Abstract

A voltage supply and drive system for a fire service vehicle or rescue vehicle or special utility vehicle has at least one drive source and having a plurality of voltage sources which are connected to one another by an electrical power system, and a control device. At least one of the voltage sources is formed by a battery, characterized in that the control device is designed to connect or disconnect one or more voltage sources and/or one or more drive sources taking into account at least one emission value of at least one of the voltage sources and/or at least one of the drive sources. As a result, the voltage and/or drive sources which are integrated into the voltage supply and drive system of the fire service vehicle and rescue vehicle or special utility vehicle can be operated, combined in such a way that an overall minimal emission value can be achieved.
