A method of charging a battery of electric accumulators from the electric power supplied by an electric generator, wherein the battery is charged to a first maximum state of charge in a first operating mode and to a second maximum state of charge, lower than the first maximum state of charge, in a second operating mode, the method including switching from the second operating mode to the first operating mode when a criterion using the battery temperature or the ratio of a first quantity representative of the available power which may be supplied by the electric generator to a second quantity representative of the power consumed from the battery is fulfilled.

Battery charge method and device

Method for managing a battery comprising several accumulators that can be linked in series or in parallel, comprising a charging or discharging phase during which the accumulators are disposed in series, characterized in that it thereafter comprises a balancing phase comprising the placing of the accumulators in parallel, during which an electrical quantity Grepresenting the balancing of the accumulator that has attained the maximum voltage during the charging phase or minimum voltage during the discharging phase is measured or estimated, and during which an electrical quantity Grepresenting the balancing of another accumulator i of the battery is also measured or estimated, and in that the state of health SOHof this other accumulator i is computed on the basis of the two electrical quantities Gand Gand on the basis of the knowledge of the performance of the accumulator i at the start of life.

Method for battery management and diagnosis
