Quick SOH and SOC estimation for commercial 18650 Li-Ion Batteries
18650 Li-Ion batteries are used in a lot of applications. In this study, 18650 batteries were explored to have a method to estimate its SOH quickly. Batteries were discharged with a high current for a short period of time. According to the voltage histories for the period, the internal resistance and SOH could be derived. With the current and rated capacity, two parameters could be found. The relationship between SOH and SOC could be found. In short, the proposed method was able to estimate the SOH and SOC with data from high current discharging for a short period time.
