Abstract: A multi-cell rechargeable energy storage system has battery cells disposed in an enclosure, and arranged in cell modules. Collectors are arranged to electrically connect the battery cells arranged in the cell modules. An electric power bus is arranged in a spine, and terminates at positive and negative terminals. First busbars, a second busbar, and end collectors electrically connect the cell modules in series between the positive terminal and the second terminal. Cell monitoring controllers are arranged to monitor the cell modules. A potting compound is arranged to encapsulate only an upper portion of the battery cells. A thermal management system including first and second fluidic manifolds are fluidly coupled to longitudinal heat exchange plates to thermally couple to the battery cells.
