the truth about electric cars
Yes, hydrogen still has its place as a niche product that caters to those that just cannot make EV work, mainly to minimise downtime. The problem is all those storage methods (home battery, pumped hydro, storage at generation sites) require additional cap-ex and thus makes renewable more expensive than necessary. Batteries for all applications are not nice to make, it is bonkers the battery in EV are not being utilised when the car is parked. Smart cloud based system have the capability to create virtual power plants or power sink with much less front cost. Smaller battery does not exclude it from being used for V2G. I'm planning to use V2H with my now 18 kWh Leaf, according to my back of envelope calculation, there's room to spare for exporting to the grid, amount depend on season and sunshine. V2G can also not drain the battery by providing grid 50Hz stabilisation. Something used to be done by big gas turbine. This V2G is done with 24 kWh eNV200's. FCEV is only slightly better than ICE when using green hydrogen. The typical diagram as to why: As long as this inefficiency is captured in the running cost, I have no problem with hydrogen FC cars. Blue is well understood to be worse than Green in terms of environmental impact. Using blue hydrogen at cheaper cost than green would be functionally the same as running petrol/diesel and not paying attention to their pollution. Hum.... sorry, I have forgot about the isolator switch. The EV charger and electrician used the isolation switch, not the fuse, I remember. I can't recall if solar company pulled my main fuse. I can recall the main fuse seal was broken after solar install. Meter inspector and smart meter installer didn't bat an eye lid.

the truth about electric cars
40 cars would only need a max of 20 EV charge points. overwhelming majority of people don’t need to recharge every day, or even every other day. But of course, more the merrier. However, being realistic, I’m not sure it’s physically possible to provide for all parking spaces. Public slow EV charge points, cable are in the car and looked after by car owner. But even my 6 years old cable left on the my home charge in rain and sun still functions like new and zero sign of wear and tear apart from discolouration from white.

the truth about electric cars
This is classic passing the buck. Any qualities electrician can pull the main fuse. I’ve had solar company, EV charger company and regular electrician pulling this fuse. The thing with slow charging is that it is parking with charging. People are not expected to move their car while parked at any destination. Same apply to slow destination chargers. People do move their car as good etiquette to others when the resource is so limited, but it’s just that, good etiquette. Stealing what exactly?

the truth about electric cars
I did, see second post of this page. Again, this demonstrates lack of flexibility in your thinking. Just as thinking need to wait hours for cars to recharge. 😂 Did you look at the link? EV ownership via public slow charging, even charging at peak period, is still cheaper than petrol. If you want to exclusively use rapid charging, some of Tesla network is open to public, with a monthly subscription, their off-peak is cheaper than public slow charging and their price decrease is even faster than domestic tariffs. As to how to solve convenience factor…… Blanket install smart slow charger for as much existing parking space as possible is the solution. Road side, any and all car park. Anywhere over 4 hours of typical dwell time is perfect for slow charging.

When slow charging, people don't "waste hours and hours waiting for a full charge".

the truth about electric cars
Why do you always take things to the very extreme? "all EV's in car parks enter thermal runaway" "to solve home charging, flatten all tower blocks, level all terraced houses" According to AA, who've forgotten about home EV tariffs, public charging is not keeping pace with residential price drops. https://www.theaa.com/about-us/newsroom/aa-ev-recharge-report-july-2023 It's similar to petrol prices, goes up quickly but comes down slowly.

the truth about electric cars
Have I glossed over the issue? Point is it’s indeed a problem need solving, it need to be solved in such a way so that everyone can contribute to the renewable energy transition. I laid out the reason why EV are critical part of the transition, how smart public slow charging can help both consumer and grid. Credit where credit is due, you didn’t mention rapid charging and same model of re-energise the vehicle is a must. Also you recognised cost benefit of able to charge at home. Let me re-iterate, I totally understand there is a have/have not gap that need addressing. And need a top-down strategy for this fast. Unfortunately this kind of “levelling the playing field” is something uk government is very bad at…….

List of EV Tariff for 2.5p/mile motoring
I know paywall and USA, but it gave a few reasons, such as vehicle "upgrade" and curiosity to test EV. https://www.wsj.com/lifestyle/travel/electric-vehicle-rentals-tesla-hertz-38ecd430 Personally, I'd want an EV for the better drive. Also I'm used to "the search". I've set arbitrary limit of about 20% extra rental cost to get EV's during family holiday. We, as family, decided Norway for next summer. So I'll be renting an EV next year. 🤞 I've made a poll on SpeakEV to see if people seek out to rent EV's: https://www.speakev.com/threads/would-you-look-to-rent-an-ev-during-family-holiday.179998/

