用于使车载电网运行的方法
摘要：
本发明涉及一种用于使机动车的车载电网（1）运行的方法，其中所述车载电网（1）具有：低压子网（21），其具有至少一个低压耗电器（29）和起动器（26）；和高压子网（20），其具有至少一个高压耗电器（25）和发电机（23），其中所述高压子网（20）通过耦合单元（33）与低压子网（21）相连，所述耦合单元（33）被设立为从高压子网（20）汲取能量并且将该能量输送给低压子网（21），其中所述高压子网（20）具有如下电池组（40），所述电池组（40）被设立为产生高压并且将该高压发出给高压子网（20），而且所述电池组（40）具有至少两个带有被导向耦合单元（33）的线路段（80‑11、80‑12、…、80‑n2）的电池组单元（41‑1、41‑2、…41‑n）。在此，所述耦合单元（33）被设立为选择性地将所述电池组单元（41‑1、41‑2、…41‑n）接入给低压子网（21）。本发明也涉及一种具有内燃机和这样的车载电网（1）的机动车。
摘要（英）：

The invention relates to a method for operating an on-board electrical system (1) for a motor vehicle, wherein the on-board electrical system (1) has a low-voltage electrical subsystem (21) with at least one low-voltage load (29) and a starter (26), and has a high-voltage electrical subsystem (20) having at least one high-voltage load (25) and one electrical generator (23), wherein the high-voltage electrical subsystem (20) is connected to the low-voltage electrical subsystem (21) by means of a coupling unit (33) which is designed to draw energy from the high-voltage electrical subsystem (20) and to supply energy to the low-voltage electrical subsystem (21), wherein the high-voltage electrical subsystem (20) has a battery (40) which is designed to generate the high voltage and output said high voltage to the high-voltage electrical subsystem (20), and which has at least two battery units (41-1, 41-2, . . . , 41-n) with line sections (80-11, 80-12, . . . , 80-n2) which are routed to the coupling unit (33). In this case, the coupling unit (33) is designed to selectively connect the battery units (41-1, 41-2, . . . , 41-n) to the low-voltage electrical subsystem (21). The invention also relates to a motor vehicle comprising an internal combustion engine and an on-board electrical system (1) of this kind.
