Ionna charging is not representative of experience

Bug Reports

Charging time for the Corsicana, TX Ionna station is not representative. When using ABRP to plan stops for my Rivian R1S, I get charging rates that are roughly 1/3 of what I actually experience. For example, On 11/26 when I arrived, I had 22% SOC, coincidentally what ABRP projected. I had a 25 minute charging stop and added 48% to SOC in the same time. However, ABRP projects adding only 15% to SOC. I put in the max charge rate for my R1S (215 kW) for the ABRP calculation. Somehow, ABRP is not treating Ionna charging with 400kW max chargers properly.

Where does this happen?

    Linked is the planning link. For reference, I did arrive at 22% at the first Ionna link, charged for 25 minutes, and left with a 70% SOC. The plan is deficient at 25 minutes and leaving with a 53% SOC

        My colleague has looked at it and from our reports from charging at Ionna stations, it seems like we should be pretty accurate. He also asks if you are not preconditioning on the way to the charger? Too cold or too warm will slow the charging down quite a lot.

    Hi

    Please add a link to a plan where you experience the wrong charging time. Click at Share plan and Share ABRP link.
