BATTERY SYSTEMS OPERABLE IN A BACKUP MODE AND RELATED METHODS

摘要

The present disclosure pertains to various embodiments of battery systems and related methods that may operate in a preconditioning mode based upon a predicted disturbance of service of an electrical utility. Such systems may include a battery configured to store electrical energy. A communication module may be configured to receive an indication of a predicted disturbance of an electrical utility. A battery management system may operate the battery system in a normal mode to maintain a state of charge (SOC) of the battery system within a normal mode SOC range. Upon receipt of an indication of the predicted disturbance from the communication module, the battery system may be transitioned to a preconditioning mode. The state of charge may be maintained within a preconditioning mode SOC range that exceeds the normal SOC range. The battery system may provide electrical energy during an actual disturbance affecting the electrical utility.

主权项

1. A battery system configured to operate in a preconditioning mode based upon a predicted disturbance of service of an electrical utility, comprising:
a battery system configured to store electrical energy; a communication module configured to receive an indication of a predicted disturbance of an electrical utility; a battery management system in communication with the battery system and the communication module, the battery management system configured to:
operate the battery system in a normal mode to maintain a state of charge (SOC) of the battery system within a normal mode SOC range;receive the indication of the predicted disturbance from the communication module;transition the battery system to a preconditioning mode upon receipt of the indication of the predicted disturbance and maintain the state of charge of the battery system within a preconditioning mode SOC range, the preconditioning mode SOC range exceeding the normal SOC range; andaccumulate electrical energy in the battery in the preconditioning mode up to a charge capacity cutoff threshold.
