Lithium Ion Battery/Lithium Ion Capacitor Hybrid Portable Energy Storage Device for Pulsed Power Applications

摘要

A portable hybrid power system is presented that utilizes a lithium ion battery and lithium ion capacitor in a single solution. Integration is carried out through the use of a hybrid power management circuit board. The electronics allow for the system to act as both a portable power source and portable energy harvester. The hybrid system directly addresses pulse power applications characterized by peak power support where battery only solutions have exhibited reduced performance. Hybrid testing comparing battery and hybrid approaches have shown significant benefit when utilizing the hybridized system under pulsed power conditions.
