Abstract
A power supply system contains two batteries and a load device which is connected to the batteries such that, upon failure of one of the batteries, the other takes over the supply of power. The batteries and the load device are connected to one another by a single ground line and arranged such that, upon an interruption between the interconnected grounds of the batteries and the ground of the load device, the load device is fed with the difference voltage of the batteries. A reliably operating power supply system is created which is operational by with only one ground line.
