———————————————————————————
With the EV6, and presumably Ioniq 5, ABRP reports battery temperature when connected via OBDII. This is especially useful since many of both cars don't have battery preconditioning yet. However, the reported temperature is that of the maximum cell, rather than the minimum, which is what drives all charging power determinations. This is confusing many users in the various forums who think they should be achieving certain charging speeds based on ABRP-reported temperature, but aren't because the battery is, in fact, too cold.
