<p>The present invention relates to a hybrid electrical power source comprising two or more electrical energy sources that supply energy to a connected load, such as a combination of fuel cell and battery. The present invention comprises first and second electrical energy sources configured to supply current to an output, and a controller configured to receive a signal indicative of the current being drawn at the output, to compare the output current with a reference current level, and to regulate the voltage provided by the one of the first or second electrical energy sources such that: when the output current is lower than the reference current level, the first energy source supplies current equal to the output current; and, when the output current exceeds the reference current level, the first energy source supplies current equal to the reference current level and the second energy source supplies the remaining current required by the load.</p> |
