Can somebody advise , I need to travel to remote west wales to visit a close relative, I can find a charge point on the way at Llandovery
it’s a type 2 connector what is that.
it has only 22kw so to do the round trip 140 miles I will need to charge there for 2 hours, is there a better way?
Where are you travelling from?

I often find a 1/3rds 2/3rds strategy is best on a long journey rather than charging at my destination.

For example, I sometimes have to drive from Stevenage to Exeter. I can get to Exeter on a single charge but find it better to stop off at Cribbs Causeway in both directions for a charge and coffee.

If they live in Reading and are going to rural Northamptonshire then at what point are they entering London (except possibly using the M25 which goes around rather than through it)?
Apologies I don't know why I put Reading. I meant to say Enfield or Dagenham.

I'm all for using rail but are you seriously saying that someone living in, for example, Reading and who has to travel to rural Northamptonshire on a regular basis (to visit family) should use rail or hire a car. I'm sorry but that's ridiculous.
If I used a car a lot less I might consider the hire charge better than paying road tax and insurance. For instance my annual music festival trip.
But if I do it regularly I would soon swallow the road tax and insurance.

But the thought of not having a car available for impromptu trips puts me off. If I had an electric car I wonder if its lack of use would be unhealthy ?.

Right, that's clearer then. Like I said, Zone 1 is a place to start. Dagenham is way out in zone 5 so far less of a priority for elimination, though steps to encourage the use of alternatives should be made.

A little village just in England by 2 miles. The journey is 130 miles, no motorway, takes me 2hrs 30mins I don’t fancy 2 hours at Llandovery on the way back at 8 o’clock on a dark wet cold night, I wonder how much to allow for headlights heater etc.
and does a type 2 connector fit any car. Plus there are only 2 chargers in the town, guess they might both be in use any way

is 65p a kilowatt a reasonable price

Use ‘A better route planner’ (ABRP). It’s available as an App or website and will give the best options for your route and where to charge (if needed), based on the EV, time of day and average temperature for the date you choose.

A type 2 charger is a 'normal' charger plug like you'd have at home (i.e. not a rapid charger)

According to Zapmap there are two rapid chargers at Llandovery Castle car park. What is your exact journey as that would help to identify suitable places to charge? Whn I'm doing a long journey I try and identify at least two places to charge at so that I've got a back-up in the event of chargers being out of order, all in use etc.

That’s the problem, I’m trying to work out what sort of car I might upgrade to without spending forty odd thousand

the round trip is 260 miles so I would not like to risk it with a range less than 300 given that it is up and down hill and the twisty bit between brecon and Llandovery can be challenging at times, looks like I might need a few lottery tickets.

i can buy a bottle of milk and a loaf of bread and get 470 miles on my hybrid in five minutes at the texaco on the way

I appreciate your help but I am only planning, have not bought the car yet., but it’s a journey we do a lot, there and back in a day visit, a 2 hour charge would make it hardly worth while

Ok I see.

Try not to over think it. When you get an EV you soon get used to trusting the range, and given the massive cost differential between home charging and public charging (public charging can be more than 10 times the cost of charging at home), if you've had to use public charging on a long journey you really don't want to be getting home with more than 10% range left on the battery.

As I said upthread it's not all about charging at your destination. You might put 10 or 20% charge on the battery on your way to Llandovery. While you won't need the charge at that point it might mean you can get to your destination and back without further charge.

Time of year makes a big difference. Back in the summer my EV was giving me 320 miles range, put the aircon on and it'd drop 20-30 miles. Now it's got colder the range has dropped to 290 miles, pot the heating on and it's 260 miles.

You have to think about things a little bit differently when you have an EV.

I appreciate not everyone can charge at home, but I can and I'm looking forward to significant savings over petrol!

Where are you actually going? You may be able to charge at or near your destination.

Unless you are planning to buy a new car in the next few weeks/months there’s no point in trying to second guess things now. New charging hubs are opening every week. A new E.On 10 bay charging hub opened at Cross Hands on the A40 a couple of weeks ago. New EVs and refreshed models are frequently being released, with improved efficiency and range. If you are looking to buy in a couple of years or even next year the landscape will probably be very different.

