Switching arrangement and process for switching off an electric energy source of a vehicle

摘要

A switching process and apparatus for switching-off an electric energy supply of a vehicle has two switching elements which are mounted in the proximity of the electric energy source, and couple it to supply electric energy to consuming devices of the vehicle. In the event of a fault, an all-pole switch-off is implemented by opening both switching elements. One of the two switching elements is an operating switch by means of which the electric energy source can be switched off in normal operation. In the case of a vehicle driven by an electric motor in a normal operation the driving current of the electric motor is first controlled downward, and the operating switch is then opened when the driving current is decreased.
