Electric car thread

Just saw a polestar. Reminded me of:

Attachment 465413

Kinda agree on the polestar 2.
We’re thinking of this:

I have a question but first some background:

A couple weeks ago some friends from the west side stopped by for a visit and they were driving a Tesla. I noticed that the car was running when parked and asked them about it. Those of you who know EVs know the answer, I did not. The cars have to continually cool which leads me to my question:

Are there issues with the batteries when the outside temp is 110+ for a month like it has been in LV?

Tesla years ago began exaggerating its vehicles’ potential driving distance – by rigging their range-estimating software. The company decided about a decade ago, for marketing purposes, to write algorithms for its range meter that would show drivers “rosy” projections for the distance it could travel on a full battery, according to a person familiar with an early design of the software for its in-dash readouts.

Then, when the battery fell below 50% of its maximum charge, the algorithm would show drivers more realistic projections for their remaining driving range, this person said. To prevent drivers from getting stranded as their predicted range started declining more quickly, Teslas were designed with a “safety buffer,” allowing about 15 miles (24 km) of additional range even after the dash readout showed an empty battery, the source said.

The directive to present the optimistic range estimates came from Tesla Chief Executive Elon Musk, this person said.

Most newer EVs have battery cooling systems to prevent the batteries from overheating. Usually they won't run continuously when parked in hot weather but will cycle on and off to maintain correct battery temperatures. Same thing happens in really cold weather to keep the batteries from getting too cold.

Not really an issue, just decreased range in extreme temperatures as some battery power is used for battery conditioning rather than propulsion.

Correct, it did not run continuously but kept coming on as the temps were in the upper 90s. That said.... it seems worrisome. If I had an EV I feel like I'd sleep better having it parked in a detached garage.

I will freely admit that I'm not sold on the current version of EVs being the answer to our problems because it seems like they come with their own set of issues from the mining of the materials for the batteries to the weight of the cars to the batteries catching fire not easily being extingushed but maybe that's just me not understanding.

The loss of gas tax revenue will have some consequences and produce some ugly battles as well

The sole point of the current crop of EV's is to reduce the carbon footprint of the transportation sector.

Thats it.

They don't solve every environmental problem.
They aren't even a perfect effort to reduce carbon output since we still are getting mid sized SUV's, F150's and Hummers converting as well, they are sometimes charged by fossil fuel sources, materials are produced using fossil fuels, etc.
They don't solve justice issues.

They are just a recognition that we don't have a lot of time to do something about climate.

They are a bridge to something better like hydrogen, solid state batteries, etc.

the other fucking point is for a majority of cases of how people actually use cars they are nicer. Most drives are short and sweet. E vehicles are currently great for that. Lots of the ecar problems are people wanting them to exactly replace the capabilities of their current gas vehicle of which most consumers rarely use.

for those of us living rurally with no charging stations it's not attractive (at the moment).

Wouldn't mass transit and bicycle friendly be a better solution for the environment and our health? I know... I know..... save your fingers, not looking for an answer. I was really just curious about my original question re: the batteries needing cooling and how that works when temps are in the triple digits for extended periods of time.

Meh….

The is operation/function what is attractive to me about EVs. Leaving the house with a full charge. Cheaper operating costs. No oil changes. Etc… it’s a better design for how 95% of us use vehicles 95% of the time….

If the goal is to reduce carbon footprint, there are a thousand other ways that could be more affective.

The environmental piece is just a side effect of owning an EV.

IMO electrifying the transportation system is core to the strategy to reduce local, national, international carbon output. The comfort, fueling, operating costs, etc are secondary benefits that are appealing to the people governments are trying to induce to adopt the technology. It's in every plan you read -> electrify the transport sector.

As for "there are better ways", every plan also goes after those other ways with imperfect solutions as well.

It's why governments are pouring billions into getting people to adopt EV's.

I live where it’s fucking freezing half the year, and some EVs won’t even fucking charge at extreme times. So much angst about cars is about desires not needs

Hybrids are currently a much better solution for many of the reasons you’ve mentioned but they aren’t acceptable

I park my Tesla outside at work in southwest Colorado, temps in the high 90s. I don't know how frequently the cooling system kicks on, but it has never been enough to even use 1% of my battery per day.

I believe the car maintains the battery temperature between 60-80f.

I didn't buy my e car to reduce my carbon footprint but it's a good perk. I bought it because the lifetime cost of driving is way less than a gaspot. One of the other perks of electric is the way it drives, smooth, quiet and quick AF. I've had it for a year and never had any issues waiting around for a charge, on my last 700km day I needed 20 minutes on the e tit which was spent eating lunch. I drove 34000km in the first year calculated cost savings over gas and oil changes was about $4500.

Having to kick out a window to escape a car is insane.
Why do they allow non mechanical exits?

Yes, but it's much easier to solve a consumer product problem (make EVs attractive to own) than to undo 100 years of car centric building while fighting car and oil lobbies.
It's a "both and" where we should be moving to EVs where feasible and making better cities and towns for non-car transit.

[LongShortLong]

Perhaps, perhaps not. Neither would help your rural problem. I find they also struggle in my urban area. One of the government agencies tracks the MPG of various transit technologies, and my 15 yo hybrid with solo driver beats them all, as do many EVs and some pure ICE options. Trains and buses are inefficient because they are large vehicles that are often empty (deadheading). The personal auto has the advantage that it always carries payload (the driver and maybe passengers). The bicycle even in e-form has weather problems, limited cargo capacity and range, and crash protection problems. The options have their place but the car is king.

As for rural charging, you have electricity right? Home charging is likely more convenient than finding a gas station and constantly tracking tank level. And way cheaper in PNW with your nearly free power. If you're often driving more than 200 miles in a day and going somewhere without chargers, then I suppose that's a problem (backpacking weekends? long ski trips?). Though if you're driving 200 miles you'll pass a suburban/urban area where there's a charger (possibly packed on holidays) or will be soon. Compare those two times a year that a charger is needed vs the weekly trip to a gas station - those two times are longer stops, but less of your lifetime is wasted recharging than refueling. Trading away 52 10-minute gas station visits adds up to an extra ski day.

[neufox47]

I don’t understand this sentiment, EVs get charged at home 90+ % of the time. Where are you going that you need more than 250-300 miles and there are no chargers? I always thought charging for city dwellers who don’t have a dedicated parking space/ ability to install a charger is the hardest population to serve.

Took delivery on our Model Y Performance a little over a week ago. Holy shit that thing is fast. Last fast/fun car I owned was an Audi S4 and this thing is a lot more fun to drive. Making errands fun again (for now).

Power is wicked expensive in SoCal at around $0.46 a KWH. How much to go 100 miles in a model 3? I saw around 35 KW? Are those numbers accurate? So close to $15. My diesel Silverado gets about 25 mpg in city and 30mpg highway. At $5 gallon about the same to go 100 miles here? Maybe my math is jacked up. I lived in Germany and drove an Alfa Romeo 159 diesel, got about 40 mpg in that in a four door sedan about model 3 size.

My folks live in a beach town west of LA (LA County water and power) and pay $0.21 KWH. Superchargers in SoCal are $0.29-0.37 KWH from what I've seen. Anyone paying $0.46 needs to get on solar stat.

Yeah, but the US government isn't spending 770 million dollars this year and ~25 billion on EV and other clean transportation options over the next decade because it's cheaper for you or it drives better.
