Electric cars?

[Value Collector]

On one hand, great idea.

On the other you know the car has that function but 99.9% of people don't. Most people seeing that are going to assume the dog's in danger in a seriously hot car and some will take action in regards to that.

It's one of those things where technology is ahead of society with that one.

It puts up a notification on the cars display letting anyone that looks in that the car is in “Dog Mode” and tells them the temp.

Leaving your ice car running when you are more than 3m away is illegal.

But more impin an EV you don’t have a huge engine running wasting a tonne of fuel, you just have a small electric motor efficiently running the fans or aircon depending.

Also, cabin over heat protection only kicks in when the temp rises towards 40 degrees, it will first attempt to just use fans to blow in air from outside, but if that is not enough to keep the cabin under 40 it will use the minimum amount of air con to maintain the cabin at 38 degrees.

Cabin over heat protection uses very little energy, where are leaving your ICE car running would be a huge waste, not to mention blowing poison gas as everyone else in the car park.

so yeah, the old ICE cars can’t really do that, at least not efficiently, safely or legally.

ICE cars use vanishingly little fuel at idle:



And an ICE car can use just fans in the literal exact same way an electric car can as the fans themselves run on electricity. It's the A/C which needs the engine running.

I'm also pretty doubtful about the legalities you mention, it might be true for public property/parking on the street but on private property this would literally make it illegal to leave your car running if you forgot your wallet and just ran inside to get it or something, which sounds patently absurd.

Ignoring that entirely, if this was a feature people really cared about, a decent ICE car battery has more than enough juice to run an air conditioning compressor for a while. MORE than enough.


This just isn't something that can't be added to ICE cars if it becomes a selling point. It's nice, but this isn't an electric car exclusive feature.

——————

I will leave that jargon to you, because it seems nonsensical to me.

It's used literally dozens of times a day when discussing investment strategies by, well, basically everyone. I've seen it squillions of times just on this forum alone. Seems odd that I'm the one telling you this TBH?

here is an article mentioning thats It’s illegal to leave your car running.
https://corporatedrivertrainingaustralia.com.au/leaving-a-car-unattended/

we have already discussed the fact that Internal combustion engines lose about 70% of their energy to heat etc, this is no different while idling, ofcourse idling uses less than full throttle, but it can’t compete with a dedicated electric motor that only runs the aircon or fans.

just look at the size of the ICE cars engine, and all the moving parts of the engine, including the water pumps and cooling fans required to remove all that wasted heat just so you can turn the air con compressor vs having a simple small electric motor turning the compressor with almost no energy loses compared to the ice car.

Ignoring that entirely, if this was a feature people really cared about, a decent ICE car battery has more than enough juice to run an air conditioning compressor for a while. MORE than enough.

I don’t think people would appreciate not being able to start their cars at the end of the day because the tiny battery in their ICE car is flat.

people don’t care about this feature until they have it in their lives, it’s a good little luxury, it’s not something you buy an ev specifically for, but it’s one of the many things you appreciate once you have it, like not having to visit the petrol station anymore,

That's about theft and security. By its and your logic, it would be illegal to accidentally lock your keys in your car and go into a shop or something "leaving your vehicle unattended" to call RACQ to come & break into it for you. Absurd.

But I already said the engine doesn't have to be running for the battery to power some air conditioning, and it certainly doesn't need to be running for a battery to run the fans only either.

So even if we accepted your "the engine can't be idling" argument, it doesn't matter, because the engine doesn't need to be idling for the fans and/or air conditioning to be running.

we have already discussed the fact that Internal combustion engines lose about 70% of their energy to heat etc, this is no different while idling, ofcourse idling uses less than full throttle, but it can’t compete with a dedicated electric motor that only runs the aircon or fans.

Twice or even three times zero is still zero.

ICE engines use vanishingly little fuel at idle. The proportion becomes irrelevant when we're talking multiples of nearly nothing.

I don’t think people would appreciate not being able to start their cars at the end of the day because the tiny battery in their ICE car is flat.

