This manuscript proposes a new power management strategy implemented using the Rule based controller which considers the state of charge of the Li-ion batteries (SOC). The Li-ion batteries are used to provide a steady and constant power, function of the state of charge (SOC), enabling a higher efficiency and extending batteries lifespan. A typical standalone PV application is used to demonstrate and validate the performance of the proposed power management strategy.engBattery management systemDC-DC convertersHybrid energy storage systemsLi-ion batteriesPhotovoltaic productionSupercapacitorsjournal article10.1109/EEEIC.2018.8494598
