OPTIMIZED ENERGY TRANSFER ALGORITHM FOR ENERGY STORAGE ARRANGEMENT

摘要

The method for operating an energy storage arrangement with a plurality of serially connected storage cells according to the present invention comprising following steps: Calculating the amount of energy to be transferred so that all cells reach a predetermined state-of-charge and calculating the energy losses in the energy transfer units. Determining the load profile and calculating the remaining time (tTransfer, t'Transfer) until the energy storage arrangement reaches the predetermined state-of-charge. Calculating the energy transfer unit's power capability (PiTransfer, P'iTransfer) at the selected range of operation. Calculating the amount of energy to be transferred from/to each individual cell (EiTransfer, E'iTransfer). Calculating the individual state-of-charge (SoCIA, SoCIE) point for each cell at which the energy transfer among individual cells must be activated to reach predetermined individual state-of-charge at the same time.
