Charge higher than set battery level?

    Whenever I set my charge (AC charge) to less than 100% (e.g. 80%), let it finish the charge cycle, then disconnect the charger once finished, and turn on the car, I get an alarm and this message: "not charging, current battery level is higher than set target level". However, the car says it has charged to 80%. Also, the little charging indicator light is red instead of green. Which indicates some sort of fault?
    I took it in to the dealer describing the problems and they had to contact the techs back in California, but basically after two days of "working on it" they just "fixed" it by adjusting my charge setting to 100%. I'm not sure if this is something I should be concerned with as this is my first electric car.

  3. The charging indicator (I am assuming you mean the one under the speedo readout that looks like a little electrical plug) does not turn green. I had the same question, took to dealer and they confirmed there was no fault, and that another unit they had on the lot worked the same. Conclusion: documentation error.

    Normal behavior in the morning. Battery charges in the cold night and reports a certain voltage internally. By the morning, the garage warms up and warms the battery or the charging warms the battery. Battery chemistry, thus the voltage, is temperature dependent. It's the reason why EVs in summer get more range than in winter. Whatever the mechanism, the car reports a higher voltage than the 80% setting because the temperature is different than when it stopped charging.

    Nothing is being hurt. Just the car saying it's tummy is a little more full than what it expected.

    For battery health, keep it between 80-20% for the longest life and most practical range. The Kona forums and some discussions here on the Niro forums have the reasons for it. Otherwise have fun, drive it like you would a normal car without stopping at the pump, and welcome to the EV life.

    Thank you! I was so worried I had been doing something wrong.

    Great! I usually keep it between 80 and 20%and only rarely charge it to 100%, that's why I was so miffed at the dealer for fixing it by changing my settings.

  8. My first time in the charging settings, the maximum charging percentage was set to 127%(!) I have not tried to push it back over 100%. I am chalking this up to a software glitch, since my understanding is there extra battery capacity to improve life is around 3 (3.5?) kWh on top of the 64. Has anyone else seen this?

    I got this error in my 2021 Niro EV EX, and the car refused to start. No matter what I did, the car refused to go into run mode and shift out of park.
    Luckily I googled this post, changed the charge limits back to 100%, and voila!, it started right up.

    Anyone else experience a no-start condition like this?

    Nope...thanks for tech...lots of glitches and their offspring (sons of glitches)...

    I get that all the time when I charge to 80% in my 2019. I just say OK a few times and it goes away... Doesn't mean there's a problem.

    Does the temperature dependent charge level account for why, when I charged to 100% this summer, I got a range indication of something like 279 miles? When I first got my 2019 in 12/2019 the max range was 259. This fall I've noticed that the max range has dropped again, but is still greater than the original 259.
  14. Range calculations are also based on recent kwh/mile driving history . I’m not sure how far back the software looks, it might vary from year to year, but it took around 100 kWh, maybe more, before my range readings returnd to “normal” after taking a very long road trip

    As the weather has turned cooler, I have started keeping my car plugged in at night, so have set the charge limit, and indeed get this error every day. Guess it is not something to worry about
