That is a very interesting model.

* They can charge at a slower rate, because they can average it out over the day
* They offer frequency balancing to the grid
I recall hearing that Irish voices are the most trusted in Western countries, and now I wonder whether that's something to do with the high degree of authenticity in the voice.
Edit: I tried to find a source for the Irish voice thing, but it turns out that every country lists a different accent as most trusted, in India it was British, in the UK it's Northern Irish, YMMV so it is probably irrelevant which voice is most trusted. The gist that the US voice being so present in voice assistants, devices, AI voice bots, etc still directionally may indicate a lessening in trust in those accents where it's not obviously tied to a speaker on screen being obviously human.
Edit 2: Now I think future demand for video conferencing for support will increase, as people will not trust voice calls at all.
> The phenomenon of AI voices _and_ American voices choosing to be in a "presentation mode" / "telephone voice" is disconcerting
I wonder how much of this is choice, or availability of crisp training data
When electrical cars first appeared on the market here in Europe leasing the battery was usually the only option. Luckily not anymore.
The hotswapping adds an interesting component to it though, that's true.
Buying the car and paying a reasonable monthly subscription to always have an available swappable battery is not bad at all.
When the battery kicks the bucket, the battery-leasing company has to buy a new one, which costs money. The battery-leasing company makes money from battery subscription. Your subscription must cover the cost of the replacement batteries.
For a new car buyer this system likely has a much better total cost of ownership.
Why this might be a much financially better option for customers is if battery tech costs keep reducing rapidly. So instead of paying the cost of 100kw of battery tech in 2023, you will pay something like an average value of the battery tech cost from 2023 to 2027 (and if the industry is growing, like EVs are, it will be a weighted average where the cheaper newer batteries would have higher weight since they would be a larger proportion of the overall stock since more cars will be made in 2027 than 2023).
Basically with the condition that battery costs keep dropping, this could be a fantastic deal for customers since they don’t need to buy the batteries at the most expensive price they will ever be going forward.
Looks like the most vanilla 2008 blog site possible
EVs are weird. Certain usage patterns mean less time waiting than ICE vehicles.
360Wh/kg for batteries is very noteworthy since some of the very best 18650 or 21700 format, higher amperage capable, li ion cylindrical cells used in UAV applications are right around 255Wh/kg.
Still impressive, but not exactly shocking for a sedan with a 150kWh battery to be capable of this range. I think the more impressive thing is cramming 150kWh of battery into a 4 door sedan.
You can have a 75 kWh battery most of the time, swap to a 150 kWh for a road trip, and then swap back to a 75 kWh for your daily driving.
It means you don't own the battery, but it also means you can change to a new battery whenever you want.
Tesla guarantees the battery for 8 years or 192,000km. If the battery degraded to below 80% of spec, they replace it for free.
Meaning that probably 95% or more of their batteries still have a higher capacity at that point. Modern EV batteries are really good.
A car that's 8 years old or has 192,000km will probably have lost about 70% of its resale value.
How has the car held up other than the battery? You say it has wear and tear like a 10 year old car but that can mean drastically different things depending on how people normally maintain their cars and what kinds of environments they drive in (local to me in upstate NY we use a lot of salt on the roads, an average 10 year old car is likely going to be nearing to the end of its life due to rust issues whose repair cost may equal a substantial portion of the value of the car).
NIO are already doing at least part of that by charging the batteries during time of excess energy only
The 1044km claim is from a livestream where the CEO of the company drove the car from Shanghai to Xiamen until there's 3% left in the battery. All this amid a cold wave too.
> The temperature during the test was between -2 °C and 12 °C (28 – 54 °F). The coldest time was at the beginning of the test, as it was early morning in Shanghai. The average cabin temperature was 20 °C (68 °F). The carload was about 190 kg (two adults, lifestream equipment, and other items).
A livestream is hard to fake but what tires were they using? What was the climate control setting? What speed? Did they have a tail wind?
The maximum speed was caped to 90 km/hour (56 miles/hour), and the energy consumption was 13.2 kWh/100 km. The average speed for the trip was 83.9 km/h.
In May 2018, Sean Mitchell and Erik Strait set a hypermiling record for the Tesla Model 3 by driving 606.2 miles on a single charge after 32 hours of driving.https://www.cbsnews.com/news/tesla-autopilot-staged-engineer...
And they clearly can use a rigged car, cherrypick conditions etc. If it even were live.
But I generally don't like to throw legal terms around unless it's been proven in court.
