    摘要: Systems and methods for determining self discharge currents in an energy storage cell and detecting internal shorts are disclosed. A system includes a DC voltage source configured to provide a constant test voltage selected to be less than an open circuit voltage of an energy storage cell to the energy storage cell. The system also includes a current measuring device operably coupled between the DC voltage source and the energy storage cell, and control circuitry operably coupled to the current measuring device. A method includes applying the constant test voltage, and measuring the test current flowing between the DC voltage source and the energy storage cell until after the test current switches from a negative current to a positive current. The method also includes determining a self discharge current of the energy storage cell by analyzing the measured test current with computational models that capture physical processes tied to the test methods.

    摘要: In described examples of a method of evaluating at least one parameter of a first capacitor, the method couples at least three capacitors (C 1 , C 2 , C 3 ) in a capacitor network to a common node. First (200), the method applies a first voltage range to the capacitor network for causing a first voltage drop across the first capacitor, and it evaluates the at least one parameter in response to the first voltage range. Second (300), the method applies a second voltage range to the capacitor network for causing a second voltage drop across the first capacitor, the second voltage drop being greater than the first voltage drop, and it evaluates the at least one parameter in response to the second voltage range.

    摘要: Embodiments of the invention provide systems and methods for tracking the thermal age of a self-regulating heating cable. Over a time period, current and voltage data for a cable signal are collected, from which spectral information is extracted. The spectral information has a frequency component and an amplitude component. The cable signal is processed to extract a line frequency signature that includes the electrical system's line current frequency and at least some of its harmonics. A ratio of the amplitudes of at least two of the odd harmonics of the line current frequency is calculated. The ratio is compared to an aging curve indicating the thermal age of the cable as a function of the odd-harmonic ratios. The curve may be obtained in a laboratory setting or in the field by characterizing a cable with zero hours of use. The characterizing may include aging the cable to determine the curve.
