Avoid Slow Charging In The Cold! Here's Why You Have To "Yo-Yo" Your EV Heading To DC Fast Charge 

WTHeck??

I'm always curious about these things too but being a retired Healthcare professional I know that personal information is on a need-to-know basis. 😊

Maybe she goes to work or school in another city. Their relationship is none of our business.

What do drivers in Florida need to know this?

@@witness1013 without precondition it will charge slower than it otherwise could in Florida too

Owned my Bolt for 2 minnesota winters... done a few winter road trips and HOW DID I NOT KNOW THIS! Thanks! 👍

Nah, I don’t play these silly games with my Tesla.

All these silly games I’m glad I don’t have to do with my Tesla.

I caught that too

that was my first thought too

I picked up on that too! What is happening, the two are such a good couple.

Same here! I caught that too!

Yup, came in the comments for the same question. Kyle what’s going on?!?

She needed the extra space for the doggo's 😄

I was wondering the same thing when She mentioned about her apartment!

My guess is that they moved house ... 🤔

Wondering the same thing 😬 I slow mowed looking for a ring and didn't see anything.

@@Darrenraitt , but she said my garage, not our garage.

@@wrxdrunkie , I did the same thing.

One doesn’t have to precondition battery all time. Only when you want to make long trip and do not have enough charging to hit the road after overnight or longer parking situation.

And, if you are going to need to supercharge, always charge at the end of the day while the car is still warm rather than first thing in the monrning when the car and battery are at their coldest.

They don't because the majority of EVs are built and designed for simple people, not techies.

@@csorrows Sad

Also unnecessary if the car has a good BMS and preconditioning.

We were subzero temps in Ohio for a week about a month ago. When the cold broke and temps got into the 20s and 30s it felt like a spring day at 65..lol

Not all of CA is warm like the media portrayals. I’m currently in South Lake Tahoe. It is 19 degrees.

My gf complains it's too cold when it's 68°.

We should do the reverse, slow accel & regen

I totally agree. I have a Feb 2022 build date EV6 and I’m basically not bothering to road trip right now because 30 kW is way too freaking slow to put up with. Kia of America is straight up incompetent to not be able to incorporate what Kia of Europe did almost 4 months ago. So frustrating.

@@skyemalcolm Absolutely. I sat at 30kW for a good 20 minutes before the car went up to about 60kW, then it bounced a bit before topping out at 115 at the end of the charge. Lucky for me I was able to do a little grocery shopping but I will not be making any road trips either until we get this update. I emailed Kia and got the stock BS response.

@@Datlore001 I’ve emailed them and got no response. I called their help line and patiently explained the problem and asked for a response one way or the other and they never got back to me. That was a month ago.

Due to the 800-volt architecture which has less overall heat loss between the battery and the motor, the technique of "yo-yoing" does almost nothing for the Kia EV6. You really need the battery preconditioning update which will fire up the 5 kW battery heater 30 minutes before you get to a charger. Again, yo-yoing doesn't do much for E-GMP cars. This video is really only for 400-volt class cars.

@@ArtiePenguin1 I don’t agree with this, In the beginning of this winter I drove yo-yo with EV6 came in with 3% charged at 230kW from start but it started to overheat at around 35% and went down to 180kW. So YES you really can Yo-yo a 800V vehicle no problem, but you need work it a little bit harder.

Wow, impressive. Fun to play games with a stupid car.

to be fair, the 1st charge would've heat up your battery already .. not saying that the yoyo didn't help, it certainly helped, but in your condition, it wasn't the only thing that makes the 2nd charge went faster ..

@@baconsledge Yes.jpg

Ev6 comes with battery pre-conditioning right? Or you're sue the firmware update? I got my ioniq 5 battery pre-conditioning update and still didn't feel much difference. Probably I have to check the settings again.

@@Blahblahblacksheep375 go watch is video on ioniq 5 new update and guidelines how to use it.. You can also view ioniq guy channel also for more information

Most cars with no preconditioning and NCM cells work fine if you start with full-ish battery. Highway driving helps the most, but even normal 90km/h roads are enough to warm it up to usable level as you drive. That's the most important thing in my opinion, charge to near full on AC before you need to head out in extreme cold. Also the charging process helps warm it up a bit, especially near 100% when cell voltage balancing kicks in (which is simply extra waste heat). As a practical example, while not that terribly cold - around freezing overnight, I drove 140km over 1.5h (only 20% highways) with my e-208, which used 61% (95 to 34%), with a starting temp of 7°C in the pack (thanks to the AC charging prior) and 18°C at the end. That's 11°C increase, and I'd bet it would be 15˚C extra near the bottom end of the battery and 20-25°C increase if 100% highway too. Even in the worst conditions of -10 or -15°C, the first charge on the way after depleting most of the battery would be at least OK speed (plan a lunch break there maybe) and any further ones would be with absolutely no issue. Especially with higher proportion of highways than what I had. Also at lower temp, the internal resistance of the cells is higher, meaning faster initial warmup while driving. That being said, no preconditioning capability IS a major downside. If you know how it behaves, it's not that big issue, even without having to Yo-Yo, which I'd take as an emergency measure. But it's a fail to lack preconditioning when it comes to the average consumer, ordinary people don't want to become knowledgeable geeks to use their vehicles without issues in any and all weather conditions.

