Abstract: A system and method for the thermal management of a battery-based energy storage is described. One embodiment includes a thermal management system for a battery-based energy storage system, the thermal management system comprising a residual heat source, such as a geothermal heat source, and a battery-based energy storage system thermally connected to the residual heat source The thermal connection between the energy storage system and the residual heat source may be direct (i.e., the energy storage system may be adjacent to, partially located within, or fully located within the residual heat source) or indirect (e.g., the energy storage system and residual heat source may use a heat conduit to transfer heat). In embodiments using a heat conduit to transfer heat, the thermal management system may further comprise a control system for controlling the circulation of a fluid in the heat conduit in order to regulate the temperature of the energy storage system.

Abstract: A new method for measuring the temperature gradient of a well is claimed. This method uses multiple and parallel temperature sensors to calculate the well's temperature at each point in the well. This reduces noise found in electronic measurements in order to improve the well's temperature measurement and improve the calculation of the well's temperature gradient. The use of natural background gamma enhances the calculation of the well's temperature gradient and improves the detection of changing rock formations intersecting the well.

Abstract: The creation of a circuit board which contains electrical interconnections between the circuit board traces and electronic devices mounted on the circuit board where the circuit board assembly can be operated at temperatures of 600° C. or greater. This invention allows for solder connections to be formed using solder paste or high-temperature.

Abstract: Systems and methods for subterranean imaging and logging are herein disclosed. In one embodiment, a subterranean tool for logging and imaging a subterranean well is provided. The subterranean tool includes a tool body, at least one transducer arranged within the tool body and an acoustic window coupled to the transducer.

Abstract: A novel means for placing conductive metal traces on ceramic without adhesives, glues or any organic materials. Metal traces created by thermal spraying metal on to a prepared ceramic surface. The ceramic surface is prepared by creating recesses where the metal is to remain as circuit traces. Following thermal spray, the excess metal is removed from the surface leaving the metal electrically conductive traces in the ceramic recesses. This process improves metal to ceramic bond, reducing failures caused from thermal expansion differences between ceramic and metal traces and eliminates all organic adhesives.

Abstract: A system for maintaining battery temperatures for energy storage systems using heat created by power electronic device needed to interface the batteries to external power sources or loads is described. Waste heat is a product of internal resistance found in all electronic devices passing current. High-temperature electronics comprised of, silicon-on-insulator, silicon-on-sapphire, silicon-carbide, gallium-nitride or in conjunction with or combination of other wide bandgap semiconductors can used to monitor, charge or discharge the battery array. A thermal system where heat generated by power electronics is used to assist the thermal management of battery energy storage system increases overall system efficiency.
