Michael Scott posted:3,786 lbs for the 2015 Volt, excluding the driver's weight The Volt is a fat pig. It's a pleasant enough pig, though. With the AC cranked to max, at idle in gear, the display shows the car drawing 2-3kw. With the AC on my normal setting (eco/auto and 72-74°F, and 88-90° outside,) it shows <1-1kw. A steady state 55mph cruise with the AC set to the same is generally 8-11kw, 70mph is 18-20. Pushing that thing through the air at speed is a LOT harder than turning the AC compressor.

In L.A. I see Teslas ALL the time. Multiple Models S in a day. I just wonder how so many people can afford them. And I'm also jealous as gently caress. The Model 3 can't get here fast enough. Fortunately for those of us with reasonably short commutes (mine's 26 miles/~1 hour roundtrip) there are more affordable options. I'm looking at the Kia Soul EV, VW e-Golf, and Leaf. Honestly the hardest part about evaluating if an EV is the right choice for me isn't choosing the car itself, it's trying to figure out the incentive structure for my area to determine the true cost after rebates and other incentives. For example, the state of California has a $2500 rebate for buying or leasing an EV ($1500 for a plug-in hybrid), but then the South Coast Air Quality Management District also appears to offer a "rebate" of sorts if you trade in your old car to be retired. The amount I can get seems to be about what I'd able to sell my current car (98 MBZ C280) for third-party, and there's some value in not having to deal with selling the drat thing as well. But it's hard to get detailed information and their website (https://www.replaceyourride.com) sucks monkey nuts, so I'm stuck sifting through mountains of information to try to wrap my head around the whole thing and actually make an informed decision. What the EV market really needs is a thorough and easy-to-navigate resource to help you make a true and accurate comparison among EVs and other options, taking into account all the incentives offered in your particular area.

Is that 26 miles one way, 1 hour round trip? Or 13 miles one way, 1 hour round trip? It's not very hard to do the average speed math either way, if it was me I would be looking for my commut-O-matic right here: http://www.zeromotorcycles.com/ As for the incentives, I wonder if the used market might be a better bet by now. EVs seem to be depreciating a bit quickly, might be worth checking out the second hand market. Keeping the Merc and getting a year-old VW E-Up! might end up being a good equation.

Chris Walken posted:It's 26 miles/~1 hour roundtrip. So 13 miles/~30 minutes each way. About half freeway, half streets but varies slightly depending on which route I take. I'm actually looking into a 24 month lease of an EV. Those are words I NEVER thought I'd say, but the Merc is starting to need a lot of expensive repairs and gets 20mpg in the city, and at the new job it bakes in the sun for 8 hours and is 1 million degrees when I get into it to drive home (it's black on black). Ah, right, so the lease is sort of a given. I don't know about the incentives, but I can bring another tempting fact to the table regarding those hot temps. Many EVs (Tesla, Leaf, VW, perhaps more) have apps which lets you turn on A/C remotely.

Numbers should be accurate, as they had a meter reading off me a little over a week ago.

I think a lot of people have the same experience given how much free charging is available. I expect that to change towards pay to charge in the future, but not this year or next. But about the consumption, 65 kWh is 3% of 2166 kWh. Is that the annual number you got? It seems low, perhaps the difference is in utilities. I live in a small loft apartment, I don't need to heat that much in winter and I don't use A/C in summer at all - however I do cook and heat water electric, perhaps you use gas. My annual consumption is 6000-something kWh.

Right, that does explain it. I haven't tallied up my power bills over the year but I do think we might be paying around the same, electricity in Norway is cheap compared to nearby countries. The difference is quickly made up in beer prices.

InitialDave posted:Gas combi boiler and gas hob for cooking, no AC (not really a thing in the UK). Total usage 2500kWh. Heh, I used 1898 kWh in just the month of August in 2013 (the last August I did not have solar to offset this). That's my high month due to A/C in Phoenix, AZ. I have no gas available here, so the house is all electric. I'm currently carrying a 1425kWh on-peak credit into the June billing cycle thanks to the wonders of solar power, but unfortunately if I got an EV it would be charging mostly off-peak, so the solar wouldn't be able to charge it for free unless I got one of Elon Musk's new battery pack things.

I've only been in my current place for a little over a year, but last May (pre-Leaf) I used 1,293 kWh and this May I used 1,505 kWh. I use home charging almost exclusively and only stop at public chargers if I'm in a pinch and think I'm going to run out of battery. It's not a perfect comparison for a number of reasons (we'd just moved in so I may not have been using a normal amount of power, temperature differences between this year and last, etc) but my power usage hasn't gone up all that much. It works out, roughly, to an extra dollar per day. I can live with that.

angryrobots posted: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. I'm saying that if they are really so committed to wind and solar, they could overbuild those energy sources and store the excess electricity as electrochemically generated fuel. If solar energy continues to drop in cost, this may not even be that uneconomical. The fuel could be burnt to supply electricity when the intermittent sources could not provide for it or it could be used for heating or industrial purposes. I think that is what could be attractive about these electrochemically generated fuels, not the idea that they would totally replace extracted fuel from the earth.