It won't be. Like I said, an ICE car battery has more than enough capacity to run the air conditioning for five minutes (or whatever) before you get in the car.

I don't think you realise how much fan and/or air conditioning running time a normal car battery actually has in it.

people don’t care about this feature until they have it in their lives, it’s a good little luxury, it’s not something you buy an ev specifically for, but it’s one of the many things you appreciate once you have it, like not having to visit the petrol station anymore,

I'm going to continue using the terms in the same way that absolutely everyone else understand their meaning and therefore use. If you choose to interpret them in a way other than how you know I and everyone else mean it, that's on you.

Everyone else know what I'm referring to, oddly enough.

Well I wasn't expecting they'd thought of that one!

(Seriously, for any other car it's a very real problem - people leave animals in hot cars and they die yes).

 

[Smurf1976]

I don't think you realise how much fan and/or air conditioning running time a normal car battery actually has in it.

For the A/C literally zero since, in most cars at least, it's driven from the engine and is not electric. There are exceptions, cars with electric A/C, but that's not what the average car has.

For the fan, in theory a few hours as long as it's only the fan you're using. That said, I've only ever driven one ICE car that lets you turn the fan on with the key in "accessory" position and none which allow running the fan without the key in the ignition.

As for idling engines, did that for an extended period once (10 hours or so). It was for a reason, power was being tapped off the 12V and far more current than the battery could supply without going flat, so running the engine was the workaround.

All good, seemed to suffer no harm but then when I got in the car and drove off after it had been idling all day there was an almighty cloud of black stuff which came out the exhaust.

5 minutes???
cabin over heat protection needs to be able to run for 5 hours.

what’s the point of having a cabin over heat protection if it only keeps your car cool for the first 5 minutes of your 8 hour work day?

this is what I am talking about, the standard lead acid battery will not hold enough charge to keep run the air con for any practical length of time and still be able to start the car, especially once that battery is 2 years old.

And as I've demonstrated, it's not something unique to electric cars, making your point irrelevant.

Have you? Which Ice cars have this feature.

ICE engines use vanishingly little fuel at idle. The proportion becomes irrelevant when we're talking multiples of nearly nothing.

Firstly 600mil per hour is not nothing, and as that guy in the video said, even the cars manufacturer testing says it’s higher than that.

secondly, that’s is for an engine with no load, as soon as you put the aircon on in an ICE car you can hear the engine begin to labour more, increasing fuel consumption, so it could be easily over 1 litre and hour probably closer to 2 litres for the average size engine.

so that’s consuming up to $3 of fuel per hour.

which means when I parked my car outside yesterday (Hot Queensland day), I would have burned about $15 of petrol vs $0.45 of electricity, I don’t think people would want their engines running burning cash like that.

I'm well aware of how it's driven currently, same as I'm aware that the key needs to be in the accessories position in order to turn the accessories on.

I'm saying it can be added to ICE cars very easily if it becomes a selling feature. In fact, it could have been added to ICE cars years and years and years ago, so either none of the ICE manufacturers thought of it, or it's a pointless gimmick.

5 minutes???

No it doesn't?

If it takes ten minutes (or whatever) to cool the car down from whatever temp it is in the sun to a comfortable temperature to get in to, then it needs to run for ten minutes.

It only needs to run for the amount of time necessary to bring the car down to whatever temp you've decided.

what’s the point of having a cabin over heat protection if it only keeps your car cool for the first 5 minutes of your 8 hour work day?

Er, what?

Why would you be cooling your car when you're not in it?

this is what I am talking about, the standard lead acid battery will not hold enough charge to keep run the air con for any practical length of time and still be able to start the car, especially once that battery is 2 years old.

You're defining practical level of time as hours. Why would you be cooling your car when you're not in it?

Have you? Which Ice cars have this feature.

The feature is not unique, it can be (could have been years ago) added to ICE cars any time the market actually wants it. You're acting as if this is something that ICE cars can't do rather than something they aren't doing, which are completely different things.

