Abstract
The method for charging an electrochemical nickel-based battery having a predetermined nominal capacity, including at least one measurement of the voltage of the battery and one measurement of the temperature representative of the battery. The battery is connected to an intermittent source of energy. The charging of the battery is stopped when the voltage measured at the terminals of the battery reaches a voltage threshold, depending on the measured temperature and representative of a capacity charged in the battery corresponding to a charging efficiency equal to or higher than 90% of the maximum charging efficiency.
