Thread: EV general discussion

You were saying????

Ouch!

Does VW still have any money to pay for this? And will shipping companies keep carrying EVs? Insurers keep underwriting them?

Perhaps I am missing something, the hype-train no doubt, but aren't solid-state batteries STILL just lithium, but with a solid electrolyte? I guess they will do less of the explody thing and yes they might have a higher energy density as well but It still requires the same massive amount of lithium... that we don't have and are not going to have for the foreseeable future.

This new battery still does nothing (not much) to solve the problem of producing all that stuff in time? Also, it does very little to nothing concerning the environmental impacts of using lithium.

-P

Indeed. And the "advantages" seem to be less capacity loss per cycle. So, your fuel tank still gets smaller, only not quite so fast. Oh, and reportedly reduced fire risk... I'm not jumping for joy yet. Neither are the kids chained to the mines.

Two bits of news. First in new school using the current flawed battery tech.
2024 Range Rover Electric teased as pre-orders open

800V architecture, 850mm wading depth, V8-like performance and silent drive confirmed for first Range Rover EV Jaguar Land Rover (JLR) Australia has started taking pre-orders for the upcoming 2024 Range Rover Electric as the first pre-production prototypes hit the road for real-world testing.
Underpinned by the Modular Longitudinal Architecture (MLA platform), the Range Rover Electric is said to be the “quietest and most refined Range Rover ever created” and it will offer similar performance and off-road capability to the established V8 variants.
A key component of the real-world development will be extreme weather testing in Sweden and Dubai, where the big luxury off-roader will be subject to temperatures approaching -40 degrees at one end of the scale and up to 50 degrees at the other.
Engineers say they’re eager to ensure the “robustness of the electric drive system, including its underfloor, battery durability, chassis integrity and vehicle dynamics” can survive in even the most extreme climates and conditions.

Oder NOT placed untill news 2 gets into them

Second is WIDE and game changing coming for me to tow my boat and soon to add caravan paid for via investments in this tech.

Hit a 350kWh charger yesterday. It would in 5 minutes give 400km range when I have my quantumscape, SDI, CYTAL or Panasonic solid states My MG is old school tec and could only take 150kWh. A quick phone call had it charged over 50% in Taylors lake. I had just driven from Port Fairy to Ballarat and did need a little kick to get home.


SDI 2027Battery heavyweights reaffirm commitment to solid-state technology

Only weeks after Chinese battery and car manufacturers united as part of a government-led initiative to commercialize solid-state battery technology, South Korea’s Samsung SDI has confirmed its readiness to start mass production of its all-solid-state battery technology with an energy density of 900 Wh/L South Korea’s Samsung SDI is moving toward mass production of its all-solid-state battery technology with an energy density of 900 Wh/L. This week, the company is unveiling a technology roadmap at the InterBattery show in Seoul.
The document will demonstrate that every aspect of its plan for mass producing all solid-state batteries in 2027 is well on track, from development production line project launch to supply chain management, Samsung SDI said in a statement. link





According to remarks from Gill Pratt, Toyota's chief scientist and head of the Toyota Research Institute, we're going to see such a battery from the automaker by 2025.


From SDI Link "CATL, BYD and Toyota, Samsung’s solid-state technology is based on sulfide-based solid electrolytes, which have the highest lithium ion conductivity compared to other solid state electrolytes. All solid-state batteries developed by Samsung SDI stand out for their anode-less configuration which is said to offer improved performance compared to devices featuring lithium metal anode and solid electrolyte."



3rd bit may suggest the decline of EV is over blown The American electric vehicle (EV) sector is undergoing a significant transformation. Recent trends indicate concerns about a potential slowdown in EV adoption, but the reality is quite the opposite. EV sales have reached historic milestones, with the data reflecting a natural progression toward market maturity—not a stall.
In the third quarter of 2023, electric and plug-in hybrid vehicle sales in the U.S. showcased the strongest year-on-year growth since late 2021 and maintained a robust 60% annual growth rate over the past six quarters. This culminated in a historic moment in 2023: U.S. BEV car sales exceeded 1 million sales in a single year for the first time.

More energy, 1/3 size and weight. I could be wrong of course. Only a trillion or two investments in this tech over the last ten years


Silicon/Graphite anode is a maybe. Hazer graphite ??? 2025!

So with just over 1% of the vehicles on the road in the USA being EV’s they’re reaching market maturity? Hmmm.

I think the quote was “a natural progression toward market maturity”.

Market maturity is when sales reach equilibrium and the rate of growth is minimal. With EV sales at 7-8% of new cars in the US, I can imagine EV’s to hit equilibrium in the US at around 20% in the next 5-10 years.

By then this would be a mature market for the US - at least for the next 10-20 years or so, and would fall short of the projections of 30% by 2030. California will be the exception to this and is well on track to exceed 30% of sales before 2030.

Hybrids are the market which is showing the most growth and has a way to go before it too starts to approach market maturity. For EVs to surpass the sales of PHEVs will need a major shift in battery technology, which may happen sooner than we think.

I do agree though that there is "never" (as in not before I am eligible for my pension) going to be enough resources to get 100% electric vehicles on the road usefully. The power grid in my very western, very densely populated and very modern country has never bee so unreliable in my living memory and prices have never been this high (accounting for inflation).

As an aside, I do not get it really. We have all been forced out of the most recyclable light source (incandescent) to bloody LED's which use around a tenth of the power so we should have massive amounts of power surplus but in stead we are all bouncing into the power stations rev-limiters?

As for driving less. The government down here is completely incompetent, as they all are, since during covid it was proven that working from home is feasible at least for a large group of workers. But, covid rules are gone and the traffic jams are through the roof once again. I would think with more people working from home there would be less traffic and indeed, IF Co2 is your greatest concern somehow then make people travel less. Not by limiting their movement but by fining business if they let their workers drive to a location where they do not NEED to be. It seems that many a company just wants everyone back in their fancy office which is on an expensive location where it does not need to be, in the middle of a city where parking is impossible etc etc. I the employee do not have any power over that. I reckon that would do WAY more than just pushing that EV stuff.

Lets see how it goes doing the Darian Gap one day, like the good olde boys did way back.

Aah, an incentive! Belt and Road, anyone?
