Abstract
The present disclosure relates to an on-board electrical network for a motor vehicle. The motor vehicle comprises a battery cell unit configured as a so-called SmartCell. The on-board electrical network also comprises a controller for operating the battery cell unit. In order to be able to be supplied with electric energy, the controller comprises a supply connection for supplying a supply voltage. The supply voltage is usually supplied by an energy supply device of the on-board electrical network, which is coupled to the controller via a first connection line. In order to allow for a redundant energy supply for the controller, a second connection line is provided in addition to the first connection line, via which a battery cell of the respective battery cell unit is coupled to the supply connection. The supply voltage can thus be supplied either via the first connection line or via the second connection line on the basis of an operating state of the energy supply device.
