energy or to charge the traction battery.
► During the acceleration phases, the electric
motor provides an additional boost to reach
the torque needed as fast as possible and to
improve the acceleration at low speed.

Charging cable
► During the deceleration phases, the electric
motor charges the traction battery, using the
inertia of the vehicle.
The charging connectors 1 enable 3 types of
charging:
8. Driving mode selector
9. Domestic charging cable
► Domestic charging in mode 2 using a
domestic socket and associated charging
cable
The rechargeable hybrid technology combines
two sources of energy: that of the petrol engine
and that of the electric motor, which drive the
front wheels (traction).
The engine and the motor can operate
alternately or simultaneously, according to the
driving mode selected and the driving conditions.
The electric power alone provides the mobility of
the vehicle in Electric mode, and in Hybrid
mode in case of moderate demand. It assists
the petrol engine during starting and acceleration
phases.
► The driving in all-electric is possible for
parking manoeuvring, for 20 mph (30 km/h)
speed zones in city, on urban and country
roads with smooth driving and on motorways
in slight deceleration or downhill.
► Accelerated charging in mode 3 using an
accelerated charging unit (Wallbox).
The electric motor is integrated into the
automatic gearbox.
The DC/DC converter provides the link between
the 12 V accessory power supply and the 48 V
traction power supply.
► Superfast charging in mode 4 using a fast
public charger.
The 400 V traction battery 2 uses Lithium-Ion
technology. It stores and supplies the energy
required for the operation of the electric motor,
air conditioning and heating. Its charge level is
represented by an indicator and a reserve power
warning lamp on the instrument panel.
The 12 V accessory battery 3 powers the
vehicle’s conventional electrical system. It is
recharged automatically by the traction battery
via the on-board charger.
The belt starter restarts the petrol engine after
driving in all-electric.
The electric power is supplied by a rechargeable
traction battery.

The heat pump 4 provides passenger
compartment heating and regulates traction
battery and on-board charger cooling.
The on-board charger 5 manages the domestic
charging (mode 2) and accelerated charging
(mode 3) of the traction battery as well as the
recharging of the 12 V accessory battery.
The electric motor 6 provides propulsion in
accordance with the selected driving mode and
driving conditions. It recovers energy during
vehicle braking and deceleration phases.
