Abstract:
1. A vehicle comprising: a high-voltage (HV) energy storage system (ESS); an HV power bus that is electrically connected to the ESS; a low-voltage (LV) power bus; a DC-DC power converter that is electrically connected to the LV power bus and to the HV power bus, and that has an HV bus connector and a pair of low voltage (LV) bus connectors; a vehicle module that is electrically connected to each of two sets of LV bus connectors; and a controller having a power flow control algorithm adapted for controlling an operation of the DC-DC power converter; wherein the controller selectively powers the vehicle module via one of the pair of LV bus connectors during a predetermined transient LV condition to ensure a threshold supply of LV power to the vehicle module, and via the LV power bus when the predetermined transient LV condition is no longer present.
