the truth about electric cars
Who pays for install and operating cost of those public infrastructure? Nothing is ever going to come for free. You want to use public infrastructure? Pay for it. You want to get it faster? Pay more for it just as you do with liquid fuel. Difference is EV's have the flexibility to charge cheaply at slow rate. Only remote possibility of something like this would be overnight where grid wholesale price are low. So that after adding CPO operating costs, it is somewhat comparable to charging at daytime domestic rates. From grid emission point of view, I think any tax on EV charging should be tied to amount of fossil fuel in the grid at that time. I think it's reasonable to pay more than fuel duty if charging 5-7pm when there's the most fossil fuel in the grid mix.

the truth about electric cars
https://electroverse.octopus.energy/ It has been a chicken and egg problem from 2017 when I started experiencing EV's. End of the day, it's just about getting the right tool for the right job. Getting 100 miles range EV and regularly drive beyond its range is only someone mad would do (😘 toot) Rapid charger infrastructure need to be built sufficiently so that it can keep up with majority of holiday demand. Building more is wasted resource. Building less stifles adoption. Savvy drivers are flexible and charge up at less busy locations by looking at utilisation before coming off their route. From my personal experience, I can say Tesla at very least seems to have done well and I experienced zero queuing during end of May bank holiday.

the truth about electric cars
With the 2014 Octavia I had, it worked by measuring rotations. If wheel rotation is different between 2 wheels across the same axle it will alert. There is no actual TPMS sensor in the wheels. That is why it can accept "wrong" pressure and must be reset manually. Tesla (and 2014 Nissan Leaf) has TPMS sensors, Tesla uses BLE sensors. Leaf uses 433 Mhz sensor (I'm pretty sure, but not 100%). I've found Tesla has a very dumb algorithm: if <38, then show alert. if >40, then cancel alert. So if I set cold tyre pressure to be 40 psi in summer, as temperature drops, I'd get warning in cold mornings and have to top up to at least 40 to remove the alert message. Car screen says recommend 42 psi cold. I try to run them at 40 psi for slightly less jiggly ride.

the truth about electric cars
5 hours * 70 mph = 350 miles. Easily done with Model 3 LR RWD rated at 436 miles WLTP. WLTP is 436 miles. That is well over 6 hours on the motorway. I have built in 20% decrease in expected range from my real world experience on a bigger, older, less aero same brand car. It is an old myth that EV burns through battery on motorway. It was true for likes of Nissan Leaf because its battery is small and has horrible aero. Model 3 are known to achieve well over 4 mi/kWh on motorway at questionable legal speeds. It is the most efficient mass market EV on the market. Data from 2023 M3 LR RWD, before 2024 facelift aero improvements. It got 4.33 mi/kWh, post claims average 69 mph for whole 4000 miles trip. https://www.speakev.com/threads/model-3-long-range-rwd-436-miles-wltp-available.187523/?post_id=3672392#post-3672392

the truth about electric cars
Tesla have released the Model 3 LR RWD and Model Y LR RWD. Model 3 LR RWD - 436 miles WLTP - £45k Model Y LR RWD - 373 miles WLTP - £47k The Model 3 is 5+ hours and MY is comfortably over 4 hours zero traffic motorway driving in vast majority of UK weather. The Model 3 is only 14% more than Golf GTI and cheaper than Golf's most expensive trim level. The 3's performance sits in between the two, with similar amount of equipment and more interior space. https://www.volkswagen.co.uk/en/new/golf.html#build https://www.tesla.com/en_gb/model3/design#overview

