The relationship between battery SOC and voltage is straightforward – as the state of charge increases, the voltage of the battery also increases. When a battery is fully charged, it will have a higher voltage. Conversely, when a battery is discharged, the voltage will be lower. How can I determine the state of charge of my battery using voltage?
There is a direct relationship between the SOC and voltage of a battery. As the SOC decreases, the voltage also decreases, and vice versa. However, it is important to note that this relationship is not linear. The voltage curve of a battery is typically nonlinear, with different slopes at different charge levels.
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.
The OCV -SoC follows linear relation in Lead acid batteries while it''s no linear in Lithium-Ion Batteries as shown in Fig. 1 and Fig. 2 respectively. The open circuit voltage needs the battery to be in unloaded condition as it takes time for voltage to reach its steady state.
