yea, 100kwh is too few. 170kwh would be ideal (for a model 3). The models S and X should have had a 250kwh pack, to support that needlessly fast acceleration.
I think 100kWh is ideal for a Model 3. I drove my LR RWD across the US (MS to CA to WA) and didn’t really have an issue. It was only bad when it got really cold outside, so having an extra 30% would cover that. It would have about 400 miles of range on a full charge, and 20 mins at a super charger would get you from 10% to 80%, so 300 miles, or another 4 hours of driving.
600Km in a single charge ? 450 km mileage in 20 minutes ? i am surprised. although i would feel more safe if a 20min stop adds another 150km (yea, 30% increase in battery size would be cool) (but how about running ac, towing stuff ? that could really decrease the efficiency) nonetheless, home charging is costly if u plan on adding 70kwh ever night to ur utility bill. so as a commuter, i should predict a 20 min stop to supercharge cheaply before getting home. then tomorrow, another stop mid day.. Superchargers will be congested if this isn't adressed, u hav a factor of 20x to tackle: people would fuel up with gasoline in a 1 minute or so instead, if everyone where to have EVs
At home, most people are only charging about 10-20% every night. For 100kWh, let’s say 20kWh, which is 60 miles. Most people at home will be using a 240v 50A outlet, which outputs 12kW. You’d be done charging in about 2 hours at 95% efficiency for 21kWh from the outlet (heat loss and whatnot does take a significant portion of charging). At my place with $0.13/kWh, that would just be a measly $2.75 at 95% efficiency. Wayyyy cheaper than gas. That’s around the same as a car with 85mpg at $4/gal gas. Most cars are around 30mpg on a good day.
a Mk6 diesel would do 60mpg..but again, prices would also influence this. Yea well, as long as electricity stays cheap, and cost of the supercharger stays also low, then that would be a viable choice (i wonder how much 1kwh costs at a supercharger?). Also, when a company judges a product is too good, it would pull a premium from its ass just to drain money from its customers, especially, in the case of OTA connected cars like Teslas, anything could happen. Lithium mining becoming too expensive: u only get to use 75kwh only of ur battery (idk, similar non sense.. remains to be seen, depends on a company goodwill..like when they retracted free supercharging from Legacy S and X owners, straight rug pull) . Also again, cheap electricity would imply congested superchargers in the future :/
diesel is literally destroying the planet with both particulate and CO2. I'd factor that into the costs. I'd rather pay 200% more for electricity if it means we can sleep at night knowing I'm not poisoning the environment to drive around everyday. You can literally use solar panels to charge your car and batteries can be 99% efficiently recycled. yes tyre dust is still a huge problem we need to fix. but petrol and diesel need to die asap and not be considered as viable options.
a car releases alot of fine particles, i agree, even brake pads release particles. fossil is not only polluting but it is also finite as a ressource, and also is uranium. air travel is addicted to fossil and that needs to stop: electric powered trains could make for a good alternative, but u would need long stretches of land to produce enough energy to satisfy these needs through solar, while waiting for fusion tech to be unlocked
