Abstract
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.
