The invention provides an onboard ac generator for power-to-the-box in vehicles with a combustion engine. An AC inverter in a vehicle operates using a 24 V input when a vehicle powertrain is in a parked/idling state. A first 12 V battery is connected with a first bus segment. A second 12 V battery is connected with a second bus segment. A switch module selectably interconnects the first and secondbus segments. In a nominal 12 V state, the batteries are connected in parallel from the bus segments to ground. In a dual voltage state, the batteries are connected in series so the first bus segmentis at 12 V and the second bus segment is at 24 V. A first alternator driven by the powertrain provides a regulated voltage to the second bus segment, wherein the regulated voltage corresponds to 12 Vwhen the switch module is in the nominal state and corresponds to 24 V when the switch module is in the dual voltage state.

    本公开提供了“在具有燃烧发动机的车辆中用于向箱供电的车载AC发电机”。当车辆动力传动系统处于驻车/怠速状态时,车辆中的AC逆变器使用24V输入进行操作。第一12V电池与第一总线段连接。第二12V电池与第二总线段连接。开关模块将所述第一总线段和所述第二总线段可选择地互连。在标称12V状态下,所述电池从所述总线段并联连接。在双电压状态下,所述电池串联连接,因此所述第一总线段为12V并且所述第二总线段为24V。由所述动力传动系统驱动的第一交流发电机向所述第二总线段提供经调节的电压,其中所述经调节的电压在所述开关模块处于所述标称状态时对应于12V并且在所述开关模块处于所述双电压状态时对应于24V。
