Hybrid Power Management Concept

Model 1041 Hybrid Operation Diagram


 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.

Application to Portable Systems and Devices

The Model 1041 Hybrid Power Management Unit is particularly applicable to portable communication devices. When battery power alone cannot meet power requirements, the batteries are stressed beyond their limits. The hybrid power unit allows batteries to operate at lower current level so that the operation can be achieved and the battery life is extended. Once the batteries are exhausted, they can be replaced, while the hybrid unit can be used again, repeatedly. The hybrid unit contains a 1500F LiC. The battery is sold separately allowing use of a customer supplied battery. Time extensions will vary with power requirements. Custom systems are available to meet specific power extension requirements.

Military Communications and Other Applications

Currently, extensive work has been done supporting military communications load profiles such as SATCOM (1min @ 100W, 9min @ 12W) and SINCGARS (1min @ 20W, 9min@ 6W). Additionally, the HPMU has been integrated into unmanned underwater vehicles hybridizing the thruster load used for station keeping or depth control which experiences pulsed loading on the order of 100W to 150W. Further applications with larger systems upwards of 250kW which use the lithium ion capacitors in a different hybrid architecture to provide load leveling support have been successfully completed.

Additional Capabilities and Uses

Existing system design supports nominal 12V battery systems as input with 12V or 24V output support. 60s @ 100W possible over full LiC voltage range. Higher power is possible over shorter pulse widths (shorter LiC operating voltage range). Supports bidirectional operation in which the system is able to regulate the battery during pulsed power loads and also when absorbing pulsed power from external sources. Note the hybrid technology is scalable to accommodate different sized systems in terms of energy and power required. The nominal 100W system provides the opportunity for hybridizing the intended battery chemistry/technology in a subscale setting for performance evaluation before moving to the full-sized system.
