Abstract
Systems and methods for evaluating an engine associated with a hybrid power system, including initiating a load step on the engine using a battery of the hybrid power system, measuring a plurality of parameters associated with a response of the engine to the load step using a plurality of sensors, comparing the measured parameters associated with the response of the engine to baseline performance data associated with the engine, and calculating an engine performance score for the engine based on the comparison of the measured parameters to the baseline performance data.
