Electric motor

The hybrid vehicle system uses an electric motor to improve the performance of the combustion engine (acceleration, starting, etc.).

The vehicle has more acceleration torque available while consuming less fuel.

The vehicle provides more acceleration torque while consuming less fuel.

The vehicle uses energy stored in a high-voltage traction battery.

■ Battery

The hybrid vehicle is equipped with two types of battery:

• High voltage traction battery
• 12 volt battery

▶ High voltage traction battery

This battery, located underneath the rear floor, stores the energy required for the electric motor to operate correctly.

As with any battery, it discharges when it is used. The traction battery is charged:

• during the vehicle deceleration phases;
• when the combustion engine starts automatically in order to act as a generator.

Your vehicle range in electric operating mode depends on the charge level of the traction battery, and also on your driving style and the components consuming energy (air conditioning, heating system, etc.).

In the event of traction battery discharge, the combustion engine alone moves the vehicle until the traction battery is sufficiently recharged.

▶ 12 volt battery

The 12-volt battery, located in the lower part of the luggage compartment, supplies the energy required to open/close the vehicle and to operate the equipment.

Note: The 12-volts battery does not participate when the engine is started. The vehicle is started by the hybrid system.

■ High-voltage electrical circuits

The high voltage electrical circuit can be recognised by orange cables 6 and parts bearing the symbol.

■ Noise

The hybrid vehicles are particularly quiet in electric operating mode.

You will not yet necessarily be used to it, and neither will other road users. It is difficult for them to hear your vehicle when it is moving.

As the electric motor is silent, you will hear other noises that may seem unusual (aerodynamic noises, tyres, etc.) as well as noises due to the operation of the hybrid system (e.g. cooling of the traction battery).
