Layout for supplying a vehicle with energy has a generator connected to a vehicle engine, a high-tension bus fed by generator output voltage connected to a high-tension load and a low-tension bus connected to the high-tension bus.

摘要

A generator (2) connects to a vehicle engine (1). A high-tension bus (10) fed by the generator's output voltage connects to a high-tension load (13). A low-tension bus (11) connects to the high-tension bus via a voltage-reducing element (12), a starter motor (3) and a low-tension load (4). A high-tension storage cell's (15) positive connector connects to the high-tension bus and its negative connector is earthed by a switching element (14). A low-tension storage cell's (16) positive connector connects to the low-tension bus by a detachable-key switch (6) and its negative connector is earthed. A control device opens and closes the switching element.
