  1. PSA: Fast Charging derating significantly on hot days

    For my part my thanks to you and this forum for giving me the information to take to the dealer. The technician reported finding "oil" on the high side caps.

  5. High Battery Temp / Powertrain Malfuncion after DC fast charging

  6. High Battery Temp / Powertrain Malfuncion after DC fast charging

    I took a trip from Tucson to Phoenix this past weekend (7-20-2024) Temps in Tucson were 109F and reached 115F in Phoenix. Never DC fast charged before this trip but wanted to use some of my EA 250KwH credit. Battery temp gauge was as high as I’ve ever seen it but stayed halfway between that...
