Latest Electric Vehicle Technology
Consisting of 180 lithium-ion
cells, the Golf blue-e-motion 30 battery modules can be found in
the trunk floor, under the rear bench seat and between the front
seats. A separate air-cooling system ensures a constant thermal
environment in the battery compartment.
The driver can determine the
amount of energy demanded by the electric pedal from the kW
gauge, which replaces the classic tachometer. A range indicator
is also integrated in this round instrument. The speedometer,
which is located on the usual right side, integrates another
small gauge that provides information on the battery charge
state.
A new feature is the display of
regeneration intensity in the multi-function display (MFD)
between the kW instrument and the speedometer. In battery
regeneration, the driver has the option of pre-setting the
braking energy recovery strategy over four stages via the
automatic gearshift lever or the gearshift stalk on the steering
wheel (D to D3). In the lowest stage (D), the car "sails" as
soon as the driver's foot leaves the pedal, slowed only by the
rolling resistance of the tires and air resistance. In the D3
stage, the maximum amount of kinetic energy is recovered and fed
to the battery. In addition, the electrical energy consumption
of the automatic climate control system and its blower is shown
in the multi-function display.
An active driving profile can also
be set, allowing the driver to select between maximum range,
maximum comfort and maximum dynamics in advance. The selected
profile then pre-configures the power of the electric motor, air
conditioning control, maximum speed and battery regeneration
strategy.
