Patent attributes
Embodiments are directed towards modular power plants that provide power to operate machines. A power plant is a combustion-electric hybrid power plant that includes at least one or more engines, one or more generators, and one or more battery arrays. The battery arrays include one or more modular batteries. Rather than the engine directly providing power to the machine, the engine and generators charge the batteries. The batteries provide the power required to operate the machine. A user may vary the maximum power output of the power plant by varying the number and/or type of modular batteries included in the one or more battery arrays. The specific configuration of the batteries may be based on the power requirements of the machine's expected usage or operation. The power plant is configured to a specific machine application by installing and/or removing batteries from the battery arrays based on the machine's power requirements.
