Regenerative Braking

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

The regenerative braking is a software strategy and is controlled by the ABS module, the PCM and the BECM. Regenerative braking is the ability to capture and store a portion of the energy that would be lost as heat during a braking event. When the driver applies the brakes, the PCM determines how much negative torque (braking force) the electric motor should provide in addition to the friction brakes. Depending on the high voltage battery state of charge, the amount of negative torque provided by electric motor can vary between 0 and 100 percent. The electric motor then becomes a generator, which causes the energy to flow into the high voltage battery. The PCM strategy smoothly blends regenerative and friction brake effort to make the dual brake operation transparent to the driver.
