Product Announcement from TPL, Inc.
TPL, Inc. is an Albuquerque, NM small business focused on materials science-based technology development and manufacturing with expertise in energetic materials, dielectrics and micropower systems. The Micropower Technologies Division of TPL Inc. was formed in 2006 to concentrate efforts on commercialization of EnerPak products to meet the need for reliable, long-lived power in the growing wireless sensor market.
TPL's EnerPak provides an innovative power management solution to accommodate the low, variable and intermittent nature of energy harvesting sources. The patent pending design combines ultra-low power circuitry, a microprocessor-controlled charge management system that dynamically responds to fluctuating input energy levels and can continue to charge the storage system even when the harvested voltage is below battery voltage, and an optimized energy storage system.
Designed around the Texas Instruments MSP430 ultra-low power microcontroller, the EnerPak can consume as little as 5-8µA, enabling efficient use of the harvested energy for the application. The system also includes a lithium-polymer battery to provide back-up power in the event of a failure of the ambient energy while low impedance supercapacitors enable efficient delivery of high power burst loads. Proprietary charging methods enable efficient battery charging even when the harvester power is low.
Nominally designed for use in low-power wireless sensor applications (e.g. ZigBee, HART, SP100), etc.,) the EnerPak can be customized for any user-specified profile. It is also compatible with multiple different energy harvester devices (e.g. thermoelectric, photovoltaic, vibration) as the application demands. Currently two systems are available: the power management electronics and energy storage system that can be used with a harvester of the user's choice (EP-1), or a module with an integrated 1"x 2" photovoltaic (PV) array (SC-1). With a total volume comparable to that of a standard D cell, the EnerPak is available either as an enclosed system, or as a stand alone board. TPL's EnerPak is now available for beta-testing for interested customers.
