silence_kit posted:If the governments of the world seriously commit to wind and solar energy generation, something like this could be used to use/store the excess electricity the intermittent sources generate. That's a big "if". Kind of like how if consumers would either stop requiring peak levels of load, or accept less than perfect system reliability, intermittent sources would already be more useful. Everybody puts the blame on utilities or the government, but it is consumer demand and their wasteful peak use of electricity that is the problem.

I don't have time to read and get into the articles, but does the "completely destroys Fuel Cell EVs" article actually take into consideration that the technology is in it's infancy and that just because most hydrogen is extracted using fossil fuel now, it doesn't have to be in the future? Same with "bad infrastructure", which is something that EV's still suffer very much from? Usually people whining on hydrogen compare them like they are at the same point in development. Usually they have the same arguments against hydrogen that exist (albeit at a different level) for EVs.

The arguments are the same because infrastructure is important to both. Heck, buying a diesel car gives some people pause. The differences between FC and EV infra gaps are pretty meaningful IMO. The world is already blanketed with means for producing and distributing electricity, so EVs really face a last-mile problem of adding grid access points. Hydrogen has first mile (production), last mile (delivery), and middle miles (transport) problems. I think it's entirely possible that we'll never see good FC infrastructure, because the demand won't be sufficient to build up the whole industry, while electrical generation and battery tech and so forth have lots of motivation outside of EVs.

Gives me some time to save up some cash at least. The 3 comes with free Supercharging, right? I seem to recall that being confirmed. There's a Tesla Supercharger station just under a mile from my house so that's a tad important.

They've started cracking down on people "abusing" supercharger stations by using them to charge all the time, so they still expect you to charge at home most of the time. Also LOL the Model X is delayed again and the autopilot package I prepaid for is still missing most of its features including stuff other cars have like auto park. I wouldn't count on the Model 3 anytime soon.

Tesla just opened a supercharger in Mountain View, which is 5% Model S by volume, so they'll definitely have to crack down on people using it for regular refilling.

I personally wouldn't bet my savings on it, though some people definitely have given TSLA's stock price, because you'll still have to sell a lot of people who won't go for electric yet because it's too new and different. Early adopters will certainly get this company off of the ground, and have already, but my guess is it will stay in early-adopter phase and Tesla won't be able to stabilize for a long time. I bet you'll still have to hunt for one on the road. I understand some people in California will run across several Teslas on the road in a day, but think about how many you see from the other makes.

Depends on the area. I see Teslas weekly in my area, no hyperbole. One day I saw four in an eight block radius, and I'm nowhere near Seattle or a metro area. That's ignoring the fact that I live a mile from the Supercharger - this is where I work, 30 minutes away. Once a more affordable 3 series is available, I'm pretty certain a lot of people that are on the fence about EV cars will pull the trigger. I'm interested in what happens to the market. Overnight it almost instantly invalidates most every other manufacturer. Why buy a Leaf at that point... direct to consumer blocking legislation aside?

roomforthetuna posted:Some sections of Google have surplus EV parking at the moment (to the point that there's no parking nearby for regular cars but several charging spots open). I'm sure that ratio must be gradually decreasing though. It's cool that so far they're staying ahead of the curve. That's pretty impressive. FB has the valet rotate cars through the charging stations, which works OK, but we're going to need more capacity.

Miami has AWFUL EV infrastructure, and Model Ses are all over the place. The whole point of Tesla's success is that the car has enough range that you don't have to carefully shepherd it from charge point to charge point for 90% of normal driving. EV infrastructure is great, but a 200mi+ range makes it mostly irrelevant for most use cases.

Teslas are everywhere in Walnut Creek and elsewhere in Contra Costa. Hell, it's rare that a day goes by without seeing one.

MrYenko posted:EV infrastructure is great, but a 200mi+ range makes it mostly irrelevant for most use cases. I would agree with that. I can really only think of a handful of times a year that I would need >200 miles worth of range in one day. My parents only live 25 miles away, my sister only lives 60. I could see maybe if I visited my sister and then decided to go somewhere else that day without charging I could come close. Otherwise, it's just stuff like driving down to DC from Pittsburgh to visit fiends. Even that is somewhat doable if some planning was done and I wasn't trying to make good time as there's a Supercharging station in Somerset and in Hagerstown. The big thing that would give me range anxiety in those instances are road closures. I HAVE been detoured off the turnpike before due to a wreck and if I had to detour around the Supercharger in Somerset, I would basically have to abort the trip.

bull3964 posted:I would agree with that. My biggest question about range is how much affect rush-hour stop and go traffic in 110+ degree temperatures would affect it. My commute is 52 miles one way in those conditions, and sometimes I actually like to not go directly home after work, and I always go out for lunch. Would be awesome to get an EV, but I'd really want to know what that sort of driving does to the range before I could risk the investment in one.

Typical car A/C is about a 4 horsepower draw, and in Arizona in summer that's a continuous load, so while it's small, it's still enough of a load that is seems it would be a factor when you are talking about 90 minutes of travel (each way).

Seems like an EV might have a bit of an advantage over a typical auto A/C, in that the compressor can spin at full speed (or possibly be varied) independent of the vehicle / engine speed. Either way, 4hp would be about 3kW, or about 5% of a base Model S 60 kWh battery pack for every hour of usage. So three hours of commuting with the A/C running the entire time would suck up about 15% of the range on top of the actual driving itself. I'd still bet that even in AZ the compressor wouldn't run 100% of the time on a drive like that, though. Of course, any gains there would be countered by any derating / other losses on the battery itself from being so loving hot. That's the biggest problem the Leaf has.

Assuming your figure is correct we can figure out how much A/C impacts range. 4 HP = 3 kW so to run that for 1 hour is 3 kWh (makes sense, doesn't it? ). The Model S85 battery pack is 85 kWh which this document says has an available capacity of 67.4 kWh for normal driving. With that amount of charge you could run the A/C for 22.5 hours continously. Another way to look at it is how much range you use: the EPA says the S85 uses 38 kWh/100 mi or 380 Wh/mi. That means each hour of A/C use uses 7.9 miles of range.

Thanks for the info. The S is out of my price range, but if we get more moderately priced cars with 200+ mile range, they will be on my radar and this helps me figure out the real world range issues I'd need to deal with.