Perhaps it’s a lifestyle thing, being both retired we tend to just go places on the spur of the moment, lets go and see a national trust garden, it’s not that far, we’ll be there for lunch, doesn’t fit in with planning a journey, most of my working life I would pick up the phone at 8 am and ask where am I going today. Could be almost anywhere depending on whose emergency was the most vital

I counter with the Nissan Leaf (iirc). One example (good or bad) does not prove anything about EVs in general. It is highly probable that EVs will improve as the technology matures - it is relatively new technology.
So you give one example. The one example that is well known to suffer degradation and other issues because there is no thermal management at all on the battery pack.
Every other EV (except the Nissan NV200 van) has a liquid cooled battery and does not suffer these issues.

It's mature technology that is still improving and getting cheaper.

I would think the battery tech needs to evolve and become less likely to explode or catch fire for EV's to really take over.
Yeah I have to wait till solid state and less flammable batteries come out. I know it’s media fuelled fear but seeing that ev fires happen and are worse than ice fires puts me off considering getting an ev. There are much less ev’s than ice cars in the road so fire stats seem a bit skewed to say ice cars are more likely to catch fire.
Not this old chestnut. To be clear, I drive a petrol car. Every so often I go to a place to replenish that car with a volatile, flammable, liquid. There are clear dangers involved with handling that liquid but they're well understood and I've been doing it for years, as have many others. That fuel then goes into a tank which could potentially rupture in a collision, but car manufacturers have assessed those risks.

The thing with an EV fire in the batteries is that it is very hard to stop the fire once it has started - it does not need oxygen. Most fires (so non-battery) are put out by starving the fire of oxygen (drowning them in Water, Powder or Carbon-Dioxide) that does not work with an EV battery.
I was taught from quite a young age that fires required three things: fuel, a source of ignition and oxygen. Could you provide a source that will convince me that EV fires do not require oxygen?

It is not just the car - it is the damage done to the surroundings.
Any car that goes up in flames is going to do damage to its surroundings.

Another route (312 iirc) has reverted to diesel and I have been told it is because the batteries were failing. Apparently they need on average £100k spent to repair each bus.
Proper evidence is required here. "My mate who knows someone who works at the bus garage" is not an acceptable source. Sorry. :)

If that's a serious question:
1: A type 2 connector (aka Mennekes) is usually a socket into which you plug your own charging cable. You say "it has only 22kW". If so, then that is a three-phase AC supply. Whether you can use three phases depends on the car. Many only accept single phase, in which case, the best rate you will get is 7kW. That adds something like 25 miles per hour (depending on the car) charging. However, I note that there are two DC rapid chargers in Llandovery (Castle Car Park) as well. These will refill your car much more quickly - maybe 150-200 miles inside an hour. Again, how quickly depends on the car. DC rapids have attached cables so you don't use your own. And, at the time of writing, another nearby unit exists, but is showing out of service.
2: No, 65p is ridiculous. But it's on the low side of average for a roadside charger. That rapid is 79p. Charge to whatever extent you can using a domestic supply at home or at the relatives for far better economy. (You only need a 13a outlet and a lot of patience, or an overnight session).

A Simple Google search.

No, EV batteries do need oxygen, but they can create their own oxygen during a thermal runaway event.

Thermal runaway
A chemical reaction that occurs when an EV battery malfunctions, producing a large amount of heat and gas in a short amount of time. This reaction doesn't require oxygen from the air to continue, and the heat from one cell can spread to the others, causing them to fail as well.

So the claim that EV batteries do not require oxygen to burn is entirely false. Thank you ;)

OK, this is more having different mindset.

Virtually all new EVs nowadays have ranges over at least 200 miles, typically nearer 250 miles, (or can spend a lot and have them with higher range over 300 miles). As a general guide work on 85% of official range in summer, 75-80% in winter. The actual figures will vary by route, temperature etc.

So generally could expect around 170-210 miles without recharging (in non long range EV). Even at motorway speeds that is about 3 hours, and maybe you feel more youthful than me, but by 3 hours I normally tend to want to stretch legs and/or go to loo. Anything over 3 hours journey and tend to need this pause anyway.

