Hybrid Electrical Energy Storage systems (HEES) are comprised of multiple banks of inhomogeneous EES elements with difference characteristics. They have been proposed to achieve desired performance metrics of an ideal energy storage device, i.e., high energy capacity, high output power level, low self-discharge, low cost, and long service life. Implementation of appropriate charge management policies enables efficient storage and retrieval of the electrical energy, attaining performance metrics that are close to the respective best values across the constituent EES elements in the HEES system.
