EVs are a hard sell. Range anxiety is not an issue, but the charging infrastructure is. The cost is also too high for the average buyer at this time.
Its funny how the EU is now 'investigating subsidies' in China. China has been building this sector for like 30 years. While Europeans were so proud of their diesel vehicles and how clean they were and the Germany companies endlessly talking about hydrogen and green fuels. While Europe has basically no resource extraction related to batteries or much of any battery refinement for most of that period. But now that thi…
Traditional automakers largely got trapped in the innovator's dilemma. China had no attachment to ICE technology and skipped straight to BEV. Dieselgate was a blessing to VW because it forced them to discuss BEVs to save face. Europe leads the world in legislation and regulation, both good and bad. Their labor laws are the strongest in the world. Manufacturing in Europe can't compete on price, and the price disparity…
In reality, China's BEV strategy is going to be disrupted and will be wiped out. It is pursuing a dead end technology that few people want. It will only take a zero emissions technology that costs a lot less to finish off their BEV strategy.
Who is buying a new car these days anyway? Maybe the older generation who are living in their cheap paid off homes. But i dont know anyone below 50 who ever bought a new car. 50k for a small refrigerator? Compared to a 10 year old bigger car for 15k with similar operating costs and no hassle.
I bought a new car in April of 2020 and it was a screaming deal. Paid 3k under MSRP for a prestige trim and the total price was in the 20s. Maybe your friends just don't know a buying opportunity when it comes around?

> If you charge and discharge a lithium ion cell from 4.2V to 2.75V, you might get 250 full cycles. If you stop charging at 4V and call that 100%, and stop discharging at 3.2V, you might get 2000 cycles before capacity is reduced. Is there literally an almost 10x difference in the number of full cycles? Where can I read more about this?
The top end charge voltage is particularly sensitive, this is the most chemically unstable state of the cell charge cycle. I really wish cell phones and computers came with an adjustment to max cell voltage. Cutting even 10% capacity can double your cycle life. Some do, but it's a hodgepodge and not standard. https://batteryuniversity.com/article/bu-808-how-to-prolong-...
Having said that, this resource does not seem to support the magnitude of the numbers in LeifCarrotson's comment that I was replying to. First, I did not see a relationship between voltage and Depth of Discharge (seems unlikely to be linear, especially given table 4), which is what the page seems to mostly talk about. Second, comparing 4.2V to 4.0V in table 4 suggests a 4x difference in the number of cycles, not a ~10x difference. Figure 6 also seems relevant and suggests maybe a 2x difference.

Your last sentence is interesting. Nurses make 2-3 times as much as (K-12) teachers in the USA
The comparison here is so vague as to be useless. There are 4 categories of nurse, and I can assure you that A) a CNA and RN (let alone an APRN) are very different jobs with different requirements and wage/salary brackets and that B) K-12 wages and requirements also vary drastically. A CNA (the second most common "nurse") most assuredly does not earn more than the average High School teacher, let alone one with any s…
What most people mean by 'nurse' is an RN (registered nurse)

Thanks for the link. It is not clear to me if the resource is geared towards cell phone batteries or if it also applies to EV batteries, but I wouldn't be surprised if the trends apply to larger batteries as well.

Pull 4x from one table and 2-3x from another and it would probably put you somewhere in the 10x range. Though I'm not sure it would be strictly multiplicative.

China is imposing a government mandate on its car industry. It is a top-down solution that is reminiscence of the Soviet Union. If you actually looked closely, you'll that there is a mountain of question businesses tried to extract subsidies from the government.

Its funny how the EU is now 'investigating subsidies' in China. There is nothing "new" here. The EU warned against China's "funny" NEV policies back in 2018 -- see the EU's WTO complaint WT/DS549, "China — Certain Measures on the Transfer of Technology." You could also tell that Biden's response (aka, the IRA, enacted in 2022) to clean energy was inspired by and modeled on China's "funny" NEV policies -- ensuring tha…
And Europe has plenty of subsidies for their car industry, with the car industry being politically powerful.
> if China had so much time to build the sector.
Because its not just about cars, its everything from mine to the battery. And their policies weren't that anti-competitive, European and US car makers made a lot of money in China for quite a while and they didn't transfer much EV technology.
> let China pollute their land, air, water for clean energy!
Or lets actually take responsibility for the policy we have and act accordingly.

I don't believe anyone with a brain ever thought hydrogen was going to be practical for cars. Governments (thankfully not the US much) pushed hydrogen as a stalling tactic knowing it would never be viable or reduce demand for fossil fuels.
You are just being brainwashed by BEV propaganda. Not only do people with a brain still believe in hydrogen for cars, that includes the majority of automotive engineers. BEVs are the weird, government mandated BS cars that few people want. If the car industry was given a democratic choice, it will pivot to hydrogen as the future.
That is hilariously untrue. Even compared to your usual nonsense.
> If the car industry was given a democratic choice, it will pivot to hydrogen as the future.
In Germany the govenrment wanted to enact more pro-hydrogen polices and the car makers literally told them not to it was a waste of time.
And of course we had many periods, in the US, Europe and Japan where hydrogen was favored and pushed by the govenrment and a grand total of nothing came from it. The German government has spent 100s of millions on hydrogen cars alone, let alone other hydrogen projects. I don't even want to know how much Japan spent.
Reality is many of the subsidies world wide are not for BEV specifically but apply to lots of zero emission vehicles. You simply can't deal with the reality that hydrogen vehicles are pointless nonsense that no sane person would ever try push and BEV have trounced them in every way imaginable.
So lets see what all the hydrogen subsidies and clean vehicle subsidies have amount to:

But that was from 2020, so you say that Hydrogen cars must have pickup up since then:
> Sales of Fuel Cell Vehicles (FCEV) in the light vehicle sector have declined by -25 % so far and stay below 20 000 units annually. Current sales are from 5 vehicle models and most sales are in South Korea and USA. We estimate their current population to ca 60 000 units.
and
> BEVs reaching 10 million units
But I'm sure the 10 million vs 20k is totally just government subsidies.
It really takes next level delusion to think hydorgen cars are the future. Even pretty much all the former pro hydrogen car makers have given up. Its positively laughable that you keep believing in this.