the truth about electric cars
The bold bit, I think you need to go back to school and learn how probability works. Or have a look at basic principle behind statistical analysis. I'm sorry, what context? Are you okay behind the keyboard? Because all I'm reading is a lot of illogical conjectures. Let's break it down: Why does this time to refuel matter in the real world? Do you teleport to petrol station pump and then teleport back? In the real world, only thing matters is when you are not making progress. I'm sure you are keenly aware, because you keep pointing out you are a busy man. The idea is not whether you can determine when you need to stop during a trip. The idea is that for sake of our discussion, without prior preparation, you cannot say you can travel 600 miles at start of the trip. The distance you can travel is non-deterministic in the context of our discussion (ah context, you must know a lot about it). Whereas with long range EV and driveway, the trip starting distance can be guaranteed at greater than 250 miles. For example, Dom's trip started with lowish fuel. Your trip may have started with full tank. That's because you've done aforementioned preparation before the trip during your very busy schedules. All I'm going with is what you've posted. And you asked whether I agree. I do mostly agree with your statement as I quoted and stated. At no point in my previous post I even thought you were EV bashing....... strange that you elect to say this......

the truth about electric cars
Yes. totally agree outside your brackets. We are getting there. If we want to be 100% comparable, time to refuel liquid fuel should start ticking the moment car deviate from original route and end upon re-joining original route. It should include any time spent queuing should there be a queue and for long journey, any time spent going to the loo/herding passengers. Time to recharge is similar. Time starts from deviate from route and end upon re-joining. If refuel at petrol station is another stop (for cost), both comfort break + secondary stop should be counted. Same for EV recharging, it's only fair. But reality is that EV doesn't need this until more than 250 miles or 4+ hours have been driven (if driveway = true), whereas ICE must have minimum of 10min preparation before trip or otherwise when it needs refuelling is non-deterministic. Could be less than 100 miles into the trip and a comfort break isn't needed. The point is re-energise being slower from 5min (ICE) to 20min (EV) is not important if car is going to be parked for roughly that duration anyway. 5min at petrol station + 15min at service = 20min rapid charging at service. Similar amount of time not making progress. This question is better directed at @domhnall I'm afraid I have zero knowledge of what you are trying to do, I only have experience with Tesla. (and 2011-2016 era Nissan)

the truth about electric cars
Correction. In case of Tesla at Tesla supercharger, No need to account for faffing about with payment, it is automatic and handled by the car. Plug and charge is coming for other vehicles on other network very soon. Don't forget Dom drives a Skoda, which (will?) support plug and charge: https://www.skoda-storyboard.com/en/emobility/just-plug-and-charge/ Also, time spent rapid charging should only be counted if needing to do any extra waiting after doing what one already need to do during comfort breaks, For example, if you run to the toilet and run back at midnight when it is empty and possible to do it in 5min, then the other 15 minutes out of 20min counts as charging time. But reality is typical service stop period is around 15min just for toilet at a leisurely pace. I have tried to hurry passengers whilst driving my Octavia and they didn't like it. Before buying full BEV for long trips, I've timed multiple rest stops and 15-20min is normal, <10min is only achievable if trying hard and very stressful for everyone. Looking at my trip log (TeslaMate), we meant to do a very quick toilet stop at the A82 service, no charging just stop, toilet number 1, comeback and drive off, at 3pm, still took almost 15min and parking cannot be any closer to the rear toilet entrance.

That's not how the forum works. If you continue to post disinformation (more damaging than misinformation) and FUD, then be prepared to have it questioned, fact checked and ousted. If you don't like your posts to be questioned, save yourself and stop posting FUD, do some very basic fact checks yourself.

