The 48V mild hybrid system.

The 48V mild hybrid powertrain system supports the combustion engine, adding electric power during the different stages of driving. Find out more about this innovative fuel-saving system.

Comfort Start.

The mild hybrid system is particularly useful in city traffic, with the Mild Hybrid Starter Generator (MHSG) supporting the combustion engine when re-starting after traffic stops. It supports a faster and smoother engine start with supplemental torque, drawing on energy from the 48V battery.
Acceleration.

Under acceleration, the starter generator supports the engine with 4 to 10 kW of power, depending on the battery system’s charge and the driver's accelerator input. Once the required speed is reached, the system shifts to neutral mode, delivering no power. As a result, CO2 emissions and fuel consumption can be reduced.
Charging while driving.

At a constant speed, the system either is at idle or acts as a generator charging the 48V battery, depending on the battery state of charge.
Recuperation.

In active braking or overrun phases, the rotating crankshaft powers the starter generator, which then recuperates a maximum output of 10 to 12 kW. The generator converts the kinetic braking energy into electricity and feeds it back into the 48V battery.
Extended start-stop.

When coasting at low speeds, the start-stop function activates at 30 km/h. Under deceleration between 30 and 0 km/h, and with the clutch disengaged, the engine is switched off completely.
