Şarj Durumu (State of Charge, SoC) Nedir?
Şarj durumu (state of charge, SoC), aküde kalan elektrik enerjisinin bir göstergesidir. Yüzde 30 deşarj olmuş bir akünün SoC değeri yüzde 70’dir.

State of Charge (SOC): A key parameter in the electric vehicle is the SOC of the battery. The SOC is a measure of the residual capacity of a battery. To define it mathematically, consider a completely discharged battery.
Typically, the battery SOC is maintained between 20 and 95%.
A common mistake that people may make about a battery’s charge is that when a battery “goes dead,” the voltage goes from 12 to 0 V (for a 12 V battery). In reality a battery’s voltage varies between 12.6 V with a SOC of 100% to approximately 10.5 V with a SOC of near 0%. It is advised that the SOC should not fall below 40%, which corresponds to a voltage of 11.9 V. All batteries have a SOC vs. voltage curve which can be either looked up from the manufacturer’s data or determined experimentally. An example of an SOC vs. voltage curve of a lead acid battery is shown in Figure. Note that for a lithium-ion battery, the curve may be much flatter, especially for the mid-SOC range of 40–80%.
