METHOD FOR MEASURING THE CHARGE STATE OF AN ACCUMULATOR AND DEVICE FOR IMPLEMENTING SUCH METHOD

摘要

The method consists in measuring the temporary voltage drop across the accumulator terminals upon an important current flow. The measuring device of such maximum voltage drop comprises a first maximum detector (43) feeding a voltmeter (42) and connected to the output terminal of a subtractor (44) of which the so-called reverser input is connected to the accumulator through a filter (45) and of which the so-called non-reverser input is connected to the accumulator through a second maximum detector (46). Application to the measurement of the charge state of an accumulator.
