With Mobile Power to Power Mobile!
Boosting
In boost operation, the electric motor supports the internal combustion engine – the torques of both motor and engine are combined. The power for the electric motor is supplied from an energy storage system.
Downsizing
The electric motor supports the internal combustion engine during acceleration – allowing operation more frequently and for a longer period in a favourable efficiency range. With the addition of power and torque, internal combustion engine sizes can be reduced. This offers consumption, weight and cost advantages.
Downspeeding
With the addition of torque, a higher torque is available already at low speed – in this way the speed of the internal combustion engine can be reduced. Sudden load variations are handled by the electric motor until the fuel supply to the internal combustion engine and its speed has increased.
Recuperation
By means of the electric motor and drive electronics, excess kinetic energy is converted into electrical energy and supplied to the energy storage system. This energy can subsequently be used to drive the electric motor.
Start and stop
In start/stop operation, the internal combustion engine is automatically switched off when the vehicle stops – in this way, no fuel is consumed or emissions produced. The internal combustion engine is automatically restarted with the aid of the electric motor when the accelerator is depressed to move forward.
Auxiliary systems
Auxiliary systems are normally connected rigidly to the internal combustion engine. In this way, speeds of the auxiliary systems – irrespective of the actual demand and independent of the ideal operating point – corresponds to the motor speed. Where auxiliary systems are electric drives, they are only active on demand, can be operated at optimum efficiency and have a virtually constant speed over a wide range.
Emission reduction
Hybrid drives make a noteworthy contribution towards the reduction of CO2 emissions. Potential savings are between 5 and 25 % depending on the type and driving cycle.
