Honest question

Can the heat/ac be on in the car while it charges?


mkaku t1_j1k0plz wrote

In most cases yes. I often preheat/precool my car while it’s on the charger at home before even leaving the house.


TheyCallMeMrMaybe t1_j1lxkhl wrote

It's good for EVs to do this as well as the AC/heater do significantly reduce battery range.


MovingClocks t1_j1krzjt wrote

If it's anything like the Ioniq 5 the AC will slow it down and if it's too hot outside (TX hot) it may not blow cool air. I usually shut the car down and go hang out inside while waiting.


Sir_Justin t1_j1m2qhl wrote

On what charger? because I've hit 170kw with the AC on. Never been to a 350kw charger before though.


MovingClocks t1_j1m2v45 wrote

150+ kW charger

It's really weather dependent though, if it's just warm outside it's fine, but August with humid weather seems to be too much for it.


orion2145 t1_j1knod5 wrote

Imagine being without AC for TWELVE minutes.


willyc3766 t1_j1kpvoh wrote

I don’t think that’s why they really care. Heating and cooling can use a significant amount of energy in certain conditions. If it’s extremely hot or cold they can heat or cool the car while on charge so that the car is near the temp they want when they start driving. Maintaining that temperature will take less energy to achieve plus it will be a more steady, slow draw rather than a big surging draw if the heating/cooling system had to work at max power.


CyberaxIzh t1_j1mvw24 wrote

The issue is not power. AC takes about 5kW at most, a drop in the bucket compared to propulsion.

It's because AC has to work overtime to cool the battery during charging, so there's no cool air left for the cabin.

I only just got a car that has A/C 2 years ago. I'm a millionaire. Granted that was mostly by choice that I didn't upgrade my 30 year old car, but I still don't have AC on my house. I used to live in Phoenix, AZ., And now live where it still gets 110°F in the summer. I raised 3 kids with no A/C. It wasn't even inconvenient.

Recharging times compared to petrol cars have been one of the biggest objections to EVs, but advances in car fast chargers have made this less and less of an issue.

Nio has just announced a 500 kW ultra-fast charger called Power Charger 3.0 on Nio day. It has a maximum charging current of 660A and can charge EVs based on 800V architecture from 10% to 80% in 12 minutes.

These advances, which should become ubiquitous amongst EVs over the next few years, will mean we need fewer superchargers for long-distance travel, and that EVs will become even more practical for those without chargers at their homes.

A 12-minute charge would make it close enough to filling up a gas tank that they might add them to existing gas stations. Especially companies that have built up the convenience store aspect, they would try to draw people in to make money on higher profit items like snacks and soda.

These things would probably be integrated into a smart grid. Definitely in places which are putting the appropriate priority in managing grids better. EV charging can be an excellent tool for grid stability if the charger is in close communication with the grid.

An example is the UK smart charge point regulations that requires all new EV chargers to be able to negotiate with the grid and defer charging and such.

This is honestly the best take. People (including myself) gripe and moan about accessibility to charging stations and speed and quality etc. But these stations are truly just a supplement. Out side of long commutes and road trips, I don't ever think about charging. I charge at home with a level 1 trickle charge, and sometimes I'll plug in at the grocery store while I shop just to top off.

I think most.people truly don't need a super duper level 100 charger to top them off in 8 minutes. I need chargers that are reliable and actually work when I pull up to them first and foremost. Beyond that I just want a charger that can get me a good chunk back while a grab milk and eggs at the grocery, or a fast and convenient plug and play while I stop at a gas station to use the bathroom and grab a coffee

Yes about 10 years if you only need to charge it twice a week. I think it depends on where you live, a guy on YouTube lives in the mountains of Idaho and especially in winter his driving range gets cut to less than 100 miles in his Tesla. Some batteries are not as good when it's freezing outside. Also, where he lives the speed limit is 80 mph and the estimated ranges are for cars driving like 55mph. They can be a great short range commuter car in a flat and moderate climate, otherwise I think a hybrid makes a better solution.

