When we purchased our 2021 Kona (64kWh ext. range) in Feb 2025, the charging settings were AC: 100% & DC 80%. For the last 8 months or so I've lowered the AC setting to 90% as I've heard that continuous charging to 100% is not the best for the battery, and that last 10% takes almost forever using the 10A home trickle charger. Although there is some ambiguous wording in the Owners Manual about charging to 100% every few months, especially if the battery is regularly discharged down below 20%.
May I ask what are the recommended charge settings among log-term Kona EV owners please?
Thanks, Ian
 
80% to 100% DC charging takes a long time.

I'm lead to believe that 100% AC charging isn't detremental.

But how often do you need 100% charge for a journey ?
