  • Publication number: 20160061173
    Abstract: The present disclosure is directed to systems and methods for determining health of an engine-generator set of a hybrid power system having at least one battery power source. For example, in one embodiment, a battery management system sends a start-up command to the engine-generator set. After sending the command, at least one start-up condition (e.g. a start-up time lapse, a start-up voltage parameter of a starter battery of the engine-generator set, or a voltage of the battery power source before sending the start-up command) is determined for the hybrid power system. Next, a start-up condition trend is generated based on a plurality of the start-up conditions over multiple start-ups. Thus, the engine-generator set health can be determined based on a comparison of the start-up condition trend and a threshold start-up condition for the engine-generator set.
