Abstract
System including a switch control module that is configured to control operation of a first contactor and a second contactor in a vehicle system. The first and second contactors are configured to selectively connect front-end and direct-current (DC) buses, respectively, to an energy storage system of the vehicle system. The front-end bus is configured to receive electrical power from an external power source and provide the electrical power to a converter device. The converter device is configured to supply DC power to the DC bus. The switch control module is configured to close the second contactor when the vehicle system is operably coupled to the external power source so that the energy storage system is charged by the DC power. The switch control module is configured to close one of the first contactor or the second contactor when the vehicle system is operably decoupled to the external power source.
