The invention relates to an on-board electrical system (20) for a motor vehicle (10), comprising: a high-voltage network (22) comprising a high-voltage energy store (24) for supplying voltage to one or more high-voltage consumers; a main converter (32) for converting a high voltage present in the high voltage network (22) into a predetermined low voltage present in the low voltage network (28) for voltage supply of one or more low voltage consumers; a battery management system (26) and a bypass converter assembly (36). The bypass converter arrangement (36) is designed to introduce a determined maximum permissible energy amount from the high-voltage network (22) into the low-voltage network (28) during a parking phase of the motor vehicle (10). The invention further relates to a method for controlling such an on-board electrical system (20) and to a motor vehicle having such an on-board electrical system (20).

    本发明涉及一种用于机动车(10)的车载电网系统(20),所述车载电网系统具有:包括高电压蓄能器(24)的高压电压网络(22)以用于一个或多个高电压用电器的电压供应;主变换器(32),其用于将在高压电压网络(22)中存在的高压电压转换为在低压电压网络(28)中存在的预定的低压电压,以用于一个或多个低电压用电器的电压供应;电池管理系统(26)和旁路变换器组件(36)。旁路变换器组件(36)设置用于在机动车(10)的停放阶段期间将确定的最大允许能量额从高压电压网络(22)引入到低压电压网络(28)中。此外,本发明涉及一种用于控制这样的车载电网系统(20)的方法以及一种具有这样的车载电网系统(20)的机动车。
