A device for power supply for a vehicle, including: a first battery; a second battery; a fault-detecting apparatus for detecting a faulty state of the batteries; and a switching apparatus having four battery interfaces and a load interface for connecting at least one electrical load to the device. The first battery interface is connected to a first terminal of the first battery, the second battery interface is connected to a second terminal of the first battery, the third battery interface is connected to a first terminal of the second battery, and the fourth battery interface is connected to a second terminal of the second battery. In a normal state, the switching apparatus connects the second battery interface to the third interface, and in an emergency state, the switching apparatus disconnects the second battery interface from the third interface and connects the second or fourth battery interface to the load interface.
