Abstract
A method for starting a hybrid vehicle when the vehicle is already connected to an external power source. In some hybrid vehicles, it can be undesirable for an external power source (e.g., an AC power outlet) and an internal power source (e.g., an internal combustion engine/generator) to simultaneously provide the vehicle with electrical energy. There are a variety of reasons why this may be true. For instance, some hybrid vehicles may have difficulty accurately estimating the state-of-charge (SOC) of the vehicle battery when both external and internal power sources are simultaneously providing electrical energy to the vehicle's high voltage bus. The method described herein can arbitrate or otherwise determine which power source is preferable for the circumstances and then activate or enable that power source accordingly.