the truth about electric cars
This completely misses the point of having batteries. Might as well throw out any cost benefits and go for expensive green hydrogen in fuel cell if you must need direct replacement. Simply take petrol station mentality across to EV charging does not make any sense what so ever. I've mentioned vehicle-2-X and smart charging many times. It is the reason why BEV are very important part of overall energy solution. Renewables generate unpredictably, BEV when parked can help here. EV ownership without driveway is indeed problematic. There's not much cost benefit and it's not convenient. There's no denying this need to be solved. But I don't think we should solve this by applying petrol station refuel mentality and demand this to be solved by asking those without driveway to rely on expensive rapid charging. Charging speed flexibility is a huge asset to the grid's renewable goals, I think this can be used to reduce public charging cost just like existing smart charging tariffs. Intelligent Octopus (IO) home tariff is a form of smart charging. There's no reason why this cannot be applied to street level charging, any location where car is likely to be parked for longer than it needs to recharge. There's leeway to tweak power draw so that demand matches supply, instead of traditionally firing up fossil fuel power stations to make supply to meet demand. Multiply this flexibility across all BEV fleet in a country, we have built a virtual hugely adjustable power demand leaver. Current smart charging tariffs: https://octopus.energy/smart/intelligent-octopus/ https://www.ovoenergy.com/electric-cars/charge-anytime In 5 years time, V2H would be mature (as in product to buy and cars to use with). That huge battery on the driveway suddenly becomes home battery. May be in 15-25 years time, most chargers will become V2G. We will have built a virtual power plant: https://en.wikipedia.org/wiki/Virtual_power_plant We got to get use to a little forward planning, having all that energy stored and not actively utilised is an expensive luxury/waste. Same as having cash under the pillow vs make them work in stocks and shares (or crypto 😛 )

the truth about electric cars
280 miles 200 miles from home charging in depth of winter, let’s be pessimistic and say 3p/mile. £6 Again, be pessimistic and add 100 miles, 25kwh at supercharger, typical price at 35p/kWh = £ 8.75 Total < £15 Of course, home charging is a luxury and pretty much a requirement for cheap EV ownership. But single charging driveway space can charge 3 cars with some planning, for multi car households. Go up to EV sun forum and see my thread on EV tariff for 2.5p/mile motoring.

List of EV Tariff for 2.5p/mile motoring
I think it's only available to those with podpoint charge points at home and with smart meter, from new posts in the thread I linked. It's also not clear if the charging is free or not. But there is a possibility other smart charge point supplier may participate. TBH this is the idea with Intelligent Octopus, only charging EV when there's higher amount of renewables. But IO is not as directly linked to renewable excess as it could have, the messaging is more focused on car usability.

the truth about electric cars
I'm comparing similar size ("mid" sized SUV) and similar power, EV against PHEV, diesel and petrol, from a range of manufacturers. Saying all are within 100kg of eachother and BEV are not actually heavier as people are lead to believe. Trying to compare a different class of car to those is neither here or there. Superb does not have 800l boot, it does not have 300 bhp power and it is a completely different style of car with less head shoulder room. I will if you do the same and don't have a go at me for posting data and facts (quoted the part that started this). Getting the fact straight is never about "defending their honour". You are always welcome to post your counter arguments using your data set or references. Also, let's set the record straight that I think hybrid on most levels are not electric vehicle, they are ICE cars with different level of electrification. Most cannot travel long enough without falling back to burning fossil fuel. So I consider 2035 to be the date for sale of new ICE ban. I only consider the i3 REx serial hybrid to be an EV. ICE must not be mechanically linked to the wheel and burning fossil fuel most be the very last resort. So apologies if I use forgot and EV and BEV interchangeably.

the truth about electric cars
I had not chosen the cars, it's result of a quick google of "heaviest cars UK". You can choose to invalidate facts based on your personal preference, but don't call facts BS when it doesn't agree with your view point. I feel compiled to post when misconception are posted. In this instance EV's are heavier. It is simply not true when the platform is designed to be EV from day one, without any associated ICE legacy elements. If you feel posting facts and attempt to correcting misconception is disrespectful...... Do you feel people should stay silent when misinformation or FUD are posted? Cos that's what you are suggesting I should do. Regardless whether what you posted is rant or not. Where have I not respected opposite views? It would be nice to have evidence to back up your statements.

the truth about electric cars
Which part of it is "pure BS"? There are 4 BEV (EQS SUV, EX90, EQS, Q8 Etron), rest contains ICE. Yes, I forgot the B in BEV. But isn't battery electric vehicle the whole point of discussion? I was talking about dedicated EV platforms. Also sorry, I mistook top 12 for top 10, but doesn't change number of BEV I counted. So 8 out of 12 heaviest car are not BEV. This conclusion based on the list I'm sure you will agree and it is actually very far from "pure BS". A lot of conformational bias and rant from you against me for just posting a link and quoting facts (only 4 out of 12 in heaviest car list are BEV). What do I have to accept when facts say otherwise? At what point have I said people should only buy EV right now? At which point have I shown disrespect to those who chose differently to me? Would you kindly quote evidence to your allegation.

