Vehicle i.e. motor car, has onboard sub-networks provided with electrical onboard network batteries and linked over electrical path, which comprises coupling resistor larger than conductive resistor between generator and one battery

摘要

The vehicle has an onboard sub-network (1) with an electrical onboard network battery (E1), a starter (S) and a generator (G). Another onboard sub-network (2) is provided with another electrical onboard network battery (E2). The former onboard sub-network comprises an electrical conductive resistor (R1) between the generator and the former battery. The onboard sub-networks are linked over an electrical path (3), which comprises a coupling resistor (R2) larger than the conductive resistor. A coupling element i.e. switch, is electrically connected in series with the coupling resistor.
