If you have Tesla software 2025.44 or newer, you must update your CPC to V4.05.01 for the CPC to work. This Tesla update broke the CPC, and this update fixes it!

August 12 2025:

V4.04.03 of the CPC now offers a Voltage Model for power limiting - negating power dropoff as the state of charge depletes. The current limit self-adjusts based on a battery state of charge and temperature with a model that estimates battery internal resistance, and the resulting battery voltage sag under high current draws. Using this formula, a current limit is set to match the predicted battery voltage for a target power output.

V4.04.01 has been added, which fixed a UI glitch that some users have been reporting.
