Waerloga has different adaptors when traveling with his EV motorbike....and for both van and bike, 9 different cards for topping up in England...1 in Scotland....3 for the whole of Europe...

there's some madness in the charging market right now.
I expect that will take at least 5 years to resolve.

If Scotland ( and I think Wales ) have got it down to one card , should it take that long for England to follow?

I've got two apps on my phone, one specifically for the company that we get free rapid charging for another 10 months or so (promo deal with the car purchase) and another that seems to be cross compatible with most every EV charging station I come across.

I expect that like computers, it will sort itself out. In the early days of desk top computers, one make of computer wouldn't 'talk' to printers, or anything else belonging to another make. Now virtually all are interchangeable.

Battery claims
The following link is to the complete list of claims I have been compiling.

https://martindavidwalker.blogspot.com/2024/09/battery-claims.html

The new claims in the last week are as follows.
June 27th 2025, GM working on three new battery technologies
GM are working on Solid-state state, Sodium and Lithium Manganese Rich batteries. All of that has been reported previously but it does emphasise that not only do they recognise the future is in batteries but also the importance of vertical integration.
I'm happy to be corrected but 5 years ago it felt to me like legacy auto were having to scrabble around for batteries probably paying through the nose for the worst batteries.

June 27th 2025, Vanadium Redox Flow batteries for grid storage
Less an claim and more an â€œinformationalâ€ that there are lots of alternatives to Lithium when it comes to grid storage. All batteries have specific properties and the super power of Vanadium Redox Flow batteries is long term storage.

June 27th 2025, longer life Zinc ion batteries
Claims of a 5000 cycle life and hence a contender for grid storage.

June 24th 2025, Quantumscape speeds up solid-state production
These are lithium metal solid-state batteries entering an advanced sampling phase. Based on earlier press releases these would be 300wh/kg energy density.

at least a few of the options will become useful

The new claims in the last week are as follows.
July 5th 2025, Chery backed company samples solid-state batteries
This again is a â€œwe have a production lineâ€ claim with promises of progressing from 300wh/kg to 400wh/kg and then to 500wh/kg. Assuming accessible costs any of these numbers would be game changing.
A note on solid-state costs. I don't think it serves the interests of companies to not suggest initial prices will be high. Would CATL really want to say that in a couple of years you can have a 80kwh solid-state battery for the price of a 50kwh lithium ion battery now? They are not going to say that! But obviously raw materials costs would have likely reduced.

The new claims in the last week are as follows.
July 23rd 2025, Farasis setting up production to start sampling solid-state batteries by the end of 2025
The batteries are claimed to be 400wh/kg.
At this point to be a solid-state sceptic means you think at least 7 companies are just spouting hyperbole.

Part of me feels compelled to jump for another EV to replace my 2010 daily driver.
Currently seeing the end to a federal $7,500 tax credit, and who knows how long I could continue to expect the opportunity to be able to double that with a state rebate, AND the new tax law over here makes auto loan interest deductible from above the line income for federal taxes for the next few years (yes, our tax system is dumb, and fraught with odd incentives and complications).

But even with all of that, a new car (EV or ICE) is still quite an expense. I can probably keep my current car going another couple years before the rust and repairs make it completely untenable, but I'm not sure if the new battery tech will have brought EV prices down enough by then to make that the better choice.....

whilst the battery is a significant expense, it's now far from being the massive factor it once was, so further battery price reductions won't drive down costs massively.
I strongly suspect that in most the world production price parity has already happened.
There are afterall sub $10,000 halfway decent EVs in China.
What will change is ranges increasingly being what people need and the self driving tech ramping massively.
In three years time that is going to be the decision people have to make rather than worrying about battery type.

The new claims in the last week are as follows.
August 8th 2025, A second life for EV batteries
It's been slow on the new battery development news front, so how about some old batteries?
Cheap grid storage is crucial to eliminating fossil fuel from electricity generation and old EV batteries can play a role.
Personally I don't think it's a vital role. I think sodium batteries are going to start ramping up massively and will be common place in houses in just a few years.

August 6th 2025, AI discovers potential battery materials
Normally I stay away from lab experiments and this is barely even in the lab. However AI and materials science is an area that's going to be a thing hence raising awareness of it is important.

second use of batteries is not new, it is a good idea if it can be done safely and easily, both of which seem to be planned in by the folk trying it

it might be best to try second use battery tech in an "industrial setting" before pulling the battery out of a write off car and popping it in the utility room

my comparison is historic tech using an old style lead acid car battery after it is a bit tired for turning a starter on a chilly morning or better still an almost new battery from a scrapped vehicle, it might not be short duration high current any more but it holds and releases leccy fairly well
+ solar 12V or 28V PV rig
+leccy fence kit

= a low work, low cost, long life means to have no piggies in the pumpkins or coos scratching on the mobile chook house corners

other uses for 12 and 28 V are available, a reused lighter socket and plug will run lots of stuff direct( maybe with a few bits of leccy engineering components)
an inverter is a huge energy loss but can make 230V (best to use low V kit)
for low V kit the leccy engineering is mostly off the shelf stuff, maybe a few wires and a good meter

ps no reason to not take low V to extra high V if you need to , solid state kit can get up from a 3 volts to 20 KV in a single step so long as low amps is ok, ideal for a cheap camera flash or fly swatting bat,
12V to 7000V for a leccy fence is very off the shelf kit

a decent wimshurst machine and a leyden jar is scarily good for low tech harvest and storage of extra high V with a dangeroos amperage

other daftness is available

pps i have only ever had one 20000V shock with a dangeroos amperage, after that i mended stuff sitting on a wooden stool placed in a plastic washing up bowl

it threw me across a room over a sofa and into the wall, after 15 mins i regained consciousness, and ached a lot for several months
i recon i was quite lucky to get away with that bad mistake
