A system 10 for charging a high voltage bus 12 within a vehicle 14 including one or more sources of electrical power 16 which provide electrical power to the vehicle 14. System 10 includes a controller 18, a pre-charge contactor 20 and pre-charge resistor 22, a main contactor 24, and a bus voltage sensor 26. Pre-charge contactor 20 and main contactor 24 are each respectively and communicatively coupled to controller 18 by use of electrical buses 28, 30, and sensor 26 is communicatively coupled to controller 18 by use of electrical bus 32. Controller 18 calculates the voltage and change in voltage over time of bus 12 and uses these values within a state machine strategy 50 to close contactors 20, 24, thereby charging high voltage bus 12. |