Firstly 600mil per hour is not nothing, and as that guy in the video said, even the cars manufacturer testing says it’s higher than that.

Yeah but you're not running the car at idle for hours are you? You're running it for 5-10 mins before you get in it. So burning 60ml (depending on engine size), or about 10c, of fuel.

secondly, that’s is for an engine with no load, as soon as you put the aircon on in an ICE car you can hear the engine begin to labour more, increasing fuel consumption, so it could be easily over 1 litre and hour probably closer to 2 litres for the average size engine.

I think if you leave your car parked with the air conditioning running for the entire day without anyone actually in the car, you're a moron.



Can someone please explain this premise of leaving the air conditioning running for hours and hours and hours at a time without anyone actually in the car? Why would anyone do this?

As best I can tell, you just want to keep the car cool for a few MINUTES either when you leave the dog in the car or you want it to be cool when you get back in it, so you just fire up the air conditioning ten minutes before you finish work and get into a nice cool car?

I genuinely can't understand this whole "it needs to be running for hours" thing?

 

[Value Collector]

If it takes ten minutes (or whatever) to cool the car down from whatever temp it is in the sun to a comfortable temperature to get in to, then it needs to run for ten minutes.

The point of the cabin over heat protection is to protect the car and its contents from damage and premature deterioration caused my constantly exposing the interior to super high temps, so turning on for 5 to 10 minutes doesn't quite cut it.

Er, what?

Why would you be cooling your car when you're not in it?

As explained above, "cabin over heat protection" just keeps the car below 40 degrees to protect the car and its contents, exposing the car and other equipment to 60+ degrees temps is not good.

You're defining practical level of time as hours. Why would you be cooling your car when you're not in it?

Let me explain the various modes.

1, Cabin over heat protection mode - Stops the car exceeding 40 degrees for the protection of the car and sensitive things like phones you may have left in it.

2, Climate control - Brings the car down/up to what ever temp you decide before you arrive back at car or you can leave it on to protect groceries etc.

3, Dog Mode- Keeps the car cool/warm for Rover while you are temporarily away

4, Camp mode- like Dog mode for people, but also allows entertainment and arcade features to operate

The feature is not unique, it can be (could have been years ago) added to ICE cars any time the market actually wants it. You're acting as if this is something that ICE cars can't do rather than something they aren't doing, which are completely different things.

Ice cars can't run cabin over heat protection for any practical time.

Also, its a bit like saying Ice cars could have added self driving and sentry modes, so Tesla isn't unique, the fact is they didn't add those features, so Tesla is unique.

Yeah but you're not running the car at idle for hours are you? You're running it for 5-10 mins before you get in it. So burning 60ml (depending on engine size), or about 10c, of fuel.

As explained above, cabin over heat protection runs all day every day when ever they car is going to go over 40 degrees, and doesn't require a massive engine idling, it just intelligently turns on and over, nothing like that exists in Ice cars.

I think if you leave your car parked with the air conditioning running for the entire day without anyone actually in the car, you're a moron.

At this point I think you just don't understand the cabin overheat protection mode, it turns on and off as needed, its you that was saying you could replicate this feature by leaving your car idling, which would be moronic.

Can someone please explain this premise of leaving the air conditioning running for hours and hours and hours at a time without anyone actually in the car? Why would anyone do this?

Hopefully by this point I have repeated my self enough times for you to understand that cabin overheat protection mode runs all day to keep the car below 40 degrees, but aircon only switches on and off as necessary to keep it below 40degrees which is still fairly warm, but its low enough to prevent undue damage or deterioration to you car and personal bellowing left inside the car.

Remember - It was you that suggested ICE cars could achieve this by leaving their engines idling to run the aircon, not me.

I think the only reason you find this feature weird is because you are thinking like an ICE car owner, where in the back of your mind running the aircon is a cumbersome and expensive exercise, so it seems simpler to just let your car bake all day cooking the inside, where as once you have an EV you will see have a feature that protects the car and its contents by intelligently switching the fans and aircon on and off every now and then is simple and low cost good idea.