Tesla Model 3 facelift
The manual is available online if anyone's interested: https://www.tesla.com/ownersmanual/model3/en_eu/ I had a quick flick through. The PRND override physical buttons are on the roof and requires pressing 2 scroll wheels to enable. They really don't want you to use physical buttons. 🤣 There is no front bumper camera. There's a new active hood, I don't remember seeing this page when reading MY manual.

the truth about electric cars
Here: https://www.campaignlive.co.uk/article/dvla-goes-gear-campaign-disrupt-vehicle-tax-evasion/1747947 Good question, dedicated EV platform are not clearly known except within EV circle. Weight isn't transparent when buying a vehicle. It is not a parameter on people's mind. Hopefully tax based on weight will put it front and centre. The multi-storey car park weight worry story singling out EV is a strange one. Remembering that there are just as heavy ICE cars. 6 out of 10 heaviest cars on sale in UK are not EV: https://www.autoexpress.co.uk/tips-advice/360607/heaviest-cars-sale

the truth about electric cars
Weight is a contributing factor to efficiency. So I favour this method, it's simple and effective. But well designed EV's are not really heavier. Tesla Model Y LR: 1986 kg, 378 bhp, 854 l boot. Tesla Model Y SUV Long Range AWD 5dr Auto specs & dimensions | Parkers Volvo XC60 polestar engineered PHEV: 2145 kg, comparable 399 bhp, 598 l boot. Volvo XC60 SUV Polestar Engineered T8 Twin Engine AWD auto 5d specs & dimensions | Parkers Audi SQ5 sportback diesel: 2010 kg, 336 bhp, 500 l boot. Audi Q5 Sportback SQ5 TDI Quattro 5dr Tiptronic specs & dimensions | Parkers VW Touareg R-line tech petrol: 1945 kg 335 bhp, comparable 810 l boot Volkswagen Touareg SUV R-Line Tech 3.0 V6 TSI 340PS 4Motion Tiptronic auto 5d specs & dimensions | Parkers Only poorly adopted platform from lazy manufacturer are heavier. For example this small EV based on their GLA platform: Mercedes EQA: 2040kg, 187 bhp, 340 litres boot https://www.parkers.co.uk/mercedes-benz/eqa/suv-2021/eqa-250-140kw-sport-665kwh-5dr-auto/specs/

the truth about electric cars
Are they ANPR cameras? https://www.police.uk/advice/advice-and-information/rs/road-safety/automatic-number-plate-recognition-anpr/ I think ANPR cameras can be used for tax purposes as you laid out. But whatever the tax scheme, one thing is important, long term EV taxation should never be more expensive to run than ICE. I can understand if EV are taxed more heavily initially to account for initial carbon emissions. But during use, EV should always be cheaper than ICE to run. The message should always be "keep this EV on the road for as long as possible".

the truth about electric cars
I personally don't like the image of growing dots, feels itchy and like insects....... On taxation. if taxing electricity, it'll get complex real fast: - Tax home charge points, people can use 3-pin domestic plug - Tax self micro generation (most common solar PV), stuns solar install and incentivise garden shed DIY solar installs - What about lol's setup with portable battery and portable solar? What about the car's integrated solar panels? - Don't tax solar, current smart meter legislation doesn't require this info to be captured. - How does V2H/V2G fit in without further complication? This is the direction we must take to hit 100% renewable, the EV parked are perfect storage devices. I think the only sensible way is to have VED based on vehicle weight. And/or per-mile duty for all vehicles.

England EV Charging points, a proposal. & location & news on new charging hubs in England & Wales.
Yes, it's both a destination and a charging hub. So it makes sense to have more 7 kW units than third of the number 22 kW units. Charge for 6 hours means can drive a fair way away before need a top up. It's like the Oxford Redbridge park and ride. There's 7 kW for parking and rapid charging for people driving on the trunk road needing en-route charging. I'm currently of the opinion that car parks should be blanketed with destination charging. In combination with ultra rapid for en-route charging if the location suits. Pretty much how it's set up at this new charging hub in Birmingham.
-
New or improved hubs announced, Government EV Loans in Scotland and free & no longer free public charging places..
Woo, they are Kempower units. It gives you a QR code to scan and you can see live charging curve. All chargers should be like this to keep user informed.

the truth about electric cars
It's funny. During day outs, I often joke to my wife that if I'm injured, she can't get home. Because after 1 year with Tesla, she still hasn't sat in the driver's seat. She's just not interested in driving. She always replies she can uber/taxi to nearest train station and get home. Not sure what my point is TBH. May be there's always options to not get stranded? I know AutoAid breakdown covers EV out-of-juice situations. Last time I had trouble rapid charging was a few years ago, I miscalculated and need a small top up in the Leaf. 1st was offline, 2nd single charger was occupied, 3rd wouldn't start. Since then, 1st location South Mimms now have 8 chargers installed, not including 12 Tesla ones. 2nd location was Shell garage down A1, now have 8 chargers. Third location, another Shell, has had charger removed. But a few min up the road there's Instavolt. The charging situation is improving at vast speed.
