文摘
Two common tests for observing battery open circuit voltage performance are compared. The temperature dependency of the OCV-SOC relationship is investigated. Two estimators are evaluated in terms of accuracy and robustness for estimating battery SOC. The incremental OCV test is better to predetermine the OCV-SOCs for SOC online estimation.
