2022 Hyundai Ioniq 5 Intro and Preview

There has been much thought and work given to balancing users' demand for fast charging against battery cell longevity with lower charge rates.

Initial heat seems to be a desirable feature and goal to the extent of preheating the cells. Reduced time at those elevated temperatures is also paramount and the task of effective liquid cooling. Learn more here,

Hopefully, the Ioniq 5 has the battery heater and the cooling system to offset the detrimental effects of fast charging.

In the article, you'll see that charging at 60 degC at up to 3C rates does not appear to hurt cycle life of the cells. Hopefully, the 3C rate is not exceeded much or for very long in the 77 kWh battery pack in the US Ioniq 5. The 100+ kWh packs of the longest range EVs currently available would be charging at about 3C or less on the 350 kW chargers.

 

Yes, the damage is already done at lower temperatures. 60degC (140degF) is way, way over the 70degF temperatures at which Li-Ion should be charged.
In efforts to provide fastest charging, demanded by loud & mindless drivers, baby technology Li-Ion chemistry is pushed as if it were bullet-proof.

& don’t think loud & mindless drivers won’t push EV ultra-fast charging past 140degF, when the hot temperatures of summer return. How many Ioniq 5 EVs are being charged in Australia already? Two saving graces, are 1)Australian ultra-chargers are nowhere in the country, yet, & 2) Ioniq 5’s are few in numbers.

 

litesong, you have the right mind set and instincts to do well with any EV and you will baby it for the longevity you desire.

That said, don't close your mind to the rapid improvements that are happening. Safe, fast charging and greater cycle life for the batteries is becoming a reality and solid-state batteries will be another step toward that future. What comes after solid-state batteries, I don't know. I used to think ultra-capacitors were the future, with their quick charge and virtually unlimited cycle capabilities. They are a bit like the solid-state batteries, just without the electrolyte and the hoped-for, greater energy storage.

As far as current and future BEVs go, it is up to the designers and manufacturers to make the batteries last and for them to be dummy (behind-the-wheel) proof. Pyrotechnic hazards and liability are probably greater drivers of car manufacturer behavior than the need to make the cars last a lifetime, so your caution is well placed.

 

Well……Reports are…… that one of the FREE Volta chargers 3 miles from me is not working. Have no idea if vandalism was involved. It appears that the FREE Volta charger only functioned for 2+ months. Vandalism could be a prime cause, specially to a new charger. But, hamhocked & hurry-hurry drivers could wrench the chargers enough to damage them too. I’m still at least 2 months away from getting an EV, probably longer….much longer(?). I was really hoping for much more longevity from the near-by FREE Volta chargers.

12-14–21:
PS…… As I said somewhere else, I had seen a Volta maintenance person taking care of a Volta charger in another city in the region, so it is sweet to know that Volta is maintaining chargers.

 

From 7-27-21:

Banking on FREE L2 charging to help pay for any future EV I may get………..gets its first boot in the dirt….banking!
First, the good news:
One of the FREE chargers I was hoping to use, just got a new charger AND it gives an extra 2kWs of charging per hour!
Second, the bad news:
The FREE charging is no longer FREE. They are charging 40cents per kWhr for their L2 charger…..a price worse than many L3 chargers! I’d like to know the story behind that L2 charger. Bet it has something to do with vandalism.
/////
PS….Another FREE charger that I was depending on for any future EV I got, seems to be giving trouble to multiple EV owners! Well….NOT good news in multiple bits of news!
////
PS I….One nice bit of FREE EV charging news…..Some FREE Volta chargers have reports of supplying MORE than 7kW of power, as much as 8.5kW & 9kW!

 

Instead of gaining their goal of 3000 chargers by the end of 2021, Volta, as of now, only has 2172 chargers.

 

I am so grateful that Wayne, who has accomplished so much in his life, is trying to save me from my future bad decisions.
To be direct, I never will have $40 to $50,000 for an EV. The EV MUST cost $20,000 or less, MUST last 300,000 miles, & the electricity MUST be free. As for the “kick in the teeth” long charging times, I have discovered ways in my beautiful Washington state, to do delightful things while L2 charging. There will be NO “kick in the teeth”. I will be where I want to be & where I belong. The slow L2 charging is the best way to help the EV battery pack to last to 300,000 miles.

 

After 3(+?) weeks of adding no FREE chargers, Volta now has 2221 FREE chargers. I was thinking Volta had dropped off the end of the Earth(wording to allow flat Earthers to understand).

 

The really tough requirement is to pay 3 to 6 times(more?) the local price of electricity to charge battery packs…..& then be happy to do so. You’re right, I can’t meet that tough requirement.

 

Oh, thank you for reminding me that Volta chargers are FREE. I went back to the above post #93, & added FREE to all the Volta “charger” comments.

 

I agree with you. The absolutely astounding thing is that there ARE huge numbers of FREE L2 chargers. WOW! I gotta get an EV….. & be happy with FREE L2 charging. I WILL be happy with FREE L2 charging…..deliriously happy! Think of it. FREE electrons.
Let us now all repeat: “FREE electrons…..FREE electrons…..FREE electrons.

 

Is it good to be rich? I’m not rich & can’t imagine it. But, I can imagine if I do 10,000 hours of what I love to do, while FREE L2 charging, I’ll have as much as 100,000 kWhrs of FREE electricity that will send me 400 to 450,000 miles down the road. “Patience is its own reward” & “It pays to be patient”. I’ve heard of women named Pat, which is sometimes short for Patience.

Previously, I thought I would only have a 7.5kW charger, but the 2022 Chevy Bolt has an 11.5kW charger. So, I think I will get near 100,000kWhrs.

There is one FREE L2 charger 1 mile from our place. I can start charging, walk home & do things for 5 hours, & then walk back & drive home.

I’m so glad to hear that many who love to pay for electricity, will be happy to pay for MY electricity. Thank you, thank you. Know that I won’t waste the electricity, but will efficiently use it.
