| Popis: | The article proposes a matching device between an accumulator battery and a voltage inverter in electric energy storage systems based on a reversible DC-DC converter with improved weight, size and cost indicators. Lithium-ion batteries are subject to tough operational requirements. The discharge of such batteries is not recommended to exceed their three-fold capacity (C), while the charge is limited to 0.5C, and low-frequency ripple components should not be present in the charging current. These requirements can be fulfilled with the help of the proposed matching device which is characterized by smaller dimensions and cost achieved due to the choke unit. The article proposes the calculation of the converter circuit and presents the simulation results obtained in the Psim simulation environment (the PowerSim environment). An economic assessment of the converter has been carried out. |
