Schaeffler has developed a high performance 48V concept vehicle that also offers significant CO2 reductions.
The mild hybrid vehicle provides 20kW of permanent, purely electric performance and features a 48V belt driven starter generator and a high performance 48V electrical rear axle – consisting of an electric motor on the axle - with two gears, capable of producing as much as 2,000Nm of torque.
The 2.1kWh lithium-Ion battery with air cooling is in addition to the 12V battery connected to a DC/DC converter.
In addition, the front axle is powered by a 2.0-litre, turbo-charged direct injection gasoline engine combined with a six-speed dual-clutch transmission.
The electrification of the powertrain allows vehicle functions like electrical manoeuvres and low speed electrical driving as well as fuel efficient engine-off sailing of up to 70km/h, as well as torque vectoring.
The energy generated during braking is fed back into the energy system via the recuperation function that reduces consumption significantly.
Schaeffler's Peter Firsching, senior engineer, said: “Modern vehicles are using less and less fuel, while the vehicle's demand for electricity is increasing due to the greater number of electronic and elctromechanical components.
"Many functions which were previously purely mechanical are now increasingly electromechanical, making 48V hybrid concepts a vital building block in the design of more efficient vehicles with combustion engines that can provide high performance and good comfort.”
