Zev Citroen DS5 HYBRID 2016 1.G User Guide

Unsuitable circumstances:



- If the state of charge of the high voltage
battery is lower than 4 bars (equal to
50% charged). In AUTO
mode, electric
operation is possible with a lower state of
charge.

- When the speed of the vehicle exceeds
18 mph (30 km/h), if the internal combustion
engine has not already started at least once
since the Hybrid4 system was started.

- When the fuel level enters the reser ve
zone (illumination of the low fuel warning
lamp). Where this reser ve is is being used
up quickly, ZEV
may not be possible for
some time after refuelling.
- During phases of regeneration of the
particle filter (FAP), which is automatically
triggered approximately every 300 miles
(500 kms) for a period of about 10 minutes.
During regeneration of the particle filter,
the particles a brought up to a high
temperature using the HDi Diesel engine;
A message is then displayed: " Electric
mode not available: FAP regeneration
".



Maintaining the performance of
the system:


- If certain conditions or engine temperature
requirements needed by the HDi Diesel
engine are not met (for example, in wintry
conditions).

- Following a prolonged period with the
vehicle parked in the sun.

- When the state of charge of the high
voltage battery is close to the maximum
level (for example: when going down a long
hill using the electric motor for braking),
recovery of the vehicle's kinetic energy
being no longer possible, the HDI Diesel
engine restarts automatically just to
provide engine braking.

- On a steep rising slope.

- Driving at altitude.

27Hybrid4 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
conver ts 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
preser ving a margin for energy recovery when
deceleration or going downhill (free energy).

To preser ve the ser vice 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.

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 inter vals
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.

43Frequently asked questions

Reducing consumption / Fuel



Question



Answer


How can I optimise my fuel consumption? Give preference to AUTO
mode as it selects in the best way the "driving energy source" to
use in order to reduce fuel consumption.
You should also adapt your driving style to the characteristics of hybrid vehicles to get the
best out of it, for example by taking your foot off the accelerator pedal rather than braking
and by anticipating decelerations which allows the recovery of "free" energy for charging
the battery (entering a built-up area, stop at traffic lights, stop at halt signs, ...).
Why do I not manage to reduce my fuel consumption
even though I often drive in ZEV
(Zero Emissions
Vehicle) mode? It is not ZEV
mode but AUTO
mode that is the most appropriate for reducing fuel
consumption, as it selects the best "driving energy source".

ZEV
mode (100% electric running) can reduce fuel consumption in some cases. However,
recharging the traction battery has an energy cost.
This is why we recommend using AUTO
mode more often.
Why does the fuel consumption histogram sometimes
display consumption of 28 mpg (10 litres/100 km) in
town? In traffic jams, the fuel consumption graph may temporarily display high values but, as the
distance covered is low, this has very little impact on the average fuel consumption.
In urban driving, your Hybrid4 will remain more efficient in terms of fuel consumption
compared to a conventional vehicle.
Why is my battery rarely fully charged? A partly charged battery is normal operation (4 to 5 bars on average in AUTO
mode).
This allows some capacity to be left free for the recovery of energy when decelerating.
Why are there so may fuel alert messages when
starting to use the reser ve? To encourage you to refuel as soon as possible and to avoid loosing the possibility of all
electric running.

Air conditioning / Heating



Question



Answer


It seems to me that the vehicle runs less on electric
when the heating or air conditioning is operating, is that
right? The demand for heating or air conditioning may require the starting of the HDi Diesel
engine until the desired level of comfort is attained.
Normal operation of the Hybrid4 system is simply put back. The period can be longer
under very low or very high ambient temperatures.
It seems to me that when it is very hot and the air
conditioning is working, the vehicle runs on electric for
shorter periods. Is that right? When it is hot, the periods when the HDi Diesel engine is put on standby and the vehicle
runs on electric are necessarily restricted in order to limit the difference between the
temperature in the vehicle and the level of comfort selected.
In very hot weather, it is possible to press the " ECO OFF
" button (which brings the vehicle
out of ZEV
mode and prevents electric running or the stopping of the engine) to give
preference to temperature control (keeps the air conditioning running).

Miscellaneous



Question



Answer


Is towing possible with my Hybrid4 vehicle? For information on the towing ability of your Hybrid4 vehicle, refer to " Weights and towed
loads" in the "Technical data" section.
This allows a jet ski or two-wheeler on a trailer to be towed, for example.
This limit is related to maintaining adequate cooling capacity for the HDi Diesel engine as
well as the components of the Hybrid4 system that are also cooled by the engine's cooling
system.
Why does engine braking seem so strong? If the high voltage battery is not fully charged, the engine braking results mainly from the
energy recovery by the electric motor. The power of this engine braking is higher than that
of an internal combustion engine.
