That chart is for LMO battery chemistry (Nissan Leaf) done in 2015-2016 by B. Xu et al. IONIQ 5 doesn't use LMO but SKI 811 pouch cells.
Indeed, the Ioniq5 and the knoa/niro twins allow a maximum to be set, also allow for timed charging to take advantage of off-peak rates, not sure about the Ioniq EV
not all Hyundai BEVs, as i only have the i5 and since last month, my Clarity charges to 85% with the latest app update
I chose not to enroll in Honda's SmartCharge program (it seemed too much like Big Brother to me), so my app can't do the 85% charging.
okaaaay, but you're not doing your battery any favors it's not like everything about you isn't already out there for BB to find... lol
Our Clarity sits undriven for long stretches with between 60% and 90% charge not because I plan it that way but because my wife and I schedule our outings so both of us get to drive our electric MINI. We keep our Clarity for long trips and someday we'll take a long trip again, but we're still nervous.
You never discharge your battery fully and you never overcharge it, just charge when you can , charging to 85% clarity battery is overkill
You can set both AC and DC charging in 10% increments. I only use 100% when going on a trip. The charging stops once you reach the level you set it to.
