– 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