I have to say I am very impressed with the cabin cooling technology of Tesla cars to cheaply and easily :

1) Protect the interior of the car from temperature extremes on hot days
2) Cool the car before you get into it
3) Protect an animal and have a big screen telling people the internal temperature and what is happening

One wouldn't necessarily buy the car because of these features but wow what a bonus. And really I don't believe it would be anywheere near as practical/viable to attempt a similar exercise in an ICE car - unless they were a hybrid and somehow had integrated this technology into the electric components of the car. (And I don't think that would work because the A/C I suspect would be operated through the petrol motor)

There is often more than just floor mats in the car.

Lets take the iPhone for example, its a common thing people leave in their car, Apple don't recommend exposing it to temps above 40 degrees, But a car with no cabin overheat protection left in the sun can have temps rise to 116 degrees, now if you think thats good for the growing amount of electronics modern cars have, by all means avoid over heat protection (you can switch it off if you like).

Its also not just electronics, heat speeds up the rate of deterioration for all sorts of trimmings and especially leather which will dry and crack faster if exposed to heat, Tesla is focused on producing 1,000,000 mile cars I think they are playing the long game here, helping peoples cars look good for longer, while also protecting their gadgets and other stuff.

As I said sometime it also comes in handy to be able to leave a cheese cake in your car for 40 mins and have climate control cool the car while you duck away for a last minute thing, You never know till you need it, and like anything once you have these options, situations always seem to pop up.

If by that you mean that I think that anyone who buys an electric car because it has "cabin overheat protection" is an idiot, then yes.

The only reason to run the a/c when you're not in the car would be to leave a pet in it or to cool it down before you got in it, both of which would only ever be a few minutes at a time, meaning that it could be run off a normal car's battery if this kind of thing actually mattered to the market, meaning that it would have been added to ICE cars years ago if it did. Ergo, it's a gimmick.

As a car guy that's been fiddling with cars as a hobby with more mods, engine conversions, tune-ups and everything else you can imagine for 13 years and counting now (so, you know, someone that actually knows a thing or two about cars), I can assure you, anyone who buys an electric car because it can keep the floor mats cool when you park it in the sun for several hours (like an idiot) is an absolute moron.


This is not a selling feature, except to idiots.

 

[Value Collector]

If by that you mean that I think that anyone who buys an electric car because it has "cabin overheat protection" is an idiot, then yes.

This is not a selling feature, except to idiots.

Perhaps you should drive around yelling at the people that take the shaded car parks, telling them they are idiots for wanting their car shaded and cool because there is no benefit in it, because the first car parks to fill up are always the shaded ones, that shows a certain amount of people do think about their car cooking in the sun.

Hell the only reason I brought it up in the first place was because I was talking about the other car with the solar panels on it, and I said at least the solar panels would provide some charge to run your cooling if you have to park your car in the sun, I have never said its a selling point.

I don't think most people are aware of the feature until after the have bought the car and start looking through the settings, its not like it is advertised anywhere, its hidden in a setting menu some where.

But ask your self this, if you did own a brand new Tesla (or other electric car) which comes with the Cabin over heat protection switched to on as standard, would you purposely go and switch it off? or would you think it has some value to leave it on through our scorching Aussie summers to prevent you nice new car baking? go to any parking lot and you will see the shaded spaces are always the first parking spots to go, so people obviously think about their cars getting cooked.

as I said I think you maybe just don't see the value in it because you have never had it, I am not saying its something you buy a car for, I said it one of the million little bonuses you realise EV's have that are good ideas that

Over9K's next rant - The Evils of shade cloth in carparks and how people that park beneath them are idiots,....HAHAHA

 

[over9k]

Alright so I'll try to be a bit more diplomatic here:


It isn't heat per se that ruins cars, it is direct sunlight which does it. Take a look at any old leather car and just take a look at the difference between the front seats and the rear seats. Now the front seats get more use and wear from that use, but take a look at the actual leather itself, not the wear points on the seat bolsters, but the actual leather itself. You'll see that there's an enormous difference in the leather between the front & rear of the car. You'll also see how things like the dashboard very often end up cracked whereas the door trims are absolutely fine, despite being made of the same stuff (leather, alcantara, plastic or otherwise).

