Electro Standards Laboratories Hybrid Power Management Unit (HPMU) Model 1041

Hybrid Unit allows Battery Life to be Extended Applicable to Portable Communications Devices Military Communications & Other Applications The Model 1041 Hybrid Power Management Unit combines the strength of a high-power capacitor and a high energy battery. A power management board integrates the two energy-storage devices and provides the user with a light-weight, high performance, and safe power source. This hybrid technology greatly benefits pulsed power load systems that are typically supported by “battery-only” systems. Battery technologies are inherently energy dense systems with limited power capability. Where energy transfer to the load is equal, primary and secondary chemistries have shown reduced performance when subjected to pulsed loading as compared to operation at low constant rates. Primary chemistries exhibit reduced discharge time or usable capacity while secondary chemistries suffer from both reduced usable capacity as well as reduced cycle life. The hybrid technology pairs the energy dense battery system with the power dense ESL Hybrid Power Management Unit (HPMU) to improve overall system performance. The HPMU contains ESL’s hybrid power management circuitry and a high-power Super Capacitor (SCap) element. The HPMU enables the battery system to operate at a reduced rate supporting the baseline load and the recharge of the SCap while the SCap is utilized to support peak pulse requirements of the load. The result is improved lifetime, reduced battery heating, and extended cycle life of the battery system.
