The invention relates to an on-board electrical system (B) for a motor vehicle. Here, the motor vehicle comprises at least one battery cell unit (10), which is designed as a so-called Smart Cell. In order to operate the battery cell unit (10), the on-board electrical system (B) further comprises a control device (20). In order to be able to supply electrical energy, the control device (20) comprises a supply connection (V) for supplying a supply voltage (UV). Generally, the supply voltage (UV) is supplied by means of an energy supply device (30) of the on-board electrical system (B), which can be coupled to the control device (20) via a first connection line (A1). In order to achieve a redundant power supply of the control device (20), a second connection line (A2) is provided in addition to the first connection line (A1), via which the battery cells (11) of the respective battery cell unit (10) can be coupled to the power supply interface (V). Thus, the supply voltage (UV) can be supplied via the first connection line (AL) or via the second connection line (A2) as a function of the operating state of the energy supply device (30).

    本发明涉及一种用于机动车的车载电网(B)。在此,机动车包括至少一个电池电芯单元(10),其构造成所谓的SmartCell。为了运行电池电芯单元(10),车载电网(B)此外包括控制装置(20)。为了能够供给电能,控制装置(20)包括用于输送供电电压(UV)的供电接口(V)。通常,在此借助车载电网(B)的能量供给装置(30)输送供电电压(UV),能量供给装置可通过第一联接线路(A1)与控制装置(20)耦联。为了实现控制装置(20)的冗余的能量供给,除了第一联接线路(A1)以外还设置第二联接线路(A2),相应的电池电芯单元(10)的电池电芯(11)可通过第二联接线路与供电接口(V)耦联。因此,根据能量供给装置(30)的运行状态可通过第一联接线路(AL)或通过第二联接线路(A2)输送供电电压(UV)。
