?? My point is that slow AC charging is not a barrier to entry. It is mitigated by infrastructure on the rare chance one isn't prepared. My point is that EV is suitable for almost everyone who can plug in at home. There will always be edge cases, but it's suitable for most people.

Love it. I saw this sketch recently, and reminded of recent talking point regarding forgetful politicians on climate change. t

Home charging is easy and very convenient. Do it every day, people call it graze charging. Every morning I wake up with guaranteed 50% battery or a suitable amount more depend on my plans for the day. But the case I raised is if arriving home one late afternoon with 25 miles left. No plans to go out and the car is to be slowly charged up overnight. But an emergency happened at 6pm and must imminently go 200 miles somewhere (highly unlikely, just like the need to drive 600 miles non-stop people often quote). In this instance, people often quote EV slower overnight charging as barrier and why it's not useful. I'm pointing out that around London and surround area, unplanned journey is no problem at all. Similar to your ICE vehicle, unplanned journey may need a top up along the way. Difference is, for every other normal every-day use, EV doesn't need to visit public infrastructure.

If you think of cars as luxury items rather than necessity for getting about, it would make sense. There wasn't large amount of cars to begin with. So with much lower running cost combined with sort of people able to afford cars, thus having space for private charging, it makes perfect sense. Ultimately, UK need to abolish the idea that reducing cars != less people. Getting about != driving. I'm saddened to read Oxford's anti-misinformation statements and similar misinformation statements people came up with for ULEZ (more recently London Mayor election): https://www.oxford.gov.uk/news/article/881/joint-statement-from-oxfordshire-county-council-and-oxford-city-council-on-oxford-s-traffic-filters

I called CPS on 3 May, got refund through on 9th. Then yesterday, someone finally looked at my Email that was sent on 25th. The Email didn't quote my later Email, so I guess their system just looks at one Email at a time, chasing Emails are looked at separately, wasting more time. Down here, London and surround area, public charging infrastructure is not so bad. Hubs appearing everywhere: a Osprey hub just 5min away from my parents in Welwyn Garden City. There's also a huge Gridserve hub being constructed at the A1M Stevenage junction. Luton now has 16 Tesla V4 open-to-all. South Mimm service now have 60+ DC rapid chargers. I can keep just 25 miles in my MY (10%) and drive in any direction able to reliably quickly charge up. IF emergency happened after draining the battery earlier in the day. It's not too dissimilar to unplanned emergency in ICE car. Of course, difference is in the morning there will be more than enough charge to not need using public infrastructure.

Indeed, perhaps also a public information campaign on difference between en-route rapid charging and AC destination charging. There's a lot of low hanging fruit, easy-win right now. People with driveway can charge at home but not getting EV's.

https://cleantechnica.com/2024/05/13/ethiopia-shows-us-just-how-fast-the-transition-to-electric-mobility-can-happen-in-africa/ 10% of all cars in Ethiopia is now an EV. I think the previously mentioned ICE ban was only a few months ago. So people were buying EV's before the ban came in. When the economic works, people will adopt themselves. UK could do with public information campaign on EV home charging cheapness.

Just charge at home as much as possible. It's easy and it's convenient. 50% home charging 22p, 50% charging 55p works out about similar to petrol. As I do pretty much all of my miles via home charging at 7.5p, it's super cheap. Drove 96 miles on Sunday, recharge used 29 kWh (inc AC for cabin overheat protect, sentry mode), £2.22.

Ah yes. You are right. I confused mild with full hybrid. I was thinking of full hybrid.

EV emission analysis typically use grid power mix averaged per kWh emission figure, which includes generation. For renewables it is non zero because the figure averages manufacturing and installation across usable lifetime. I wonder if those petrol/diesel emission figures include extraction, refining and transportation of the fuel...... ? If not, why not? Regarding MHEV driving on electric power. It can move short distance at low speed on electric. That's how they get better fuel economy than pure ICE vehicles and that's why all new vehicles really should have this magical addon to help reduce fuel consumption. The manufacturer's response is actually saying where the power comes from. 100% of it comes from ICE burning fossil fuel. It is not saying the vehicle is incapable of moving on battery power.

Exactly, it's a comparison tool. To suggest possible law suits for not achieving rated consumption/range is also ...........

There were talks of cars not hitting economy figures provided by manufacturer. It was said that claimed range "not being achievable". This person drove MG4 long range 292 miles with 9% to spare, averaged 38 mph including congestion in central London: https://www.speakev.com/threads/mg4-beats-its-range-estimates-yet-again.184816/ MG4 long range is quoted to have 280 miles WLTP range: https://ev-database.org/uk/car/1708/MG-MG4-EV-Long-Range

Booooo, dealer/deals trickery. Thanks for the update. Looks like £19-20k is around asking for Leaf Tekna at the moment. £15k was a bit too good to be true. Worth waiting a bit longer, see if any manufacturer panics and do a fire sale later this year when they realise they can't meet the 22% ZEV mandate.

https://www.autotrader.co.uk/car-details/202405069428886?sort=price-asc&advertising-location=at_cars&fuel-type=Electric&make=&fromsra 2013 Leaf 24 kWh, 180k miles on the clock, 11 years old. Averaged 45 miles every single of those 365 days 11 years. Although "EXHAUST AND MECHANICS ALL IN GOOD WORKING ORDER. No Funny Noises. Smooth Gear Change." not sure the seller has tailored their sales patter for the EV market. It will still work well for many people, my family included, as second car local runabouts. Oh yes, that's why we got one 😁

Always good to double check motive behind sources. But I honestly don't see any bias from someone whose job is to analyse and combat mis-information: Why is the act of identifying and pointing out clear wrong facts and mis-information considered biased? When have publishing wrong facts and deliberately write mis-information come to be considered a valid side of argument?

