Fuse dropping a tariff and Tomato entering admin is more due to unsustainable market practices. Of course, truth doesn't matter, won't stop people fitting their own narratives. IOG bringing in rules to stop people gaming the system I am fully aware. In fact, I recently joined Octopus forum and reading all the responses. But IOG changes has nothing to do with reduction in time of use tariff. It is due to people reducing charge rates in order to game the system and get more than 6 additional hours defined as fair usage in T&C. New rules will enforce the 6 additional hours smart charging (still for everything) on top of the overnight 6 hours off-peak for everything. There is no reduction in the actual ToU tariff and off peak is still same price. Octopus are fully aware of people gaming the system and have been attempting to fix that for a while. A few months ago they sent Emails to those identified as first attempt. Now they are changing the rules to enforce previously "fair usage". It shouldn't affect 95% of the users.

Have I missed anything? Which tariff recently reduced cheap hours?

For Mini, what about the 3-door Cooper and Aceman? How come only the ugly fat one got the grant?

Do you mind sharing link/how to sign up to this? If it's open to the public? On mileage checking, I suppose Tesla could do mileage checks remotely on the cheap. It's been over 3 years, my Tesla has only ever been seen by MOT tester at almost 3 years old. Apart from initial niggles sorted out by warranty, it has not need any servicing and I've only spent £20 on wipers and £50 on MOT over the 3+ years of ownership. There's no chance in hell I'm wasting time visiting + wasting money paying a garage just to log my mileage in order to pay tax. Although both electricity comes from battery. 1 kWh of heat from resistive PTC heater need 1 kWh of electricity. 1 kWh of heat from heat pump only need ~0.3 kWh of electricity. Heat pumps make energy go a lot further. Opposite of hydrogen conversion, carbon capture and ICE, where energy are wasted.

Details emerge in govn publication: "4.29 Cars under three years old are not currently required to have an annual MOT. The government currently intends for these cars to attend an additional mileage check at an accredited provider around their first and second anniversary, but welcomes views on whether these additional checks should be required. For many motorists, this will be able to be combined with other routine servicing and safety checks that their vehicle will typically require in this period. 4.30 The government considers MOT test centres to be well placed to be these accredited providers.15 They already have facility to record mileages and are trusted partners of government. There will be no motorist charge for these additional checks, which will be funded by the government. The government will engage with the industry on these arrangements. " "4.41 Vehicle changes ownership: The mileage already paid for will remain with the vehicle. This mileage – which may be either more or less than the actual mileage accrued at that point, as per the vehicle odometer – will be made visible via DVLA online to the new owner (i.e. the buyer). The government expects the eVED status of the vehicle (whether it is sold with pre-paid mileage or a mileage deficit) to be reflected in the sale price of the vehicle.

Minimum IOG amount on Octopus app (assuming you haven't got Ohme? That's a different system) is to add 10%. But if you ask for car to be charged (+10%) and ready in the following hour for the morning, it will force their hand and give you cheap slots. The slots are only active if your "smart device" (their T&C wording, in case of IOG, it is the connected EV) is charging. So if your car becomes full within 10min, you'll only get that first 30min at cheap rate. So in your example, you will get 30min to 1 hour of cheap rate, depend on how much your car charges. Depend on your charge point. You can also keep IOG smart charging turned off. With my Indra charge point, it would just flash white for waiting for schedule, wouldn't charge unless I press BOOST button on it. I can then turn on IOG smart charging in bed instead of go out and plug it in. The end result is the same, IOG detects smart device and allocates a schedule.

For those missed it, here is a thread for the confirmed pay per mile tax:

The 3p/mile tax is in addition to VED. Just as fuel duty on fuel sold at the pump is in addition to VED. To calculate equivalent, you need to find how much litre you use per year. Multiply by 52.95p/litre and then divide by your annual mileage. The fuel duty now is 52.95 p/litre. It was frozen all the way back in 2011 and includes additional 5p discount. Accounting for inflation, it should be around 85 p/litre now. Simmons Gainsford LLPWhat is fuel duty? | Simmons Gainsford

It's all about sending the right message. Now it's: fuel price has always been like this, the tax is not well publicised. But buy an EV and you'll need to pay extra tax. It should be: all cars use the road equally so pay equal tax per mile. Fuel duty reduced accordingly so cost of running fossil fuel car doesn't drastically change. Then the message is crystal clear: use of fossil fuel incurs additional tax for their pollution. I think a long range EV with range extender as the Chinese are rumoured to be bringing will be the right vehicle to get with this tax scheme. Crazy government is incentivising more vehicle with ICE to be on the road.