Convenience. Places where you can create new mid voltage lines from main station and places where people go in mass will rarely coincide.


CptHammer_ t1_j1l7zow wrote

No, a super charging station can slower charge a bank of capacitors. No substation necessary. The amount of time it takes to pull out and pull in a fresh car & hook up doubles the real world time, while your active charge is about 12 minutes.

It seems to be designed to pump out 60A at up to 800V.

So a 600A service is pretty common at 480V for commercial buildings (you can get more I'm just saying this is a really common service). A capacitor bank and a good control unit should make light work of it.

Keep in mind doing fast charging is super bad for your batteries. Also at a local grocery store that has a super charger (they advertise) using that feature costs a few more bucks I'm assuming to discourage it, possibly to get you to shop there and wait longer.

A quick googling says an average nuclear plant generates about 1 GW. That's about 2,000 cars to consume the output of an entire power plant. 500kW is an absurd power draw for a car. We're going to need massive upgrades for the electric grid as EVs become more popular.

Yeah comparing installed power to used work.. slow clap.. Watt and Joule are properly rotating in their graves.

You only need to recharge whatever is used and that isn't all that much more than currently provided by the net.


Those 500kW are also just peak power and will only be required for a few minutes per charging cycle. 500kW flat would charge even an EQS in less than 12 minute from 0 to 100 while in reality you never will see a flat 500kW consumption.

In the end those 2000 500kW chargers will maybe pull half at peak power and that only for a few minutes per day distributes over thousands of square kilometers.

Because no one will need that much one location.

I'm interested in how fast charging infrastructure gets implemented. Charging at 500 kw/vehicle means a service station with 16 vehicles could put 8MW swings on the grid. That's somewhat substantive.

Multiply times a few charge stations and that could impose maximum 100MW swings.on a grid. Now, that's worse case scenario, it's pretty unlikely you go from 200 vehicles charging to 0. The most likely number is probably 20MW swings.

I see each station having a few MW-hrs of batteries as distributed storage. That way the batteries are trickle charged continuously and the peak loading is essentially behind the meter / off grid.

Very true. I think the big time arbitrage options are for vehicles that don't operate much. School buses Tractors / agricultural vehicles Delivery trucks Rental cars / fleet vehicles.

Just think about using school buses to power the grid. They generally don't operate at peak demand (6p in the summer). They are already distributed geographically and would have large batteries.

Most combines only operate 1x per year.

Suddenly these vehicles have an entire new use case.

This is an important piece of the puzzle, but the rest of the grid isn’t ready for this.

Most power sources can’t ramp up/down enough other than hydro and small gas turbines.

Now 5 cars isn't even fast, you would want to actually exchange them faster to have a real advantage over fast chargers.

If you want to do more cars per hour but charge them significantly slower you have to store more batteries.. so half the speed, double the numbers.. but that ain't even slow.. slow would be maybe ten times slower so ten times the batteries.

Now, ULTRA fast charging, 10% to 80% in 12 min. That is awesome but, in the REAL world, there is no chargers like that near you. Only in very modern cities. You will be stuck charging them for like 1-2 hours at a station.

I've been watching a lot of other YouTube channels of people doing traveling in EVs, and it's still pretty bad in a lot of areas. This is not just one area, this is across the country.

We are still in the early ages of EVs over mass market, it will take 15-20 years to be as good and fast as gas cars are. Remember mass market Gas cars came out in the 1908 and it took many years before it was everywhere to get gas.

Are you aware Federal Law requires 8 years/100K mile battery warranties with minimal degradation?

The reason they don't want you to DCFC is they don't want you to realize how minimal the support for DCFC is right now if you don't have a Tesla.

It’s a valid point, but if you’re doing this occasionally for long distance road trips the affect is negligible. Most people do / should charge at home for their day to day travel. The higher cost of supercharging vs. at home charging further encourages this behavior.


