Title: POWER SUPPLY UNIT FOR A UTILITY VEHICLE AND METHOD FOR OPERATING A POWER SUPPLY UNIT FOR A UTILITY VEHICLE
Abstract:
The invention relates to a power supply unit (110) for a utility vehicle (100). The power supply unit (110) comprises a stored electrical energy source (115), a generator (12), and an interface (135) to at least one electrical load (140) of the utility vehicle (100). The power supply unit (110) also comprises a power line unit (145), which is designed to connect the stored energy source (115) and the generator (120) to the interface (135), the power line unit (145) having a switch (150) for electrically isolating the stored electrical energy source from the interface (135). Finally, the power supply unit (110) comprises a sensor unit (155), which is designed to detect a defect in the stored electrical energy source (115), in the generator (120) and/or in at least one line (220) of the power line unit (145) and, in response to the detected defect, to control the switch (150) in order to isolate the generator (120) from the interface (135), in particular the stored electrical energy source (115) remaining electrically connected to the interface (135).
