Model 3 and it works perfectly. I just leave it set to be fully charged by 6am. It usually starts charging for a minute and then decides when to charge. I have seen it stop and start which I assume is based on low/high grid availability, but it has always been charged by the end time. I leave   the charge limit set to 100% in the OVO app as the charge limit you set in the   Tesla app will stop the charge so it’s then the same process charging at home or at a charger away from home. It’s also then straightforward for my partner to charge without knowing anything about the Charge anytime app. I assume the Charge Anytime app checks the Tesla charge limit when estimating how long you need to charge the car. I do like that you aren’t restricted on times you get low cost charging as you could set the car to be ready at anytime day of night so it’s very flexible. 
 On security, the app does know whether you are charging or not and where you are as it will show whether you are charging when  away from home, in which case you obviously get no credits. 
 If I had a compatible charger (mine is a Hypervolt) then I would use this but I’m pretty happy with the process as it is.

My Tesla, home charger and charge anytime app has worked well for many months. Today having set up a charge anytime, the app continues to say the charger is not connected to the Tesla. The Tesla is charging but not as a result of the app.
I rebooted the charge anytime app, problem persists. It doesn’t seem to make a difference whatever I try.

Hey ​@WMullins 

 

Did you get in touch with the Charge Anytime team about this? 

 

There are a few steps you could check in the meantime;

 

  1. Check the App Store or Google Play for any Charge Anytime app updates. You’ll need version 2.0.10 or newer.
  2. Reconnect your car in the Charge Anytime app by 5th April by following the steps below. Please have your Tesla login details and key card to hand. 
  • Disconnect your car from the account in the Charge Anytime app.
  • When in your car, connect to Bluetooth in your phone’s settings.
  • You’ll need to put your key card in the centre console (the storage area between the front 2 seats) to pair your car with the Charge Anytime app.
  • Reconnect your vehicle by following the onboarding steps in the Charge Anytime app. 
  • On the Vehicle found screen, select Setup. 
  • Don’t select Connect with limitations. This won’t allow you to connect to Charge Anytime. 
  • Enter your Tesla details into the app. There might be a short delay while it connects to Tesla.

If you have any questions, you can contact the Charge Anytime team who’ll be happy to help.
