Method for diagnosis of electric vehicle power supply system, involves monitoring voltage of energy source and voltage of energy storage or voltage of vehicle power supply

摘要

The method involves monitoring a voltage (UG) of an energy source (20) and a voltage (U-Bat) of an energy storage (30) or a voltage of a vehicle power supply. A load of voltage of the energy source is determined from the voltage of energy source during vehicle operation or the load is transferred from the energy source. An independent claim is included for an arrangement for diagnosis of an electric vehicle power supply system.
