The present disclosure relates to a vehicle power distribution circuit and a vehicle power system, in particular to a vehicle power distribution circuit (14) connected between an energy store (2) and a power line (8) connected to a generator or a DC/DC converter (9). The circuit (14) has a charging line (7) connected between the energy store (2) and the power line (8) for charging the energy store (2) when a forward voltage is applied to the generator or the DC/DC converter (9). A protection switch (6) is provided in the charging line (7) and can be opened in response to a voltage drop on the power line (8) to prevent conduction of current through the protection switch (6). An ideal diode arrangement (13) is connected in parallel with the protection switch (6) in the charging line (7) for conducting a forward current from the generator or DC/DC converter (9) to the energy store (2). The ideal diode configuration (13) prevents conduction of a reverse current when a reverse voltage is applied.
本公开涉及车辆配电电路和车辆电力系统,尤其涉及一种连接在能量存储器(2)与连接到发电机或DC/DC转换器(9)的电力线(8)之间车辆配电电路(14)。该电路(14)具有连接在能量存储器(2)与电力线(8)之间的充电线(7),用于在发电机或DC/DC转换器(9)施加正向电压时对能量存储器(2)充电。保护开关(6)设置在充电线(7)中,并且能响应于电力线(8)上的电压下降而断开以防止通过保护开关(6)传导电流。理想二极管配置(13)与充电线(7)中的保护开关(6)并联,用于将正向电流从发电机或DC/DC转换器(9)传导到能量存储器(2)。理想二极管配置(13)防止在施加反向电压时传导反向电流。
