Intelligent Octopus Go limiting cheap charging.

paulstevo

Question?
If I continue to have the only charge with the dynamic charging tab ticked will I never incur the bump charge price?
Im currently running an Audi Etron 55 which only now and again requires over 6 hours if I run it from low to 80%.
Will the charge stop at the 6 hour point and not continue to charge at a higher rate . I run the Ohme pro charger not interfaced with the Audi app due to niggles . My usual routine is I set required target in Ohme app to 80% which then assumes the car is at 0% this then charges to the 80% that the Audi is set too in car at whatever % it is sitting at. It stops when the car reaches the required 80%. Haven't tried to get all elements to talk to each other after last issues were car did not reach required charge. This method has been stable for nigh on 6months .

No, not as it currently stands. Ohme can schedule more than six hours of dynamic charging in a day, and (if I'm reading Octopus's announcement correctly) if that happens the excess will be billed at the day rate.

Not unless Ohme change things at their end to prevent exceeding 6 hours of charging.

EVs do not depreciate any more than ICE vehicles, in many cases they depreciate less. You are demonstrating a very inaccurate understanding of depreciation. 

The industry appears not to agree with you.

Glass’s June 2025 market update also revealed that in May 2025, the overall average depreciation at three years/36,000 miles across all fuel types was 49.3%.

The breakdown of average depreciation by fuel type was as follows:

• Petrol: 47.1%
• Diesel: 47.6%
• Hybrid electric vehicle (HEV): 44.2%
• EV: 61.1%

This data makes it clear that the average EV loses significantly more value than other car types during the first three years.

Those figures are totally meaningless because they are not comparing like for like, EVs mostly sit in higher segments, so depreciate faster, as all higher segment cars do.

Not sure about your claim about the EV cost premium vanishing, as a quick glance at Kia's new vehicles listing shows the entry model of the EV5 (the equivalent electric model to their very popular Sportage) coming in at £39,295 compared to £28,710 for the entry level Sportage.

Again, meaningless because the difference in segments for most EVs. The comparison of the EV5 to the Sportage is not like for like, the EV5 is a higher spec car. 
A better comparison would be like for like, so using Kia the Niro makes most sense, a 4% difference, totally wiped out bye the first years fuel costs. 
Kia Niro 4 Petrol £38,315
Kia Niro 4 EV £39,995

Your posts would appear otherwise. They are well past their infancy, they are a mature technology and whilst government tax increases will make them more expensive to run over time they will still be considerably cheaper per mile and TCO than ICE vehicles.

Nope.  Admittedly I'm against BEVs because on average they're about £20k more expensive to buy and they suffer by far the greatest depreciation (see above).  But I drive a self-charging EV, which has the lowest depreciation ! 🤓

Did you also know that a BMW M5 is considerably more expensive to buy than a Ford Ka? Would you like any other pointless comparisons to add, maybe that it is more expensive to fly to Australia than Paris, or that a high spec PC is more expensive than an entry level model? Comparing vehicle cost by fuel source is totally pointless unless one also accounts for vehicle segment and spec. 

WiserMiser said:

The recent announcement about the introduction of eVED is likely to cause a big slump in BEV and PHEV sales.

It is unlikely to do anything in real terms, the running costs and TCO of an EV are still much cheaper than an equivalent ICE vehicle. Currently EVs cost around 1.8p per mile on fuel, add in the per mile charge at 3p and it goes up to 4.8p per mile, which is still around a quarter of the cost per mile of an ICE vehicle.

You can keep trying to compare vastly different things, but it really is not helping you present your position as factual or rational.

This requesting a higher percentage than necessary is why Octopus are clamping down. It's gaming the system by forcing more charging outside of the off peak hours, so getting the whole house at cheap rate.

in answer to your question, Octopus/Ohme are looking to put a control in their apps so you can choose to cut off the charge at 6 hours or allow it to continue to the required charge accepting the amount over 6 hours will be peak rate.

Interestingly, when I attended the Kia EV4 & EV5 launch event at my local Kia dealership at the end of August, the staff told me that the EV5 is the "electric" Sportage, and although they will still produce the ICE Sportage until 2030, they were quite clear that the EV5 is its eventual EV replacement. However, what do they know...?

It does not really matter what they told you, an EV5 is not directly comparable to a Sportage. When we compare two directly comparable vehicles, the Niro Petrol and the Niro EV there is only a tiny difference. You are deliberately choosing a dishonest comparison to try and make a point and in doing so you are disproving the very point you are attempting to make.

Back to the IOG 6 hour limit, what I've not seen from Octopus is how they are going to charge for overnight periods where there is some "peak smart charge greater than 6 hours".

eg, 

- I plug in my EV during the evening and get 7 hours smart charging, 19:00 - 02:00
- I run my tumble dryer at 01:00 - 02:00

Octopus are saying that for EV, I'll be charged 7p for 19:00 - 01:00, and peak rate for 01:00 - 02:00, but that the rest of house will be charged at 7p for 01:00 - 02:00

What will my bill look like for 01:00 - 02:00?

Chargers are not calibrated devices, so Octopus cannot use that for billing, which means the only way they could do this is to charge peak rate from 01:00 - 02:00 and then apply a bill credit by taking the EV charge reported to them by the car/charger for that period of time from the meter usage during that period of time. But, that usage will include charge losses (up to 20% for a granny charger).

The smart charging limit is 6 hours per day.

1900-0000 is one day, 0000-0200 is the foollowing day. You've had five hours charging on one day and two hours on the next. No problem.

The problem still exists, but only for 2330-0000.

The simplest way for this to work would be for Octopus to split the "day" at 2330. Then the day would start with six hours of cheap-rate whole-house electricity, and there's no possibility of peak-rate EV charging coinciding with cheap-rate whole-house electricity.

We'll have to wait and see what the details are.

Octopus have stated measurement period for 6 hours is midday - midday.

If they've said that, there's two possibilities:

- They've given it less thought than I gave it when writing my reply; or

- They've worked it all out and just haven't told us the details yet.

Take your pick.
