Method and apparatus for in-situ characterization of energy storage and energy conversion devices

Patent Christophersen, Jon P [Idaho Falls, ID]; Motloch, Chester G [Idaho Falls, ID]; Morrison, John L [Butte, MT]; ...

Disclosed are methods and apparatuses for determining an impedance of an energy-output device using a random noise stimulus applied to the energy-output device. A random noise signal is generated and converted to a random noise stimulus as a current source correlated to the random noise signal. A bias-reduced response of the energy-output device to the random noise stimulus is generated by comparing a voltage at the energy-output device terminal to an average voltage signal. The random noise stimulus and bias-reduced response may be periodically sampled to generate a time-varying current stimulus and a time-varying voltage response, which may be correlatedmore »« less

Patent Rouillard, Jean [Saint-Luc, CA]; Comte, Christophe [Montreal, CA]; Daigle, Dominik [St-Hyacinthe, CA]

A bypass apparatus and method for series connected energy storage devices. Each of the energy storage devices coupled to a common series connection has an associated bypass unit connected thereto in parallel. A current bypass unit includes a sensor which is coupled in parallel with an associated energy storage device or cell and senses an energy parameter indicative of an energy state of the cell, such as cell voltage. A bypass switch is coupled in parallel with the energy storage cell and operable between a non-activated state and an activated state. The bypass switch, when in the non-activated state, ismore »« less
