<p>A method for charging a sealed, secondary electrochemical power source having with a water based electrolyte (20), a gas space (20) and the possibility of recombination in accordance with the oxygen cycle during pressure stabilization at a low controlled level. Charging takes place at a constant d.c. voltage whilst the pressure inside the gas space of the power source is reduced by evacuation. An arrangement for implementing the method consists essentially of a vacuum pump which is connected to the gas space of the power source via an evacuation line, and of a constant d.c. voltage source. The vacuum pump is so arranged as to come into operation when the power source is being charged.</p> |
