Abstract
Physical measurement system at the heart of an electrochemical accumulator and associated method The present invention relates to a physical measurement system (10) at the heart of an accumulator (12) having two distinct power terminals (16, 18), comprising: - a capacitive sensor (20) inside said accumulator; - an assembly (22) of electrical elements external to said accumulator so as to form, with said capacitive sensor (20), a resonant circuit in a first predetermined frequency range; - a measurement module (26), external to said accumulator, configured to: - excite said resonant circuit, via a frequency sweep by driving a supply voltage over a second extended predetermined frequency range including said first range; - measure at least one resonant frequency resulting from said excitation; - obtain a value of an internal physical quantity of said accumulator from said at least one measured resonant frequency.Figure for the abbreviation: Figure 1.
