Depending on the selected recuperation le vel,the
electric mo tor is operated as an alternator when
in overrun mode and during braking in order to
ch arge the high-voltage battery while driving. As
soon as youre lease the accelerator pedal when
th eve hicle is in motion, recuperation in overrun
mode is initiated.
The higher there cuperation, the more sharply the
ve hicle is braked when coasting and the more
electrical energy is fed into the high-voltage bat-
te ry.
