Knowing the pace that Musk dictates I would love to know what else Tesla is working on or what the pipeline is. Perhaps 2-3 years ago legacy car companies could have caught up if they focused their efforts, but I think Tesla is so far ahead now they will be impossible to catch.

The biggest risk is running into cashflow issues but I believe at the last report they had about 2 years worth of capital expenses in the bank, so this is also unlikely to be an issue.

Battery day for investors will supposedly show off cells that will experience only ~10% degradation over 1 million miles of wear (roughly 83 years of driving the average 12k miles/year an American drives), while also removing as much conflict cobalt as possible from the cell chemistry. Their autobidder software used at the Hornsdale Power Reserve for utility scale storage is in the process of being extended to allow Tesla to act as a virtual utility in the UK. Components of this are used in Sweden to provide Tesla owners with low cost power to charge their vehicles based on market pricing signals from the utility (charge when the cost of electricity is low or negative).

Exciting times.

Prices go negative because it's basically a grid control service at that point. You have a load you need to have taken, and are willing to pay someone to help you manage the grid.
Re:Tesla's batteries aim to rework the math for electric car... by toomuchtodo on Thursday May 14, 2020 @01:38PM (#23182686)
It's the other way around; prices go negative because you have too much power, not enough load, and you're paying someone to take that power because you can't curtail like solar or wind (perhaps you're a gas turbine or coal/nuclear generator that must run for frequency control purposes).

Check out the Hyperchange YouTube channel it does a really really good job of following Tesla battery developments and has had a number of scoops that I haven't seen reported in the media. This article also seems to confuse Tesla's relationship with CATL and their efforts to research, develop and manufacture their own cells independent of their parties like Panasonic or CATL.

The Limiting Factor channel is even better (less marketing, more technical, with a huge focus on battery tech): https://www.youtube.com/channel/UCIFn7ONIJHyC-lMnb7Fm_jw

And for reliable general reporting on Tesla, Tesla Daily is far better than HyperChange (who's far too hyperbolizing): https://www.youtube.com/channel/UCgYkuL87rUwiBl7tqfN53Eg

> but I think Tesla is so far ahead now they will be impossible to catch

Are they really though ? You don't see Tesla being much more efficient than any other EVs so far ?

Re:Tesla's batteries aim to rework the math for electric car... by eyesee on Thursday May 14, 2020 @12:53PM (#23181961)
Actually yes, they are noticeably more efficient than other electric vehicles in their class (similar weight and range). One example shows Tesla as 20% more efficient:

Chevy Bolt: https://www.fueleconomy.gov/feg/noframes/42191.shtml

Tesla Model 3 Standard Range+: https://www.fueleconomy.gov/feg/noframes/42278.shtml

Here's a complete list: https://www.fueleconomy.gov/feg/byfuel/EV2020.shtml

Re:Tesla's batteries aim to rework the math for electric car... by semi-extrinsic on Thursday May 14, 2020 @01:26PM (#23182465)
Comparing Model 3 vs Bolt on efficiency is just aerodynamics. A lower, longer car is of course more efficient than a taller, shorter one.

The Hyundai Ioniq is a similarly shaped EV as the Model 3, and it gets very similar numbers - 133 MPGe (Ioniq) versus 141 MPGe for the best version of the Model 3 Standard Range, a difference that's smaller than going from 18 to 20 inch rims on the Model 3 Long Range Performance.

It is essentially useless to compare cars that are within 10 MPGe of each other at 130+ MPGe. If your tires are slightly off optimal pressure, or you've left something heavy in the trunk, or you've chosen different rims than standard, you've lost more than this. God forbid if you've put on a roof rack, probably drops you 30 MPGe down to 100-ish.

This discussion also underpins why MPG is a poor unit to measure efficiency with. The inverse measures used in Europe like L/100km or kWh/km are much easier to compare, as differences can be compared directly between a low and a high efficiency car

I don't think many people realize that MPG is not a linear measure of fuel/energy consumption.

https://nudges.files.wordpress.com/2008/06/mpg-graph.jpg

If an average driver (12,000mi/yr) switches from a 12 mpg car to a 15 mpg car, they save 200 gallons of gas per yr.

If someone who drives the same distance switches from a 60 mpg car to a 63 mpg car, they save 10 gallons of gas per yr.

If someone who drives the same distance switches from a 133 mpg car to a 141 mpg car, they save 5 gallons of gas per yr.

Re:Tesla's batteries aim to rework the math for electric car... by tomjakubowski on Thursday May 14, 2020 @02:28PM (#23183392)
I agree that subtraction is not especially helpful when comparing two cars fuel efficiency using MPG. A simple way to frame it is that doubling MPG halves your fuel needs for the same distance.
Re:Tesla's batteries aim to rework the math for electric car... by eyesee on Thursday May 14, 2020 @02:37PM (#23183527)
It's tough to find fair comparisons. The Ioniq for example weighs 500 lbs less than the Tesla and has significantly less range as well.

