An exemplary electrical system is disclosed. The electrical system may include a rechargeable energy storage system (RESS) and a power inverter connected to the RESS. The power inverter may be configured to provide power to the traction motor. The electrical system may include a plurality of motor windings connected between a power inverter and a switch. The switch may be configured to transition between a closed state that causes current to flow from the off-board power supply through the plurality of motor windings to the RESS and an open state that prevents current from flowing between the off-board power supply and the plurality of motor windings.
公开了一种示例性电气系统。该电气系统可以包括可再充电能量存储系统(RESS)和连接到RESS的功率逆变器。功率逆变器可以被配置成向牵引电动机提供电力。该电气系统可以包括连接在功率逆变器和开关之间的多个电机绕组。开关可以被配置成在闭合状态和打开状态之间转换,闭合状态使得电流从非车载电源通过多个电机绕组流到RESS,打开状态阻止电流在非车载电源和多个电机绕组之间流动。
