There is only one reason why car companies talk about products in development and that is they want to limit sales losses to competitors.

Solid state batteries: Toyota has history of talking big on EV breakthrough, but not delivering

Hey Tombie - you will be pleased to know I actually did read that paper.

It is a good study in that it follows the same methodology that Volvo use in the Carbon Footprint report for their C40 Recharge. It also looks to align with the life cycle emissions comparison made by Mitsubishi with respect to BEV vs ICE for cars made and used in China.

But it is from 2019 and uses carbon footprint data from 2013 which is all a bit dated now. Which leads to a few problems with the assumptions they have used.

First is they appear to be using a power generation emission rate of over 1,100 gCO2e/kWh - which would be correct for brown coal power generation, but this is 80% higher than the emission rates now seen on average in China and Australia.

Second it assumes the Tesla 3 will average 26 kWh/100km - which would be a worse case usage. Real world usage is probably 40% less than this.

These two assumptions alone result in the claimed in usage emissions rate for the Tesla 3 being 2.5 times higher than what you would expect (if we assume power usage accounts for 95% of the in-use emissions), and so completely distorts the life cycle analysis.

Using an average of 18 kWh/100km and 600 gCO2e/kWh for power generation, and the Tesla 3 would have come out at a life cycle average of 195 gCO2e/km vs 322 gCO2e/km for the ICE used in the paper (or a 40% reduction over the 150,000 km).

Of course if they are using 2013 carbon footprint data, then the ICE life cycle emissions data is probably also over stated but it is very similar to what Volvo quote for the XC40 ICE (295 gCO2e/km vs 322 gCO2e/km used in the paper). So perhaps more like a 33% reduction in favour of the Tesla 3 if updating the ICE assumed values as well.

As you note, these studies are never as cut and dry as they appear as they are very much dependent on the assumptions being used, and where the power generation comes from.

Which is why both sides of the debate will always be able to come up with a study that supports their argument.

I like Taiwan "ProLogium’s solid-state battery pack is much more compact and lightweight than a standard lithium battery, which means it’s better suited for EV applications, in particular, in electric motorcycles, where batteries must be compact and lightweight. Indeed, lowering weight and increasing energy density seem like the perfect marriage when it comes to electric motorcycle batteries, but ProLogium’s claimed benefits don’t end here

At present, ProLogium’s new battery is slated to power heavy-duty machinery such as trains, boats, and other industrial vehicles. That said, testing of the battery on EVs—particularly electric cars—is slated to take place in Europe before 2023 draws to a close."+

Mercedes any one???


I do not know if this is WAFFLE- Looking now at NYSE Prologis Inc (PLD) "117.37B $usd Market cap"
Never ever take investment advice from fools like me!!!!!! I do not own any and many not!!!!!!

I do hold a little Quantumscape market cap 4.15b $usd- I said never take investment advice from

Triva I never heard of "MAHLE is a leading international development partner and supplier to the automotive industry with customers in both passenger car and commercial vehicle sectors. Founded in 1920, the technology group is working on the climate-neutral mobility of tomorrow, with a focus on the strategic areas of electrification and thermal management as well as further technology fields to reduce CO2 emissions, such as fuel cells or highly efficient combustion engines that also run on hydrogen or synthetic fuels. Today, one in every two vehicles globally is equipped with MAHLE components.
MAHLE generated sales of more than EUR 12 billion in 2022. The company is represented with approx. 72,000 employees at 152 production locations and 12 major research and development centers in more than 30 countries. (as of 31.12.2022)

Tesla Cybertruck Spotted With Calibration Equipment In California

its not pretty!

A decent wrap will fix it…..

This is interesting "(Reuters) - A group of major automakers on Wednesday said they were forming a new company to provide electric vehicle charging in the United States in a challenge to Tesla and a bid to take advantage of Biden administration subsidies.
The group includes General Motors, Stellantis, Hyundai Motor and its Kia affiliate, Honda, BMW and Mercedes Benz , brands representing about half of U.S. vehicle sales but a small share of the EV market dominated by Tesla."

Eletric Jesus will not be pleased

Wish but doubt that on the cards here yet.

EDIT- EU just topped this one with "EU Passes Law Requiring EV Fast Chargers Every 37 Miles On Major Highways

"

Who get to pay for the EU ones ?

Wow, someone’s going to make some money laying mega watts of power cables along the freeways. Cost would be bonkers expensive. All well and good mandating such thing but as you say - who’s putting their hands in their pockets to the tune of billions of euros.

It's a standard toyota playbook. Generate as much FUD as possible and hope they can persuade enough people to buy what they sell.

The problem is every new ICE vehicle on the road is with us for a long time. It's something that should be avoided where possible because we don't want to be in a place where we are paying people to scrap cars before their time.