So with that in mind, think about where the sunlight gets into a car, and then see how the more sunlight gets to a part, the more annihilated it is. You'll see how the rear footwells & door trims are the best, then the rear seats, then the front seats, then the dashboard will be the worst (assuming everything has the same trim). This is not a coincidence.

It is also particularly pronounced on cars with tinted windows as you have a vehicle in which the sunlight comes through the windscreen completely unfiltered but with an enormous amount of protection on all the other windows/glass areas of the car. The interior temperature is going to be sky high everywhere as the interior is so small, but the front of the car and the dashboard in particular is getting absolutely smashed by the sun.

This is also true of paintwork - simply being hot won't do a damn thing to a car's paint, but a significant amount of time in the sun will absolutely obliterate it. Even faster than it will ruin the interior. If I could park my car in an underground carpark on a 40 degree day vs park it in the sun on a 20 degree day, I'll take the underground carpark every single time.


The best thing you can ever do to protect a car's aesthetics/comfort is to simply not park it in the sun in the first place. That's it. Just don't do it. But if you have to, you need to do everything you can to keep the sun out of the car. Not the heat. The sun.

The first thing to do is get the windows tinted, which is a factory option on absolutely everything, ICE and EV's alike. Even ignoring this interior protection entirely, tinting the windows will make a massive heat difference to the vehicle just from a passenger comfort perspective. Modern UV films etc are extremely technologically advanced and block out far far more heat, UV rays etc (heat is well past 50%, UV rays are 100% like with sunglasses) than just the 35% light reduction they do. They are not a gimmick. I'd go so far as to say that on account of the sun danger (skin cancer rates etc) that this country has, every car should have tinted windows in Australia and they should actually be mandatory (standard) on every new car sold.

The next thing is to get one of those sun-reflecting dashboard protectors that you unfurl and mount up against the windshield. They look like this:



And you can obviously see how they work.



What I'm trying to say here is:

Don't go buying a tesla thinking that this "keeping the air conditioning running" feature will save your car's interior by "only" letting it get to 40 degrees if/when you leave it in the sun. It will not.

If you're thinking that buying a tesla with this feature will enable you to leave your car parked in the sun without ruining the interior like doing so will with an ICE car, you are mistaken. You will end up with a very rude surprise.

Like I said, if you absolutely have to leave your car parked in the sun then get the windows tinted (if they aren't already) and block the windshield off. That's all there is to it.

The other thing to do (especially if the windows are tinted, which they already should be completely irrespective of interior protection) is to park it so that the rear of the car is facing towards the sun (or where the sun will be) as you'll have either a tinted rear window blocking the rays or worst case, a much smaller rear window letting them in when compared with the windshield.

This seems like the simplest thing in the world, but you'd be amazed how many people just never even think of it.


Air conditioning isn't shade. They are very different things.

 

[basilio]

VC follow up question regarding the internal temperature control on the Tesla.

Is there, to your knowledge, a back up plan if the cooling system fails, particularly if its in dog mode ? For example will the car send a message to the key fob or connected IPhone to warn you that cooling has gone south ? Would the windows automatically crack open to ventilate the car in such a situation ?

And also. Does this temperature control work to keep it warm? For example if it particularly chilly outside can the internal temperature be kept up to a reasonable level ?

 

[Value Collector]

Alright so I'll try to be a bit more diplomatic here:


It isn't heat per se that ruins cars, it is direct sunlight which does it.

No, you are wrong. its both light and heat, a main way light causes damage is because when the photons of light hit a surface it generates heat that builds up on the surface and over time breaks that surface down, keeping an area cool will minimise damage.