It's official: BBC NewsElectric vehicle owners to face pay-per-mile taxDrivers of electric cars will pay a road charge of 3p per mile, while plug-in hybrid drivers will pay 1.5p per mile from April 2028. " The Office for Budget Responsibility's (OBR) document has stated the charge would mean electric car drivers will pay a road charge of 3p per mile, while plug-in hybrid drivers will pay 1.5p per mile from April 2028, with the rates going up each year with inflation. The government said the new tax is about "half the fuel duty rate paid by drivers of petrol cars", the report says. " This is whilst removal of 5p fuel duty discount is not removed, again. I think the messaging is all messed up. Buy an EV and get punished whilst fuel duty levy hasn't kept up with inflation. But at the same time, effectively give manufacturers backhanders for emissions to manufacture a brand new EV.

The price of UK electricity is not linked to renewables, that's the root cause of our price problem. It is linked to fossil fuel: https://www.livecharts.co.uk/MarketCharts/ngas.php https://www.bbc.co.uk/news/articles/c2lplg7d9ewo See that price cap spike at Q2 and it's now going up again together with gas price? See the extremely clear correlation? Would be interesting to see what percentage of those goes to fossil fuel companies.

With Ohme, can you revert back to timed charging 23:30-5:30 and not use VW app? Probably best keep everything linked if possible. Only use IOG smart charging on days if it's not working it's no big deal. With my Indra charge point, IOG only talks to Indra. No car app involvement. I can put charge point into dumb mode (boost mode: always dispensing). Then set schedule in any of the cars, offline from everything else if needed.

"times" is the important bit. Leafspy only records (or BMS only records and Leafspy only shows) number of times charge was started, or connection made. It doesn't actually record amount that was charged. Intelligent charging stop/start on AC charging also increments the count by 1, so IOG charging overnight could gain a half dozen more L1/L2 charges. V2H/V2H connection on Chademo will also count as 1 QC. I know it probably isn't the case for the van in the video. But my one is certainly racking up QC at alarming 300 times a year.

Is there any tech-bulletin with Ohme or VW? Worth probe them for compatibility info/updates. My parents' Renault Megane had compatibility problem with Zappi. After some searching, it turns out Renault need to do a firmware update to make it compatible. https://support.myenergi.com/hc/en-gb/articles/21802420976657-Troubleshooting-Charge-Delayed-Notification-on-the-Renault-Megane The symptom is exactly what you describe. Charges fine on first plug in or first scheduled charging session. But fails to wake up for subsequent charging sessions. Though this is a lot easier to debug due to it ALWAYS happens. But Renault still threatened to charge diagnostic even though we sent over the Zappi page with Renault's own ACTIS number. The vehicle is sold as supporting OTA updates, clearly not Tesla level, no OTA on all systems. Stupid traditional manufacturer and dealership shenanigans.

That curve is discharge test. It is saying to get 100% out of the battery, one need to discharge from 4.15v down beyond 2.75v. 400v cars are not 400v, they vary depend on battery configuration. Just as 800v cars are typically 600 to 700v, depend on battery configuration. The "architecture" only talks about the general voltage range, the components such as air-con compressor or motor inverter will have matching voltage range to hit their performance target. The EV as an unit would be designed for pack's voltage range and quoted power would not be affected. But outside of EV, this voltage difference do affect DC charging performance. The older Ioniq 28 kWh has faster charging than newer Ioniq 38 kWh at old current (amp) limited stations because of battery configuration resulting in higher pack voltage. It's not really something that is noticeable during every-day use though.

Instead of dragging the car fire thread off topic, I'll reply here: Indeed: InsideEVsThe Safest Cars On Sale In Europe Now Are Chinese EVsThe Tesla Model 3 keeps its position as Europe’s safest car, but it too is made in China, and is followed by mostly Chinese cars." The overall ranking still has the China-made Tesla Model 3 at the top, even though it has a lower occupant protection score of 90%, but it makes up in the other categories. The surprise second-place entrant is Nio’s Firefly, with its 96% occupant protection score, which is the highest Euro NCAP has ever recorded. It’s followed by the Tesla Model Y, the Smart #5 and BYD Seal 6. "

I thought you are connected via Ohme? The car cloud API only used to tell Ohme the car's SoC. With Octopus stopping and starting charging, those notifications are normal. I get one each time Octopus stops charging. However charging error notification is interesting, what does it say exactly and do you get explanation of error when you open it?

Again, me, me, me, me. Not willing to see the much bigger picture.

