Abstract
In order to monitor an electrical supply system, in particular of a motor vehicle, which is at least partially mounted on a carbon-fiber supporting structure, a monitoring unit is provided and electrically connected to the carbon-fiber supporting structure at preferably a plurality of measurement points. Voltage values are tapped off at the measurement points and compared with permissible voltage values. If the voltage values exceed permissible maximum limits, on account of a short circuit for example, this is judged to be an indication of an impermissible current across the carbon-fiber supporting structure, and a power source is disconnected from the supply system, in particular.
Claims13
An apparatus for monitoring a supply system being at least partially mounted on a carbon-fiber supporting structure and the supply system connecting an electrical load to a power source, via a supply line and a return line, the apparatus comprising:
- a monitoring unit electrically connected to the carbon-fiber supporting structure at at least one measurement point.
A motor-vehicle electrical system to be at least partially mounted on a carbon-fiber supporting structure, said motor-vehicle eletrical system comprising:
- a power source to be connected to an electrical load;
- a supply line connected between said electrical load and said power source;
- a return line connected between said electrical load and said power source;
- and
- a monitoring unit electrically connected to the carbon-fiber supporting structure at at least one measurement point.
A method for monitoring a supply system being at least partially mounted on a carbon-fiber supporting structure and the supply system connecting an electrical load to a power source via a supply line and a return line, which comprises the steps of:
- providing a monitoring unit for tapping off a voltage value at least at one measurement point on the carbon-fiber supporting structure;
- and
- evaluating the voltage value.
