State-of-Charge (SoC)

State-of-Charge (SoC) refers to the current level of energy remaining in a battery, expressed as a percentage of its total capacity. Think of it like a fuel gauge for batteries: 100% means fully charged, while 0% indicates the battery is empty. SoC helps users understand how much power is left before needing to recharge. It’s an important measure in applications like electric vehicles and renewable energy systems, ensuring efficient use and timely recharging to maintain performance and prevent damage.
