The invention relates to a vehicle power grid and a method for operating the vehicle power grid. A vehicle power grid for a motor vehicle is provided with at least one low voltage customer, at least one high voltage customer, a starter, and a high voltage sub power grid for a generator and a battery pack. The battery pack is used to generate high voltage and output the high voltage to the high voltage sub power grid; the high voltage sub power grid is connected with the low voltage power grid through a coupling unit; the coupling unit is used to extract energy from the high voltage sub power grid and delivery to the low voltage sub power grid, and is also set up for the low voltage power sub grid to extract energy and deliver the energy to the high voltage sub power grid; the battery pack is provided with at least two battery units with voltage branch points which are guided to the coupling unit; and the coupling unit is set up to selectively to access the battery units to the low voltage sub power grid and the low voltage sub power grid.
