Abstract
A rechargeable electrochemical cell charger is provided for charging electrochemical cells at high current rates. The charger provides a sufficient force between the charge contacts and the cell terminals to remove nonconductive contaminants when the cell is inserted into the charger, thereby increasing the conductivity at the point of contact. The charger can include an air moving system for the dissipation of heat from the electrochemical cell during charging, and a heat sensor to determine the cell temperature during charging.