Nice one. Always good to get more use out of stuff rather than disposing it to landfill.

Same for oil mining on sacred land, just doesn't make as big news. Quick google comes up 2 in the last 12 months: https://news.mongabay.com/2023/07/on-indonesias-seram-island-a-massive-oil-find-lies-beneath-sacred-land/ https://thehill.com/opinion/energy-environment/4194271-dont-sacrifice-sacred-lands-to-the-oil-industry/

Population decline is coming in this decade. It has already started with some countries. Just because not all battery material supply lines are established, ethical and eco-friendly mined today, does not mean it will stay like that. Just because we do have established supply lines for oil mining does not mean it started out to be ethical, 100+ years ago. In fact, there's still many flair ups with oil mining that is hugely damaging on a different magnitude than mining for battery materials: https://en.wikipedia.org/wiki/Environmental_impact_of_war#Gulf_War_and_Iraq_War https://en.wikipedia.org/wiki/Deepwater_Horizon_oil_spill#Environmental_impact Imagine if oil were a recyclable resource that isn't consumed when used. I think in such world, the above 2 events wouldn't happen because after 100+ years of mining this recyclable resource, we wouldn't need to go to war or continue mining at such a large scale. Whenever talking about battery material mining problems, need to remember we are comparing to 100+ years old established industry that cannot be allowed to continue due to climate change.

So in summary: car fire and mining. As I pointed out, unlike consumption of fossil fuel. Mining pollution will be a temporary problem until there is enough battery to be recycled to build up circular economy. https://rmi.org/battery-circular-economy-initiative Car fire are devastating whatever the source. But data so far have proven that chance of self-ignition, probability is much lower than ICE vehicles. Also, pollution from car fire events are a tiny drop in the bucket of transportation pollutions.

My neighbour got a X1 PHEV and plug it in at home all the time. They do very local journey most of the time, transporting stuff for kids birthday party as entertainer. Car also used for odd road trips. These type of driving fits current type of PHEV nicely. Their previous Euro 5 diesel only done ~30k miles in 9-10 years when they swapped to the X1 PHEV before ULEZ expansion came into force. But apart from that particular use-case, PHEV doesn't work very well if need to drive longer distance daily. I need to commute 60 miles a day, 30 miles PHEV that is usually 20 miles is completely useless to me. edit: CTRL + Enter submits a post.

This is why I feel it's important for PHEV to ditch reliance on ICE, make it an EV first and ICE only as backup. It's not 2010's anymore. Today's PHEV architecture should now be similar to i3 REx.

What variable is there that might present itself? People are working on scaling up recycling battery, battery production can already use recycled material. We would have moved away from consuming single use mined material to a circular economy. During use, it doesn't produce more emissions of any type than equivalent (similar size weight) ICE vehicle it replaced. Its fuel can come from 100% renewable. As direct replacement, it's the golden ticket. As overall solution to transportation, there is better solutions than private transport.

Best ICE are said to be 40% efficient at converting chemical power to kinetic. That's 60% wasted, mostly in heat. Perfect for cabin heating in winter. But everytime you look at an ICE car front grill, the large radiator is a giant reminder how inefficient it is. EV are generally 80% or more efficient. Let's be pessimistic and say there's 10% wasted energy, if motorway driving and need 20 kW of power, that's 2 kW of waste heat for cabin heating. 2 kW of heat is way more than what's needed for the cabin of the car. Problem is, some EV simply dump the heat outside, such as Nissan Leaf. Every EV need a heat scavenger system such as this: (note how it isn't dumping any heat outside via radiator)

Unlike petrol to diesel, this change isn't a minor iteration on burning stuff. EV (green hydrogen FCEV or BEV) are a complete step change, completely centralised pollution, making it easier to clean up for the government. No more waiting 15 years for the car to be off the road. The only way BEV is not the golden ticket is when private transportation is being phased out. May not be in my lifetime but I think it's definitely a "when", not "if". I've been playing a little game called "Beecarbonize" https://en.wikipedia.org/wiki/Beecarbonize The best approach has always been to remove 20th centry industry and go all in on renewable as quickly as possible. EV is part of the renewable solution. For example, today had been very sunny, my solar PV generated 12.6 kWh, 5.8 kWh went into batteries. When Leaf was reaching high SoC, I set the MY to charge, 2.3 kWh during most sunny period. The evening click&collect was 100% renewable, also current house usage is 100% renewable without needing to manufacture a new battery to achieve it. Is this in worst weather or lifetime average? My old Octavia is said to be 62 mpg: https://www.parkers.co.uk/skoda/octavia/hatchback-2013/20-tdi-cr-elegance-5d-dsg/specs/ I get 53.4 mpg over my whole ownership, tracked by fuelly: https://www.fuelly.com/car/skoda/octavia/2013/wuyanxu/623258 But definitely cannot hit 50 mpg during winter. 20% deficiency. We've seen MY LR efficiency between 223-272 Wh/mi. https://ev-database.org/uk/car/1619/Tesla-Model-Y-Long-Range-Dual-Motor My lifetime efficiency in the MYLR over 14k miles is 272 Wh/mi according to the car's lifetime trip meter that I've never reset. End of the day, I've never expected to get more than 600 miles out of Octavia, despite spec claims 682 miles. Similarly, I wouldn't fault my current MY LR if it fails to reach 330 miles claimed range. But the tech inside and vertical integration with superchargers (and ability to charge at home) makes it MUCH easier to utilise the full range if needed.

It's waaaaaay too big. The pick-up bed seems like never ends. photos:
