METHOD AND SYSTEM FOR ESTIMATING THE INSULATION RESISTANCE BETWEEN A BATTERY AND AN ELECTRICAL EARTH |
摘要 |
<p>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.</p> |
