    摘要： An apparatus for storing energy includes a plurality of energy storage cells, a switching circuit configured to control a transient voltage support to a battery provided by the plurality of energy storage cells, a charging circuit configured to charge the plurality of energy storage cells, and a processing system. The processing system is configured to control the charging circuit to charge the plurality of energy storage cells, and control the switching circuit to control the transient voltage support of the plurality of energy storage cells to the battery. The switching circuit and the charging circuit provide parallel paths between the plurality of energy storage cells and the battery terminal.

    摘要： Disclosed are systems and methods for improved cell-balancing circuits, back-up failure detection circuits and alarm extension for cells and modules of an energy storage system. One aspect of the invention comprises an energy storage device cell balancing apparatus. The apparatus comprises a first and a second dissipative component connected in series. The first dissipative component and the second dissipative component are coupled to an energy storage cell. The second dissipative component monitors a voltage of the energy storage cell and, if the voltage is at or above a reference voltage, the second dissipative component conducts a discharging current through the first and second dissipative components. The first dissipative component maintains a voltage drop across the first dissipative component that is proportional to the voltage of the energy storage cell. The second dissipative component maintains a constant voltage drop across the second dissipative component when conducting the discharging current.
