The charging connectors 1 enable 3 types of charging:

Domestic charging in mode 2 using a domestic socket and associated charging cable 7.

Accelerated charging in mode 3 using an accelerated charging unit (Wallbox).

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 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.
