Regenerative Braking - Fisker Karma 2012 Owner's Handbook Manual

Brakes
Emergency braking
WARNING: Do not pump the brake
pedal; this will interrupt operation of
the ABS and may increase braking distance.
In an emergency, apply full pedal effort even
when the road surface is slippery. ABS will
monitor the rotational speed of the wheels
and vary braking pressure to each
according to the amount of traction
available, thereby ensuring that the wheels
do not lock and that the vehicle is brought
to a stop in the shortest possible distance.
Steering control will be maintained no
matter how hard you brake.
Note: On soft surfaces (powdery snow,
sand or gravel), the braking distance
required by the ABS may be greater than for
non-ABS braking, even though improved
steering would be experienced. This is
because the action of locked wheels on soft
surfaces is to build up a wedge of surface
material in front which assists the vehicle to
stop.

REGENERATIVE BRAKING

Whenever the vehicle is moving and your
foot is off the accelerator, regenerative
braking slows the vehicle and feeds energy
back to the high voltage battery.
By anticipating your stops and simply
removing your foot from the accelerator to
slow down, you can take advantage of the
energy gained from regenerative braking.
The power meter on the instrument cluster
provides real-time feedback on the level of
regenerative braking indicating the amount
of energy being generated and fed back to
the high voltage battery.
The amount of regenerative braking can
vary depending on the current state of the
battery. For example, you'll experience a
reduction in regenerative braking if the
battery is extremely hot or cold or if the
battery is already charged to its maximum
allowable level.
