Abstract: A power charging assembly (18) and methods are provided to provide a pre-charge low-current state, a steady-state, high-current charging state, and an unconnect state for an electrical load (16) of an electrical propulsion system in a hybrid electrical vehicle. The power charging assembly (18) includes a positive contactor device (26), a negative contactor device (28), and a non-contactor device (29) means. The rate at which that electrical load (16) is pre-charged may be effectively controlled by using a pulse-width modulated signal received by the non-contactor device means (29). A current-only carrying positive (26) or negative contactor (28) may be configured with the non-contactor (29) device means to further prevent electrical arcing of the contacts of the positive (26) and the negative (28) contactor during power charging assembly (18) operation.

Abstract: A power charging assembly and methods are provided to provide a pre-charge low-current state, a steady-state, high-current charging state, and an unconnect state for an electrical load of an electrical propulsion system in a hybrid electrical vehicle (HEV). The power charging assembly includes a positive contactor device, a negative contactor device, and a non-contactor device means. The rate at which that electrical load is pre-charged may be effectively controlled by using a pulse-width modulated (PWM) signal received by the non-contactor device means. A current-only carrying positive or negative contactor may be configured with the non-contactor device means to further prevent electrical arcing of the contacts of the positive and the negative contactor during power charging assembly operation.

Abstract translation: 提供了一种充电组件和方法，以提供用于混合动力电动车辆（HEV）中电力推进系统的电负载的预充电低电流状态，稳态，大电流充电状态和非连接状态 ）。 充电组件包括正接触器装置，负接触器装置和非接触器装置装置。 可以通过使用由非接触器装置装置接收的脉冲宽度调制（PWM）信号来有效地控制该电负载预充电的速率。 可以使用非接触器装置来构造仅电流承载正或负接触器，以在充电组装操作期间进一步防止正负接触器的触点的电弧。
