摘要：
This paper proposes the online state-of-health (SOH) estimation algorithm for the electric vehicles (EVs) by using the aging tendency of the open circuit voltage (OCV). The proposed algorithm uses the aging tendency of OCV curve analyzed based on NMC-type battery cells which is installed in battery pack for EVs. The analyzed aging tendency of OCV is utilized to estimate the degraded current capacity by extracting OCV in real time with a low pass filter. The proposed algorithm is validated through informative experiment using NMC-type battery cells.
