  • State of health of a battery
    Patent number: 11874333
    Abstract: A method of constructing a chart of correlations between a rapid discharge and a slow discharge in order to measure the wear of at least one electrochemical cell, including a measurement phase that includes a training sequence followed by a characterization sequence, and an aging phase. Each of the sequences includes charging-relaxing-discharging-relaxing under controlled conditions and is repeated with different conditions. The time of each discharge is measured. The aging phase includes an alternation of charges and discharges with no intermediate relaxation and is implemented before each repetition of the measurement phase, such that a real capacity is obtained for a plurality of pairs of imposed parameters.