Asusrty t1_j1kdzo7 wrote

Effects Of Frequent Fast Charging An electric car’s ability to accept higher charge currents is affected by the battery chemistry. The accepted wisdom in the industry is that faster charging will increase the rate at which an EV’s battery capacity will decline. However, a study conducted by the Idaho National Laboratory (INL) concluded that while an electric car’s battery will deteriorate faster if it’s only power source is Level 3 charging (which is almost never the case) the difference isn’t particularly pronounced.

The INL tested two pairs of Nissan Leaf EVs from the 2012 model year that were driven and charged twice daily. Two were replenished from 240-volt "Level 2" chargers like those used in one's garage, with the other two taken to Level 3 stations. They were each were driven on public reads in the Phoenix, Ariz. area over the course of a year. They were tested under the same conditions, with their climate control systems set at 72 degrees and the same set of drivers piloting all four cars. The vehicles’ battery capacity was tested at 10,000-mile intervals.

After all four test cars had been driven for 50,000 miles, the Level 2 cars had lost around 23 percent of their original battery capacity, while the Level 3 cars were down by around 27 percent. The 2012 Leaf had an average range of 73 miles, which means these numbers represent a difference of around just three miles on a charge.

It should be noted that much of the INL’s testing over the 12-month period was conducted in extremely hot Phoenix weather, which can inherently take its own toll on battery life, as would the deep charging and discharging necessary to keep the relatively short-range 2012 Leaf running.

The takeaway here is that while DC charging may have an effect on an electric car’s battery life, it should be minimal, especially in that it’s not a primary charging source.

I charge at home every night. My car gets almost 300 miles. Most people don’t drive anywhere near that daily. So the only time you need a fast charger is when you go on a road trip.

And using fast DC chargers that infrequently has a negative effect.

True enough if you can charge at home. I think the article referenced fast charging as an option for ppl who can’t charge at home. I would like to know how the occasional fast charging effects battery life, I know for our Lithium battery the charging cycles are stringently controlled so as to avoid quick charges. I imagine all these current issues will be resolved as the technology matures. I would like to consider an ev vehicle as our next car but we would have to add a significant amount of solar and if the car is not there during the 10 AM to 2PM sweet spot, then that causes other issues.

Subaru and Toyota can use superchargers? I thought that was a tesla technology/standard. What voltage traction batteries do subaru and Toyota use?

Still not as fast as filling up your gas tank. And it won't even be full.

Honestly, if your life is so busy that the 7-10 minutes extra time is a deal breaker, fair play to you.

For the vast majority of cases, people can just charge to full at home, or top up every few days, and these fast chargers work fine for that.

Electric cars aren't the answer. And good luck if you charge at home. California is already contemplating charging you more if you charge your car at home and overnight.

I mean I agree, because I don't think cars are the answer in general. But compared to gas cars? Leaps ahead.

Good luck with what? With paying an electricity bill?

If people could afford their gas bills, they can afford the electricity bill lol

You might not want to hear it but that answer was answered about 5 years ago and since then a LOT of people are focusing on building manufacturing resources.

A few minutes that are easily offset by the fact that i only need to visit a gas station to check tire pressure..

A few seconds to plug in and then go and do other stuff rather than a few minutes stood by the car filling it up before i can do the other things i need to?

And "full" is a pointless metric, all that matters is how much range you get.

You are seriously saying staying at the station is better than filling up and leaving? And the fuller you get, the father you go so...

I'm saying i stop to charge and do other things at the same time, like going to the toilet, having some food or whatever i want to do. I mean i don't even need to stop and refill specifically since it's all done whilst I'm doing other things, like sleeping at home or watching a film at the cinema.

Meanwhile you are still at the pump. I'm in and out having done what i need and off whilst you are still having a shit after spending that time at the pump.

Except as i said, I'm not stopping to refuel at all, i have no need to. The only time i would is on long road trips where you need to stop for things like toilet and food.

And if you need to go 20 miles it doesn't matter if you can go further. As long as 80% gives you the range you need, why does it matter that it's not "full"?
