No longer maintain 200+kW charge speeds

On my last two road trips, I’ve noticed a consistent issue while DC fast charging. The charge rate begins at 150 kW, jumps to over 200 kW for about 30 seconds, and then immediately drops back down to 150 kW. During these times the battery temp minimum was over 70F using my OBD2 reader which I thought was fast enough for full charging speeds.

Initially, I thought this was a fluke with a specific charger, but it has since occurred across multiple stations from different charging networks. Previously, the car would reliably sustain charging rates over 200 kW.

Has anyone else noticed something similar?
