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.

The OVO anytime seems to charge at anytime during the day that there is a surplus  demand.

I set the Kaluza app to the time I need the car fully charged and my charger, an Indra, sort out the requirement. At 10p kwh its a no brainer. I have no knowledge of Tesla but once I deleted the time settings I had within the car system everything worked well.

When needing a rapid charge away from home it works in the normal way, seems like most rapid chargers are at around 70/80p kwh. I understand Tesla chargers have their own rate for Teslas.

What’s the verdict, @jwc2023 - is Charge Anytime with Direct to Vehicle or via a smart charger for you?

Hi - thanks for all the comments/replies.  Soooo it turns out my current supplier has changed its energy rates post 1st April and when comparing them to the OVO simpler plan, there is very little difference in both energy prices. Therefore, I have made the switch to OVO so I can take advantage of the reduced rate when charging the EV. I just hope this works as well as advertised.

I would like to ask, does it matter how long the car takes to charge i.e do you get only a set amount of charging hours or does it not matter how long it takes.

 

Thanks again all, much appreciated for the helpful advice/comments.

It won’t matter too much. You’ll get as many hours as possible during each Session, even if it’s not one continuous charge. :)

Nope! Just make sure you have the schedules set up how you like them. The system does the rest

Just to update anyone who was also asking the question on Tesla account access.  The Charge anytime app requests the login details for Tesla account, along with any 2 factor authentication code.  Lets just hope they stay true to their privacy policy...

Can anyone advise on the Anytime app in relation to savings etc.

 

Basically, when I go into the savings section its says just that, what I have saved, but is it not possible to see what the total charge actually costs? i. e. If I used 57.9KWh on a particular charge do I just times that by 10 pence. At the moment this is just telling me saved, but saved from what total amount if that make sense?

The savings should be against what your current electric tariff rates are. So if your tariff rates are normally say, 18.76p/kWh (I’m using mine as an example) the savings would be 8.76p/kWh.

Hope this helps
