Abstract
A control device for an on-board electrical system with at least two batteries which can be charged by a generator and serve to supply various consumers is described. This control device is located between the two batteries and includes a supply network element, a bus-capable microcomputer, a direct voltage converter, and a short circuit proof end stage. The control device is supplied with information via various terminals, and via other terminals the control device can output control signals. As a function of predeterminable data, the on-board electrical system control device closes the connection between the two batteries and after being switched off enters a "sleep mode".
