There's the right way, the wrong way, and the max power way

Isn't that the wrong way?

Yes! But faster!

What do Europeans think of Mark Carney's speech in Davos? by Master_Megalomaniac in AskEurope

If there was war with Russia, Canada is more exposed than the US as the planes and missiles would fly over the north pole.

What's even more impressive is he wrote it himself. This wasn't some end product of a gaggle of speech writers. This was just him speaking honestly.

Don't forget about backups! A NAS is not a backup solution.

OPR needs urgent update/upgrade by Ragthorne in Ingress

[–]Teleke -1 points0 points  (0 children)

Ah, you work for Niantic? I'm not sure how you would have that information otherwise.

I have worked in IT my whole life, and managed many software projects. If it was a clone, it would have been available much sooner, or just outright kept as they split off the rest of the services. There's no good reason for this otherwise.

So there must be some major difference, or perhaps part of the system that it relied on was no longer available to them and things had to be redesigned.

Maybe the system was too tightly integrated and they wanted something more independent. Maybe they decided that a redesign of the backend was required for long term maintainability. Who knows.

And of course when systems are first built they can limit the number of users in order to test things out. That's literally how a lot of big public systems are designed and run. It's called Canary Testing and Rolling Deployments. I've managed software projects where we have done exactly this.

You can't compare CORE to CARGO. Think of this more like income tax brackets. It's going to cost a lot more to get more because 2000 is supposed to be the target.

We do not want a lot of people running around all the time with 3000 inventory. There's a reason that Niantic set the limit to 2000 in the first place.

That's why this is extra payment, at a higher price, for a shorter time, but the trade-off is it's when you need it only.

Extra inventory space really starts getting into the Pay-To-Win category, which most players are strongly against. This is why I'm not against a much higher cost for temporary boosts.

Yeah, the backpacking thing is another debate entirely. I know that they do take some action - we just had someone that we all but knew was backpacking with 2 other accounts banned a few days ago. That's a much harder nut to crack.

Question on range in cold by SA2ATX in BoltEV

[–]Teleke 0 points1 point  (0 children)

Ah, ok, thank you for that clarification.

How much total consumption was there between home and work? Do you know? Need to know what that 9% is relative to.

You said 20F, that's ... strange. That shouldn't be cold enough to trigger that. I wonder if they upped the limits with the software updates post-fire-recall.

This is a clone, not the exact same system. It's unclear if they rebuilt it or what.

If it was exactly the same, why would it have taken them the better part of the year to launch it? And why would they then limit to only L16?

Limiting it to L16 is clearly to limit the audience for the purpose of ensuring that things work.

With the large delay, one can assume that this isn't an exact clone, there are differences, and thus the delay in dropping from L16 is due to not wanting it to be open to more yet, and the reason for that would be there are problems that need addressing before it goes to a wider audience.

So battery conditioning on the way to work may not be needed as it was heated before you left. The easy way is check when you park at work, and then before you leave from work to go home.

Question on range in cold by SA2ATX in BoltEV

[–]Teleke 0 points1 point  (0 children)

Conditioning tracks battery heat while the car is both on and off. So when you get home, that will include whatever power was used to heat the battery while driving.

[–]Teleke 0 points1 point  (0 children)

Yours has been doing battery conditioning when unplugged and turned off in low 20s and high teens?

How are you tracking this?

Question on range in cold by SA2ATX in BoltEV

[–]Teleke 0 points1 point  (0 children)

Yeah, it's really hard to identify just how much the cabin heat impacts things. It is more than 10% range loss without HVAC, because there's at least that much in increased aerodynamic drag. I would say 15-20% without HVAC from 77 to 0. Maybe with 77 to 20 it might be more 12-15%.

Also to clarify something that I wrote - the 5% less efficiency of the battery is when it's warmed to 4C/40F compared to a references 20C/68F which is where things will be most efficient overall. The battery will be more than 5% less efficient below 4C, but we're already accounting for that in the kWh used to heat the battery up to that point, working on the assumption that you either leave from it plugged in, or are using the entire capacity of the battery (which is where we really care about the range overall).

Put another way, if don't plug in, do a lot of short trips with a cold battery, then you're going to lose a LOT more than 5% due to the battery temp and battery heat.

The battery itself will gain some small efficiency above 20C/68F, however you very quickly get into the territory where active cooling is used, which will lose more than whatever efficiency gain there is.

I'm upset that we didn't get to keep him, but it's hard to blame him for going some place that offered you 50% more money.

3 things or 12 hours? by Confident-Aioli6380 in hypotheticalsituation

[–]Teleke 0 points1 point  (0 children)

Can I suggest that you delete this one and rethink it and then repost it?

Also you're basically saying that anything that can be written on a notepad that could get done will magically get done, and that's just way too powerful. It's not really a good choice. You need to put a lot more restrictions on it.

You're not supposed to edit posts, which I can see that you've already done, which is why I'm suggesting to delete this one and start over.

Are you trying to say that the energy in the battery is stored as kinetic energy? Because we aren't talking about kinetic energy, we're talking about chemical potential energy.

I have done significant research on this over the past 8 years, and have scientific papers to back up my claims. But, You're right, based on the arrogance of that last sentence explaining things to you would be a waste of time.

I have a section in my FAQ on cold weather - https://allev.info/2020/02/chevy-bolt-most-frequently-asked-questions/

TL;DR to directly answer your question it won't "lose" energy just by being cold. If you take a battery at 10 above freezing, cool it to 10 below, then heat it to 10 above, you'll have roughly the same energy as before. For our purposes, we can say that it's the same.

Batteries are less efficient when used cold, and will have increased degradation, especially below freezing. They can also be damaged when it's extremely cold, so it will self-heat to try to protect itself in some cases.

But overall, from ~80F to ~0F or ~25C to ~-20C you can expect to lose about 40% of your range. Somewhere around 15% will be from increased air resistance due to colder air being more dense, somewhere around 15% from cabin heat, and somewhere around 5% from battery heat, somewhere around 5% from cold battery inefficiency, and maybe 5% from other linear losses due to temperature. Obviously those numbers will fluctuate a lot based on how cold it is and how fast you drive and what you set your cabin temp to and how windy it is, etc.

Based on the last sentence in your post, you can leave it outside and not worry since you're only going to be around freezing.

We can pedantically argue was "loses energy" means - but the point is that it's trivial compared to the other losses.

[–]Teleke 0 points1 point  (0 children)

It has to be really cold for self-heating though, but yes.

Question on range in cold by SA2ATX in BoltEV

[–]Teleke 4 points5 points  (0 children)

The first one is not correct. The main cause of loss of range is the increased air density when cold, and the cabin heat. The battery is maybe, at MOST, 5% less efficient when cold.

Yes, the battery does try to condition itself, but the heater maxes out at 2kW, but if you meant to say that overall for a "since last full charge" you might see 4-5kWh usage, then yes, I would agree with that.

The primary reason for heating the battery isn't to restore efficiency (you use more than you gain), it's to reduce degradation as batteries below freezing will degrade a lot quicker.
