Abstract
A method and apparatus for automatically monitoring and controlling various parameters of individual ultracapacitor cells in a series string of such cells. These parameters are monitored, and a replacement charge current is delivered to any cell which has lost charge due to discharge either external or internal to the cell. Also, the application of this method and apparatus to energy storage systems for an electrical power transmission grid.
