Keeping the car connected to the charger

[HCS_UK]

If you are not planning to charge car, do you keep it still connected to the charger? I found that even car is scheduled for charging off-peak hours, car starts charging and stop on peak hours (very briefly like 4-5 minutes when I am inside). Which option is best for battery? MY24 RWD (2023 manufactured)

IO is not working on mine. If I leave it, It starts charging car with peak rate

Watch out for scenario where battery SoC is at a value where IO does not need to charge, eg IO limit < SoC. In this case car will start to charge at scheduled car time and not stop until it hit the in car limit - ie exactly the same as car and battery schedule/limit. This may not be what was desired.

IO prioritises the SOC. therefore I always have 100% target on Octopus app and adjust my car SOC target only.
If you set car to start charge at 23:30 then IO will create the charge plan according SOC target. It might be that charging will stop after 5:30 but that will be according IO schedule anyway.

Nevertheless, In 6 hrs you can charge 48 kwh which for RWD would be close to 80% of the battery even without IO scheduling

It ALWAYS starts charging at peak rate. it stops between 1 to 20 minutes after start of charging. that is how IO works.
It starts to charge at peak rate (you can stop that charging at peak rate via app or in car yourself) and then restarts when Io schedules whole charging.

Unless your car has no data connection where it is parked.

FYI - I dont have any experience with cars controlled directly to IO but my connected charger is pretty much instant every time.

that is literally how IO works with cars.
it has to detect that car is connected to charger at home (location + charger in) and then sets up the schedule.

What I meant is that its instant and never charges on peak rate .

yeah, because it works with charger which is always on.
In my case I have pod point which has no such integration with IO. but I use the Home assistant to achieve the same

Might be worth a how to since these were very popular back in the day

it is in the massive IO thread Wiki - Everything you wanted to know about Intelligent Octopus But Were Afraid To Ask

It is off-topic but I can share my test results about controlling car charge with Octopus (IO) and Tessie

Tessie controlled the charging successfully with automation function. On the other hand, octopus failed to control it.

how did IO failed to control?

how did IO failed to control?

It should initiate charging 02:30 am according to Octopus app. It did not

was your car with cell coverage?

Car is connected via WiFi plus cell coverage is pretty good. Another proof is that Tessie could control it.

I actually have some issues when car is connected to WIFI as well.
try to turn off the wifi and see how it works.

in my experience, no wifi - is also quicker to connect to car via app..

looks like when car sleeps wifi is off as well at some extent
