Electro Standards Laboratories, Cranston, RI, is advancing the science of high-density energy storage with high pulsed power capability for remote sensor systems. This technology is directly related to sensor systems which often require low level continuous monitoring followed by high power bursts of energy to transmit their data. This technology involves advanced ultra-capacitors and hybrid battery/ultra-capacitor modules.
Projects include powering sensor systems in remote energy harvesting buoys. These power systems utilize embedded linear generators to accumulate ocean wave heave energy. This energy can be used to power sensors for long periods of time since the energy is being replenished from the environment.
Electro Standards Laboratories is also applying its expertise to the science of harvesting energy from undersea currents utilizing optimized underwater generators. Smart algorithms tune the controls to maximize energy harvesting.
Electro Standards Laboratories has developed advanced electric motor control algorithms. Their successes include the development of high performance servo control of AC machines including adaptive control for changing environments and parameter estimation for motor diagnostics and prognostics. An important achievement is the design of fault resilient controls for systems in demanding environments that must continue to operate in the event of sensor failures. Sensorless control of AC motors has been accomplished with the development and implementation of mechanically sensorless control to allow high-fidelity control of AC machines in the absence of position sensors. The company has designed power electronics systems to provide power management for hybrid electric and battery management.
This high-density energy storage with high pulsed power capability technology is now readied for further development for commercial applications. Applications could include emergency beacons for all commercial and recreational watercraft and for offshore rig-monitoring buoys in the oil and gas industries. Longer term development would target scaling up the technology to provide an inexhaustible source of renewable electrical energy for powering larger systems. Parties interested in this technology for their specific applications are invited to contact Electro Standards Laboratories. Dr. Raymond B. Sepe, Jr., is Vice President of the R&D Engineering Services Group and a principal in the company. Dr. Sepe can be reached at email@example.com or 401-943-1164.
