Abstract
A vehicle includes a high-voltage (HV) energy storage system (ESS), an HV power bus, a DC-DC power converter electrically connected to the HV power bus, an HV bus connector, a low voltage (LV) battery power bus, and a pair of LV bus connectors. The vehicle includes a vehicle module electrically connected to the HV and LV bus connectors, an LV power bus electrically connected to the DC-DC power converter and to the module, and a controller. The controller has an algorithm that controls the converter to power the module via one of the LV bus connectors during a transient LV condition. The converter and a method of controlling the same are also provided, with the method including determining the LV condition, powering the vehicle module via one of the LV bus connectors during the transient LV condition, and powering the module via the other LV connector otherwise.