If you don't believe me here is an article from the western Australian museum about causes of deterioration.

Deterioration

The principal agents of deterioration of textiles are:

• light;
• temperature and relative humidity;
• pollutants and chemical degradation;
• dust;
• inappropriate repairs and handling; and
• biological deterioration (insects and mould)

Substances incorporated in finishing and manufacturing processes may contribute to textile degradation. For instance, metal-based dyes and dye mordants can accelerate rotting of fibres, producing gaping holes in affected fabrics. In silks the weighting, which was introduced in the form of metal salts to increase the weight and make the silk crisper and more drapable, actively promotes the degradation of the fabric. There is little that can be done for these fabrics as deterioration will continue even under good storage conditions.
Light
All forms of light are damaging to textiles. Photochemical reactions initiated by light energy can lead to the deterioration of the principally organic textile components. The damage to a textile by visible and invisible radiation is cumulative and irreversible. Of particular importance is the ultraviolet (UV) radiation band which supplies enough energy to break the molecular bonds found in textile fibres. UV radiation is present in daylight and is also emitted by many types of artificial light. Control of visible light and UV radiation is described in an earlier chapter (see the chapter Preventive Conservation: Agents of Decay).
Closely monitor and limit the amount of light to which textiles are exposed, particularly those on display. Storing textiles in the dark is standard practice.
Isolate light sources from textiles because heat generated from light sources can accelerate deterioration. Most light sources generate heat and this can build up, especially if the light source is housed in the same closed cabinet as the textile.
Temperature and Relative Humidity
Do not expose textiles to high temperatures. Often the effects of heat damage are not immediately obvious but may be manifested by fibres becoming brittle or discolouring.
Relative humidity is a well understood agent of destruction. Fibres expand and contract in line with changes in relative humidity. Continual fluctuations of this type create stresses in fibres which may eventually lead to fragmentation of the textile. Under low relative humidity conditions fibres shrink, textiles become desiccated and lose flexibility. They are then more susceptible to damage when handled. If on the other hand the textile is exposed to high relative humidity conditions then the chemical stability of the textile will be threatened, the effects of light exposure enhanced and mould growth and insect attack encouraged.

Jesus christ I am arguing with reddit.

I never said that the air conditioning won't help, I said that the interior is still going to be wrecked by the sun anyway. I even made a very big point of explaining how the front (where the sun is) of a wrecked interior will be much worse than the rear (where the sun isn't) despite the air in the car being the same temperature and even mentioned the cooler but sunny vs hotter but shaded hypothetical. The main killer of the interior is sun, not heat. Ergo it is the sun that you need to deal with somehow.

Simply cooling the interior will not be enough to protect it. If you think it will, you are in for a very rude surprise.

I never said that the air conditioning won't help, .

No, you just said people that use it are morons, and tried to make out having cabin over heat protection was crazy, which it clearly isn't.

I never said that sun visors won't help either, but if you are forced to park in the sun, why wouldn't you want to run cabin over heat protection? I mean if you have it why not use it, I'm obviously not saying avoid shady spots or sun visors, but in situations where you are forced to park in the sun, the cooling is going to help.

-------------------
This is my last post on this topic, all I will say is that I didn't promote over heat protection or say its a major selling point or cure all, I just said it exists, then you started flipping out saying its crazy and stupid and you can just idle your car etc etc.

My point stands, EV's batteries and electric driven cooling and heating mean they have simple ways to manage cabin temps that have benefits in a wide range of situations, which is just another one of the many slight benefits EV's that add up, no need to flip out about it, and I believe you would use it if your car had the function.

-------------------

Now should I mention that another slight benefit (not a selling point) is that EVs will also continue charging your phone even when the car is turned off,... no I won't because we all know you can just leave your ICE car idling or in accessories or some future ICE manufacturer could just build in that feature, and only idiots think thats a selling point anyway. hahahaha