At a recent energy producers and distributors conference, the head engineer at Tesla said his expectation was that batteries would be at $100 per kWh or better by 2020. What price do batteries need to be for an EV to be cheaper than an equivalent ICE car? Not counting savings in fuel, etc. My memory from statements by Stephen Chu is that it is about that level or even a bit higher.

Used a supercharger for the first time today (I drove about 80mi round trip at, uh, not the rated-Wh/mi speeds, and I can't charge at home). A very civilized experience: phone alerted me that it was almost done charging, I finished my coffee, walked over, drove away. Charged at 230mi/hr. In general, if Tesla can bring the same sense of polish to the Model 3, I think they're going to demolish that segment of the market.

The Leaf's battery would therefore cost about $2500 and the bigger pack Teslas would be $8500 at this price. I don't know offhand the current price other than that Nissan was offering battery replacements for like $5000 with like no markup so it'd be a very significant drop in price.

IF everything goes to plan I won't be buying a car until earliest ~2020, which is pretty exciting if the predictions that batteries will be at @ $100 / kWh or better by then. If I lived in the countryside with my own garage, the charging would be a piece of cake as you can get up to 32A charging installed. Hopefully by then there are way more chargers in my city. Pretty hard to charge if I have to rely on neighbourhood parking though where you don't have a fixed parking place though. Still, an EV is definately in my sights now.

Same here, will be keeping the Prius and Forester (yes, I am a stereotype, and I don't even live in the PNW (yet)) while we live in greater Toronto. Once we move out west in a couple of years and get settled in, so probably about 4 years, a used Leaf or Model 3 or some kind of EV, maybe even new, is the way to go. By then I expect there will be a much more mature marketplace. I'd love to go full EV now, but budgets and renting mean I can't really commit to it (although I could charge at work, I wouldn't want to have to rely on it exclusively).

Las Vegas recently got its first functional CHAdeMO fast charger. It's also the only charger in Vegas that costs money (for now). I got a chance to use it on my Leaf the other day. Holy balls. It's been over 110F all week so I'm running the air at full blast all the time and my mileage is going to poo poo. Being able to recharge a significant amount in 20 minutes is just wonderful.

Advent Horizon posted:What does that do to the battery temperature? Battery temp was already pretty high on account of it being a hundred and eighteen loving degrees outside, but the DC charge raised it a bit. Not into the red, but the next notch down from there. I honestly wasn't watching the temp gauge because I was too busy watching the battery charge percentage climb.

Again though, as statistics shows, home ownership is down among young people, the average car age is up, and for us apartment owners, Tessa's can't be charged overnight. Another issue wrt supercharger is that Tesla said they are for long term travel only, so a pure EV is useless until the daily chargers are at least as common as say pep boys, which I believe is the largest third party mechanics at the moment in the U.S. Hydrogen is even worse for this because at least electricity is generally everywhere civilization is. I have a partial EV, and as I can trickle charge at work, it's awesome to spend 0 USD for gas driving every non weekend, but yeah, EVs are still pie in the sky tech for these fundamental issues.

In California at least the law is that a tenant must be permitted to install a charger, at their own expense and with a couple of conditions. That should help get infrastructure in more places, at least a bit. I can't currently charge at home, but I can at work and if I take a big day trip I swing by the SC on the way back.

To be fair, the kinds of young people who are lowering home ownership rates aren't exactly going to be buying Teslas either. Or any new car. They're probably the same young people who are lowering car sales, i.e. poor. OXBALLS DOT COM fucked around with this message at 01:51 on Jun 24, 2015 |

It misses the point because the power grid for the whole country isn't just a single reserve of capacity, actual utilization and infrastructure is way more complicated. None of that is addressed at all. Infrastructure is a massive set of problems eith widespread EV adoption and the approach here is basically just to declare that it's Not even though it actually is. Like not even outline likely future advancements or adaptations but straight look at two Numbers and declre the problem imaginary. It's really weAK as anything but another breathless puff piece, which there's already plenty of.

Like, EVs are good and all that but anyone claiming anything close to widespread adoption within the next 5 years is full of it. Even the much hoped-for $200/kWh by 2020 for batteries is, frankly, pretty borderline and likely way too optimistic but then that's the name of the game - build hype, make super optimistic claims, get money.
