The invention relates to an on-board electrical system for a motor vehicle (1), comprising a control device (4), an energy store (3) and a plurality of components (5-9) which can be operated by means of the energy store (3), the on-board electrical system (2) being divided into at least two sub-electrical systems (10-14) and each sub-electrical system (10-14) comprising at least one of the components (5-9), the components (5-9) of different sub-networks (10-14) are each assigned to at least one different operating state of the motor vehicle (1), each of the sub-networks (10-14) can be separated from the energy store (3) by means of at least one switching device (15-19), and the control device (4) is designed to actuate the switching devices (15-19) as a function of operating state information describing at least one current operating state of the motor vehicle (1), the partial network (10-14) comprising the components (5-9) assigned to the current operating state is connected to the energy store (3), and the partial network (10-14) not comprising the components (5-9) assigned to the current operating state is separated from the energy store (3).

    一种用于机动车(1)的车载电网,其包括控制装置(4)、蓄能器(3)和多个能通过蓄能器(3)运行的部件(5‑9),车载电网(2)被划分为至少两个子电网(10‑14)并且子电网(10‑14)分别包括部件(5‑9)中的至少一个,不同子电网(10‑14)的部件(5‑9)分别被分配给机动车(1)的至少一个不同运行状态,子电网(10‑14)中的每个能通过至少一个开关装置(15‑19)与蓄能器(3)分离,控制装置(4)被设置用于,根据描述机动车(1)的至少一个当前运行状态的运行状态信息来操控开关装置(15‑19),使得包括被分配给当前运行状态的部件(5‑9)的子电网(10‑14)与蓄能器(3)连接,而使得不包括被分配给当前运行状态的部件(5‑9)的子电网(10‑14)与蓄能器(3)分离。
