What is the SOC range of general power lithium batteries?

The percentage of the capacity that can be released in the current battery according to the specified discharge conditions to the available capacity, and the percentage of the SOC state range is generally from 0% to 100%. However, considering the reaction characteristics of chemical batteries: threshold boundaries, static and dynamic differences, magnification differences, estimation accuracy differences, etc., SOC estimation should be set aside a buffer zone to ensure that the battery is always working in a safe area. The meaning of SOC is for power lithium battery cells. There is currently no unified meaning for power lithium ion battery systems. In actual use, the simpler method is to equivalent power lithium ion battery packs to battery cells. To ensure the safety of the battery, the SOC of the worst-performing battery cell is often used to mean the SOC of the battery pack. Power lithium battery.jpg The calculation method of power lithium battery SOC Part 1: The charging process can simulate and calculate the fully charged state of the battery according to the charging characteristic curve of the lithium battery (the relationship between the charging current, the voltage change curve and the battery capacity). The second part: the discharge process can simulate the remaining capacity of the battery according to the battery discharge characteristic curve.
