Abstract

A battery management system includes one or more fiber optic sensors configured to be disposed within an electrochemical battery. Each fiber optic sensor is capable of receiving input light and providing output light that varies based on the input light and an amount of free or dissolved gas present within the battery. A detector detects the output light and generates an electrical detector signal in response to the output light. Battery management circuitry determines the state of the battery based at least in part on the detector signal.

Fiber optic position and/or shape sensing based on rayleigh scatter

Patent Froggatt, Mark E.; Duncan, Roger G.

A fiber optic position and/or shape sensing device includes an optical fiber with either two or more single core optical fibers or a multi-core optical fiber having two or more fiber cores. In either case, the fiber cores are spaced apart so that mode coupling between the fiber cores is reduced, and preferably, minimized. The optical fiber is physically associated with an object. Strain on at least a portion of the optical fiber where it is associated with the object is determined by an OFDR using one or more Rayleigh scatter patterns for that portion of the optical fiber.

Distributed sensing of electromagnetic components using optical fiber based methods

Patent Ohodnicki, Paul R.; McHenry, Michael E.; Leary, Alex M.; ...

An OFDR based fiber-optics sensor for distributed real-time temperature rise monitoring of a transformer in operation has been disclosed. The fiber-optic sensor provides an effective solution to monitoring the physical structures of the transformer core, as well as accurately detecting the non-uniform temperature distribution inside the transformer, and thus provides innovative feedback to the transformer design by minimizing the core losses. Additionally, the method may be responsive to the presence of magnetic and electric fields, as well as responsive to various chemical species. The method allows novel approaches to real-time asset monitoring of power transformers while operational.

Optical waveguide methods for detecting internal faults in operating batteries

Patent Saunders, James H.; Morrow, C. Alexander; Risser, Steven M.; ...

Light is transmitted from a light source through or from a separator of a battery cell and received by one or more light detectors. The light that is normally transmitted through the separator is scattered, absorbed, wavelength-shifted or otherwise distorted by an impending fault in the vicinity of or within the separator. The change in light due to the impending fault is measured by a detector and a signal from the detector is processed to identify the impending fault so that a warning can be generated indicative of the impending fault. In particular, the separator and a battery cell electrolytemore » « less
