摘要： A method for estimating the insulation resistance between a terminal of a battery (Batt) and an electrical earth, comprising: -connection of a measuring circuit (CM) to one terminal of the battery (Batt), said measuring circuit comprising a resistance (R) of known value and a capacitance (CE); and -application (1) of a known input signal having an input voltage (Ue). The method further comprises: -measurement (2) of an output voltage between the earth and a point (P) located between the resistance (R) of known value and the capacitance (CE); -determination (3) of a complex impedance of a dipole consisting of the capacitance (CE) and the insulation resistance (Risol) or determination of the parameters of a differential equation; and -determination (4) of the insulation resistance (Risol) from the parameters of the differential equation or said complex impedance.

摘要： The invention relates to a method and a device for equilibrating an accumulator battery. According to the method there is provided a battery comprising accumulators connected together in series and a charging current for charging said accumulators, said accumulators exhibiting a maximum charge state, and said accumulators are charged during a charging step so as to increase the charge of said accumulators up to their maximum charge state. Said charging step comprises the following substeps in order: a) said accumulators are fed in series with said charge current at said charging value until one of said accumulators of said battery reaches said maximum charge state; b) meanwhile said one of said accumulators is coupled to the terminals of a corresponding resistor, while the charge current is simultaneously reduced; and, c) return to substep a).