the truth about electric cars
You just can't help and move the goal post again. It is about planning fuel up's now? So your post on cost was pointless? Your point about 5min fuel up in the previous post no longer relevant? As mentioned, during everyday driving, EV are more convenient and actually less time spent, don't even need to think about fuelling up. For longer journey, rest stop naturally happen and simply plug in when resting. Planning not required if in-car sat-nav software is good enough. For day trips where total driving is around 4 hours in total on motorway, or 6 hours around here with a bit of local traffic at either end, EV doesn't need any planning or preparation. Whereas with ICE, as you've previously said, need to check and possibly fuel the day before, taking 10minutes minimum even if the fuel station is literally next door to your house (get dressed, start, drive around, 5min fuel up, drive back, change into comfy cloths. Ok, may be 6 minutes if you go out in public in your PJ ) I have plugged in the Leaf in my PJ before. Leaf BMS records how many charger connect/disconnects. It is also very poorly connected in terms of app control or Home Assistant integration. So when wife told me she want 100% next day for driving to shopping centre, I had to go and plug it in. 11pm in a Close, 5 seconds, no one saw 🤠In other news, my Powerwall was meant to be installed today, installer sick, had to reschedule to 18th. 😞 New phone coming today though, I'll be using the new 80% charge limiter and see if it makes any difference. My current iPhone 12 mini that has seen battery use around 140% every day is still reporting 83% health at 4 years old. Conservative estimate with 120% battery use each day puts it at over 1750 total battery cycles so far. Modern batteries really do last and can take a beating. Meanwhile, my Tesla vehicle BMS says it has recorded 94x discharge cycles (I run sentry mode all the time when not at home). I'm confident it can last more than 1000x cycles. Extrapolate from current mileage means ~200k miles zero worries and zero service requirement on the whole powertrain.

the truth about electric cars
Moving the goal post much? Where in last page have petrol/diesel price been mentioned? All throughout I can only see talking about time taken out of a trip. Are you in any way making a link that fuel price impact time taken to refuel due to higher demand? I'd agree with that because it's supply-demand-101. But I thought your main talking point were that liquid fuel are pumped at same rate? FWIW, I used to fuel up at an Esso a bit off J9 M1. Adds ~15min to my 40-45min morning commute because coming back on to motorway is more traffic and there's usually a small queue (never pump available on arriving). That Esso is the cheapest even compare to cheapest supermarket around my home. I got a fuel card through some deal and it takes further 3p or 4p off. Driving the same commute in EV doesn't add any time to the journey. Only 2x 2 seconds plug/unplug each day. Maths question time, which takes longer, 8x 2x 2 seconds or 1x 15min? Or even against 1x 5min to "brim the tank". Answer, 8x 2x 2 seconds is 32 seconds. I can't see how people can say standing around holding a fuel nozzle for multiple minutes is quick and convenient. Of course, owning driveway and all that. Hence I've always said EV should be first consideration for those suitable, but there's many suitable who are still buying brand new ICE and parking on their driveways. It's all because of FUD against EV's being spread.

Tesla Model Y SUV, will be launched on 14th March 2019
Model Y long-range RWD has 373 miles range for just £47k. Unlike M3, MY RWD gets all the interior features including full speaker setup. Only thing missing is front fog lights and the dual-motor badge. Really spacious EV with backing of supercharger network and true range well over 300 miles in any UK weather, all for £47k. This is unbeatable value. Of course, in 2 years time this will be the spec to get for £25k-30k.

the truth about electric cars
Look again at the post you quoted was to which was replying, it is a post you "liked", presumably read. (may be I'm placing too much faith in your memory) The undeniable truth is that we have zero coal power source started 5 days ago. Also, there is far less demand overnight where most EV are charging, whilst wind/nuclear are not generating less overnight. There is a huge difference between being completely reliant on far away foreign powers with vastly different political views, or partially reliant on our closest neighbours. It's like the B word, which makes more trading sense: trading with a giant economical powerhouse next to us, or trade with countries at other side of the world?

