Battery energy storage systems have traditionally been manufactured using new batteries with a good reliability. The high cost of such a system has led to investigations of using second life transportation batteries to provide an alternative energy storage capability. However, the reliability and performance of these batteries is unclear
Cell balancing circuits are important to extent life-cycle of batteries and to extract maximum power from the batteries. A lot of power electronics topology has been tried for cell balancing in the battery packages. Active cell balancing topologies transfer energy from the cells showing higher performance to the cells showing lower performance to balance
Energy Storage Systems are structured in two main parts. The power conversion system (PCS) handles AC/DC and DC/AC conversion, with energy flowing into the batteries to charge them or being converted from the battery storage into AC power and fed into the grid. Suitable power device solutions depend on the voltages supported and the power
Such modified topology is called Two Stages Interlinking Converter with Energy Storage Device (TSILC-ESD). The PMS applied in the hybrid AC/DC microgrid is based on the ILC control responsible for the DC microgrid formation, and the TSILC-ESD control, which provides ancillary services to the utility grid.

For most of the tested TCS prototypes, a ≈50 % reduction between the reactor energy density and storage material energy density was reported [3], [4]. Such a performance gap is often attributed by researchers to the ineffective heat and mass transfer in the reactive beds [5] .
The battery voltage depends upon the system power level. Lower power single phase systems commonly use 48-V battery, while higher power three phase systems use 400-V battery. Intermediate battery voltages are used infrequently. Systems with higher power range of string inverters could use 800-V battery for storage.