It is true many towns only have one or two lowish power chargers, but in last few months banks of 10+ medium-rapid chargers have been springing up at many good stopping places. As an example a local farm shop & cafe is currently installing row of chargers for about 12 spaces. Likely to be many more of these in next few months. (And seeing as you mentioned National Trust some of their car parks now have chargers, and guessing more will follow)

Remember you might only need to add 40 miles range to comfortably complete your round trip, so don't get in mindset you need to find a charger that can completely charge it (which might be different idea to if you go to petrol station you completely fill car, rather than put in few pounds worth to get you home)

Indeed. I almost never charge to 80% out and about unless I'm away from home for days. There's no point arriving home, where I can charge for almost nothing, with lots of expensive electricity in the battery.

If the government wants to encourage EV adoption, why don't they regulate the cost of charging?
I think the assumption is market will find a competitive price longer term.

And if you regulate price now then won't be any incentive to install chargers because can't recover (or will take long time) for installation costs to be recouped

Petrol has its risks and really ought to be more risky than EV batteries. But once an EV battery is "burning" not much can stop it until it runs out of energy.
I was taught from quite a young age that fires required three things: fuel, a source of ignition and oxygen. Could you provide a source that will convince me that EV fires do not require oxygen?
Unfortunately the battery can create all it needs to "burn". Once it has broken down then the huge amount of energy is off on an uncontrollable thermal spree.
Any car that goes up in flames is going to do damage to its surroundings.
But an EV will keep "burning" whereas an ICE car fire can be brought under control and extinguished.
Proper evidence is required here. "My mate who knows someone who works at the bus garage" is not an acceptable source. Sorry. :)
Well we will have to agree to disagree on that one. I know for sure that two routes in Croydon that used electric busses have reverted to diesel.

Thankyou. In effect once that battery or part of the pack has gone into thermal runaway then all the fire brigade can do is stop the fire spreading to surrounding buildings and cars. Effectively have to wait and monitor until all the energy in the battery has been dissipated.

Surely you can see that the proportion of electric buses in London is increasing all the time? Croydon has more routes run by EVs than many other areas in the UK. Most of the UK still don't have any. The 64 was converted to EVs only a few weeks ago.

Look at the electric bus rollout in the Netherlands. They have been buying almost if not totally electric buses for a number of years now.

Because if they did so no new chargers would be provided. The cost of providing and maintaining the infrastructure plus the back up support is very high. The problem is that people are looking at the EV headline tariffs provided by the likes of Octopus without realising that the energy suppliers are actually losing money on those tariffs and subsidizing them from other areas. In 5 years time there's no way you will be paying 7p/kwh to charge an EV even overnight.

If Octopus are losing money on it I don’t think they would have reduced the price from 7.5p to 7p a few months back! Also you often get daytime slots at this price when it’s windy/sunny and there is excess power/curtailment going on!

That much is verifiable fact, - vehicle type changes on certain routes is not uncommon with large operations. Your assertion however, that the change was because of some dire issue - "batteries were failing" was offered presumably from your 'mates', is both nebulous and so far you haven't offered any reference for your claim.

Have a look at one of the grid watch sites today. It's an anti cyclone - high pressure. Renewable generation is negligible, it's been like that for several days now and will continue to be so well in to next week. Next consider the nuclear generation, 4.5 GW that will all but be gone in 5 years. (Sizewell B is currently shutdown for refuelling and for new turbines in the generators). Hinckley Point C may make up some of the slack if and it's a big if it's on time but even then it's electricity is a lot more expensive than what it replaces.
Then consider the increase in demand if even a relatively modest proportion of vehicles are converted to electric propulsion and gas boilers are converted to heat pumps. In 5 years time electric cos won't be able to offer cheap rates as an alternative to curtailment because the grid will be at max capacity.
Octopus go etc are definitely loss leaders or at best wafer thin margin products to lock in customers for much higher rates and profits in the years to come, sorry to break the bad news.

Except Octopus don't lock you in to the tariff. I could change to a different tariff tomorrow if I wanted, and back to Go a week later.
In fact some people do use Go for part of the year and Agile the other part.

It's not a loss leader, Octopus make money even on the cheap rate because they are using vehicle charging to soak up excess generation which would otherwise result in costly curtailment fees.
