Abstract:
A method (200) of balancing ultracapacitor cells (102) is provided. The method may measure individual ultracapacitor cell voltages, select a balancing setpoint voltage, compare an actual voltage variation within each ultracapacitor cell (102) with a voltage variation threshold, and enable a balancing element (104) associated with the ultracapacitor cell (102) if the actual voltage variation exceeds the voltage variation threshold.
