Abstract
A power supply arrangement for a vehicle having an electric motor includes a plurality of high-power batteries which are arranged within the vehicle and are connected to a motor regulator in a series circuit. A switch-off unit ensures that a fixed disconnection sequence is carried out when the motor vehicle is switched off, the motor regulator being first provided with the opportunity of reducing the power drain. Subsequently, a main circuit breaker, which disconnects the connection of the batteries to the outside, is opened first and then further circuit breakers, which are arranged between the batteries, are opened.
