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.

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.
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).
Be
fore doing any work on
the vehicle, switch off the
ignition (Readylamp off). y

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, orangecables or connectors, even in the eventof an accident.

Underbonnet precautions / warnings
The alternator-star ter motor of your hybrid
vehicle is also supplied at high voltage. If the
vehicle ignition has not been switched off, there
is a risk of the engine restar ting at any time.
Alwa
ys ensure that theignition is switched off ( Readylamp off) before
opening the bonnet.
Also ensure that the ignition is switchedoff when refuelling to avoid the enginerestarting.

Vehicle recovery


Before doing any work, with the ignition on, press the brake pedal and put the gear selector toposition N, then switch off the hybrid system.
If necessary because access to the vehicle is difficult, it can be moved a few dozen metres at a speed not exceeding 6 mph (10 km/h).
Use the towing eyes only to pull a vehicle out or
to pull it onto a flat-bed.

The front or rear wheels must not be on theground, use a flat-bed lorry or trailer to recover
t
he vehicle.
