Abstract
An energy delivery system includes at least one string of two or more energy delivery modules electrically coupled in series. Each energy delivery module includes one or more energy delivery devices for storing and delivering electrical current, and a module monitor for monitoring and controlling each of the energy delivery devices. Each string of energy delivery modules includes a string communication path accessible to each of the energy delivery modules, wherein the module monitor of each energy delivery module is operable to communicate information associated with its energy delivery module through the string communication path. Each string also includes a string manager device for communicating with each module monitor in the string, through the string communication path. The energy delivery system also includes a system controller for communicating with each string manager device through a system communication path.
