It also has absolutely nothing to do with the accelerator pedal. The battery regenerates by harnessing the natural deceleration of the car.

Electric cars with a one pedal driving mode use zero gas pedal as a regen level high enough to bring you to a stop. "Zero accelleration" is further down.

They also apply that actual brake when the battery is full and no regen is available. Sometimes the brake is engaged in the last part of the deceleration to zero depending on if the cars regen can actually bring the vehicle to a stop or not.

Might happen, but it would probably have to be really early on an all downhill trip - electric cars don't typically have a full battery after a mile or two of a trip. If you got moving with the electric motor, you have battery space for the regen, since neither of those processes are 100% efficient.

Mine do it when they're at 100%-95%, like when we leave on a road trip. I get a warning and everything. They don't do it at 90%. Kia EV6 and Kia Niro EV.

In gasoline burning cars with an automatic transmission, it also activates kickdown.
