In order to monitor a functional capability of an accumulator for electrical energy of a battery, at least one position sensor is provided which outputs a position signal which is representative of the position of the accumulator. If the duration of an incorrect position exceeds a minimum duration, an incorrect position signal is output by a monitoring device.

The present invention relates to a battery system having a battery which is designed to supply a high-voltage power system and can be connected by at least one of its high-voltage power system terminals via a contactor (), which battery system comprises a control coil (), and closes in one state in which a control current flows through the control coil, and opens in a further state in which no current flows through the control coil. In this context, in order to generate the control current, the control coil can be connected via a supply circuit () to a supply unit () by means of which a predetermined voltage can be made available which is lower than the voltage generated by the battery. In addition, the contactor or the supply circuit comprises an energy accumulator () which can be charged with a predetermined quantity of electrical energy by means of the supply unit which is connected to the control coil and makes available the predetermined voltage, and in the event of the predetermined voltage being lost, said contactor can continue to generate the control current flowing through the control coil for a first time by outputting the charged quantity of energy.

The invention relates to a safety device (), comprising: a fusible member () having a first segment (), a second segment (), and a connecting segment (), which connects the first segment () to the second segment (). The safety device () further comprises a separation element (), configured to suppress a light arc between the first segment () and the second segment (). The first segment () of the fusible member () extends along a first side of the separation element (), the second segment () of the fusible member () extends along a second side of the separation element () located opposite the first side, and the connecting segment () of the fusible member () extends along a third side of the separation element. It is thus achieved that a light arc between the first segment () and the second segment () of the fusible member () cannot exist even if the spatial distance between the first and the second segment () of the fusible member () is so minimal that it allows a skipping of a light arc.
