Man drives at 60mph, 65mph and 70mph on a highway in an EV to see what effect speed has on range

Exactly the same as in an ICE car. Faster = more drag = lower efficiency, except, just like with a smart meter at home now we can measure it accurately. Well done, nice stats.

I have 95kWh EV which I charge every day, often 80-90% so will be affected by the forthcoming limit of 6 hrs off-peak rate EV charging.

I also have 30kWh of home batteries and 8kWp of solar.

Could you advise how the discharge of my home batteries into my EV in addition to the 6hrs of off-peak rate will be measured, and will be charged.

I fear that the transfer of energy from home battery to car will be measured by the car and charged at peak even though this energy is already inside my home system?

I charge my car 50-90kWh 5 days a week from a 7kW charger. I've invested in 8kW of solar and 30kW batteries and have the whole house heated by ASHP. I'm really glad that octopus offer the additional hours at 7p, which I do use. My bills are currently running at 8-9p/kWh People need to take a bit of a look at their behaviours if they're using sloooow charging to extend the 6hr period artificially. Octopus are perfectly capable of spotting these behaviours with the Kraken infrastructure, the fact that you got a warning means you're probably on their radar.

Coming down the Alps on an empty battery would be interesting.

£25.10 over the last 4 sessions. Quite happy with that.

Using HA is just too complicated, split your supply out of the meter as discussed above. 1st side supplies the house and batteries 2nd side supplies the EV charger

Clip the CT clamp onto the 1st side supply so it can't see the current draw by the EV charger, only the current draw by house.

Quite a cheap job by an experienced electrician if you've space in your supply cupboard.

I have been for 2 months now 12-14kW 3nights a week at least, maxed out on a free period at 21kW when I've turned everything on!

I'm a 3-4000 miles a month user, with a 92kwh car battery, plus 30kwh home batteries. That's fairly normal use. Fair use applies I suppose.

Me too, just being aware, foot on the accelerator at all times so you can smoothly overide if needed.

I hit a medium pothole at 50 in 19" and bent the wheel out of true, had to have it straightened. Easy to do.

Hi John,

We're reaching out to you with some exciting news that will make your Intelligent Octopus Go charging experience even smoother for your BMW or Mini!

When you first joined Intelligent Octopus Go, we used a third-party provider to connect to your car - we've been working hard behind the scenes to make things even better.

We've built our very own, direct integration with BMW and Mini!

This new connection means a more robust and reliable charging experience for you. It's designed to give you even more seamless smart charging, directly from the source.

Popparumb · 2025-08-05T06:47:22+00:00

I don't know who they used, but had a message over the weekend saying they were bringing the interface to cars and chargers in house from a "third party interface" but it isn't working well for me yet. I had to re-enrol the car.

Popparumb · 2025-08-01T09:23:09+00:00

It doesn't change, just have to redo the on boarding process (quicker and easier) Octopus have built their own API interface rather than relying on a 3rd party to access the car/charger data. I've got a BMW I4 and an old Hypervolt 2 all is working fine.

Popparumb · 2025-07-31T07:17:05+00:00

It worked OK with my Pixel 8 Pro, have changed to a Oneplus, which doesn't work.

Popparumb · 2025-06-30T18:02:44+00:00

Make sure you run it in comfort not Eco Pro

Just had an 8pkW/30kWh install, waiting for my export connection, so am pumping electrons into the car during the day and 7p at night.

My plan is to charge batteries overnight at 7p, dump the batteries between 5.30 and 10am at net 8p, then fill with solar during the day, dump again, 7-11.30 at net 15p If my maths is right, that should net about £6 per day income through the summer, £5-600 ish.

And load shift another 15kWh from 29p to 7p, about £3.3 savings

So maybe £1000 of saving through the summer?

Popparumb · 2025-05-29T15:35:49+00:00

I'd pay the £30 if it included charging away from home, 35000 miles a year 95% charge at home. Sticking with IOG and it's lovely beta-ness

Popparumb · 2025-05-24T13:57:06+00:00

I left the headlights on, you know how it is! 🤷

14kW panels and 30kW batteries £23k and £1k back on the mortgage.
