Only trouble is, the cars charge too fast now days! An 800V vehicle like the Ioniq 5 can often be topped up in under 15 minutes, barely enough time to buy a coffee and use the restroom, let alone do any grocery shopping!

And some charging networks apply idle fees if you don’t move your car quickly when charging completes.

Of course, a car can only charge as fast as the charger, so maybe it makes sense (and certainly saves money) to install slightly slower ones at locations where customers are likely to want to spend longer times.



Fast charging degrades the battery. Obviously you will choose a slower charger if you know you will be gone for 45 minutes.

Walmart is also unlikely to have these charges, since they obviously do not want people to rush through their stores. (Obviously charges after a couple of hours might be there.)


> "Fast charging degrades the battery."

True, but in practical terms this is not worth worrying about for most of us. Saw a recent article where a Korean driver had done over 600,000km (~ 375,000 miles) in his Ioniq 5 on the original battery. He'd only ever used DC fast chargers, typically charging to 100%!

His battery did fail around the 600,000km mark, but most vehicles never get anywhere close to that sort of mileage. And apparently it still retained 87% of original capacity up until that point.

And despite being far out of warrantly, Hyundai replaced his battery as a goodwill (good publicity!) gesture.


When do we start jail breaking cars to intentionally charge slowly and avoid fees?


Actually, this is a trick I have used once or twice in the UK while AC charging to avoid idle fees / get cheap overnight parking (shhhhh!).

(Many cars allow you to set a reduced charging speed on AC, but not for DC fast charging, AFAIK)


Don't they slow down past ~80%?