In addition to aerodynamic improvements (which is of course a non-trivial engineering effort), Tesla does have a unique rear motor design that is more efficient, an industry-leading inverter design, and many incremental engineering efforts that cumulatively save several percentage points. Because they are "all-in" on an EV design they don't have to compromise because of a shared EV/Hybrid vehicle frame design for example.

The EPA listings also provide kWh/100 miles which I use for comparison to avoid the unfair MPGe equivalency.

Re:Tesla's batteries aim to rework the math for electric car... by semi-extrinsic on Thursday May 14, 2020 @07:36PM (#23187059)
Yeah, I'm not saying the Tesla is poorly engineered. But OTOH it seems hard to argue they have some special sauce that gives them 20% advantage over everyone else. I don't see how they have a moat - partly because designs are already running close up against the fundamental physical limits e.g. in aerodynamics and power electronics.

Another example: the Hyundai Kona is a purely electric platform that doesn't need to compromise, and it matches the efficency of the Model Y.

Re:Tesla's batteries aim to rework the math for electric car... by NickM on Thursday May 14, 2020 @02:59PM (#23183823)

The Ioniq has substantially less range than the Model 3, and is a much smaller car. If the Model 3 still gets slightly better MPGe despite those differences, I'd say Tesla still has a pretty significant efficiency advantage in this comparison.

Re:Tesla's batteries aim to rework the math for electric car... by semi-extrinsic on Thursday May 14, 2020 @07:25PM (#23186910)
According to the specs on interior dimensions listed on fueleconomy.gov, the Ioniq is actually bigger - 96 cu ft passenger and 23 cu ft luggage volume, vs. 97 cu ft passenger and 15 cu ft luggage for the Model 3.

So they've sacrifised range by installing less batteries, gaining more luggage space, lower weight and lower price.

They have some advantage in technology, but so far they are just ahead, but usually not by leaps and bounds. They have the most experience with the drive train, the battery and the self driving. However the real 'moat' they have, is producing EV profitably, as far as we know, the other auto makers, at least until this year, were never making money of EVs. At least Ford/GM will probably continue like that, the new Electic Mustang on paper competes with Tesla but uses a battery twice the size, meaning that it can not be very profitable, if at all.

Tesla last Qt showed 25% margin on their cars. That is higher then most OEM get on their cars (usually its cheaper cars to be fair). Other OEM don't report the margins on their EVs, but most analysis shows that they make basically no money, and very often negative money.

Tesla is pushing on batteries like crazy and trying to vertically integrated and innovate both on the chemistry and on the packaging. Most OEM buy battery cells from the same 3 companies, and that often leads to delays for all of them. LGChem in Czech Republic had shortages and that lead to like 5 different EV being produced in numbers far bellow announcement. With every car maker claiming to massively increase EV sales, those battery companies are standing to make huge money but they will capture much of the margin as well, because the battery is like 1/3 of the cost of the car.

The next generation drive train Tesla has announced for their S, X, Cybertruck and Roadster will blow out of the water even what you can get from a 200k Porsche Tycan. Nobody else has announced anything like it. Breakdowns of Tesla shows that their cheaper drive trains are both lighter and cheaper to produce then the competition (see Sandy Monro).

In terms of Self Driving, among OEM so far as I know they are the only ones that are building their own self driving computer. They costume design their own hardware solution including their own designing their own dedicated chip and software to run on those chips. Plus, their tight fleet integration of cars that already have the sensor suited necessary allows them to query the fleet and use driver to train the network. Also, these computers are pretty cheap and light to build compared to the hardware that is in a Waymo car.

There are other things like software updates, business model innovation (no franchise dealership) that other car makers struggle with. The franchises is specially important because those dealers make their money on servicing, so they don't want to sell EVs.

All in all its fair to say that they do have a lead on a number of fronts. The competition has been catching up slowly, but mostly because they stared from nothing basically.

Re:Tesla's batteries aim to rework the math for electric car... by elihu on Thursday May 14, 2020 @02:33PM (#23183470)
I think their main advantage at this point is that they make batteries that are well over 200 watt hours per kilogram and they can make them cheap, whereas most other EV batteries are in the neighborhood of 150.

“Perhaps 2-3 years ago legacy car companies could have caught up if they focused their efforts, but I think Tesla is so far ahead now they will be impossible to catch.“

Car companies have deep pockets and catching up is always easier than going first. I can’t think of many industries where the first mover was the winner. Usually it’s the second movers who succeed and gain dominance. Tesla is still bound by the law of physics and chemistry so what they do, others can do too.

