Реферат: For a circuit for preventing overcharging of a battery cell, the overcharging protecting circuit having a voltage detector for monitoring the voltage across the battery cell, a polarity protection circuit for protecting the voltage detector from a reverse polarity connection of the battery cell to the voltage detector is disclosed. The polarity protection circuit comprises a semiconductor device coupled across voltage detection inputs of the voltage detector. The semiconductor device is adapted to shunt current across the voltage detection inputs of the voltage detector when the battery cell is connected in reverse polarity to the voltage detector.
