Endymion FRS MK1 posted:Question on how to calculate energy cost. My bill doesn't say what the price per kw is. It only says if I shop around I'd need to find someone charging less than 6c/kw to be competitive. If I divide my total monthly kw by what I owe, it comes to ~12c. Including supply/delivery/transmission or whatever. So what price should I be comparing? It can be confusing, often utilities do not provide an itemized bill. You can probably look on they website and find the residential favorites charge and kwh rate.

Qwijib0 posted:For homeowners at least, even a modest solar array will generate enough kWh to cover most daily drives. In latitudes as north as Minnesota, a 4kW system will on average generate ~13kWh per day. In Arizona, I get ~23 kWh off my 3.8kW system. Your PV is probably not producing while your car is at home and plugged in though. Except maybe on the weekend...

I think he is banking on the way *most* electric utilities deal with net metering, where your PV array generates credits for whatever you feed back, which erases kwh used later to charge your EV (or whatever). This arrangement will stay this way until residential solar becomes economically unworthy of the good PR, and they will start treating it like the fickle off peak generation that it is, with lower payback to match.

I can't wait to tear the degraded 62kwh battery out of my leaf in ten years and use it as home storage. Old Post... You should be able to fasten anything to a cybertruck, right? Surface mount steps, handles, roof rack, spikes. As far as the warthog comparison goes, it should make a pretty decent technical, right?

Nitrousoxide posted:You should care when your $15k+ battery is only capable of storing as much energy as 2.5 gallons of gas. Sure but I can look at the Watts per mile realtime. Driving super conservatively gets me like 20% more range than driving however I want. It charges every night. It's not really a big deal. Maybe it is for you but I've just found it's not worth worrying about. I get that more efficiency is good, but there is no point in buying the performance version and then driving it like a prius. The only time it is a big deal is long trips, and I've found the largest difference with that is how fast you go on the freeway. Going 75 vs 70 is a much larger difference than anything I do in town. I think I am coming at this from a different angle than you, I view it as a sports sedan with incredible mileage, not a hyper efficient thing.

And the hope that by the time net metering disappears, a reasonable sized battery storage solution will be more affordable-- closer to $200/kWh than the ~600 it is now. Yes, it's a lot of optimism.

There will be an Electric Mini. If it handles anything like my old Cooper S then it'll be superior to the Bolt as far as handling goes. The Bolt feels bigger probably because it is.

Over the past couple of months I've test driven a Leaf, an i3 and an Ioniq, and took a passenger ride in a Zoe. Thought I'd almost certainly end up buying a Leaf, but actually found the Ioniq to be the nicest of the three (this is the recently updated version). Liked the interior, liked the ride, thought the 'modest' looks suited better than something obviously stand-out like the i3. So, order placed for a new Ioniq. Looks like it's going to be a few month's wait in the UK, but hopefully I'll have something for Spring next year. Never had a new car before; pretty cool that it gets to be my first electric car at the same time. This is long past due - I basically only make one trip a year where I'd need to charge on the way and most of the rest of my time is stuck in traffic. Can't really kid myself I need anything more than a runaround any more.

We have a 2018 plug in hybrid Ioniq and it turned us on to getting the 2019 Kona EV as well. No real complaints for either, though now we're weirdly a Hyundai family from owning a Chevy and a Saturn.

Depends on where you live. California gets very little power from coal (under 5% of total generation). Afaik most coal plants are being converted to natural gas plants all around the US too.

In 2015 it was actually worse for environment to run an EV in places like Ohio, but even though there's still a lot of coal, that's no longer the case (some coal went to natural gas, some went to renewables, some got better scrubbers) *edit* paper here

No real complaints for either, though now we're weirdly a Hyundai family from owning a Chevy and a Saturn. That's good to hear. I'm not massively questioning the switch, but always good to get some confirmation that this is a good choice. The reason I thought I'd end up with the Leaf apart from it sort of being the default option here is that I've had two Nissan's previously with no problems. So I'd consider myself to have some loyalty there but having driven the cars, I just liked the Ioniq a lot more.

pun pundit posted:Also, as electric vehicle market share inreases, electricity required to refine gasoline decreases. If the 8 kWh figure for one gallon (drilling, transporting, and refining) holds, electricity use will go down as people swap to electric cars. It'll move from centralised to distributed use, though, so the grid could probably do with some changes. Is there a good source on this? I'd like to understand the efficiency of refining.

I did some research, but it's really hard to collate the data. The 8kWh/gallon value seems to be an "accepted industry average" but the work to put it together is beyond a hobbyist statistician.

Which I just find odd because everyone with an opinion can tell you to the milligram and milliwatt•hour exactly how much carbon and energy it takes to recharge and build every nut bolt and anode in an EV.

It is weird. Tesla use Samsung cells for their home batteries with a slightly different chemistry. The electronics are a bigger proportion of the product given the relative size of the batteries (13kwh v 60-90). But it must mainly be volume. The difference is enormous.

SerCypher posted:Do powerwalls have active cooling and such? Yes They have liquid cooling and "active conditioning" so they're thermally managed and hypothetically look at weather conditions and stuff. If it's tied to solar it warms up before sunrise so the batteries can accept a full charge, etc.

mobby_6kl posted:That's what the regen braking is for. Do it, don't be a pussy. It's an issue where the regen doesn't work either, complete power assist failure. The parts alone to fix it are over $2k. One thing about EVs that I'm kind of apprehensive about is because they are still such a new thing that it's an excuse for shops to rake people over the coals for repairs. Having an EV out of warranty could get pretty loving expensive if batteries and anything in the drivetrain needs to be repaired or replaced.
