Although now I have even less idea why vehicle batteries and household batteries are not drawing predictable current!

OP, have you got an economy 7 meter or something? I'm just wondering whether it's possible the current is taking a slightly different route to the charger at nighttime and if some component in that route could be limiting the current in some way.
It might be worth posting on the SpeakEV forum, it seems there are a couple of people on there who are pretty experienced electricians and post a lot on the chargers board.

Good idea - I will do just that.

Thanks to everyone for your input. Much appreciated.
I suspect I may be embarking on a tortuous road to resolution, but I will report back on my findings.

Ok my issue is fixed.
It was the charger.
My installer told me it needed a software update to run at 32A overnight, for some reason.
Then it started to trip out after a period of charging.
This was solved by my installer fitting a 40A fuse, as the EO Mini Pro 2 is/was ‘sensitive’ with ID3s, so I was told.
All working perfectly now on scheduled charging via the EO app.
Many thanks to those who offered their advice and tried to help me solve this issue.

Hi Mandarinfish,

I’d been keen to understand your home charging setup. I’m due to have an EO charger installed in the next couple of weeks and have been advised that there will be an isolator and an earthing unit fitted (assume Garo).

For info I have an 80A single phase supply, with a recently updated Hager dual-RCD consumer unit.

Many thanks.

I have the same issue, most nights on octopus go I get 15kw total,however, if I am still awake after the charging starts and I turn off and then back on, most times it will switch to 7.3kwh and supply 30kw. No idea why?
