| 摘要 |
<p>The invention relates to a method comprising the following steps consisting in: activating a measurement time window (Ws) upon detection of a discharge (Ib) of the battery that is above a threshold (Ith); collecting battery current and voltage measurement samples and, among said measurement samples, finding a voltage-current measurement pair (Ubmin, Ibmax) which, at the same measurement time (tm), corresponds to a minimum voltage value sample and a maximum current value sample; and calculating the internal resistance (Rb) from the measurement pair obtained and from another voltage-current pair (Ubr, Ibr) measured prior to the activation of the measurement window.</p> |
