Patent ID: 10071646

Abstract:
The disclosure relates to an electrical system for a vehicle, comprising a low-voltage sub-network for at least one low-voltage load and comprising a high-voltage sub-network for at least one high-voltage load and an electric generator. The high-voltage sub-network has a battery which is designed to generate a high-voltage and output same to the high-voltage sub-network and which has at least two battery units with individual voltage taps. The high-voltage sub-network is connected to the low-voltage sub-network via a coupling unit which is designed to draw energy from the high-voltage sub-network and supply said energy to the low-voltage sub-network. The coupling unit is designed to selectively connect the battery units to the low-voltage sub-network. The disclosure further relates to a method for operating an electrical system, to a motor vehicle, and to a battery management system and a computer program which are designed to carry out the method.
