Abstract
Method and system are provided that allow determining in a vehicle having two or more sources of electrical energy what corrective action needs to be undertaken in the event one of the energy sources, due to malfunctions and/or environmental conditions, is not able to carry through a cranking event. The system, by way of a bidirectional DC/DC converter, has the capability to transfer electrical energy in either direction between the energy sources. The system includes a controller configurable with computer-readable logic or intelligence that enables the controller to make a decision based on appropriate source parameters, e.g., temperature, to automatically determine when, where, and how much energy needs to be transferred. This decision will enhance the opportunity to successfully perform the next starting or cranking event.
