Abstract
The invention relates to a device for measuring battery voltage including an accumulator (Ai), characterized in that said measuring device comprises: an alternating current generator (II), at least one first diode (D1i) and at least one second diode (D2i) arranged in series such that said first diode (D1i) is connected to the positive pole (+) of said accumulator (Ai) by means of the cathode thereof and to the cathode of said second diode (D2i) by means of the anode thereof and such that said second diode (D2i) is connected to the negative pole (−) of said accumulator (Ai) by means of the anode thereof and to the anode of said first diode (D1i) by means of the cathode thereof, a reading capacitor (C1) connected to the central point (N) between said first (D1i) and second (D2i) diodes and to a means (3) for determining the voltage across the terminals of said accumulator (Ai) from the voltage variation at the central point (N).
