Open circuit voltage checking for a battery system
Abstract:
Systems and methods for managing open circuit voltage checks of energy storage modules in an energy storage system. Embodiments of the present invention provide a controller of an energy storage system configured to schedule open circuit voltage checks for the energy storage modules, determine if conditions of an energy storage module, and of the overall energy storage system, are favorable for performing an open circuit voltage check, and defer an open circuit voltage check if at least one condition is not favorable. The controller is further configured to abandon an open circuit voltage check in progress if one or more conditions of the overall energy storage system changes in a manner that is unfavorable for continuing with the open circuit voltage check.
