SYSTEM AND METHOD FOR DETERMINING HEALTH OF AN ENGINE-GENERATOR SET
First Claim
1. A method for determining health of an engine-generator set of a hybrid power system comprising at least one battery power source, the method comprising:
- sending, by a battery management system, a start-up command to the engine-generator set;
after sending the start-up command, determining at least one start-up condition of the hybrid power system;
generating a start-up condition trend based on a plurality of the start-up conditions of the hybrid power system over multiple start-ups; and
,determining the health of the engine-generator set based on a comparison of the start-up condition trend and a threshold start-up condition for the engine-generator set.

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.
