Parameter Determination of Lithium Titanate Battery for Rail Transit Based on OCV-SOC Characteristic Curve

The properties of lithium titanate battery for rail transport in different states are tested based on OCV-SOC characteristic curve in order to achieve the homogeneity of rail transit facilities. Here a study case is cited to reveal how about some parameters for battery under test such as the pressure and the capacity, etc. The results show that this approach has a good effect on the lithium titanate battery charge-discharge control with the best voltage limit determined. It is concluded that the best voltage limits for floating charge are favorable for the charge and discharge control of lithium titanate battery in rail transit.
