| Abstract: | A model of steady-state characteristic parameters of Li-ion battery was proposed to achieve SOC (State-of-Charge) estimation. The model was established on Li-ion battery which had a rated capacity of 8 Ah used for HEV. Some fateful characteristic parameters for battery SOC estimation such as voltage, current, temperature, and etc, were chosen to constitute the Map. Some experiments (mainly multiple current charge and discharge tests and OCV-SOC tests) were designed to get these data. Use the methods of inte... |
