    Wait…
    It’s only for 10-70%?
    I thought the standard was to 80%.
    Maybe there is no standard…
    My car is a 2 min battery that can charge from 20-35% in 2 min.

      In fairness, when I was cross shopping a few years ago ranges were all over the place. 10-70, 20-70, 20-80, 10-90. I do think 10-80 is emerging as a more universal standard but it’s certainly not ubiquitous yet

        Universal standard should be 0-100 tbh, yes it’s not representative of the majority of real world use cases, but it’s the least arbitrary measurement and doesn’t hide anything while also giving people an upper bound of charge time in a worst case scenario.

        All other measurements exist to generate hype

          That would be rather dumb and useless for real world use. Battery charging curves taper off aggressively when you approach 100%.

          My Ioniq 5 can do 10-80% in 18-20 minutes. But the remaining 80-100% can easily take 45 more minutes… So I can get way further, in a shorter amount of time by charging to 80%, driving until at 10% and then charging to 80% again.

          On top of that… For NMC batteries, the charging from 80-100% is where you put a lot of wear on your battery. So if you are at all interested in battery longevity you should avoid charging above 80% as much as possible.

          Here’s some data about the charging curve and amounts of time it takes to charge in different intervals on the Ioniq 5: https://evkx.net/models/hyundai/ioniq_5/ioniq_5_long_range_awd/chargingcurve/

            I think they’re saying the measurement should be for a full charge to give you worst case scenario, which I wouldn’t be opposed to but would still want to know the 80% rate for the reasons you mentioned

              Sure, if all manufacterers included both, that would be nice. But removing the 10-80 to replace it with a 0-100 would be useless.

        I’d rather see a full curve on a chart from 0-100, preferably with multiple curves for outdoor temp variance. -20, -10, 0 10, 20, 30. I don’t want cherry picked data. Give me the full picture, in one picture.
