Octopus IOG over-charging battery?

[-Cappo-]

Looking for a little tech assistance here please.

My setup is Octopus IOG > Hypervolt Home 3 Pro > VW ID.7 Tourer

Only had the charger installed this week so I plugged the car in last night to make sure everything was working. The IOG app came up with a charging schedule, and clearly stated "Charge to 80%" - and still does this morning. The car is also set on the dash to charge to 80%. The Hypervolt can't be separately controlled when it's in "Octopus Mode" as the Octopus app takes control of that.

When I got up this morning, the Octopus app reported that the car had been charged to 100%, and when checking the car itself, sure enough it has been.

I know the Hypervolt/Octopus relationship is still in Beta, but (a) have I set something wrongly, or (b) might the Beta status mean it's not managing the charge level correctly? Or is something else at play here?

Shouldn't be possible if the car is working as it should. It controls ultimately when the charge can/can't charge.

The Octopus integration just removes the HV from the chain, Octopus also don't know the cars SoC.

So I'd check with the Pug forum. Could be an issue with the software.

Thanks. Pug forum? Did you mean VW?

Octopus are pretty responsive on twitter if you raise it with them.

OK thanks, I'll give that a go.

Just a quick check, my octopus gives me a 'Charge to add' value not a maximum charge. Has yours done the same? and added 80% additional charge rather than charged to 80%

The app showed this (when the car is plugged in it also shows the charging schedule, ie times)




I’ve tweeted Octopus & Hypervolt as suggested above.

Is IOG controlling the car or the charger?

If the latter, it may not be able to 'see' the cars SoC.


I also wouldn't worry too much, for nearly 5 years I've been charging to 100% at home whenever I plug the car in, I have seen no sign of degradation at all.

I had the same thing happen with my Taycan. I tried to override their useless schedules in the car and Porsche app but Octopus kept taking over again and again and full charging randomly when it was set to 80% in the Octopus app.

I removed the car from my Octopus account and now just schedule charging to end at 5:30am.

I believe it's controlling the charger. I guess I could try deleting the charger and adding the car and see how that goes.

Thanks re the 100% comment. I'm not overly concerned at present but I'm quite sure that if battery issues arise "they" will be able to download the charge levels and tell me to FRO!

[RobbyJ]

My charger is 'dumb' so it was only controlling the car but still totally messing it up!

When you say it was set on the car to charge to 80%, did you do that or was it Octopus passing it over to the car?

For IOG to work correctly you need to clear all schedules from the charger and the car and let Octopus handle it.

Your screenshot suggests that you have integrated with the car rather than the charger as its showing charge limit rather than charge to add. Charger integration should show charge to add.

On the Octopus app what does it show under devices, the charger or the car?

I did this too but when you do that in a Taycan it starts direct charging as soon as you plug it in. You have to manually turn off direct charging every time you plug it in.

If you have integrated with the car rather than the charger then it will start charging as soon as you plug it in until Octopus sets the schedule.

The car was set to charge to 80% as well as the IOG app. The only reference point I have is that when I have charged at a Supercharger, it charges to 80% then stops.

That's interesting. The only device in the Octopus app is the charger. I can't add the car as well. I could probably delete the charger and add the car I guess?

But also if you tap on the arrow next to the 80% charge limit, it says "Good to know: We won't charge your car beyond the limit you set in your car" long with a slide to alter the charge level - currently set at 80%.

IOG only works with your home charger so if the car was set to 80% and you plugged it in to a supercharger then it will charge to whatever the car says.

For IOG the car should not have a schedule set as its all done via the Octopus app.

True but in practice it can be hours before it sets the schedule, and then sometimes it charges to 100% not the 80% set.

Yes, sorry if I wasn't clear, I meant that as a demonstration that the car is capable of stopping a charge at 80%. IOG says it will never override the car. Hence I'm puzzled!

Yes, its not ideal. The consensus seems to be to integrate with the charger rather than the car where possible to avoid these sort of issues. Then you can charge any car and avoid the manufacturer pulling access to their API in future.

I have a Zappi and get a schedule pretty much instantly after plugging in but then I have integrated with the charger rather than the car.
