Brief description of a set of quadruplets of values relating to the points of operation of an accumulator subject-matter, the determination of a state of energy from the data from the process of treatment, the recording carrier, computer program.

摘要

Method for determining the state of energy of an electrochemical accumulator, characterized in that it comprises the following steps: using a predetermined set of quadruplets of values relating to operating points of the electrochemical accumulator, reading (E101) a first state of energy SOE1 from a memory, measuring (E102) a temperature (T1), and a power (P1), representing the current operation of the accumulator, determining (E103), on the basis of the predetermined set of quadruplets, a slope of the remaining energy En in the accumulator as a function of the state of energy SOE of the accumulator, at a point representing the first state of energy SOE1, as a function of the measured temperature and measured power (T1, P1), determining (E104) a second state of energy SOE2 as a function of the determined slope, notably  En  SOE   or    SOE  En , of the first state of energy SOE1, and an energy quantity (P·dt).
