2012 Citroen DS5 HYBRID4 stop start

41Hybrid system

Examples of displays


On starting and when stationary

There is no flow of energy (the Stop & Star t system stops and
restar ts the Diesel engine automatically).

Energy recovery

During this phase (deceleration, braking, foot off the
accelerator, … all modes), the battery is recharged by the electric motor/generator, then being driven by the rear wheels.
You can maximise this energy recovery by taking your foot off
the accelerator pedal, deceleration will then be less marked
th
an with a conventional vehicle.

100% electric

In all electric running (AUTO or ZEV modes), only the electric motor, powered by the battery, drives the rear wheels.
The display of "Zero Emission" indicates that the Diesel engine
is off and the vehicle is producing no CO2.

43Hybrid system








ECO OFF switch


This function prevents the Diesel engine
being switched off and so ensures that a comfor table temperature can be maintained in
the passenger compar tment (air conditioning
running continuously).
On pressing the switch, the engine restar ts
immediately.
To return to normal operation, press the switch
a
gain.
After switching off the ignition, the vehicle will
return to normal operation (lamp in the switch
off).
*
Except in ZEV mode, which favours electricrunning over assuring a comfortable
temperature.
During electric running and when the engine is
stopped, the hybrid system manages restarting automatically to assure comfor t levels in thepassenger compartment * .
However, variations in temperature may still
be felt in very hot climates. To avoid any
discomfor t in these conditions you can press
the ECO OFF switch.

47Hybrid system








200 V high voltage battery


The 200 V high voltage battery cannot be
recharged from a mains supply.
The battery is Ni-MH (Nickel Metal Hydride)
and is located below the boot floor, close to the electric motor.
Charging
The battery is charged when the vehicle
decelerates, the electric motor then becomes
a generator and conver ts kinetic energy into
electrical energy (except if the speed of the
vehicle is above 70 mph (120 km/h)).
The battery is not recharged from a mains
supply.
The battery may also be charged automatically
when required by the Stop & Start system of
the Diesel engine.
This recover
y allows the use of "free" energy.
The battery charging time is very short and iscontinuous.
A discharged battery (following ZEV running or
high load, for example) will quickly return to astate of charge sufficient for full operation of the
different hybrid modes.
Thecharging takes place automatically
when driving. The energy recovery can be faster during deceleration.
The average state of charge is 4 to 5 bars, so
preserving a margin for energy recovery when
deceleration of going downhill (free energy).
To preser ve the ser vice life of thebattery, the level of charge never falls below 20 %, even if a level of 0 bars is displayed after ZEV running. Where the battery is close to maximum, vehicle deceleration with your foot off the accelerator pedal will be at a lower level.
