Which acronym is used to indicate the level of charge in an EV battery?

The acronym SOC stands for "State of Charge," which is a crucial metric used to assess the level of charge in an electric vehicle (EV) battery. The SOC tells you how much energy is stored in the battery compared to its total capacity, typically expressed as a percentage. For example, a SOC of 100% means the battery is fully charged, while 50% indicates it has half of its total capacity remaining.

Understanding SOC is vital for both drivers and manufacturers, as it helps manage battery performance, optimize charging cycles, and estimate the remaining range of the vehicle. It also plays a critical role in ensuring the longevity of the battery by preventing overcharging and deep discharging, which can degrade battery health over time.

Other acronyms listed, such as ANSI (American National Standards Institute), EVA (Electric Vehicle Association), and DCM (Device Control Manager), do not pertain directly to the measurement of battery charge levels and serve different functions within the broader context of standards, associations, or device management in technology.
