Stabilisation of a vehicle network by generating short-term available power
First Claim
1. A method for stabilizing the supply voltage in an energy-supply system, particularly a motor-vehicle electrical system, which is fed by a battery (1), to which a plurality of consumers (3, 4, 5) are connected, and a generator (2), characterized by the following steps:
- switching on an electrical consumer (3) as a precaution, in order to increase the power supplied by generator (2), and switching off the consumer (3), switched in as a precaution, when a supply voltage falls below a predefined value or would fall below a predefined value by switching on a new consumer (4, 5).

Abstract
The present invention a method for stabilizing the voltage in an energy-supply system, particularly in a motor-vehicle electrical system, that is fed by a battery (1) and a generator (2). If the battery is weak or has completely failed, switching in a new consumer (3, 4, 5) may lead to a voltage dip in the system. To prevent this, it is proposed as a precaution to switch in a consumer (3) not needed at the moment. If, at this point, a new consumer (4) is to be switched in, the consumer (3) switched in as a precaution is automatically disconnected, and the excess energy therefrom is switched over to the new consumer (4).
