Lithium-ion batteries (LiBs) are one of the promising technologies of choice for energy storage applications due to its high energy and power density. Under the guidance of Prof. Venkat R, the team is working on a power management control strategy for a standalone PV-Battery Energy Storage (BES) hybrid power system. The control algorithm tracks the Maximum Power Point of the solar-cells while avoiding overcharging of the LiBs under different solar radiation and load conditions.The framework (as shown in figure) also performs thermal management and proposes a strategy to minimize thermal degradation in the batteries. in a standalone solar-PV–BES hybrid power system. This is achieved using a physics-based electrochemical-thermal single particle model for simulating the battery. This model can capture the thermal aspects of degradation of the BES system. The BES system is better protected against thermally driven capacity fade using the proposed thermal management and control strategy that does not use any external cooling systems.Simulations for an entire year are performed using real-world solar insolation and household energy consumption data of a residential area in India to check the usefulness of this approach.
