Onboard network voltage regulation method for automobile reduced voltage provided by onboard network when engine is switched off and overall current is below threshold current value

摘要

The onboard network voltage regulation method reduces the network voltage when the engine is turned off, e.g. via a DC/DC voltage converter (D) coupled to the vehicle battery (B), if the overall current (Iges) is below a threshold current value. The voltage can be reduced by 6 V for an onboard supply voltage of 14 V.
