The electronic power supervisor (4)
manages the operation of the two power units,
HDi Diesel and electric, giving priority to low
fuel consumption.
The alternator-starter motor (5) assures
the Stop & Start function, which allows the
HDi Diesel engine to be put into standby when
the vehicle is at a standstill (traffic lights, a
stop, or in a traffic jam...) or during phases of
running in 100% electric mode.
The stopping and restarting of the HDi Diesel
engine is done automatically and instantly
without any action on the part of the driver.
This alternator-starter motor also provides
additional charging of the high-voltage battery
by the HDi Diesel engine, if this not sufficiently
charged, or in 4WD mode for example.
The 12 V battery , located under the bonnet,
powers the vehicle's conventional electrical
system. It is used for starting the HDi Diesel
engine and the operation of the vehicle's
equipment, such as the lighting, wipers, audio
system...
This 12 V battery is recharged automatically by
the high voltage network.