Funnily with Tesla's sales number it is able to mostly cover those top 3's shortfall. Indeed. Got to remember those losses are only realised losses when selling. So don't sell the asset during a surplus. Supply and demand 101. But with ratcheting mandate like ZEV mandate, I'm not sure there will ever be a shortage of ZEV..........

the truth about electric cars
Indeed. https://www.theguardian.com/environment/2024/oct/04/carmakers-ramp-up-pressure-on-chancellor-for-ev-sales-subsidies The part I have trouble believing is the £2 billion of discounting required to meet this target; they have sold something like 200,000EVs year-to-date, so are they really loosing £10k per vehicle? Is it at all possible because they are overpriced by £10k to start with? Who would have thought cheaper cars like EC3, EV3, Inster are the right way to gain sales volume. The brands shouting the loudest: BMW, Ford, JLR are the brands who are falling behind because they are only selling bloated SUV to begin with. EV's are hitting the volume segment, manufacturers who complain are those who got caught with their pants down.

the truth about electric cars
Lake district to Chelmsford is just over 300 miles according to Google, and should take 5 hours to drive. https://www.google.co.uk/maps/dir/Lake+District+National+Park/Chelmsford/@53.0714397,-3.9283109,769207m It would take less than 15 minutes to top up at any of the numerous service stations with rapid charging hubs along the way. Assuming did not start with full battery. Perfectly reasonable to take a 15 min comfort break in a 5+ hour drive. Apologies, got my numbers mixed up. I meant 4 hours for 250 miles, 60mph average. 267 miles in 4 hours = 67 mph average speed. Considering single lane country lanes have 60mph speed limit, it is no way achievable within legal speed limit. 502 miles in 8 hours = 62 mph average speed is about right. Hence 60 mph average is generally considered normal for majority motorway journey, slower on slower roads. I used to regularly do North Somerset to North London, with zero congestion (eg. during COVID lockdown as essential worker, I needed to be in the office and all the road was essentially empty) the absolute best I managed was 62 mph average on the Skoda trip computer when entering M25, of course dropped to low 50's once got home. Less than 2 miles of country road before joining M5 on the other side. Hence 60 mph average is about right in UK. The idea that EV battery die quicker when driving on motorway was true for Nissan Leaf. But I don't think it's true for modern EV's with good aero. Of course roof box and towing has negative impact on the efficiency, depending on amount of additional drag.

Problems at Gridserve?
From last few price changes over last 12 months or so, I feel Tesla price changes are slightly ahead of Ofgem price-cap. They dropped their rates a few months before price cap dropping, they have now increased slightly just before price-cap raise 10%. No comment on whether we are being ripped off, that's beyond my pay-grade and I can only offer similar gut feeling. I do know my extended family member from California told me 7p/kWh is very cheap.

the truth about electric cars
Trick is making it really easy to plug in. Install a holster for the plug next to where the car's charge port, so plugging in/unplug takes 1 second. Do you drive more than 250 miles in one sitting without stopping? In UK with the state of roads and without traffic, that is ~6 hours driving on the motorway. Driving up from London to Carlisle, I have only used the upper 50% of its battery capacity.

Problems at Gridserve?
Non-Tesla price seems to be location dependent now, probably them trying to manage demand. Tottenham is always almost fully utilised by taxi's. It is now 80p/kWh off peak but just 39p/kWh at same time for Tesla or those with membership. Whereas Uxbridge goes as cheap as 30p/kWh (non-Tesla) vs 24p/kWh (Tesla). There is currently an upward pressure in electricity price in recent months, so prices are going up. Tesla supercharger prices are like petrol prices goes up/down and also changes due to wholesale price change throughout the day, whereas most other CPO prices are flat across the nation and rarely change, like price-capped household electricity. The only change (price-wise, for end user) I can see is when they update their backend systems and start dynamic pricing throughout the day and location dependent. Building rapid charging hubs require huge cap-ex and rapid charging is just not the right way to recharge EV's on a daily basis. As such, I personally think only truly viable business model for rapid charging CPO is something like Electric Highway. But under Ecotricity repairs and further expansion didn't keep up. Gridserve has the capital backing and is doing something similar to Tesla, getting the grid connections done and getting those hubs build as quickly as possible, it's basically land/grid capacity grab. Gridserve are also adding batteries to their sites to serve the grid ;). So I think even when financial backings dries up, they will still able to live off selling their grid service for a while before selling off poorly utilised service station lands.