It is a case of risk management. Lower chance but extreme damage. I'm sure shipping companies are well aware of this. Probably charge accordingly. Holistically, it is also a question of which is less worse? Continue to ship and sell millions of ICE cars burning fossil fuel for 10+ more years, or the tiniest of chance EV shipping burning up until mitigations are put into place? There is no panacea. No magic cure. EV fires seem devastating but they are the best solution we currently have to stop mass burning stuff for trivial daily errands.

Do you have any individual energy monitoring devices? Or the charge point app? Or car charging history? I've noticed IOG been tweaking their backend slot allocation algorithms. I'm getting a LOT more frequent slot re-allocations. But not had problems though charging on IOG, only problem was my home battery automations not reacting fast enough to their frequent slot updates. I think possible reasons for partial charge: Charge point auto de-rating due to house load, check via energy monitor mentioned above, see if car was not drawing full 7 kW and if total house load is near 80% of your main fuse rating. Intelligent Octopus Go mess up, check by looking at IOG schedule, was enough slots allocated? Was there internet problem at any point throughout the night? Perhaps IOG slots was updated and your charge point didn't get the memo? I've never had problem charging in the cold, I've not seen the EV itself slowing down AC charging due to UK cold weather either. This cold is nothing compared to what they get in Norway or Canada, yet they charge and drive EV's no problem. Hence I'm thinking it's something outside the EV itself.

This bit I find critical going forward, from auto translator: " ‘Transport EVs must be safer, existing ships not suitable’After their findings with the fire on the Fremantle Highway, the Panamanian investigators recommend measures that should make transport of EVs on all ships – including ferries and passenger ships – safer. Because it has become clear to the researchers that ships that only have a fire extinguishing system for transporting cars with an internal combustion engine, now also transport electric vehicles ‘without any upgrade of their loading floors and firefighting’. ‘Panama’ calls the risk of fire in electric car ‘minimum, but the consequences ‘catastrophic’. For example, tailgates on existing ships have not been built for transporting electric cars. This can damage the batteries that are in the soil of EVs, which can cause a fire. " I wonder how Norway ferry are dealing with this change of risk, they even many electric ferries.

I expect there's buffers being used up as part of degradation. For example, 93% of battery capacity was used when new to produce WLTP range. Degradation report now says 10% degradation, so that now eats into WLTP range and thus 3% of WLTP range has been lost. First 7% degradation would be invisible to end user. I expect Audi to have even bigger top buffer. They rapid charge very quickly at the top SoC. Nissan Leaf does similar trick where first the health bar is lost at 15% degradation rather than divide the 12 bars equally. And at end of vehicle life, battery can be re-used for stationary applications. At very end of battery useful life: InsideEVsWhy China Is Quietly Winning At EV Battery RecyclingThanks to new techniques, some Chinese companies say they can recover 99.6% of the key battery materials like nickel, cobalt and manganese.From that article, this company is currently recycling 120 thousand tons of battery aiming for 1 million tons, with above 90% for all rare earth materials. https://en.brunp.com.cn/services-products/recall " In the U.S., Redwood Materials is one of the biggest battery recyclers. It says it too has technology to allow it to recover up to 95% of the nickel, cobalt, lithium and copper from an end-of-life EV battery pack, but it has yet to do it at scale. The company wants to use these recovered materials to create new battery packs and is targeting a production capacity of 500 GWh by the end of the decade. "

AutocarThis Volkswagen proves EV batteries last longer than you...The German Automobile Club has shown that EV batteries can stand up to hard use " The German Automobile Club (ADAC) recently published the results of a four-year test using a Volkswagen ID 3 Pro S Tour. It took delivery of the 77kWh EV in May 2021 and various drivers contributed to 100,000 miles driven. The battery was repeatedly checked at the independent Bavarian Test and Technology Centre during the test. The SoH was 96% after 13,500 miles, 94% after 52,000 miles and 91% after 90,000 miles a figure within the expected range. " and in an unrelated group test: " In a large study of its own, involving 402 EVs of the same brand and battery type, the company found that "moderate driving behaviour" reduces energy consumption by 10% over a battery's life cycle. "

This feature is called "Plug and Charge". https://electroverse.com/community/ev-blogs-and-guides/what-is-plug-and-charge It is part of ISO 15118 https://en.wikipedia.org/wiki/ISO_15118#Plug_&_Charge (note, mileage is not part of data being exchanged) But as with all things, support is on a car-by-car basis. Many vehicle technically could be isn't being updated to support this. My parent's MY2024 Megane for example doesn't get any feature updates what so ever.

Good point on hybrids, how do you tax that without an existing counter to count electric-only miles? I think the fair and KISS way is to roughly pro-rata reduce fuel duty and apply 3p/mile on all cars. Would be interesting to see how they want the reporting to be done.
