Abstract: Embodiments disclosed herein relate to a battery energy storage system (BESS) that can be used to store energy that is produced by conventional sources (e.g., coal, gas, nuclear) as well as renewable sources (e.g., wind, solar), and provide the stored energy on-demand.

Abstract: The disclosed systems and methods are directed to a battery assisted charging station. A battery system comprising plurality of batteries and a battery management system software controlling the operations of the battery system, function together with a vehicle charging system that charges electric vehicles using one or both of stored power provided by a battery system, and power provided by a utility power grid. The battery system uses the power grid to charge the batteries therein.

Abstract: Embodiments disclosed herein relate to a battery pack that may be used in an battery energy storage system. In an embodiment, the battery pack may include an integrated battery management system (BMS) having isolated, distributed, daisy-chained battery module controllers. The daisy-chained battery module controllers may be coupled to a battery pack controller, which may charge and/or discharge the battery pack using the battery modules controllers and a balancing charger.

Abstract: Systems and methods are disclosed for detecting a battery pack having an operating issue or defect. In an embodiment, a balancing charger may be configured to charge a battery pack. An amount of time that the balancing charger is operating may be recorded. The recorded time may then be compared to a threshold time that indicates a determined variance from an expected operating time. If the recorded time exceeds the threshold time, the battery pack may be determined to have an operating issue or defect. In an embodiment, the threshold time may be adjusted based on an average battery cell or battery module temperature of the battery pack. In various embodiments, an alert may also be issued in response to determining that the battery pack has an operating issue or defect and operation of the battery pack may be halted to prevent any potential adverse effects.

Abstract: Systems and methods are disclosed for a warranty' tracker embedded in a battery pack. In an embodiment, the warranty tracker may include a memory device and a warranty controller. The warranty controller may receive an electric current measurement indicating a rate of charge or discharge of the battery pack from a device that is external to the battery pack. A warranty value may then be calculated using the received electric current measurement and added to a stored cumulative warranty value. The memory device may store the cumulative warranty value, which may be used to evaluate warranty conditions. In various embodiments, the warranty tracker may also include a temperature sensor and/or a voltage sensor. The warranty controller may then use received temperature and/or voltage measurements in the calculation of the warranty value. In an embodiment, the stored cumulative warranty value may be used to determine expiration of a warranty.

Abstract: An electrical energy storage unit and control system, and applications thereof. In an embodiment, the electrical energy storage unit (which may also be referred to as a battery energy storage system (“BESS”)) includes a battery system controller and battery packs. Each battery pack has battery cells, a battery pack controller that monitors the cells, a battery pack cell balancer that adjusts the amount of energy stored in the cells, and a battery pack charger. The battery pack controller operates the battery pack cell balancer and the battery pack charger to control the state-of-charge of the cells. In an embodiment, the cells are lithium ion battery cells.
