  • Abstract Battery storage systems play an important role in integrating renewable energy into the grid, however they are less popular due to their high initial cost. When the state-of-health (SOH) of the batteries in Electric Vehicle (EV) are lower than 80%, they are not suitable for EVs. But, they still can be used in energy storage applications. If the used EV batteries could be utilized in battery storage system, it can significantly reduce the initial cost of storage system. In this thesis, a power optimizer concept is introduced to manage the batteries with varying levels of SOH and state-of-charge (SOC). The charging & discharging currents of individual battery packs are controlled to deliver the optimal power and energy capacity of the whole battery energy system. Study results indicate that using the proposed charging and discharging strategies, it can reduce the initial cost of storage system and increase use value of the batteries.
