Abstract
A special silicon diode is disclosed which is shunted across each cell in a series connected string of battery cells. In response to a cell failure which causes a cell to open circuit, all battery current is routed through the diode looping element. This current causes a permanent state change of the looping element thereby causing the looping element to become a permanent short circuit. Thus, the failed cell is effectively removed from the circuit.