Re:Tesla's batteries aim to rework the math for electric car... by rcMgD2BwE72F on Thursday May 14, 2020 @01:54PM (#23182951)
And yet, even Volkswagen recently admitted that they only intend to follow Tesla on BEV, not lead them. Toyota has no skin in the game (they completely missed the switch to BEV), BMW and Daimler are unable to compete (even when they join force), etc.

The deep pockets of the non-electric car companies are evaporating fast nowadays, they margins keep dropping while Tesla's increase. Things are moving quickly, and far too quickly for those who couldn't change while they were massively profiting from internal combustion engines.

Re:Tesla's batteries aim to rework the math for electric car... by ntsplnkv2 on Friday May 15, 2020 @10:10AM (#23192385)
Toyota is still focusing on fuel cells, which, I think is dead for consumer cars, however I think makes sense in long distance travel for large vehicles (trailers, for example).

I think the death of ICE manufacturers is overblown right now, pending a major increase in battery tech by Tesla, which would just be awesome - but Buying an electric car right now is not a financially smart move for most buyers. First, the biggest market in automotive, crossovers and SUVs, there are not any affordable options for electric vehicles. Even in the sedan segment, with gas so damn cheap, the Model 3 just isn't worth it if you care about saving money.

Re:Tesla's batteries aim to rework the math for electric car... by nickik on Friday May 15, 2020 @06:44PM (#23198394)
Fuel cells don't really win compared to gas. Its hard to see any adoption of them even in those areas. For utility vehicle the price matters very much, and hydrogen is not cheap.

The ICE manufacturers are not gone die just like that for many years, however the question is, when they have all made the transition, what will the market share of Tesla be and who will they take it from.

The problem for old manufactures is that they have a gigantic capital investment in things like engines. A lot of that investment has not been amortized. Switching to EV requires both a massive investment in redesigning all cars to be EVs, huge investment in retooling your manufacturing and a lots of margin if you don't build batteries.

All that goes into your margin for EVs, and thus they are terrible for most automakers. So you are forced to sell a product that doesn't make much profit and requires a huge capital base, when you already have a huge capital base for producing marginally profitable ICE cars that are dropping in resale value quickly.

I think I disagree with the point about finaces. Sure a cheap ICE car is better, but when buying an car comparable with a Tesla in price, I rather have the Tesla. Gas is cheap now, but power is still cheaper usually. Gas could be more expensive again for many reasons. In 5 years ICE car will have basically no resale value while EV should hold their value much better.

All that said, buying a cheap ICE car with an efficient engine is the way to save money. Or use public transportation like me :)

Re:Tesla's batteries aim to rework the math for electric car... by ntsplnkv2 on Saturday May 16, 2020 @01:55AM (#23200820)
Fuel cells win in one extremely important area - they're far cleaner. If we can find ways to make it cheaper (funny, everyone always gives Tesla this benefit of the doubt), it could be viable.

This isn't like Google. There will be some brand loyalty, but tastes change, and 99% of car sales today are not all that dependent on the drivetrain. People buy cars on things like how they look and the features they have. Eventually when battery tech is competitive there will be more options.

Ultimately it's not a huge loss - you still need wheels, brakes, drivetrains, and all of the other work that goes into making a car, a car. Only now you have a much simpler motor, without a need for a gearbox. Really, I'd argue that Tesla's only advantage is the battery. That market, imo, is far more lucrative - making batteries for other carmakers is eventually what will happen. Retooling happens relatively often - when new platforms are developed. It's not like cars are manufactured today like they were 50 years ago.

> I think I disagree with the point about finaces. Sure a cheap ICE car is better, but when buying an car comparable with a Tesla in price, I rather have the Tesla.

I don't see how you can disagree about finances and then argue "but if I'm buying a luxury car..." That's exactly my point: it's a luxury car. I've been hearing gas prices will go up for over a decade now - they haven't, and I'd bet they won't in 5 years. There's too much supply now, and more supply coming (arctic reserves, for example). It will be awhile before prices go back up. And on top of that - it's a luxury car. Why care? No one cares about luxury car resale value - everyone just leases them anyway.

It's just argument after argument about how this is better but the bottom line is they're too expensive, and really not economically better than most ICEs. Without a doubt, no better than any hybrid, in terms of cost.

> In 5 years ICE car will have basically no resale value while EV should hold their value much better.

I'll bet you :)

Re:Tesla's batteries aim to rework the math for electric car... by nickik on Saturday May 16, 2020 @09:41AM (#23203287)
Clean itself doesn't sell, specially in utility vehicles. And the reason Tesla gets the 'benefit of the doubt' is because they are already selling 100ks and have many more orders and they are riding a cost curve of battery improvement that doesn't exist with fuel cells.

Some people want luxury cars, so I don't know what to tell you.

EV are gone expand increasingly fast every year, in 5 years buying a new ICE Porsche will seem idiotic, mark my words.
