Assembly and method to charge an electrical load in an electric vehicle |
摘要 |
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. |
