This paper primarily proposes an SOH - SOC balancing control strategy for energy storage systems based on the characteristics and patterns of battery ageing.
SOC (State of Charge) is the percentage that represents the charge level of a battery in a solar power system. It indicates how much energy is stored in the battery compared to its full capacity. For example, if a battery’s SOC is at 80%, it means that the battery is 80% charged and 20% of its capacity is still available for charging.
In a solar energy storage system, proper SOC monitoring ensures that the battery operates within an optimal range, balancing the needs of the user with the health of the battery. Without accurate SOC management, the system could either overcharge or undercharge, reducing its efficiency and lifespan.
For a battery energy storage system (BESS), the State-of-Charge (SoC) is a key parameter. Due to the complexity of battery structure and electrochemical reaction, SoC is often difficult to obtain directly.
