METHOD FOR DETERMINING AN OPERATING STATE OF ELECTRICAL POWER STORAGE MEANS CONSISTING OF AT LEAST ONE ULTRACAPACITOR |
摘要 |
<p>The invention relates to a method for determining the operating state of electrical power storage means consisting of at least one ultracapacitor. When charging said electrical power storage means, the invention involves: measuring the voltage in the terminals of said means and measuring the time interval ?t required for said means to be charged with an initial voltage "Uinit" at a final voltage set value "Ufinal" at a given constant current I; calculating the charge speed of said means in V/s; comparing said charge speed with at least one given speed threshold value; when the measured charge speed is less than said threshold value, determining that the means have a so-called "good health" operating state; and when the charge is greater than that same threshold value, determining that the means have a so-called "end of life" operating state. The invention can be used in vehicles provided with an "A & R" system.</p> |
