I don't know about grid capacity, but yes, night time charging is what most people can use to cover most of their transport needs, not long rows of superchargers. That means street parking and parking garages need charging stations. BYO cable, plug into Type 2 outlet or similar AC, get 2-3 kW. The power of one single supercharger can charge a streetful of cars. Going for a 200 mile trip but can only get 100 miles overnight? Drive 80 miles to the supercharger, have a coffee and a piss, keep going. Better cable security would be nice, have been some cases of theft here. The cables are expensive and the locks aren't that solid.

Get a high enough density of cables and someone will decide it's worth their while to get some insulated cable cutters. I remember reading about a project to make electrically conductive cables made out of carbon, which were basically worthless except as conductors and couldn't be melted down and recast like copper cables can be. It'd be a real boon to places like Africa where cable theft is rampant, but I wouldn't mind having such things in the US as well.

I guess part of the reason is cost, it's a big % of a small 3.6 kW station, there's also different plugs on the current cars, Type 1 and Type 2 (other end of cable has Type 2 on both).

Saukkis posted:Would the 350kW charging really matter? The deciding factor should be how much energy the car uses during the average commute? More powerful charging stations just means the car needs to spend less time on the station and there would be less cars charging at the same time. And larger batteries means the car needs to visit the station less often. Gas pedal is still what determines how much energy is needed in the end. An interesting thing that factors into this is calculating the power usage of a traditional street lamp and the new LED street lamps that are replacing them. My city of 100,000 is replacing 10,000 HPS street lights with LEDs, cutting power usage from around 400w/light to 200w/light taking 2,000kw off the grid. over 8 hours, that's 16,000kwh, or enough to give 1400 teslas 50km of range every night, and that's just half of the street lights. 10 years ago around 8-9 pm, every one of the ~40,000 houses would probably average 5 60 watt lightbulbs on. now they average 5 13 watt CFLs, soon it will be 5 4w LEDs. That frees up 280 watts per household, again, enough to give around 1100 cars 50km of range. Flourescent tube LEDs in every bank, office, store, or school use 17 watts, vs the flourescent's 32 watts. Just LED light bulb efficiency frees up enough power to give 50km to probably 5,000 - 10,000 cars a day in a city with 40,000 households.

EV's increased electrical load on the system will be solved by micro-grids. The Gigafactory just added a lab for them.

The future of transportation (I really do want to murder whoever made "mobility" a thing) is going to be multimodal, and one size isn't going to fit all. Everyone has their own special edge case and the solutions won't all be the same. If you spend 51 weeks a year just commuting to work and driving the kids to soccer practice, you don't need to buy a 4x4 Land Rover/G63/etc just because you go camping off road in the mountains one week per year. That's just pissing away money.

Collateral Damage posted:This is a few pages back but I think you're on point. Buy a car that covers 95% of your needs and rent another car for the rest. People are obsessed with "EVs aren't market ready until they cover my every imaginable corner case!" If I had been able to get a 200mi range EV in 2013 when I bought my Volt, and NOTHING ELSE had changed, I would have needed a different car four times. If it was a Tesla, or otherwise able to access the supercharger network, that number would be zero. (Other DC fast-charge systems are rare as hens teeth, here.)

They didn't want to produce both motors, since that would "double the chances of something going wrong" with early cars, since the motors are different designs. And I think the options to choose for the first builds are color and wheels, but that doesn't mean the first ones will be poverty spec. They've streamlined the options available for the S to be "Premium Upgrades" and the rear facing seats. If they treat the 3 similarly, the first cars off the line may have the larger pack, and the premium package, and that's it for options until they add dual motors. Edit: Here's an imgur album with some photos pre-show. http://imgur.com/a/socyu There's a pic with 40 Model 3's, so looks like they've beat their estimate some. borkencode fucked around with this message at 04:19 on Jul 29, 2017 |

https://www.wired.com/story/i-drove-a-tesla-model-3Wired posted:Initially, Tesla is building just two configurations of the car, to keep things as simple on the production line. The base will be the $35,000 version, with a range of 220 miles and acceleration from 0-60 mph in 5.6 seconds. The “long range” version will go a claimed 310 miles between charges, and do the 0-60 sprint in 5.1 seconds—but it’ll set you back $44,000. Both models come with just one electric motor driving the back wheels. The twin motor, the all-wheel-drive option, will follow in a few months. (In a break from tradition, Tesla won’t talk kilowatt-hour battery sizes, saying that customers understand range in miles better.) So I was pretty sure that the base model wouldn't hit 300 miles in range--and I was right about that--but I'm kinda surprised they couldn't get it to beat the Bolt. I guess I'm kind of neutral on the whole thing. I can't shake the feeling that the interior is a turd and the exterior is a Mazda 3 (which I like, but still). Maybe it just takes some getting used to the dashpad. Still, the more competition the merrier and I look forward to seeing how the other manufacturers respond.

56.5k for long range with enhanced autopilot and premium interior. The 3 still isn't *cheap*, but its better than an S. I'm still on the fence on taking my reservation or not. I'd like a long range dual motor in early 2019. Maybe I can defer that long... I guarantee I'm not buying one without driving it first.

The vents are computer controlled and you can shoot them at whatever direction you want. The two control nub wheels remain. The test driver somewhat awkwardly changed the steering wheel height using them on the touchscreen while driving.
