2011.5 Citroen DS5 HYBRID4 RHD battery

Energy consumption/generation indicator
The indicator dial provides real time information
on the total power used, combining electric and
Diesel.
It comprises three main zones.

ECO zone

Zone which indicates that the vehicle is optimising its energy consumption
, electric, Diesel or a combination of both.
This zone corresponds to phases of electric
running as well as to phases of optimum use of
the Diesel engine, which are easily accessible
with a suitable driving style (smooth "eco-citizen" driving).

CHARGE zone

Zone which indicates that the vehicle is
in electrical energy recovery phase: on ydeceleration, braking or foot off the accelerator, ...
This allows the high voltage battery to be
recharged using "free" energy which can then be reused
for future energy requirements.

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.


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.

Automatic restarting of the Diesel engine or ZEV
mode NOT available
- when maintaining a comfortabletemperature in the passenger compar tment (air conditioning, ...),- when using the vehicle after prolonged parking in a sunny area,- when demisting, - during sustained and sharp acceleration - in mountainous conditions (altitude), - when using the vehicle on a steep slope(car park ramp, ...),- when regenerating the par ticle emissionsfilter, for around 5 to 10 minutes every 300 miles (500 km) (or less for extended urban running. )- in certain engine temperature conditions or requirements, such as an enginetemperature that is too low for the ambientconditions. In ZEV mode, these conditions lead to animmediate change to AUTO mode.The Diesel engine is switched off automatically as soon as these conditions are lifted.
The main conditions are:


- if the gear lever is in position M,

- if the steering mounted gear change controlpaddles are operated,

- if the high voltage battery is not sufficientlycharged. At least 4 bars in ZEV mode soas to provide a cer tain distance (in AUTO mode, electric operation is available morebriefly with a lower state of charge),

- at 18 mph (30 km/h) after setting off (if the internal combustion engine has not already star ted since setting off),

- when the vehicle is on a slope, to retain engine braking from the internal combustion engine when the battery is fullycharged,

- when using engine braking from the internal combustion engine,

- when the fuel level enters the reserve zone(in the event of high consumption of this reser ve, inhibition of ZEV can continue for some time after refuelling).


Your vehicle is fitted with the most effectiveemissions control systems, in par ticular theParticle Emissions Filter (PEF). At regular inter vals your Diesel engine will produce energy for the self-cleaning of this filter.
During this PEF regeneration phase, electric running is purposely made unavailable.

47Hybrid system








200 V high voltage battery


The Ni-MH (Nickel Metal Hydride) type 200 V high voltage battery is located below the boot
floor, close to the electric motor. It cannot be
recharged from a mains supply.
Charging
The battery is charged when the vehicle
decelerates, the electric motor then becominga 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
a state of charge sufficient for full operation of
the different hybrid modes.
The recharge takes place automatically
when driving .
The energy recovery can be faster during deceleration.
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.

This system does not work continuously,
but adapts the force of the fan cooling to the requirements of the battery.
Its operation can be heard at the rear, even if
the vehicle is stopped after a run.
If the air intake is blocked, the battery may
overheat, damaging the battery and causing a
loss of performance of the hybrid system.







Fan cooling of the high voltage battery


For the best use of the high voltagebattery, please follow theserecommendations:


- do not obstruct the air intake with loose articles, otherwise, the battery may overheat, causing aloss of performance of the hybridsystem

- do not spill fluids, as this may cause damage to the battery.


The high voltage battery has an air cooling system, comprising an air intake(located on the side of the left hand rear seat) and a fan (located behind the lefthand boot trim panel).

49Hybrid system

The high voltage battery must not in anycircumstances be charged from an externalsource and must only be handled by a
workshop technician.
There is the risk o
f serious burns, as well as electric arcs that could cause serious injury or
even death.
A used Ni-MH (Nickel Metal Hydride) type
high voltage battery must be removed in an
appropriate manner by a repair workshop,so that its recycling presents no risk to the environment.

High voltage


The voltage used for the operation of theelectric motor is in the range 150 to 270 Volts.
Be sure to take account of the warning labels
fitted to the vehicle.
Ta k e great care regarding the high voltage and high temperatures of components carrying thecurrent.
Emergency cut-off
In the event of an accident, a cut-off system
blocks the high voltage current and cuts off
the fuel pump; your vehicle can no longer be started.To restar t the hybrid system, contact aCITROËN dealer.
Hi
gh voltage cables are routed under the
vehicle (sills); ensure that the vehicle is not
used for off-road activity (such as coveringrough ground) which could damage them.
Be
fore doing any work on the vehicle, switch off the ignition (Readylamp off).



Battery precautions

Hi
gh voltage cables
Take care to position lifting equipment (jack, hoist, ...) at the locations provided to avoid damaging the cables.

Never touch, dismantle, remove or replace the high voltage par ts, cables (orange in colour) or connectors, even in the event of an accident.
