Hybrid4 system

200 V high voltage battery

The Ni-Mh (Nickel-Metal Hydride) technology
used for the high voltage battery is suited to
the frequent partial charging and discharging
cycles related to the operation of a hybrid
vehicle.
The battery is installed close to the electric
motor, below the boot trim, behind the storage
well.

Charging

The battery recharges automatically while
travelling.
The battery is charged when the vehicle
decelerates and when going downhill, the
electric motor then becomes a generator and
converts kinetic energy into electrical energy
(except if the speed of the vehicle is above
70 mph (120 km/h)).
This recovery allows the use of "free" energy.
The battery may also be partially charged up
to a level of 4 to 5 bars, using the alternator-
starter motor (Stop & Start) of the HDi Diesel
engine.

The average state of charge is 4 to 5 bars, so
preserving a margin for energy recovery when
deceleration or going downhill (free energy).

To preserve the service life of the
battery, the level of charge never
falls below 20%, even if no bars are
displayed on the gauge 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.

The battery charging time is very short.
Once it is discharged, following ZEV running
or high load, the battery will reach its optimum
level of charge after around 10 minutes.

The battery is not recharged from a
mains power supply.

Safety warnings related to high voltage

The voltage used for the operation of
the electric motor is in the range 150 to
270 Volts.
Do not handle the components of the high
voltage system (identified by the orange
colour): risk of electrocution and burns!

High voltage cables are routed under the
vehicle (sills); take care not to damage them
when the vehicle is used for off-road activity
(such as covering rough ground).

Before doing any
work on the vehicle,
switch off the ignition
( READY lamp off).

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 parts, orange
cables or connectors, even in the event of
an accident.

To avoid any risk to the environment,
the high voltage battery must be
recycled in an appropriate manner.
Contact a CITROËN dealer or a
qualified workshop.

Be sure to take account of the warning
labels present on the vehicle.
Battery electrolyte is very corrosive: risk of
burns.
No sparks or naked flames.
Do not burn or heat.
Keep out of reach of children.
Do not spray or pour fluids: risk of damage
to the battery.

Emergency cut-off

In the event of an accident, a safety
system automatically cuts-off the high
voltage system and the fuel supply.
The Hybrid4 system can no longer be
started.
You must then contact a CITROËN
dealer or a qualified workshop.

Operations on the

battery

The high voltage battery must not in
any circumstances be charged from an
external power supply and must only
be handled by a qualified technician
at a CITROËN dealer or a qualified
workshop.
Incorrect handling may lead to serious
burns, as well as electric arcs that could
cause serious injury or even death.

29

Hybrid4 system

This ventilation system does not operate at
the same speed at all times: it is continuously
adjusted to suit the cooling requirements of the
battery.
The noise of its operation can be heard,
particularly at the rear, after the Hybrid4 system
is switched off (post-ventilation).

Ventilation of the high voltage battery

Safety recommendations

Do not obstruct the air intake with
objects such as clothes or bags, in
order to avoid any risk of the battery
overheating, which could cause a loss
of performance of the Hybrid4 system,
even damage to the battery.
Do not spill fluids, as this may damage
the battery and cause a short-circuit.

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

Access to the underbonnet

The alternator-starter motor of your Hybrid4
vehicle is also supplied at high voltage.
If the vehicle ignition has not been switched off,
there is a risk of the engine restarting at any
time.

Always ensure that the
ignition is switched off
( READY lamp off) before
opening the bonnet.

Before doing anything under the
bonnet, you must switch off the ignition
and verify that the READY lamp in the
instrument panel is off - risk of serious
injury!

progressively.

On sharp acceleration in manual mode,
the gearbox will not change up unless
the driver acts on the gear lever or the
steering mounted paddles.
Never select neutral N while the vehicle
is moving.

At very low speed, if reverse gear
is requested, this will only be taken
into account when the vehicle is
immobilised. A warning lamp appears
in the instrument panel screen.
Only engage reverse gear R when the
vehicle is immobilised with the brake
pedal pressed.

This selective gear change mode enables you
to overtake, for example, while still remaining in
automated mode.
) Operate the + or - steering mounted control

paddle.

The gearbox engages the gear requested if the
engine speed permits. A is still displayed in the
instrument panel.

Manual mode

Frequently asked questions

100% electric mode (zero emissions)

Question

Answer

Why is it not always possible for me to select ZEV
(Zero Emissions Vehicle) mode even though the battery
seems well charged?

This situation is temporary.
Certain conditions will occasionally prevent the change to ZEV mode, even if the battery
has sufficient charge, such as, for example, very cold conditions, altitude, demisting, high
demand for heating or air conditioning, regeneration of the particle filter (FAP).

Why do I sometimes see an alert message " Electric
mode not available: FAP regeneration in progress" ?

This is a message which indicates that regeneration of the particle filter (FAP) is in progress.
This is a completely normal process that takes place every 240 or 300 miles (400 or 500 km)
(or more frequently in prolonged urban use), as on a conventional HDi Diesel vehicle.
In the case of a conventional HDi Diesel vehicle, this process is not generally noticed by the
driver.
On the other hand, in the case of Hybrid4 this phenomenon may be noticeable (in urban use)
as temporarily the HDi engine will not stop and this message will be displayed at intervals
while regeneration is in progress.

Why is it not possible for me to put the vehicle into ZEV
mode, even though I had just been running electrically
in AUTO mode?

The management of ZEV is different from AUTO mode.
Changing to ZEV mode is only possible with a battery charge of at least 4 bars, in order to
assure sufficient range.
In AUTO mode, the system alone manages the conditions for changing temporarily to
electric mode, for shorter periods and with a lower state of charge of the battery.

Why is the range in ZEV mode lower when going uphill? The vehicle needs more energy when going uphill than when running on the level.

So it is better to stay in AUTO mode, which will favour operation of the HDi Diesel engine.

Why is it that the system makes me come out of ZEV
mode; it does not return to ZEV mode automatically
when the conditions allow?

It is not intended to give preference to ZEV running at any cost, as it is not always the
most economical mode.
So the system returns automatically to AUTO mode.
