    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.

    Abstract: The present disclosure is directed to a system and method for controlling an energy storage device by more accurately detecting an end-of-discharge voltage of the energy storage device. More specifically, in one embodiment, the method includes determining an end-of-discharge voltage threshold for the energy storage device. Another step includes filtering the end-of-discharge voltage threshold via a filter. The method also includes adjusting a time constant of the filter based on at least one voltage-current condition. Still a further step includes comparing the filtered end-of-discharge voltage threshold and a terminal voltage of the energy storage device. Based on the comparison, the method includes determining a change of state of the energy storage device. Thus, the energy storage device can be controlled based on the change of state.

    Abstract: The present disclosure is directed to a system and method for reducing current variability between a plurality of energy storage devices, e.g. battery modules. In one embodiment, the method includes determining a resistance of at least two of the plurality of energy storage devices. Another step includes modifying an operating temperature of one or more of the plurality of energy storage devices when the resistance of one or more of the energy storage devices is outside of a predetermined tolerance range for the energy storage devices. Thus, the step of modifying the operating temperature of one or more of the plurality of energy storage devices causes the plurality of energy storage devices to operate within the predetermined tolerance range.

    Abstract: The present disclosure is directed to a system and method for controlling an energy storage system. The energy storage system includes a plurality of battery strings connected in parallel with the battery strings having a plurality of batteries connected in series. The method includes determining, via a controller, one or more operating parameters of the energy storage system. The method also includes determining, via the controller, a maximum current rating of one or more of the battery strings. Another step includes estimating, via the controller, a voltage range for the one or more battery strings as a function of the one or more operating parameters and the maximum current rating. The method also includes dynamically controlling the one or more battery strings based on the voltage range so as to prevent over-current recharge or discharge of the parallel battery strings.

    Abstract: Systems and methods of controlling a dispatch operation of an energy storage system are provided. In particular, a degradation value of a present dispatch state of an energy storage system can be determined. The present dispatch state can specify one or more energy storage units presently coupled to the system. The degradation value can be determined based at least in part on one or more operating parameters, such as temperature, open circuit voltage, charge or discharge current, and/or contactor life. The degradation value can then be compared against one or more degradation values associated with one or more candidate dispatch states. A dispatch state can then be selected based on the comparison. One or more energy storage units can be selectively coupled to the energy storage system based at least in part on the selected dispatch state.
