VOLTAGE SUPPLY SYSTEM FOR A FIRE-ENGINE VEHICLE OR RESCUE VEHICLE

摘要

The invention relates to a voltage supply system (1) for a fire engine vehicle or rescue vehicle (2) having a plurality of voltage sources (3) that are connected to one another and to a consumer interface (5) via an electrical supply network (4), and a control device (6) and a voltage measuring device (7), wherein at least one of the voltage sources (3) is formed by an alternator (9) connected in respect of drive to a drive motor (8) and at least one further voltage source (3) is formed by a mobile current generator (10) operable independently of the electrical supply network (4). The electrical supply network (4) can be detachably connected to the mobile current generator (10) through a coupling point (11), and the control device (6) is designed to connect and disconnect one or more voltage sources (3) taking into account a continuous measurement of the voltage by the voltage measuring device (7). All or individual voltage sources that are typically carried in a fire engine vehicle or rescue vehicle, including mobile and independently operable current generators, can thus supply the voltage supply system with electrical power.