It’s coming in one of the next updates

@@Tomaskom yeah I know driving does warm the battery a bit. My experience with a Tesla is that's just not enough to get great fast charge speeds. Probably chemistry differences

@@dorvinion AFAIK Tesla scavenges the battery heat to warm up the pasaanger cabin, at least the newer TM3 does. That might be the reason why it won't warm up by itself much.

2024 has pre conditioning

Wow that is good analysis .!! I noticed the same that getting more than 125kwh here in NJ when battery Soc is below 20%. Set to 100 but stop at 80 would do the trick.

Are you in a cold weather state?

@@JDDevice New Jersey

Same - 100% agree the charging curve is very steep at lower state of charge, I also get huge difference when below 20% SOC. Have seen 181kW at 12% SOC. Kyle, I like your videos and have learned a lot from them, but this one is a terrible, totally flawed 'experiment', starting at 2 different states of charge and then connecting to a 150 / 350 kW hardware. Also you can get an ODB scanner for $100 and then know the two vehicles' battery temperature. You'dul data to share. Parting thought - it seems like a lot of your videos you rip on ID.4 owners for being uneducated and now you're suggesting they drive completely recklessly for 10 mins before they get to a charger.... feeding the myth.

Regen is limited to a safe amount by the vehicle when cold.

@@dorvinion but it could be limited with the assumption it would be used sparingly only during normal braking. Repeatedly doing high regen on a cold battery may not be caught by software to limit the damage. But this is all speculation, if you own your car do what you want. I wouldn't yoyo my car unless I absolutely had to.

@@SoJa92 Yeah, I agree with you about the regen damage. Instead, if I needed to "yoyo" I would set regen to off which is probably not an option and just use the brake pads to slow down and then speed up to add heat into the battery. And if its not an option, then sell it and get a preconditioning option equipped EV.

@@SoJa92 Without scan my Tesla I can't be sure, but it feels like battery needs to be above 32F before it regens anything. Leaving one EV outside this winter and seems to only Regen 1-5kw... Just enough to offset the cabin heater. Never yo-yo ours because ours does have a battery heater.

@@dorvinion yeah thats what I would expect. In the vid it looked like the id4 was allowing most of its regular regen while cold.

120 hours on a single charge?

@@csorrows thanks. 120 minutes = 2 hours. made the correction.

He did @22:53

@@lemongavine He only said he tried another charger. No mention if it was the same 350kw one. Yo yo driving is definitely unsafe. These tests mostly prove how far ahead Tesla is.

@Lee Oldershaw Why, how is yo-yo driving unsafe? Not being a troll. I honestly just want your opinion.

@@simonthebroken9691 In the presence of traffic or snow contaminated roads it is a bewildering distraction to other drivers and potential cause of loss of control on slippery roads. If all EV drivers did it it would be mayhem. Note the name of this channel.

@@leeoldershaw956 Thank you for the explanation.

Well, it's not like VW has a recent history of blatantly lying to it's customers...hey wait a minute!!!

it would go to 77 if plugged into the charger I assume, otherwise if it went to 77 when not plugged in you would wake up to an empty battery every morning.

I just lost 15% overnight at about 25 degrees F. Something is going on and very annoying because I don’t drive every day.

Yo-yoing the throttle and regen that you have available will heat up the car and allow the limitations to remove at a faster rate

This is even a problem on 50kW chargers where people plug their car in at 0830, walk to the office nearby then come back at 5pm to a fully charged battery but nobody else has been able to use that charger all day long…………….. recently we have had parking wardens monitoring them and issuing tickets but as of 1st Feb locally we will move from free charging to 35p/kW on 22kW and above chargers with a 40 minute timed stay with a £1 a minute overstay fee on their Chargepoint Scotland account - hopefully that will make charging easier for the rest of us who practice ABC and The Out of Spec routing method!

@@timoliver8940 in the Uk, some charge £10/90 mins. After the first 90mins. Maybe call the provider of the charger and suggest this. But yeah I would be screaming. I go up to people an eye ball them if they are over 80% and ask they how long they are going to be. It seems to be the German brand, BMW drivers in particular. They are buying the ix40 and it does not seem to be a road trip car.

The charging curve is always faster when the pack is more empty. That’s to be expected.

@@justinstewart3248 no kidding. I’m talking specifically about this vehicle, however. ID.4 may very well prevent higher speed charging like the 160+ kw that he saw in this video if the charge is initiated above 20%. At least, that’s what I’ve found as a fellow owner. I’m merely hypothesising about battery temp vs beginning battery charge level as the driving factor behind charge speeds for id.4, esp given that the vehicle takes particular pains to notify you of state of charge at the 20% mark.

As an owner of a ID.4 1st Edition (max charging speed is 125kW), the yo-yo method works and definitely come in a low as you can for highest speeds.

I think BMW is now doing that

Think about this too even in Tesla we need it

@@dondaly4773 Tesla's precondition automatically when routed to a supercharger.

@@leeoldershaw956 yea ik but I live about 5 mins from the supercharger it’s be nice to precondition from the app before I leave
